Answer:
h(x) = (x + 5)² - 18
Step-by-step explanation:
Given
h(x) = 7 + 10x + x² = x² + 10x + 7
To obtain vertex form, use the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² + 10x
h(x) = x² + 2(5)x + 25 - 25 + 7
= (x + 5)² - 18 ← in vertex form
.32 is the answer to this question
Answer:
Shannon
Step-by-step explanation:
Answer:
<h2>36°</h2>
Step-by-step explanation:
We know that angles BOC and AOB are complementary angles, that is, the sum 90°. Additionally, we know that
and
, which can be expressed as

Let's solve for 

Using this vale, we find the measure of angle AOB

Therefore, the answer is 36°.
