Answer:
b/h
Step-by-step explanation:
remember SOH CAH TOA. Sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite/adjacent. So in this case use CAH for cos L. Adjacent to L is b, and the hypotenuse is h. Therefore the answer is b/h.
The question asks for sales tax rate. Sales tax is 39.90-38=1.90 and that's taxed onto the original $38 so 1.9/38=0.05
5% tax on the blazer
Step-by-step explanation:
S = ∫ 2π y ds
ds = √(1 + (dx/dy)²) dy
ds = √(1 + (8y)²) dy
ds = √(1 + 64y²) dy
S = ∫₁² 2π y √(1 + 64y²) dy
S = π/64 ∫₁² 128y √(1 + 64y²) dy
S = π/64 [⅔ (1 + 64y²)^(³/₂)] |₁²
S = π/96 (1 + 64y²)^(³/₂) |₁²
S = π/96 (1 + 256)^(³/₂) − π/96 (1 + 64)^(³/₂)
S = π/96 (257√257) − π/96 (65√65)
S = π/96 (257√257 − 65√65)
2 times as if it tried to go in once more it would collide and severely injure itself
Answer:
7x^2 + 2x - 5
Step-by-step explanation:
(4x^2 + x - 9) + (3x^2 + x + 4)
7x^2 + 2x - 5
Pretty simple, just add 4 and 3, then x (or 1) and x, lastly -9 and 4. Then you get your final equation.
