A) Cait made two errors:
- a discount is a deduction so it should be subtracted from the 100% (1.00 - 0.15 = 0.85), not added to 100% (1.00 + 0.15 = 1.15).
- she paid 6% of the discounted amount, not 6% in addition to the discounted amount.
B) Original amount × Percent remaining after discount × percent paid
= (20)(0.85)(0.06)
= $1.02
Answer: The angle of elevation should be 38.9 degrees.
To find this answer, it is always best to draw a picture of the building. The point of the roof, will be directly over the middle of the cabin. Therefore, we could draw an altitude down from the top to the cabin and create a right triangle.
This would form a triangle with an adjacent side and hypotenuse with our needed angle.
We could write and solve the following cosine equation:
cos(x) = 21/27
x = 38.9
F(x) = 4 - 2x Domain = x = -4, 0, 5
f(x) = 4 - 2(-4) = 4 - (-8) = 12
f(x) = 4 - 2(0) = 4 - 0 = 4
f(x) = 4 - 2(5) = 4 - 10 = -6
f(x) = 12, 4, -6
The range is C.
Answer:
1
Step-by-step explanation:
y=mx+c
m is the gradient/slope
y=1x
hence m=1
