Answer:
I believe this is pathgorean theorem, which I did at the beginning of alegbra last year. It is basically finding the missing side of a triangle. (Trust me some of the easiest stuff you do all year) Below are my notes from last year. I hope it helps! Good Luck!!!
Step-by-step explanation:
Given two sides
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)
Answer:
3.1 seconds
Step-by-step explanation:
The time it will hit the ground is when the <em>height is equal to 0</em>. So we plug in 0 in h and solve the quadratic equation for t.

We will use the quadratic formula [
] to solve this.
a is -16
b is 40 , and
c is 30.
plugging these into the formula we get:

Since time cannot be negative, we take t = 3.1 as the value
So it will take 3.1 seconds to hit the ground (target)
