Integers are like whole numbers, but they also include negative numbers ... but still no fractions allowed! So, integers can be negative {−1, −2,−3, −4, ... }, positive {1, 2, 3, 4, ... }, or zero {0}
Is B. A typo? Is it supposed to say -4? If so that’s the answer
Answer:
b
Step-by-step explanation:
Answer: 31.5ft²
Step-by-step explanation:
For any given triangle with two adjacent sides and an opposing angle, the area is determined by the formula:
1/2 * length A * length B * sin of angle of opposing side.
That is, if lenght A=x, length B= y and opposing angle is given as Z, then the area of such triangle becomes:
Area = 1/2 *x*y*sin Z
For the given triangle, x = 11feet, y = 10feet, Z=35°
Area= 1/2 * 11 * 10 * sin 35
Area = 31.5469ft²
Rounding up to the nearest tenth,
Area = 31.5ft²
That's a tough problem to type out! Thanks for sharing this image of the original expression.
What I'd do would be to write:
(fourth root of 9)^(x/2) = [ (9)^(1/4) ]^(x/2) = 9^(x/8)
so the second of the four possible answer choices seems correct.
