Answer:
Height of the kite = 86.60 meter (Approx)
Step-by-step explanation:
The angle of elevation to see a kite from a stone lying to the ground is 60 degrees. If a thread is tied with a kite and a stone, then that thread is 100 meters long, find the height of the kite.
Given:
Length of thread = 100 meter
Angle of elevation = 60°
Find:
Height of the kite.
Computation:
Using trigonometry application:
Height of the kite / Length of thread = Sin 60°
Height of the kite / 100 = √3 / 2
Height of the kite = [√3 / 2]100
Height of the kite = 50√3
Height of the kite = 86.60 meter (Approx)

Answer:
Well, first of all, to find 80 - 103, you should subtract 103 from 80, get 23 as the sum, and add a negative since we're originally subtracting a smaller number from a bigger number.
-23
The answer is either A or C
Answer:
(a) -2 (multiplicity 2) and +2
(b) ±√2
Step-by-step explanation:
(a) Factor by grouping:
f(x) = (x^3 +2x^2) -(4x +8)
= x^2(x +2) -4(x +2) . . . . . remove the common factor from each group
= (x^2 -4)(x +2) . . . . . . . . .collect the factors
= (x -2)(x +2)(x +2) . . . . . . factor the difference of squares
Zeros are the values of x that make these factors be zero: {2, -2, -2}.
__
(b) g(x) = 0 = -x^2 +2
You can factor this as the difference of squares:
(√2 -x)(√2 +x) = 0
The zeros are the values of x that make these factors be zero: {√2, -√2}.
