12) A radio transmission tower is 170 feet tall. How long should a guy wire be if it is to be attached 15 feet from the top and is to make an angle of 30° with the ground? Give your answer to the nearest tenth of a foot.
13) A building 230 feet tall casts a 100 foot long shadow. If a person looks down from the top of the building, what is the measure of the angle between the end of the shadow and the vertical side of the building (to the nearest degree)? (Assume the person's eyes are level with the top of the building.)
The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°
What is trigonometric ratio?
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
a) Let l represent the length of the guy wire.
sin(30) = (170 - 15) / l
l = 310 feet
b) Let Ф represent the angle, hence:
tanФ = 100/230
Ф = 23°
The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°

A square pyramid has a height of 6 units and a volume of 70 units. If a square prisn
has the same base area and volume as the square pyramid, what is its height?
O2 2 units
4 units
6 units
08 8 units
Answer:
6 units
Step-by-step explanation:
Volume of square pyramid is
1/3 * base area * height
For the first pyramid
70 = 1/3 * base * 6
base = 35
For the second pyramid
70 = 1/3 * 35 * h
h = 6
Mary, Kate and Amy have a total of $159. Mary has $11 more than Kate. Amy has twice as much money as Kate. a)Using a bar model, illustrate this scenario showing CLEARLY where the $11 and $159 go. b)Determine how much money each girl has.
Kate has $37, Mary has $48, and Amy has $74.
EquationsGiven that Mary, Kate and Amy have a total of $159, and Mary has $11 more than Kate, while Amy has twice as much money as Kate, to determine how much money each girl has, the following calculation must be performed:
M = K + 11A = 2KK = KK + 11 + 2K + K = 1594K = 159 - 11K = 148 / 4K = 37So Kate has $37, Mary has $48, and Amy has $74.

room that is 10 ft. 9in, by 15ft. 3 in.
a. What is the perimeter of the room?
B. How many 6in by 6in square tiles are required to cover the floor?
C. Calculate 10% of the answer from
Part b (this accounts for the overage due to grout and waste)
The perimeter of the room is 624 inches.
We need 657 tiles to cover the floor.
We need to add 66 extra tiles to account for the overage due to grout and waste.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
Length = 10 ft 9in
Width = 15ft 3 in
a.
Perimeter = 2 (Length + Width)
Length = 10 ft 9 in = (10 x 12) + 9 = 129 in.
Width = 15 ft. 3 in. = (15 x 12) + 3 = 183 in
Perimeter.
= 2(129 + 183)
= 624 in.
b.
Area = Length x Width
Area = 129 in. x 183 in
Area == 23,607 in²
Each tile covers an area of 6 in. x 6 in
Area of tiles = 36 in²
So,
The number of tiles required.
= Area ÷ Tile area
= 23,607 in² ÷ 36 in²
≈ 656.3 tiles.
c.
10% of 657
= 10/100 x 657
= 0.1 x 657
= 65.7
= 66
Thus,
The perimeter of the room is 624 inches.
We need 657 tiles to cover the floor.
We need to add 66 extra tiles to account for the overage due to grout and waste.

Solve for y. 2y - 5 = 5y - 11
Answer:
y = 2
Step-by-step explanation:
Given equation:
[tex]2y - 5 = 5y - 11[/tex]
Subtract 5y both sides:
[tex]\implies 2y - 5 = 5y - 11[/tex]
[tex]\implies 2y - 5 - 5y = 5y - 5y - 11[/tex]
[tex]\implies -3y - 5 = -11[/tex]
Add 5 both sides:
[tex]\implies -3y - 5 = -11[/tex]
[tex]\implies -3y - 5 + 5 = -11 + 5[/tex]
[tex]\implies -3y = -6[/tex]
Multiply -1 both sides:
[tex]\implies -3y = -6[/tex]
[tex]\implies \dfrac{-3y}{-1} = \dfrac{-6}{-1}[/tex]
[tex]\implies 3y = 6[/tex]
Divide 3 both sides:
[tex]\implies 3y = 6[/tex]
[tex]\implies \dfrac{3y}{3} = \dfrac{6}{3}[/tex]
[tex]\implies \boxed{y = 2}[/tex]

The value of (1/2)x⁴ - (1/4)x² when x = 2 is 7.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is (1/2)x⁴ - (1/4)x².
We have to calculate the value of the expression when x = 2.
Substitute x = 2 in the expression.
(1/2)x⁴ - (1/4)x² = (1/2) (2)⁴ - (1/4) (2)²
= (1/2) × 16 - (1/4) × 4
= 16/2 - 4/4
= 8 - 1
= 7
Hence the value of the expression when x = 2 is 7.

An ellipse has vertices along the major axis at (0,1) and (0,-9). The foci of the ellipse are located at (0,-1) and (0,-7). The equation of the ellipse is the form below. (y-k)^2/a^2 + (x-h)^2/b^2 = 1 Which is a correct value for one of the variables shown in the equation?
a = 10
b = 4
h = 3
k = 0
The equation of the ellipse in standard form with vertices along the major axis at (0, 1) and (0, -9) and the foci of the ellipse at (0, -1) and (0, -7) is (y+4)²/16 + x²/25 = 1.
How to derive an equation of the ellipse based on the information of the major axis and foci
The location of the center of the ellipse is the midpoint of the line segment between the ends of the major axis, that is:
(h, k) = 0.5 · (0, 1) + 0.5 · (0, -9)
(h, k) = (0, -4)
The length of the major semiaxis (b) is 5 and the distance between the center and any of the foci (c) is 3. Then, the length of the minor semiaxis is:
[tex]a = \sqrt{b^{2}-c^{2}}[/tex] (1)
a = 4
Lastly, we substitute all the variables and conclude that the equation of the ellipse is (y+4)²/16 + x²/25 = 1. [tex]\blacksquare[/tex]

Arrange the three side
lengths in increasing
order.
Answer:
a < c < b
Step-by-step explanation:
The sum of the interior angles of a triangle is 180°
Therefore, the measure of the missing angle (opposite side c) is:
180° - 69° - 54° = 57°
Relationship between sides and interior angles of any triangle:
The shortest side is always opposite the smallest angleThe longest side is always opposite the largest angleTherefore, from inspection of the triangle:
a is opposite the smaller angle of 54°c is opposite the angle of 57°b is opposite the largest angle of 69°So the side lengths in increasing order are:
a < c < b
Rest angle:-
180-(69+54)180-12357Note that smaller side has smaller opposite angle

(a). sin2x + sinx = 0 ( 0 ≤ x ≤ 2π )
sin2x = 2sinx(cosx)
2 ( sin x )( cos x ) + sin x = 0
sin x ( 2 cos x + 1 ) = 0
sin x = 0 ⇒ x = 0 , [tex]\pi[/tex] , [tex]2\pi[/tex]
2 cos x = - 1
cos x = [tex]-\frac{1}{2}[/tex] ⇒ x = [tex]\frac{2\pi }{3}[/tex] , [tex]\frac{4\pi }{3}[/tex]
x ∈ { 0 , [tex]\frac{2\pi }{3}[/tex] , [tex]\pi[/tex] , [tex]\frac{4\pi }{3}[/tex] , [tex]2\pi[/tex] }
(b). sin 2x - 2 cos x = 0 ( 0 ≤ x ≤ 2π )
2 cos x ( sin x - 1 ) = 0
cos x = 0 ⇒ x = [tex]\frac{\pi }{2}[/tex] , [tex]\frac{3\pi }{2}[/tex]
sin x = 1 ⇒ x = [tex]\frac{\pi }{2}[/tex] , [tex]\frac{3\pi }{2}[/tex]
x ∈ { [tex]\frac{\pi }{2}[/tex] , [tex]\frac{3\pi }{2}[/tex] }
