Answer:
The answer is 20 because if you're going from a negative number to a positive you are adding 20 not subtracting it also 10 + 10 is 20 :P
Step-by-step explanation: Hope this helps!
Don't modify the equation. It is true that f(3)= 288 for f(t) = -16t^2 +144t
the maximum height of the ball will be where the derivative is zero. In other words you could find the height of the ball by converting this into vertex form, or you could find it by calculating the time needed for the ball to reach its maximum height.
0=-32t+144
t=3 till max and max is 288
224=-16t^2 +144t
0= -16t^2+144t-224
t=2 but then the ball will reach 224 ft again at t=7
the ball reaches its maximum height at t=3 seconds and a parabola is symmetric, so at t=6 seconds it will contact the ground again.
Answer:
The patio is actually 24 feet long.
Step-by-step explanation:
Key words you need to know here are scale is 1 millimeter = 2 feet and patio is 12 millimeters long.
The question is asking how long is the actual patio, not in the scale drawing, in real life.
To solve this I'm going to set up a ratio, the scale being 1 ratio and the other ratio being 12 millimeters over blank. It's going to look like this :
=
To solve for x we cross multiply.
1(x) = 12(2)
x = 24
So the actual patio is 24 feet long.
