Answer:
D(x=1).
Step-by-step explanation:
2(5x+8)=6x+20
10x+16=6x+20
10-6x+16=6x-6x+20
4x+16=20
4x+16-16=20-16
4x=4
4x/4=4/4
x=1
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°.
The other two angles are 40° and 100°.
The defect rate of a company is equal to the probability of a randomly selected sensor from that company being defective.
Breaker's has a 4% defect rate, so the probability that a Breaker's sensor being defective is 4%, or 0.04.
The answer is A) 0.04
Answer: f(-2) = 11
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given information</u>
f (-2) or x = -2
<u>Given function</u>
f(x) = -x² - 10x - 13
<u>Substitute values into the function</u>
f(-2) = -(-2)² - 10 (-2) - 13
<u>Simplify exponents</u>
f(-2) = -(4) - 10 (-2) - 13
<u>Simplify by multiplication</u>
f(-2) = 4 + 20 - 13
<u>Simplify by addition/subtraction</u>
f(-2) = 24 - 13
f(-2) =
