<span>thats the answer
x2 - 8x - 15
hope it helps

Answer:I believe it is C
Step-by-step explanation:
31) there are 12. The distance between them is 10-4=6. This is halfway around so there are 12 (think of a clock face, 4 is opposite 10 and there are 12 numbers.)
Answer:
1.
C. Point F
2.
B. Point B
Step-by-step explanation:
Hope this helped :) have a good day or night!!!
(A) Find the value of x. Round to the nearest tenth of a degree<span>
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft
In order to get the angle formed between the ground and the foot of the plank,
cos (theta) = ground / plank
cos (theta) = 9 / 41
</span><span>cos (theta) = 0.21951...
</span>theta = cos^-1(<span>0.21951...)
</span><span>theta = 77.3 degrees
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
</span><span>Height = square root (1600)
</span><span>Height = 40
(A) 77.1 Degrees
(B) 40 feet</span>
