Answer:
A. -8 and 20
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Consider the graph of the quadratic function y = </em><em />
<em>What are the roots of the function?
</em>
<em>A. –8 and 20
</em>
<em>B. –40 and –8
</em>
<em>C. –8 and 8
</em>
<em>D. –40 and 20
</em>
My answer:
Given the function:
<em> y = </em><em />
<=> y = <em> </em>
Let convert to the factors form, the roots of the function must meet the following requirements:
- The two number that has the sum of 12 = -b
- The two number that has the product of -40 = c
In 4 possible answer, only <em>–8 and 20 is possible because: </em>
-8 + 20 = 12 = -b
-8*20 = -160 = c
So the factored form of the function is:
y = (x + 8)(x-20)
Hope it will find you well.
Answer:
The answer to your question is: -3 and 7
Step-by-step explanation:
To know if a value is a zero of the polynomial is necessary to find the prime factors of 84.
84 2
42 2
21 3
7 7
1
Then, the possible values are ±1, ±2, ±3, ±7.
After that, we evaluate each value in the polynomial, if the result is zero, that number is a root of the polynomial.
Example
(-3)³ - 8(-3)² - 5(-3) + 84
-27 - 72 + 15 + 84
- 99 + 99 = 0
Then, -3 is a zero of the polynomial
(7)³ - 8(7)² - 5(7) + 84
343 - 392 - 35 + 84
427 - 427 = 0
Then, 7 is a zero of the polynomial

Based on the distance of the pitcher's mound from the home plate, the path of the ball, and the height the ball was hit, the distance the outfielder threw the ball is C. 183.0 ft.
<h3>How far did the outfielder throw the ball?</h3>
Based on the shape of a mound, the law of cosines can be used.
The distance the ball was thrown by the outfielder can therefore be d.
Distance is:
d² = 60.5² + 226² - (2 x 60.5 x 226 x Cos(39))
d ²= 33,484.42ft
Then find the square root:
d = √33,484.42
= 182.9874
= 183 ft

First work out the nth term then the 100th term:
the difference between the numbers is: 5
and that zero term is: -2
so the nth term is: 5n - 2
-------------------------------------------------------------
now using the nth term we replace n with 100,
then we get: 498
the answer is the above in bold
hope it helped :)
