Answer:
It means to the power.
Example*
2^2 = 2 to the power of 2 = 4
Answer:
24 ft.
Step-by-step explanation:
Volume (V) equals the product of length (l), width (w), and height (h)
V = l × w × h
Plug in the measurement you have into the equation
11232 = 13 × w × 36
Multiply 13 and 36
11232 = 468 × w
Divide both sides by 468
24 = w
Answer:
Cliff is 45 m tall.
Step-by-step explanation:
Given:
Height of Sarah = 1.8 m
Angle of elevation = 60°
Angle of elevation 50 m back = 30°
As shown in the figure we have two right angled triangles SPQ and SPR.
Let the height of the cliff be
meters and
.
Using trigonometric ratios:
tan (Ф) = opposite/adjacent
In ΔSPQ. In ΔSPR.

Answer:
1
Step-by-step explanation:
The average rate of change is measured as
in the closed interval [ a, b ]
here [ a, b ] = [ - 5, 5 ]
f(b) = f(5) = - 5² + 5 + 3 = - 25 + 8 = - 17
f(a) = f(- 5) = -(- 5)² - 5 + 3 = - 25 - 2 = - 27
Hence
average rate of change =
=
= 1
