Answer:
B.
Step-by-step explanation:
Total surface area of the square pyramid
= 4 times the area of one triangle + Area of square
21 fence posts. i dont know how to draw a picture on this site, but you covert 16in to ft and then divide 32 by 1.5
first off, let's notice the parabola is a vertical one, therefore the squared variable is the x, and the parabola is opening upwards, meaning the coefficient of x² is positive.
let's notice the vertex, or U-turn, is at (-2, 2)
In 22, you're looking for the vertical height of the triangle. You're given the angle opposite the side you want to find (which I'll call
) and the length of the hypotenuse. This sets you up with the relation
In 23, you're given a similar situation, except now you're looking for the angle (I'll call it
) in the triangle opposite the side denoting the height of the airplane. So this time,
