Answer:
Step-by-step explanation:
This is a composite function, in which we will first evaluate the s function at a value of 2, then we will use that value in the t function.
s(2) = 5(2)+ 5 so
s(2) = 15. Now we evaluate the t function at 15:
t(15) = 3(15) + 4 so
t(15) = 49
Answer:
The correct answer is 61.08 foot.
Step-by-step explanation:
Length of the string of the kite, Mr. Black is flying is 65 foot. Thus the length between the kite and Mr. Black is given by 65 foot.
Angle of elevation is 70°.
We need to calculate the height of the kite above Mr. Black's head. The height is given by finding the sine of the angle of elevation.
Let the height be x foot.
Thus sin 70° =
⇒ x = sin 70° × 65
⇒ x = 61.08
Thus the height of the kite above Mr. Black head is 61.08 foot.

Answer:
HI = 26
Step-by-step explanation:
To
calculate this, we use the principle of similar triangles
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
Thus, we have it that;
Let HI = x
x/x + 39 = 12/30
30(x) = 12(x + 39)
30x = 12x + 468
30x - 12x = 468
18x = 468
x = 468/18
x = 26
HI = 26
