1. Pool Dimensions. The area of a rectangular
Irina18 [472]

Answer: I think the length is 60.25 yd and the width is 19.75 yd

Step-by-step explanation: I formed a equation using the information that has been given.

Width : X

length : 1 + 3x

equation : (1 + 3x) + x = 80

Then, I added the like pairs ( 3x+x ). After, I subtracted 1 from 80 and got 79. Then I divided 79 and 4 (79/4) to get 19.75, which is my x value. later, I substituted the x value to the equation and received my answer.

Sarah creates the graph of function g by applying a transformation to function f.
ss7ja [257]

The transformation on function f is (c) a vertical compression by a factor of 1/2

<h3>How to determine the transformation?</h3>

The functions are given as:

f(x) = 2^x

g(x) = 1/2(2^x)

The above means that:

g(x) = 1/2 * f(x)

The factor multiplied by f(x) to get g(x) is:

k = 1/2

The above factor is less than 1 but greater than 0.

This represents a vertical compression

Hence, the transformation on function f is (c) a vertical compression by a factor of 1/2

A particle moves in a straight line so that its velocity at time
riadik2000 [5.3K]

Answer:

s(2) = 7.75

Step-by-step explanation:

given the velocity v(t) = t^3

we can find the position s(t) by simply integrating v(t) and using the boundary conditions s(1)=2

s(t) = \int {v(t)} \, dt\\ s(t) = \int {t^3} \, dt\\s(t) = \dfrac{t^4}{4}+c

we know throught s(1) = 2, that at t=1, s =2. we can use this to find the value of the constant c.  

s(1) = \dfrac{1^4}{4}+c\\4 = \dfrac{1^4}{4}+c\\c = 4-\dfrac{1}{4}\\c = \dfrac{15}{4} = 3.75

Now we can use this value of t to formulate the position function s(t):

s(t) = \dfrac{t^4}{4}+\dfrac{15}{4}\\

this is the position at time t.

to find the position at t=2

s(2) = \dfrac{2^4}{4}+\dfrac{15}{4}\\

s(2) = \dfrac{2^4}{4}+\dfrac{15}{4}\\

s(2) = \dfrac{31}{4} = 7.75

the position of the particle at time, t =2 is s(2) = 7.75
