Answer:
<h3>
m∠B = 26°</h3>
Step-by-step explanation:
∠A and ∠B being complementary means m∠A + m∠B = 90°
4x + 24 + 3x - 4 = 90
7x + 20 = 90
7x = 70
x = 10
m∠B = (3•10 - 4)° = 26°
Answer:
2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 0, 2 ], thus
f(b) = f(2) = -(2)² + 4)(2) + 2 = - 4 + 8 + 2 = 6
f(a) = f(0) = 2
average rate of change = 
= 
= 2
I believe that X would be -2.47619.
First you distribute the -1 in front of the parenthesis. Then distribute the 8 outside of the bracts. And finally just solve for X by combing like terms.
Answer:
2.5
Step-by-step explanation:
You can do this in an easier way than you may be thinking. You know that 1/000 is 1 mm, therefore to get 2,500, you multiply it by 2.5.
