If Ben is standing 8 feet from the base of the pole, find the height of the telephone pole. Round your answer to nearest thousandths of a foot.
Answer: The height of the telephone pole = $15.046
Step-by-step explanation:
Given: Angle of elevation= 62 degrees.
Distance of Ben from the base of the pole = 8 feet
According to trigonometry, we have
[tex]\tan x=\dfrac{\text{side opposite to x}}{\text{side adjacent to x}}[/tex]
i.e.
[tex]\tan 62^{\circ}=\dfrac{\text{ height of the telephone pole}}{8}\\\\(1.880726)=\dfrac{\text{ height of the telephone pole}}{8}\\\\\text{ Height of the telephone pole} = 8\times 1.880726\approx15.046[/tex]
Hence, The height of the telephone pole = $15.046

Step-by-step explanation:
find the function h(x)=f(x)+ g(x) if f(x) =2x^3+1 and g(x)=x^2- 4x+3
Answer:
h(x) = f(x) + g(x)
fill in the equations
h(x) = (2x^3 + 1) + (x^2 - 4x + 3)
h(x) = 2x^3 + 1 + x^2 - 4x + 3
combine like terms
h(x) = 2x^3 + x^2 - 4x + 4

The diameter of a circle is 4 cm. Find its area in terms of \piπ.
Answer:
Area of circle = 4π.
Step-by-step explanation:
Given the following data;
Diameter = 4cm
Pie = π.
To find the area of the circle;
Radius = diameter/2
Radius = 4/2
Radius = 2cm
Area of a circle = πr²
Substituting into the equation, we have;
Area of circle = π*2²
Area of circle = 4π.

What is 7 1/5 written as a percent
Answer:
720%
Step-by-step explanation:
Answer:
720 %
Step-by-step explanation:
Method 1
If 1 is equal to 100 percent, then 7 would be 700 percent. 1/5 is equal to 20 percent. If you add 700 % and 20 % you will get 720 %
Method 2
7 1/5 is equal to
7/1 × 5/5 + 1/ 5 = 35/5 + 1/5 = 36/5
We know that 36/5 is the same as 36 ÷ 5
36 divided by 5 gives us 7.2
Convert the decimal to a percent:
7.2 × 100 = 720%
Hope this helps :)

Step-by-step explanation:
Areesh is trying to build a box fort. He has 8 feet of duct tape.
The instructions are to use 22.5 inches of the tape to secure the roof of the box fort. Then, the remaining
tape should be cut into 5-inch sections to be used on the walls of the box fort. Areesh will use all of the
duct tape as instructed.
Determine the number of 5-inch sections of tape Areesh can cut.
Answer:
The number of 5-inch cuts if duct tape remainding is 14.
Step-by-step explanation:
1. 96 - 22.5 = 73.5
2. 73.5/5 = 14.7
3. .7 isnt a full piece of tape, so he has 14 5inch tapes

The product of two positive consecutive odd integers is 2703. What are the positive numbers?
Answer:
The positive numbers are 51 and 53
Step-by-step explanation:
Let first odd integer be x and another odd integer is (x+2).
According to the given condition,
The product of two positive consecutive odd integers is 2703 i.e.
x(x+2) = 2703
[tex]x^2+2x-2703=0[/tex]
It is a quadratic equation. It can be solved as follows :
x = 51 and x = -53
Neglecting negative sign,
The first number = 51
Another number =(51+2) = 53
Hence, the positive numbers are 51 and 53.

Answer:
y = 15x + 20 or 15x - y + 20 = 0
x = 11
Step-by-step explanation:
Line is passing through the points (0, 20) & (2, 50)
Slope of line = (50 - 20)/(2 - 0) = 30/2 = 15
Equation of line
y - 20 = 15(x - 0)
y - 20 = 15x
y = 15x + 20 or 15x - y + 20 = 0
Plug y = 185 in above equation, we find:
185 = 15x + 20
185 - 20 = 15x
165 = 15x
x = 165/15
x = 11
find the next four terms in a number pattern that follows the rule. start with the number 10. 10, 16, 22, 28, 34 Is 16, 22, 28, and 34 the answer?
Answer:
40, 46, 52, 58
Step-by-step explanation:
To find the next four terms, we have to find the pattern of the given terms.
We start at 10 and then go to 16.
Let's try adding 6 to each term and see what we get.
10 + 6 = 16
16 + 6 = 22
22 + 6 = 28
28 + 6 = 34
Looks like it matches the given terms.
To find the next four terms, we just have to keep adding 6 to each term.
34 + 6 = 40
40 + 6 = 46
46 + 6 = 52
52 + 6 = 58
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Calculate the area of the trapezoid, which is not drawn to scale.
Answer:
38 in
Step-by-step explanation:
Ok, so the bottom part is a rectangle and the top part is a triangle. We’re gonna split those into two different shapes.
8 * 4 = 32, this is the area of the bottom rectangle.
To get the side length of the top triangle, we have to subtract 8 from 11.
11 - 8 = 3
(3 * 4)/2 = 6, this is the area of the top triangle.
Add the two areas, 32 + 6 = 38
And that’s it, maybe, I think.
