If one zeros is x= -7 then the other zero is x=5
Step-by-step explanation:
We are given the function: 
If one zeros of the function is x=-7 we need to find other zero of the function.
We can find zeros of the quadratic equation by factorizing the equation

Factorizing the quadratic equation:

So, if one zeros is x= -7 then the other zero is x=5

A natural number is a positive integer, example, 1,2,5,299 etc.
A rational number is a number that can be expressed as a fraction of integers, such as 245/127, 1/2, 5/1,8/1,...
Since a natural number can be expressed as a fraction of integers, so
a natural number IS a rational number.
Answer:
Whats the question
Step-by-step explanation:
The brick will fall to the ground after 9 secs.
<h3>What are quadratic equations?</h3>
Given the equation for height as a function of time is h(t) = -16t2 + 1,296
The height of the brick on the ground is h(t) = 0. Substitute h(t) = 0 into the equation as shown:
Subtract 1296 from both sides
-16t² + 1,296 - 1296 = 0 - 1296
16t² = 1296
t² = 1296/16
t² = 81
t = 9secs
Hence the brick will fall to the ground after 9 secs.
