B(-5,1) is one end point of the segment and M(-3,3) is the midpoint of a segment what are cordnates of point A

Answers

Answer 1

Answer:

(-1,5)

Step-by-step explanation:

Let the coordinates of point A be (a,b).

We have that B is at (-5,1)

Assuming M(-3,3) is the midpoint of the segment AB, then

[tex](-3, 3 )= ( \frac{a + - 5}{2}, \frac{b + 1}{2} )[/tex]

This means that:

[tex]- 3 = \frac{a + - 5}{2}[/tex]

and

[tex]3 =\frac{b + 1}{2}[/tex]

This implies that 2*-3=a-5 and 3*2=b+1

-6=a-5 and 6=b+1.

a=5-6 and b=6-1

a=-1 and b=5.

Therefore the coordinates of A are:

(-1,5)

Answers

Answer:

$0.85 per tomato

Step-by-step explanation:

A unit rate is the cost for one item. Like $0.99 for this one bag of skittles.

So $3.40 divided by four is $0.85.

The unit rate would be 0.85. If you divide 3.40 by 4 you 0.85

Which function represents g(x), a reflection of f(x)=4(1/2)^x
across the x-axis?

Answers

Answer:

[tex]g(x)=-4(\frac{1}{2})^x[/tex]

Step-by-step explanation:

Given:

The parent function is given as:

[tex]f(x)=4(\frac{1}{2})^x[/tex]

The function [tex]g(x)[/tex] is a reflection of the parent function about the x-axis.

Now, in order to find the function g(x), we need to use the rules of function transformations.

As per transformation rules, when a function is reflected about the x-axis, the function rule is given as:

[tex]f(x)\to-f(x)[/tex]

So, the new function or the reflected function is the negative of the original function.

Therefore, the reflected function [tex]g(x)[/tex] is given as:

[tex]g(x)=-f(x)\\\\g(x)=-4(\frac{1}{2})^x[/tex]

Hence, the function that represents the reflection of the given function across the x-axis is [tex]g(x)=-4(\frac{1}{2})^x[/tex]

Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year. How much money will she earn in interest over 6 years?

A.

$4,050

B.

$1,500

C.

$3,845

D.
4,500

Answers

Option A

The simple interest earned over 6 years is $ 4050

Solution:

Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year

The formula for simple interest is given as:

[tex]Simple\ Interest = \frac{p \times n \times r}{100}[/tex]

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest

From given,

p = 15000

r = 4.5 %

n = 6 years

Substituting the values we get,

[tex]Simple\ Interest = \frac{15000 \times 4.5 \times 6}{100}\\\\Simple\ Interest = 150 \times 4.5 \times 6\\\\Simple\ Interest = 4050[/tex]

Thus simple interest earned over 6 years is $ 4050

Final answer:

Martha will earn $4,050 in simple interest over 6 years on her $15,000 savings account at a 4.5% annual rate. This is calculated using the simple interest formula, Interest = Principal × Rate × Time.

Explanation:

To calculate the simple interest that Martha will earn over a period of 6 years, we will use the formula for simple interest: Interest = Principal × Rate × Time. Here, the principal amount is $15,000, the annual interest rate is 4.5% (which is 0.045 in decimal form), and the time is 6 years.

Let's plug these values into the formula:

Interest = $15,000 × 0.045 × 6

Interest = $15,000 × 0.27

Interest = $4,050

Therefore, the total amount of interest Martha will earn over 6 years is $4,050, which matches option A.

HELP!!! A cell phone is 132 mm long and 57 mm wide. What is ratio of the width and length in simplest form.

Answers

The ratio of width to length in simplest form is 19 : 44

Solution:

Given that, A cell phone is 132 mm long and 57 mm wide

Length of cell phone = 132 mm

Width of cell phone = 57 mm

We have to find the ratio of width and length in simplest form

[tex]\frac{Width}{Length} = \frac{57}{132}\\\\\text{Reduce to lowest terms }\\\\\frac{width}{length} = \frac{57 \div 3}{132 \div 3}\\\\\frac{Width}{Length} = \frac{19}{44}[/tex]

In ratio form, we know that,

[tex]\frac{a}{b} = a : b[/tex]

Writing in ratio form, we get

Width : length = 19 : 44

Thus the ratio of width to length in simplest form is 19 : 44

if angles of a triangle are 2 is to 3 is to 4 is to .find the value of each angle​

Answers

Answer:

Angles of triangle are 40°,60° and 80°.

Step-by-step explanation:

Given:

if angles of a triangle are 2 is to 3 is to 4.

Let the common factor between the angles be 'x'.

So we can say that;

Angle 1 = [tex]2x[/tex]

Angle 2 = [tex]3x[/tex]

Angle 3 = [tex]4x[/tex]

We need to find the value of each angle.

Solution:

Now we know that;

"Sum of all angles of triangle is 180°."

framing in equation form we get;

[tex]Angle \ 1+Angle\ 2+Angle \ 3 =180[/tex]

Substituting the values we get;

[tex]2x+3x+4x=180\\\\9x=180[/tex]

Dividing both side by 9 we get;

[tex]\frac{9x}{9}=\frac{180}{9}\\\\x=20[/tex]

Angle 1 = [tex]2x=2\times20=40\°[/tex].

Angle 2 = [tex]3x=3\times20=60\°[/tex]

Angle 3 = [tex]4x=4\times20=80\°[/tex]

Hence Angles of triangle are 40°,60° and 80°.

The volume, V, of gas varies inversely with the pressure, P, on it. If the volume is 320 cm^3 under pressure of 40 kg/cm^2, what pressure has to be applied to have a volume of 200 cm^3?



Fill in the blank:

Answer: _________ kg/cm^2

Answers

The pressure [tex]64kg/cm^{2}[/tex] has to be applied to have a volume of [tex]200cm^{3}[/tex]

Explanation:

According to Boyle's law, for a fixed amount of gas, the volume and pressure are inversely proportional.

[tex]P_{1} \cdot V_{1}=P_{2} \cdot V_{2}[/tex]

Substituting the values, we get,

[tex]40 \times 320=P_{2} \times 200[/tex]

Dividing both sides by 200,

[tex]\frac{40 \times 320}{200}=P_{2}[/tex]

Simplifying the terms, we get,

[tex]\begin{aligned}\frac{12800}{200} &=P_{2} \\64 &=P_{2}\end{aligned}[/tex]

Thus, the pressure [tex]64kg/cm^{2}[/tex] has to be applied to have a volume of [tex]200cm^{3}[/tex]

21+x=26 what is the answer I need it done step by step

Answers

Answer: x=5

Step-by-step explanation:

21+x=26 (you need to isolate x)

-21    -21 (inverse operation to isolate x)

(subtract 21 from 26)

x=5

Answer: x = 5

Step-by-step explanation: In this problem, we want to get x by itself on one side of the equation. Since we have 21 + x, in order to get x by itself, we must subtract 21 from the left side of the equation and when we subtract 21 from the left side of the equation, we must also subtract 21 from the right side of the equation in order to keep our equation balanced.

So on the left, +25 and -25 cancel eachother out and on the right, 26 - 21 simplifies to 5 so x = 5. To check our answer, we plug 5 back in for x in the original equation and we get 21 + (5) = 26 or 26 = 26 which is a true statement  so we know our answer is correct.

Which expression is equivalent to 0.18?

A. 1/9

B. 2/11

C. 1/11

D. 11/2


Side note I can do this my self but im too lazy. plus, if anyone wants some easy points just answer this question. I dont feel like dividing.

Answers

Final answer:

Among the options given, 2/11 is most similar to 0.18 when we convert these fractions to their decimal format. Remember that this is an approximation since 2/11 results in a repeating decimal.

Explanation:

The given expression is equivalent to 0.18. To find out which among the provided options this is equivalent to, we need to convert these fractions to decimal format. Let's start with A.
A. 1/9 is equal 0.111 repeating.
B. 2/11 equals approximately 0.1818 repeating.
C. 1/11 equals approximately 0.0909 repeating.
D. 11/2 equals 5.5.

Comparing these to our given expression of 0.18, we find that Option B (2/11) is most closely equivalent after rounding. It's worth noting the repeating decimal in 2/11, which is why it is an approximation rather than an exact equivalent.

Step-by-step explanation:

The height of the portrait without the frame is 1.5 times its width.

Let the height is 1.5w inches and width is w inches.

Now, the frame around the portrait is 2 inches wide.

So, the dimensions of the portrait with frame are (1.5w + 4) inches by (w + 4) inches.

Therefore, the area of the framed portrait will be  

(1.5w + 4)(w + 4)
