Answer:
Step-by-step explanation:
Given data
Height of building= 30ft
We are told that after the ball landed it bounced 85% the height
let the new height be y
So the expression for the new height for x number of bounces is
-6(4x + 1) + 7x + 9(x - 3) = 4
-6(4x) - 6(1) + 7x + 9(x) - 9(3) = 4
-24x - 6 + 7x + 9x - 27 = 4
-24x + 7x + 9x - 6 + 27 = 4
-8x + 21 = 4
- 21 - 21
-8x = -17
-8 -8
x = 2.125
Answer:
the first one would be m<EOF+m<FOB=180°,
and the second one would be 76ft
Step-by-step explanation:
supplementary angle means the angle that would make it equal 180°. if m<EOF is an acute angle then the angle that is supplementary to EOF would be obtuse, so FOB.
then for the second question, the midpoint splits the angle in HALF, so that means in order to find RT you multiply 38×2.
The answer would be 1 out of twelve.
The center is (h,k), therefore the center of this circle is (3,7).
