Find the limit if it exists. Picture provided
Answer:
b. -1
Step-by-step explanation:
When evaluating a limit at a specific value like this, just plug in the number and evaluate.
(2)³ - 3(2)² + 3
8 - 12 + 3
-4 + 3
-1
Answer:
b. [tex]-1[/tex]
Step-by-step explanation:
The given limit is
[tex]\lim_{x \to 2} (x^3-3x^2+3)[/tex]
This is the limit of a polynomial function so we plug in the value of x directly to obtain;
[tex]\lim_{x \to 2} x^3-3x^2+3=(2)^3-3(2)^2+3[/tex]
Evaluate
[tex]\lim_{x \to 2} x^3-3x^2+3=8-12+3[/tex]
This simplifies to
[tex]\lim_{x \to 2} x^3-3x^2+3=-1[/tex]
The correct choice is B.
How do you do this problem?
Answer:
Step-by-step explanation:
Part A
If it is compounded quarterly, the interest of 1.5 must be cut into a quarter of its present size. 1.5 //4 = 0.375 % per quarter.
In addition, the number of times that payment will be received is
4 quarters * 5 years = 20 quarters.
i = principle (1 + 0.375/100) ^20
i = principle (1 + 0.00375)^20
The principle = 4000 dollars.
i = 4000 * (1.00375)^20
i = 4000 * 1.07773
i = 4310.93
So she's tied up 4000 dollars to make 300 dollars.
Part B
I can't really give you an answer to this because I don't know if the 7% is compounded and over what period of time if it is, or if they mean 7% annually. There's a lot of variation in this question. Most people don't take money out of the market, so if it compounded, the formula would be
New Principle = starting amount (1.07)^4
New Principle = 4000 * 1.07^4
New Principle = 5243.18 so she would make about 4 times as much as the 300 she makes if she puts the money in a bond.
=============
If the interest is simple interest
Gain would be 0.07 * 4000 = 280 dollars.
Over four years = 4*280 = 1120 dollars.

Let's say that we had a 750 coyotes that were decreasing at a rate of 3% per year. How many years would it be until we had only 100 coyotes left? Show your work.
Answer:
Approximately after 66.15 years, there will be 100 coyotes left
Step-by-step explanation:
We can use the formula [tex]F=P(1+r)^t[/tex] to solve this.
Where
F is the future amount (F=100 coyotes)
P is the initial amount (P=750 coyotes)
r is the rate of decrease per year (which is -3% per year or -0.03)
t is the time in years (which we need to find)
Putting all the information into the formula we solve.
Note: The logarithm formula we will use over here is [tex]ln(a^b)=bln(a)[/tex]
So, we have:
[tex]F=P(1+r)^t\\100=750(1-0.03)^t\\100=750(0.97)^t\\\frac{100}{750}=0.97^t\\\frac{2}{15}=0.97^t\\ln(\frac{2}{15})=ln(0.97^t)\\ln(\frac{2}{15})=tln(0.97)\\t=\frac{ln(\frac{2}{15})}{ln(0.97)}\\t=66.15[/tex]
Hence, after approximately 66.15 years, there will be 100 coyotes left.
Rounding, we will have 66 years

There are 36 gold cards and 36 silver cards in a deck. The gold cards are numbered 1,3,5,... 71 and the silver cards are numbered 2.4.6,... 72. The cards are throughly shuffled and one card is randomly selected.
A. Find the probability of selecting a gold card or a card with a multiple of 12 on it. Show your work
B. Find the probability of selecting a silver card or a card with a multiple of 9 on it. Show your work.
A) multiples of 12 up to 72 ( 72 total cards)
12, 24, 36, 48, 60, 72 = 6 cards.
36 are gold.
Total gold cards and multiple of 12 = 36 + 6 =42
Probability of getting one of them is 42/72, which reduces to 7/12
B) 36 silver cards
Multiples of 9: 9, 18, 27, 36, 45, 54,63 = 7 cards
Silver cards are even and there is 3 even cards that are also multiples of 9, so subtract 3 from 7 to get 4.
Total silver cards and multiples of 9 = 36 + 4 = 40
Probability = 40/72 which reduces to 5/9
Answer:
Step-by-step explanation:
A.
Because there is no overlap between good card and card with a multiple of 12,
P(gold card or a card with a multiple of 12)
= P(gold card) + P(a card with a multiple of 12)
P(gold card)
= no. of gold cards / total no. of cards
= 36 / (36 + 36)
= 36 / 72
= 1/2
P(a card with a multiple of 12)
= no. of cards with multiples of 12 / total no. of cards
= (12, 24, 36, 48, 60, 72) / 72
= 6/72
= 1/12
P(gold card or a card with a multiple of 12)
= 1/2 + 1/12
= 7/12
B. There ARE overlaps between a silver card and a card with a multiple of 9,
P(silver card or a card with a multiple of 9)
= P(silver card) + P(a card with a multiple of 9) - P(silver card AND a multiple of 9)
P(silver card)
= no. of silver cards / total no. of cards
= 36 / (36 + 36)
= 36 / 72
= 1/2
P(a card with a multiple of 9)
= no. of cards with multiples of 9 / total no. of cards
= (9, 18, 27, 36, 45, 54, 63, 72) / 72
= 8/72
= 1/9
P(silver card AND a multiple of 9)
= no. of silver cards AND a multiple of 9 / total no. of cards
= (18, 36, 54, 72) / 72
= 4/72
= 1/18
P(silver card or a card with a multiple of 9)
= 1/2 + 1/9 - 1/18
= 10/18
= 5/9
he point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y – 4 = 1/4 (x – 8). What is the slope-intercept form of the equation for this line?
Answer:
[tex]y=\frac{1}{4}x+2[/tex]
Step-by-step explanation:
The point-slope form of the equation of a line that passes that through points (8, 4) and (0, 2) is given as;
[tex]y-4=\frac{1}{4}(x-8)[/tex]
To find the slope-intercept form of this line, we need to expand the point-slope form.
[tex]y-4=\frac{1}{4}x-2[/tex]
We now solve for y to obtain;
[tex]y=\frac{1}{4}x-2+4[/tex]
We simplify to obtain:
[tex]y=\frac{1}{4}x+2[/tex]
This equation is now in the form;
[tex]y=mx+c[/tex]
This is what we refer to as the slope-intercept form.

The string is 120 feet long and stretched taut. The kite string makes an angle of 70° with the ground. How high above the ground is the kite flying. Show Your Work
Answer:
112.76 feet
Step-by-step explanation:
This is a right triangle trig problem. We have the length of the string which serves as the hypotenuse of the triangle, and we also have the reference angle (the angle the string makes with the ground) and we are looking for the height of the height, which is also the height of the triangle, which is also the side opposite the reference angle. So it's our job now to figure out which trig ratio relates the side opposite the reference angle to the hypotenuse. That's the sin ratio (opposite/hypotenuse). Set it up like this:
[tex]sin(70)=\frac{x}{120}[/tex]
Multiply both sides by 120 and then do the math in degree mode on your calculator. That gives you that x = 112.7631145

Each month, Kaisorn deposits $50.00 onto her public transportation card. It costs her $2.50 per trip to ride the subway. Thom deposits $40.00 on his public transportation card. It costs him $2.00 per trip to ride the subway. If x represents the number of trips and y represents the amount remaining in each account, which system of equations represents their transportation costs? 50 − 2.5x = y 40 − 2x = y 50 + 2.5x = y 40 + 2x = y 50 − 2.5y = x 40 − 2y = x 50 + 2.5y = x 40 + 2y = x
Answer:
For Kaisorn: [tex]y=50-2.50x[/tex]
For Thom: [tex]y=40-2x[/tex]
Step-by-step explanation:
Each month, Kaisorn deposits $50.00 onto her public transportation card.
It costs her $2.50 per trip to ride the subway. Means 2.50x
Thom deposits $40.00 on his public transportation card. It costs him $2.00 per trip to ride the subway. Means 2x
Let x represents the number of trips
Let y represents the amount remaining in each account.
Then the system of equations represents their transportation costs are :
For Kaisorn: [tex]y=50-2.50x[/tex]
For Thom: [tex]y=40-2x[/tex]

Step-by-step explanation:
If you add up the measures of the arcs it is 158. That means BC is 202 degrees. Divide it by 2 to find the angle. For the second answer, remember the question did not specify if the arcs were major or minor so you can flip them around.
Answer:
m∠BAC is 101° or 36°.
Step-by-step explanation:
Given,
[tex]m(\widehat{AB})=115^{\circ}[/tex]
[tex]m(\widehat{AC})=43^{\circ}[/tex]
To find : The measurement of angle BAC,
Let O be the center of the circle.
Since, here we have to cases ( shown in diagram ),
In Case 1 :
[tex]m\angle BOC = 360^{\circ}-[m(\widehat{AB})+m(\widehat{AC})][/tex]
[tex]=360^{\circ}-(115^{\circ}+43^{\circ})[/tex]
[tex]=360^{\circ}-158^{\circ}[/tex]
[tex]=202^{\circ}[/tex]
By the central angle theorem,
[tex]m\angle BAC = \frac{m\angle BOC}{2}[/tex]
[tex]=\frac{202^{\circ}}{2}=101^{\circ}[/tex]
In Case 2 :
[tex]m\angle BOC = m(\widehat{AB})-m(\widehat{AC})[/tex]
[tex]=115^{\circ}-43^{\circ}[/tex]
[tex]=72^{\circ}[/tex]
Again by the central angle theorem,
[tex]m\angle BAC = \frac{m\angle BOC}{2}[/tex]
[tex]=\frac{72^{\circ}}{2}=36^{\circ}[/tex]

#SPJ2
Final answer:
Each of the four children, including Joelle, will receive 64 pieces of candy after dividing the total of 256 pieces evenly among them.
Explanation:
To find out how many pieces of candy each child receives, we need to divide the total number of pieces by the number of children. Joelle and her three siblings make a group of four children in total. They have accumulated 256 pieces of candy. To divide this evenly, we do the following calculation:
Divide the total number of candies (256) by the number of children (4).
The division gives us the result 64 pieces of candy for each child.
Therefore, each child, including Joelle, will receive 64 pieces of candy.
A bakery has 63 donuts and 36 muffins for sale. What is the ratio of muffins to donuts?
The ratio of muffins to donuts in the bakery is 4:7, calculated by dividing the number of muffins (36) by the number of donuts (63).
To find the ratio of muffins to donuts, we divide the number of muffins by the number of donuts.
Given:
- Number of donuts: 63
- Number of muffins: 36
Ratio of muffins to donuts:
[tex]\[ \text{Ratio} = \frac{\text{Number of muffins}}{\text{Number of donuts}} \][/tex]
[tex]\[ \text{Ratio} = \frac{36}{63} \][/tex]
We can simplify this ratio by finding the greatest common divisor (GCD) of 36 and 63, which is 9.
[tex]\[ \text{Ratio} = \frac{\frac{36}{9}}{\frac{63}{9}} \][/tex]
[tex]\[ \text{Ratio} = \frac{4}{7} \][/tex]
So, the ratio of muffins to donuts is 4:7 .
The ratio of muffins to donuts is [tex]\( \frac{4}{7} \)[/tex].
To find the ratio of muffins to donuts, we divide the number of muffins by the number of donuts:
[tex]\[ \text{Ratio of muffins to donuts} = \frac{\text{Number of muffins}}{\text{Number of donuts}} \][/tex]
Given that the bakery has 63 donuts and 36 muffins, we can substitute these values into the formula:
[tex]\[ \text{Ratio of muffins to donuts} = \frac{36}{63} \][/tex]
Now, we can simplify this fraction:
[tex]\[ \frac{36}{63} = \frac{4 \times 9}{7 \times 9} = \frac{4}{7} \][/tex]
So, the ratio of muffins to donuts is [tex]\( \frac{4}{7} \)[/tex].

Item 16 Simplify the expression. 5+8(3+x)
First, to simplify the expression 5 + 8(3 + x), distribute the 8 to everything inside the parentheses to get 5 + 24 + 8x. Then, combine the numerical terms to get the answer 29 + 8x.
Explanation:The expression you are asked to simplify is 5 + 8(3 + x). To do this, you'll need to use the distributive property, which allows you to multiply a number outside a set of parentheses by every term inside the parentheses.
Start with the expression: 5 + 8(3 + x)
Before adding, you'll need to multiply eight by every term inside the parentheses, three, and x:
5 + 8*3 + 8*x
That changes your expression to:
5 + 24 + 8x
Now, you need to combine like terms (add together the numbers that are not attached to variable x):
5 + 24 = 29
So, the simplified version of the expression is:

Step-by-step explanation:
Given f(x)=7x^9 , find f^1(x). Then state whether f^1f(x) is a function.
a : y=(x/7)^1/9 ; f^1(x) is a function.
b : y=(x/7)^9 ; f^1(x) is not a function
c : y=(x/7)^1/9 ; f^1(x) is not a function
d : y=(x/7)^9 ; f^1(x) is a function
Answer:
A
Step-by-step explanation:
Edge 2021
The inverse function of f(x) = 7x^9 is found to be f^{-1}(x) = (x/7)^{1/9}. By substituting f(x) into its inverse, we can verify that f^{-1}(f(x)) = x, which shows that the composition is indeed a function. Therefore, the correct answer is option a.
The student has asked to find the inverse function of f(x) = 7x^9 and determine if the composition of the original function and its inverse is a function. The inverse function, denoted as f^{-1}(x), undoes the action of the original function. To find the inverse, we replace f(x) with y, switch the roles of x and y, and then solve for y:
Start with y = 7x^9.Switch x and y to get x = 7y^9.Divide both sides by 7 to get x/7 = y^9.Take the ninth root of both sides to solve for y, yielding y = (x/7)^{1/9}.This gives us option a: y = (x/7)^{1/9}. To check if f^{-1}(f(x)) is a function, we substitute f(x) into the inverse, resulting in f^{-1}(7x^9) = (7x^9/7)^{1/9} = x, which is indeed a function. Therefore, f^{-1}(x) is a function, and option a is correct.
Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph.
y=-1 tan 1/10 x+4
Answer:
Reflection across x-axis, horizontal stretch by a factor of 10
and vertical translation up 4 units ⇒ answer (c)
Step-by-step explanation:
* The basic function of tanФ is
# y = tanФ
1- If y = -tanФ ⇒ reflect y over the x-axis
2- If y = tan(-Ф) ⇒ reflect y over the y-axis
3- If y = tan(Ф - k) ⇒ shift y right k units
4- If y = tan(Ф + k) ⇒ shift y left k units
5- If y = tanФ + k ⇒ shift y up k units
6- If y = tanФ - k ⇒ shift y down k units
7- If y = k tanФ ⇒ multiply y-values by k
(k > 1 stretch, 0 < k < 1 compressed vertical)
The scale factor is k
8- If y = tan(kФ) ⇒ divide x-values by k
(k > 1 compressed, 0 < k < 1 stretch horizontal)
The scale factor is 1/k
* Lets solve the problem
∵ y = -tan(1/10)x + 4
* We will use rules number 1 , 5 and 8
∴ Reflect y over the x-axis, shift y up k units and stretch
horizontal by scale factor is 1/k (0 < k < 1)
∴ Reflection across x-axis, horizontal stretch by a factor of 10
and vertical translation up 4 units
If a = 5 centimeters, w = 10 centimeters, and h = 6 centimeters, what is the area of the decorative paper he will require?
Final answer:
The area of decorative paper needed, given the dimensions of length and width, is calculated as 50 square centimeters.
Explanation:
To answer the question about the area of decorative paper required, we need to use the formula for the area of a rectangle which is length times width. However, the given dimensions of a = 5 centimeters, w = 10 centimeters, and h = 6 centimeters seem to describe a box or a prism rather than a flat piece of paper. If the decorative paper is meant to cover the side of the box, then the relevant dimensions are likely length and width, not including the height. Assuming the decorative paper is to cover a flat surface, the formula for the area is A = length × width. Therefore, the required area of decorative paper is A = 5 cm × 10 cm = 50 square centimeters.
