Answer:
25.61 feet
Step-by-step explanation:
First, we can draw a picture (see attached picture). With the wall representing the rightmost line, and the ground representing the bottom line, the ladder (the hypotenuse) forms a 80 degree angle with the ground and the wall and ground form a 90 degree angle.
Without solving for other angles, we know one angle and the hypotenuse, and want to find the opposite side of the angle.
One formula that encompasses this is sin(x) = opposite/hypotenuse, with x being 80 degrees and the hypotenuse being 26 feet. We thus have
sin(80°) = opposite / 26 feet
multiply both sides by 26 feet
sin(80°) * 26 feet = opposite
= 25.61 feet as the height of the wall the ladder reaches
Step-by-step explanation:
you have the formula and the numbers. just calculate !
cost of membership
y = 100 - 0.02x
a)
for x = 2600
y = 100 - 0.02×2600 = 100 - 52 = $48
b)
the reduction element of the cost of membership is the
"- 0.02x" part.
we want to refuse the membership costs by $41, so
0.02x = 41
x = 41/0.02 = $2,050
c)
the same as b)
just now the membership costs need to be reduced to 0.
so, that means we need to reduce by $100 !
0.02x = 100
x = 100/0.02 = $5,000
