<span>Sasha
drove from her house to the grocery store in 20 minutes.
Her return trip took 15 minutes. IF the store is 7 miles from here house.
Find Sasha’s average speed for her round trip in miles per hour.
=> 20 minutes + 15 minutes = 35 minutes
=> 35 minutes is the time of her travel.
=> 7 miles is the distance.
We need to solve for the average speed.
Formula = Speed = distance / time
=> 7 / 35
=> 0.2
thus, her speed is 0.2 miles per minute (.2miles/min)

Answer:
No. This is a cubic.
Step-by-step explanation:
An exponential function is a function whose operation is a base with x as the exponent. Here int he function has a base of x and an exponent of 3. This is a polynomial specifically a cubic. An exponential in this function would be .
Answer: The interest rate was 9%.
Step-by-step explanation:
If principal amount P is invested at the rate of r percent with simple interest(I) for t years, the formula to find rate :
As per given,
P = $ 500, I = $45, t = 1 year
Substitute values in formula , we get
Hence, The interest rate was 9%.
Answer: 1597x-60/5
Step-by-step explanation:
The attached graph represents the location of the pH values 0 and 1
<h3>How to plot the points?</h3>
The given parameters are:
pH value 0 = (1, 0)
pH value 1 = (0.1, 1)
This means that we plot a point at the coordinate (1, 0) and another point at the coordinate (0.1, 1).
