Answer:
Height of flagpole = 571 ft
Step-by-step explanation:
Given:
Angle of elevation to the top of the flagpole is 55° .
Distance from the eyes to the base of flagpole = 400 ft.
To find the height of the flagpole.
Solution:
We can draw the situation as a right triangle as shown below.
In triangle ABC.
∠C= 55°
To find the length AB (height of the flagpole).
Applying trigonometric ratio :
Plugging in values.
Multiplying both sides by 400.
∴ 
Height of flagpole = 571 ft
Answer:

Step-by-step explanation:
The lower quartile 
is positioned at the left side of the box, that is
= - 4
The upper quartile 
is positioned at the right side of the box
= 6
y = mx + b
m = -3/4
y = (-3/4)x + b
Use the given point (4,-6) to find b:
-6 = (-3/4)(4) + b
-6 = -3 + b
b = -3
Final equation:
y = (-3/4)x - 3
Answer:
52
Step-by-step explanation:
g(-3) = 4(-3)^3 + 3 = -105
g(4) = 4(4)^3 + 3 = 259
AROC = 
= 
= 52
Answer:
(-4, -8)
Step-by-step explanation:
Use the substitution method. x = -4, so y = (1/2)x - 6 becomes:
y = (1/2)(-4) - 6, or y = -2 - 6, or y = -8.
The solution is (-4, -8).
