These tables of values represent continuous functions. For which function will the y-values be the greatest for very large values of x?
(PLEASE HELP ME NEED ANSWER ASAP)
Answers
Answer:
(C) This function is an exponential.
Step-by-step explanation:
Exponentials are the fastest growing functions. In this case, the values in table (C) exhibit an exponential growth in that for every increase in x there is a tripling of the previous value. This would correspond to x being a power of the base 3.
Generally, the y-values will be greatest for very large values of x in increasing continuous functions such as y = x^2. To identify exactly which function among your tables has this property would require reviewing the actual tables.
Explanation:It's quite difficult to give you an accurate answer without having access to the actual tables of values. However, we can go by a general principle that in mathematics, specifically in the study of continuous functions, the y-values can be greatest for large values of x in case of increasing functions. These are functions where the value of y (or the output) increases as the value of x (or the input) increases. For instance, the function y = x^2 is an increasing function for x greater than 0. As x approaches infinity, so does the value of y. Therefore, the function that represents this behaviour will yield the greatest y-values for very large values of x. However, without knowing the precise functions represented by your tables it is impossible to give a definite answer.

if you flip a fair coin 6 times,what is the probability that you will get exactly 4 tails
Answers
The probability of getting exactly 4 tails when flipping a fair coin 6 times is 0.234375, or about 23.44%.
Explanation:To find the probability of getting exactly 4 tails when flipping a fair coin 6 times, we can use the binomial probability formula. The formula is:
P(X=k) = C(n, k) * p^k * (1-p)^(n-k)
Where:
P(X=k) is the probability of getting k tails (in this case, k=4)n is the number of trials (in this case, n=6)p is the probability of getting a tail on a single trial (in this case, p=0.5)C(n, k) is the number of combinations of n things taken k at a time (in this case, C(6, 4) = 15)Plugging these values into the formula, we get:
P(X=4) = 15 * 0.5^4 * (1-0.5)^(6-4) = 15 * 0.0625 * 0.25 = 0.234375
So, the probability of getting exactly 4 tails when flipping a fair coin 6 times is 0.234375, or about 23.44%.

In △ABC, CM is the median to AB and side BC is 12 cm long. There is a point P∈ CM and a line AP intersecting BC at point Q. Find the lengths of segments CQ and BQ , if P is the midpoint of CM
Answers
Answer:
CQ=4 cm, BQ=8 cm
Step-by-step explanation:
In given triangle ABC draw the line MD parallel to the AQ.
1. Consider triangle AMD. In this triangle PQ║MD (build) and CP=PM (P is midpoint of CM). Then by the triangle midline theorem, line PQ is midline of triangle AMD and CQ=QD.
2. Consider triangle BAQ. In this triangle AQ║MD and AM=MB. Then by the triangle midline theorem, line MD is midline of triangle BAQ and BD=QD.
Hence, CQ=QD=BD. Since BC=12 cm and
BC=BQ+QD+BD,
then
[tex]CQ=QD=BD=\dfrac{12}{3}=4\ cm.[/tex]
Note that
BQ=BD+QD=4+4=8 cm.
Final answer:
By examining the properties of median CM and midpoint P, we conclude that segment CQ is equal to QB, and both are 6 cm long in △ABC since CM bisects AB and BC is given as 12 cm.
Explanation:
The problem involves a triangle △ABC with CM being a median to side AB, and a line segment AP that intersects BC at point Q. According to the given information, P is the midpoint of CM, which implies that CP is equal to PM. Because BC is 12 cm in length, and CM is a median, we deduce that M is the midpoint of AB. This fact leads us to conclude that the triangles △CMB and △CMA are congruent by the Side-Side-Side (SSS) postulate, which means that CQ is equal to QB, and both are 6 cm long since Q lies on BC.

Which equation represents the line shown on the graph?
Answers
Answer:
y=2x
Step-by-step explanation:
The equation for slop-intercept form is y=mx+b where m is the slope and b is the y-intercept.
2 represents the rise/over since you rise 2 units (up) and run 1 unit (to the right). So the slope is 2/1 or just 2, and then you multiply it by x to get 2x.
The line starts at the origin (0,0), so the y-intercept would be 0. They didn't say y=2x+0 because the + 0 wouldn't change the line.
The equation that represents a line on a graph can be determined using the slope-intercept form, y = mx + b. To find the equation, you need to determine the slope and the y-intercept.
Explanation:The equation that represents a line on a graph can be determined using the slope-intercept form, y = mx + b. In this form, m represents the slope of the line and b represents the y-intercept (the point where the line intersects the y-axis).
To find the equation of the line shown on the graph, you need to determine the slope and the y-intercept. You can do this by selecting any two points on the line and using their coordinates to calculate the slope, and then substituting one of the points into the equation to solve for the y-intercept.
Once you have the slope and y-intercept values, you can substitute them into the slope-intercept form to write the equation of the line.

A sporting good store is offering an additional 30% off all clearance items and she purchases a pair of running shoes on clearance for $65 if the shoes originally cost $85 what was her total discount?
Answers
Answer:
Total discount = $39.50
or 46.47 %
Step-by-step explanation:
First we need to figure out what she will pay for the shoes. She is getting 30 percent off the 65 dollars.
Discount = price * percent off
= 65*.3
= 19.50
The cost of her shoes is the price minus the discount.
Cost = 65- 19.5
= 45.50
To find the total discount, take the original price and subtract the final cost.
Total discount = 85-45.50
= 39.50
To find the total percent discount, we use the formula
total percent discount = (original - final)/original * 100
= (85- 45.50)/85 * 100
= 39.5/85*100
= 46.47%
John was traveling 1700 feet in 20 seconds. How fast was the car going in miles per hour
Answers
John was traveling at a speed of 57.91 miles per hour when he covered a distance of 1700 feet in 20 seconds.
Explanation:To calculate the speed at which John was traveling in miles per hour, we will convert the given distance to miles and the time to hours, then divide the distance by the time. There are 5280 feet in a mile and 3600 seconds in an hour.
First, convert 1700 feet to miles:
1700 feet × (1 mile / 5280 feet) = 0.322 milesNext, convert 20 seconds to hours:
20 seconds × (1 hour / 3600 seconds) = 0.00556 hoursFinally, calculate the speed in miles per hour:
Speed = distance / timeSpeed = 0.322 miles / 0.00556 hours = 57.91 miles per hour (rounded to two decimal places)So, John was traveling at 57.91 miles per hour.

If Petrol cost 1.20 per gallon how much would 5 3/4 cost?
Answers
Answer:
Step-by-step explanation:
1.20 x 5.75
=$6.90
The cost of petrol is given per gallon. Therefore, to find the cost of 5 3/4 gallons of petrol, multiply the cost per gallon which is 1.20 by the number of gallons, 5 3/4, that gives 6.90. Hence, 5 3/4 gallons of petrol would cost 6.90.
Explanation:To find out the cost of 5 3/4 gallons of petrol, we first need to understand that the cost is listed per gallon. This means that for every gallon, you pay 1.20. So, to calculate the cost of 5 3/4 gallons, we just need to multiply the cost per gallon by the number of gallons.
So, the cost of 5 3/4 gallons would be: 1.20 (cost per gallon) x 5 3/4 (number of gallons) = 6.90.
Therefore, 5 3/4 gallons of petrol would cost 6.90.

The equation of a circle is (x−10)2+(y−8)2=256. What is the center of the circle? Enter your answer in the boxes.
Answers
Answer:
(10,8)
Step-by-step explanation:
The equation of a circle has the following form:
[tex](x-h)^2+(y-k)^2=r^2[/tex] where (h,k) is the center of a circle with radius r.
Our equation is:
[tex](x-10)^2+(y-8)^2=256[/tex]
The center is (10,8).
The center of the circle given by the equation (x−10)² + (y−8)² = 256 is (10, 8). This can be derived from the standard form of a circle's equation. Therefore, the coordinates are (10, 8).
The given equation of the circle is (x−10)² + (y−8)² = 256.
This equation is in the standard form of a circle's equation, (x−h)² + (y−k)² = r², where (h, k) represents the center and r is the radius.
In this case, the values of h and k can be directly identified from the equation: h = 10 and k = 8.
Therefore, the center of the circle is at the coordinates (10, 8).
At present a man is 5 times as old as his son, in 13 years time he will be three times as old as his son. Find the man's present age?
Answers
Answer:
65
Step-by-step explanation:
let the son's age be x then the man's age is 5x
In 13 years
son's age = x + 13 and man's age = 5x + 13 and he is 3 times as old as son
5x + 13 = 3(x + 13)
5x + 13 = 3x + 39 ( subtract 3x from both sides )
2x + 13 = 39 ( subtract 13 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13 ← son's present age
5x = 5 × 13 = 65 ← man's present age
Answer:
The man's present age is 65.
Step-by-step explanation:
Let x = the man's age and y = his son's age.
In 13 yr, their ages will be x + 13 and y + 13, respectively.
We have two conditions:
(1) x = 5y
(2) x + 13 = 3(y + 13) Remove parentheses
x + 13 = 3y + 39 Subtract 13 from each side
(3) x = 3y + 26 Substitute (1) into (3)
5y = 3y + 26 Subtract 2y from each side
2y = 26 Divide each side by 2
(4) y = 13 Substitute (4) into (1)
x = 5 × 13
x = 65
The man's present age is 65.
Escape what is on sale for 60% off the regular $80 price what is the sales price
Answers
Answer:
$32 is the sales price.
Step-by-step explanation:
First, change the percentage to a decimal.
60% = 60/100 = 0.6
Next, multiply 0.6 with the regular price ($80)
80 x 0.6 = 48
$48 is the discount. Subtract from the original price
80 - 48 = 32
$32 is the sales price.
~
Answer:
$32
Step-by-step explanation:
The sales price = original price - original price * discount rate
Factor out the original price
sales price = original price (1 -discount rate)
We know the original price is 80
We know the discount rate is 60% = .6
Substitute these values in
sales price = 80 (1-.6)
sales price = 80 * .4
sales price = 32
