which is the image for point p ( 7/4, -5/2) for a scale factor of 1/7
Answer:
(1/4, -5/14)
Step-by-step explanation:
point (7/4, -5/2) after a scale factor of 1/7 becomes
(7/4)*(1/7), (-5/2)*(1/7) =
(7*1)/(4*7), (-5*1)/(2*7) =
(1/4, -5/14)
Find an equation for the perpendicular bisector of the line segment whose endpoints are (-5,5) and -9,-9
Answer:
y= 3.5x+22.5
Step-by-step explanation:
The standard equation of a line a expressed as y = MX+c
m is the slope
c is the y-intecept
Get the slope
m = y2-y1/x2-x1
m = -9-5/-9+5
m = -14/-4
m = 7/2
Get the y- intercept
Substitute any of the point say (-5,5) and m = 7/2 into the equation y = MX+c
5 = 7/2(-5)+c
5= -35/2+c
5 =-17.5+c
c = 5+17.5
c =22.5
Get the required equation
Recall that y = MX+c
y= 3.5x+22.5

Jacob surveyed members of three different gyms and recorded the number of hours they exercised last week. The mean and standard deviation (SD), of the data he gathered, is shown in the table.
Gym A, Mean = 7. SD = 2.9
Gym b, Mean = 8, SD = 4.2
Gym c, Mean = 6, SD = 3.2
Use the information to complete the following statement.
The members of gym [A, B, or C] show the most consistency in the number of hours they exercised last week because the [mean, standard deviation] of this data set is the [lowest or highest]. inside brackets are the options
Answer:
A, Standard Deviation, Lowest
Step-by-step explanation:
I got it right lol
The members of gym A show the most consistency in the number of hours they exercised last week because the standard deviation of this data set is the lowest.
What is mean?"The mean is one of the measures of central tendency. Mean is nothing but the average of the given set of values."
What is standard deviation?"The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range."
Given, Gym A has the lowest value of SD = 2.9, Gym C has the second lowest vale of SD = 3.2 and Gym B has the highest value of SD = 4.2.
We know, standard deviation is measured with the help of the differences of a group of data and the mean.
Therefore, more the standard deviation is less, the data will be more consistent.
Therefore, Gym A has shown the more consistency in terms of number of hours exercised last week.

Barry needs $1,449 for summer camp. Two local clubs will each match what he saves. Barry has 3 months before he leaves for summer camp. How much does Barry need to save on his own each month to have enough for summer camp?
Answer:
$161 each month
Step-by-step explanation:
We first need to calculate the total that Barry needs to save on his own. Since the two clubs are matching the amount that he saves then we need to divide the final total by 3.
$1,449 / 3 = $483
Barry needs to save a total of $483 in order for the two clubs to match his savings so he can save the $1,449 he needs. Barry has 3 months to save this amount therefore we need to divide this by 3.
$483 / 3 = $161
Finally, we can see that Barry needs to save $161 each month to have enough for summer camp

What is meant by functions?A function from a set X to a set Y assigns exactly one element of Y to each element of X. The set X is known as the function's domain, and the set Y is known as the function's codomain. In mathematics, a function is a mathematical expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.A function is a relationship between a set of inputs and one output. Every function has its own domain, codomain, and range.When working on a project, it is common for some tasks to need to be repeated with different input. To ensure that the analyses are performed consistently, it is critical to wrap the code in a named function that is called each time it is required.Therefore,
The two graphs representing functions f and g are shown below. Option D) f (-3) > g (4)

What is Sine and Cosine function ?Sine, Cosine are the main functions used in Trigonometry and are based on a Right-Angled Triangle.
from 0 to 2π, sin (x) is increasing on the intervals (0, π/2) and (3π/2 , 2π), and decreasing on the interval (π/2 , 3π/2).from 0 to 2π, cos (x) is decreasing on (0 , π) increasing on (π , 2π).So common interval in which both sine and cosine functions are increasing is [tex](3\pi /2 , 2\pi )[/tex]

2. The perimeter of a college basket ball court is 96 m and the length is 14m
more than the width. What are the dimensions?
Step-by-step explanation:
A college basketball court is 96 feet by 50 feet. In meters this is approximately 29 meters by 15 meters. While you are correct that the length is 14 meters more than the width, the actual perimeter is 88 meters.
Answer:
Perimeter = 96 = 2 × (L+W)
96=2× (X+X+14)
96=2×(2x+14)
96=4x+28
96-28=4x

An investment of \$2,500 doubles in value every 15 years. The function f defined by f(x) = 2, 500(2 ^ (rx)) represents the value of the investment , in dollars, years after the investment is made , where r is a constant. What is the value of r? R =
Answer:
[tex]\dfrac{1}{15}[/tex]
Step-by-step explanation:
Given that:
Investment amount = $2500
Time in which it gets doubled = 15 years
Amount after 15 years = $5000 (As per given statement as it gets doubled)
Value of investment in dollars after [tex]x[/tex] years if investment:
[tex]f(x) = 2, 500(2 ^ {rx})[/tex]
[tex]r[/tex] is a constant.
To find:
Value of [tex]r[/tex].
Solution:
We are given that:
[tex]f(x) =\$5000[/tex]
[tex]x=15\ years[/tex]
Putting all the values in the given equation:
[tex]5000 = 2500(2 ^ {r\times 15})\\\Rightarrow 2 = 2 ^ {r\times 15}\\\Rightarrow r\times 15=1\\\Rightarrow r =\bold{\dfrac{1}{15}}[/tex]
Therefore, the value of [tex]r[/tex] is:
[tex]\dfrac{1}{15}[/tex]
