Answer:
7. Approximately 402.7 inches or 2pi times 64
8. 31.83 To solve this you know 2pi r is an equation for the radius. 2πr=200 and r=200/2π=100/π= 31.83.
9. The one with pi in the equation because 3.14 is only a piece of pi but the symbol represents the whole number which goes on forever.
Step-by-step explanation:
Answer:
B: y = 2x² - 16x + 40
Step-by-step explanation:
You can find this simply by expanding the given function:
y = 2(x - 4)² + 8
y = 2(x² - 8x + 16) + 8
y = 2x² - 16x + 32 + 8
y = 2x² - 16x + 40
This is the concept of trigonometry, to get the horizontal length we use the formula:
cos θ=(Adjacent)/(hypotenuse)
θ=6°
adjacent=x
hypotenuse=170m
thus the value of x will be:
x/170=cos6
hence:
x=170 cos 6
x=169.06872 meters
Answer: 169.06872 m
its C the only one that makes a angle
