slope = (4 - (-5) / (-1 - 2) = (4 + 5) / -3 = -9/3 = -3 <==
Answer: 34.54feet
Step-by-step explanation:
Thw circumference of the pool will be calculated by using the formula:
= 2πr
where
π = 3.14
r = 5.5
Therefore, circumference = 2πr
= 2 × 3.14 × 5.5
= 34.54feet
Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.
Answer:
The quadratic polynomial with integer coefficients is 
.
Step-by-step explanation:
Statement is incorrectly written. Correct form is described below:
<em>Find a quadratic polynomial with integer coefficients which has the following real zeros: </em>
<em>. </em>
Let be 
and 
roots of the quadratic function. By Algebra we know that:
(1)
Then, the quadratic polynomial is:
The quadratic polynomial with integer coefficients is .
The equation would just be x=8 since the x of both points is 8.
