is the functions that determines the height of the ball in Feet, after x seconds being thrown.
so for example to calculate how many feet above the ground in the ball 5 seconds after being thrown, we calculate f(5)
feet
to solve our problem we need to find x such that f(x)=0
so we solve :
using the quadratic formula, le a=1, b=-7, c=-8
so
, which cannot be the solution to our problem.
Answer: 8 s
Answer:
(x - 6)^2 + (y + 4)^2 = 4
Step-by-step explanation:
formula for a circle
( x - h )^2 + ( y - k )^2 = r^2
(h,k) is the center
r is the radius
(6,-4) is center
2 is radius
Substitute in numbers and watch the negatives.
Answer:
-7?
Step-by-step explanation:
I mean, is the question 20 - 27 =? Or it's something else? Lol.
20 - 27 = -7, it's very straightforward cannot write it in more detailed way. When we substract a number from another and the first one is smaller the result is a negative number. Imagine someone sells up to 3 apples, you ask him to give you 5. He gives you all 3 of his so he has 0 but you force him to go and get another 2 for you. He lost another 2, so he has less than 0 now. He has -2 apples: 3 - 5 = -2.
Now, I don't know if this is the question or these are set of exercises you must solve and your picture just didn't upload. Let me know if you need help with anything else.
The answer to your question is
