Answer:
1157/198
(Decimal: 5.843434)
Step-by-step explanation:
The numeric values for the function are given as follows:
a) f(-5) = 14.
b) f(0) = 10.
c) f(5/2) = 8.
d) f(5a) = -4a + 10.
e) f(5a - 15) = -4a + 22.
<h3>How to find the numeric value of a function?</h3>
To find the numeric value of a function, we replace each instance of the variable by the desired value.
For this problem, the function is given by:
f(x) = -0.8x + 10.
Hence the numeric values are given as follows:
- f(-5) = -0.8(-5) + 10 = 14.
- f(0) = -0.8(0) + 10 = 10.
- f(5/2) = f(2.5) = -0.8(2.5) + 10 = 8.
- f(5a) = -0.8(5a) + 10 = -4a + 10.
- f(5a - 15) = -0.8(5a - 15) + 10 = -4a + 22.

We can think of this as an equality
5 Lawns = 8 Hours
If she needs 40 hours, you can multiply 8 hours by 5 to get 40, but now it's not balanced. So, you need to multiply 5 to the other side too so:
5 x (5) = 8 x (5)
Therefore she mows 25 Lawns in 40 Hours

Answer:
15 seconds
Step-by-step explanation:
Put the given heights in the equation and solve for t.
h(t) = -16t² +3600
0 = -16t² +3600 . . . . h(t) = 0 at ground level
16t² = 3600 . . . . . . . add 16t²
t² = 3600/16 = (60/4)² = 15² . . . . . divide by 16
t = 15 . . . . . . . . . . . . take the square root
It will take 15 seconds for the phone to hit the ground.
