Answer:
C
Step-by-step explanation:
First, let us try the first on:
sqrt (5^2+4^2)=sqrt 41 so it can't be A
Second one:
sqrt (6^2+7^2)=sqrt 85, no
Third one:
sqrt (8^2+6^2)=sqrt 100 = 10, so it is C
Answer:
<h2>The measure of angle B is 46.4°, approximately.</h2>
Step-by-step explanation:
We need to find the measure of angle B. Notice that it's a right triangle, where we already know the hypothenuse and the adjacent leg to the angle, that means we need to use the cosine trigonometric reason

Therefore, the measure of angle B is 46.4°, approximately.
Answer:
Area is 235
Step-by-step explanation:
Split the shape evenly so 11 x 14 and 9 x 9then multly and add
when slpitting up the number some times you have to add or subtract so to get 9 x 9 we just take 20 then take away 11 due to the line going through 20 and 20 - 11 = 9
9 x 9 = 81
11 x 14 = 154
81 + 154 = 235
or
Simular to the first one but the cutting line is different. this time the line cuts through 14
9 x 20 = 180
11 x 5 = 55
180 + 55 = 235
Answer:
A. y = 7(x + 1)²-3
Step-by-step explanation:
Parabola:


Putting into vertex form, remember that:

In this question:
, to put into this format:

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then
Vertex form:


So the correct answer is:
A. y = 7(x + 1)²-3
