Answer:
The height of the light pole to the nearest foot is approximately 50 feet
Step-by-step explanation:
The parameters given in the question are;
The length of the cable = 63 feet
The angle of elevation of the cable to the top of the light pole = 52°
With the assumption that the light pole is perpendicular to the ground, the figure formed by the light pole, the distance of the of the cable from the base of the light pole and the length of the cable form a right triangle
The question can be answered by using trigonometric relations for the sine of the given angle as follows;
[tex]sin ( \theta) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
The opposite leg length of the formed right triangle = The height of the light pole
The hypotenuse length = The length of the cable = 63 feet
The angle, θ = The angle of elevation = 52°
Plugging in the values, gives;
[tex]sin (52 ^ {\circ}) = \dfrac{The \ height \ of \ the \ light \ pole }{63 \ feet}[/tex]
∴ The height of the light pole = 63 feet × sin(52°) ≈ 49.645 feet
The height of the light pole to the nearest foot ≈ 50 feet.

Lilly wants to determine the association between her deposits and her savings account balance. She modeled the equation y = 75x + 100
for the line of best fit. The independent variable, x, is deposits and the dependent variable, y, is account balance. What does the y
intercept mean in this context?
A)
The starting savings account balance is $75.
B)
The starting savings account balance is $100.
The account balance increases by an additional $75 for
each deposit.
D)
The account balance increases by an additional $100 for
each deposit.
Answer:
D) The account balance increases by an additional $100 for each deposit
Step-by-step explanation:
The y intercept will always be the number being added or subtracted from the independent variable.
The y intercept of y = 75x + 100 is 100, it means that the starting savings account balance is $100.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where m is the rate of change and b is the y intercept.
Given the equation:
y = 75x + 100
The y intercept is 100, it means that the starting savings account balance is $100.

Answer:
6v^2 - 35v + 6wv - 42w - 49
Step-by-step explanation:
Use distributive property
First multiply 6v to each term within the second set of parentheses
6v^2 - 42v
Now multiply 6w to each term within the second set of parentheses
6wv - 42w
Next multiply 7 to each term within the second set of parentheses
7v - 49
Add all of these numbers together
6v^2 - 42v + 6wv - 42w + 7v - 49
Combine like terms
6v^2 - 35v + 6wv - 42w - 49
No more like terms so the expression is simplified
80x49=?

The area of the triangle below is 5/12 square feet. What is the length of the base? Express your answer as a fraction in simplest form.
1/2 ft is the height
Answer:
5/4 ft
Step-by-step explanation:
Given data
Area= 5/12 square feet
Height= 1/2 ft
Base=????
We know that the area of a triangle is given as
Area= (1/2)B*H
substitute
5/12= 1/2* B* 1/2
5/12= B/4
cross multiply
12B= 20
B= 20/12
B= 5/3
Hence the base is 5/4 ft

Step-by-step explanation:
Rewrite y = x2 +6x+ 10 in graphing (vertex) form by completing the square. State the VERTEX.
Answer:
The vertex of the graph is (-3,1)
Step-by-step explanation:
Here, we want to rewrite the given quadratic equation in the vertex form
We have the vertex form as;
y = a(x-h)^2 + k
where the vertex is (h,k)
Now, by completing the square, we have to divide the coefficient of x by 2, then square; after which we add to both sides; prior to this, we have to replace y by 0
Thus, we have it as follows;
x^2 + 6x + 10 = 0
x^2 + 6x + 10 + 3^2 = 3^2
x^2 + 6x + 19 = 9
x^2 + 6x + 9 = 9-10
(x + 3)^2 = -1
(x + 3)^2 + 1 = 0
So we have the vertex as ;
(h,k) = (-3,1)
In parallelogram ABCD with diagonal AC and BD,If angle 1 =50 angleDCB =115 find angle 2
Answer:
180- 115= 50+∠2
65-50= ∠2
15°=∠2
Step-by-step explanation:
Answer:
d. 15 degrees
Step-by-step explanation:
You're basically trying to find angle DBC. Adding 115 and 50 will give you 165. This means that angle DBC must be 15, as the angles have to add up to 180. Angle 2 and angle DBC are equal, so angle 2 is 15 degrees.

Explain how we know that the sine of 270 degrees is -1. State one other value of θ such that sinθ=1.
Solution :
Trigonometry is that branch of mathematics which is used to study the relationship between the angles and the lengths of the sides of a triangle.
We known that the co-ordinate of a point on the circumference of a circle making an angle θ with the horizontal having a unit radius is given by :
(1 cos θ, 1 sin θ).
And for any angle made by sin θ on the x - axis is 0 and on the y -axis is 1 or -1 depending on the quadrant.
Since, angle 270 degree falls on the 3rd quadrant, therefore, the value of the co-ordinates of the point is (cos θ, sin θ) = (0,-1).
So the value of sin 270° = -1.
One other example of sin θ = 1 is 90° as 90 degree falls in the first quadrant.
Jeremy measured the room to be 10 feet long and 4.5 feet wide. He plans to purchase carpet for the entire room. The carpet cost $15 per square meter. What will be the total cost of the new carpet to the nearest cent?
Answer:
$205.73
Step-by-step explanation:
First we find the square area,
multiply 10 by 4.5 and we get 45
we convert feet to meters by dividing it by 3.281
45/3.281=13.71533
we the multiply 13.71533 by 15 to get the total price
we get 205.72996 and round it to 205.72
