Answer:
10472. 4 ft
Step-by-step explanation:
Let the height of the plane above the helicopter be "h"
We have a right triangle where the side opposite the 71 degree angle = h and the side adjacent to this angle = 3055
So we can use the tangent here
tan (71) = h / 3055 multiply both sides by 3055
3055 * tan (71) = h ≈ 8872.4 ft
So.......the total altitude of the plane is
1600 + 8872.4 =
10472. 4 ft
Answer:
Step-by-step explanation:
Pythagorean Theorem: In the right triangle the square of longer side is equal to the sum of the squares of other sides.
Answer:
300%
Step-by-step explanation:
S = ab
S1 = 2a × 2b
S1 = 4ab
S1 = 400%ab
=>The area is increased by 300%
If you observe the graphs, you can see that the graph of G(x) is obtained by moving F(x) 1 unit to left.
Moving one unit to left is equivalent to adding 1 to x in the base of the expression in given case.
So,
G(x) = F(x+1)
G(x) = (x+1)²
Thus the correct answer is option D
Answer:
45 members are in the choir.
Step-by-step explanation:
Set up an equation:
Variable x = boys
3/6 = x/30
Cross multiply:
3 × 30 = 6 × x
90 = 6x
Divide both sides by 6:
15 = x
There are 15 boys.
To find the number of members in the choir, add the number of boys and girls:
30 + 15 = 45
