Answer:
Length of shadow (Base) = 8 ft
Step-by-step explanation:
Given:
Height of man (Perpendicular) = 6 ft
Length from head to shadow (Hypotenuse) = 10 ft
Find:
Length of shadow (Base)
Computation:
Base = √Hypotenuse² - Perpendicular²
Base = √10² - 6²
Length of shadow (Base) = 8 ft
Answer:
174.19 cm3 i am not sure though.

Answer:
Linked an image
Step-by-step explanation:
Okay, basically since it is y=2co3x you know that the amplitude is 2, so rather than going to +1 and -1, you now go to +2 and -2. Since it's cosine, you also know that you start at the maximum rather than the intercept, so the starting point is at (0,2).
I'm assuming that you need to graph 2 periods, and to find the periods you divide 2pi/b, so, in this case, 2pi/3
Then lastly you need to find the four points between 0 and 2pi/3, so you divide 2pi/3/4 to get 2pi/12=pi/6
If you have any other questions just comment and I'll respond when I see it.
First pair goes to f(x) = 20x
Next pair goes to f(x) = 10x + 20
Third pair goes to f(x) = 10x + 25
Last pair goes to f(x) = 20x + 10
Answer:
16
Step-by-step explanation:
x² + 8x = 4 ⇔ x² + 8x + 16 = 4 + 16 ⇔ x² + 2×4x + 4² = 20 ⇔ (x + 4)² = (2√5)²
Remark : (2√5)² = 20
