The answer is 4 feet.
Draw a line segment from D perpendicular to AC and intersect AC at F.
triangle ADF is a right triangle, with angle AFD=90, Angle DAF=half of BAC=30
in a 30-60-90 triangle, the shortest side is half of the hypotenuse. the hypotenuse AD=8, so DF=4
Draw a line segment perpendicular from D to AB and intercept AB at E.
DE is also 4 feet, same as above.
Answer: This is <u>not</u> a function
Why not?
The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.
Put another way: we cannot have x repeating any values if we want a function.
Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).
The area of a triangle is 1/2 (base) (height) so the correct answer is B.
Answer:
-2(1.5h + 5) - 4(-0.5 + 3h) = -15h-8
Step-by-step explanation:
-2(1.5h + 5) - 4(-0.5 + 3h)
-2*(1.5h)+(-2*5)-(4*-0.5)-4(3h)
-3h-10-(-2)-12h
-3h-12h-10+2
-15h-8
