The diving from a cliff can be expressed in the equation H = Ho + vot - 1/2 g t^2 where vo as initial velocity is equal to zero since this is a free fall. g is equal to 32.2 ft/s2 as the acceleration due to gravity and Ho is equal to 40 feet. The expression now becomes H = 40- 16.1 t^2. When t is 1 second, H is equal to 23.9 feet. The total time of the diver is 0 = 40 - 16.1 t^2 or t equal to 1.58 seconds.
<u>Answer:</u>
x = 8
<u>Explanation:</u>
-x + 1 = -7 Subtract one from each side
-x = -8 Divide each side by -1 to get x by itself
x = 8
It’s the first one! The table shows X going up and Y going down, so the slope would be negative!
Answer:
The answer is 6x^2-8x+2
Step-by-step explanation:
To find the area, you have to multiply the length by the width.
You will get the equation of (6x-2)(x-1). Then, you multiply and find the answer, 6x^2-8x+2.
p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify
p(x) = 8x-10
p(10) = 8*10-10 .... every x is replaced with 10
p(10) = 80-10
p(10) = 70
So the profit is $70
