Step-by-step explanation:
thr standard form for a quadratic equation is:
ax²+bx+c
in this example, a=1, b=(-1), c=(-42)
Let x be the distance (in feet) along the road that the car has traveled and h be the distance (in feet) between the car
and the observer.
(a) Before the car passes the observer, we have dh/dt < 0; after it passes, we have dh/dt > 0. So at the instant it passes the observer we have
dh/dt = 0, given that dh/dt varies continuously since the car travels at a constant velocity.
Yes, they are equivalent. Another equivalent fraction would be any fraction that equals to 1. Eg. 9/9
Answer:
y = 4000 - 70x
Linear function.
Step-by-step explanation:
Let x = number of weeks.
In 1 week, he withdraws $70.
That means -70 in 1 week.
After the second week, he will have withdrawn 2 times $70, or
-70 × 2
After 3 week, he will have withdrawn -70 × 3
After x weeks, he will have withdrawn $70 × x,or simply -70x.
He starts with 4000, so after x weeks, he has 4000 - 7x.
Let y = the amount of money at week x.
The equation is
y = 4000 - 70x
This is a linear function.

Hello!</h2>
The answer is:
1017.88 square feet are blue.
<h2>Why?</h2>
To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.
We need to remember that we can calculate the area of any circle using the following formula:
Now, we know that the diameter of the bottom is equal to 36 feet, so, we can calculate the radius of the bottom using the following formula:
So,
Then, calculating the area we have:
Hence, we have that 1017.88 square feet are blue.
Have a nice day!
