Answer:
Range D = {-7, 1, 9, 17}
Step-by-step explanation:
f(x) = 4x + 9
4(-4) + 9 = -7
4(-2) + 9 = 1
4(0) + 9 = 9
4(2) + 9 = 17
Answer:
if I'm not mistaken it would be A, I'm not entirely too sure though
Answer:
7, 23
Step-by-step explanation:
R could lie either to the left of S or to the right of S on the number line
Therefore possible values for R are 15-8 = 7
and 15 + 8 = 23
Answer:
WV = 169.591 feet
Step-by-step explanation:
As VWX has ∠X equal to 90°, so that it is the right triangle.
In the right triangle, there is a formula as following:
sin <em>acute angel = opposite side/ hypotenuse side</em>
So that, in triangle VWX:
+) <em>sin ∠W = XV / WV </em>
as ∠W =20° and XV is equal to 58 feet, replace it into the formula above, we have:
sin ∠W = sin 20° = 58/ WV
=> WV = 58/ (sin 20°)
sin 20° ≈ 0.342
=> WV ≈ 58/ 0.342 = 169.591 feet
