0.88 because 25 *4 = 100 and 22*4= x
x
=88
Ans: 0.88
Answer:


Step-by-step explanation:
Given

Solving (a): Equation when it hits the ground.
This means that 
So, we have:


Solving (b): The value of t in (a)

Using quadratic formula, we have:

This gives:




Split



Time can't be negative; So:

Answer:
Step-by-step explanation:
570000 to the nearest ten thousand
Y=40x since y intercept is 0 and slope is 40
The function f(x)=-3x follows a linear form y=ax+b, where a is the slope and b is the y-intercept. From our function:
f(x)=-3x
f(x)=-3x+0
slope, a=-3 and y-intercept is 0. This implies that the function is a linear function, thus the domain and range will be:
domain:
(-∞,∞)
Range:
(-∞,∞)
