Note (For 1st Question) :
• Figure is provided in the Attachment[tex].[/tex]
Answer:
1)
y = 45° (converse of alternate interior angle theorem)
z = 45° (alternate interior angle theorem)
k = 135° (exterior angle theorem)
2)
Cos θ + Sin θ = √2 Cos θ
(Cos θ + Sin θ)² = (√2 Cos θ)²
(Exponential property of equality)
Cos² θ + Sin² θ + 2 (Cos θ • Sin θ) = (√2 Cos θ)²
(Distributive property)
1 + 2(Cos θ • Sin θ) = (√2 Cos θ)²
(Definition of the pythagorean identity).
This identity is true because, if a² + b² = c². The triangle must be a right triangle, and a right triangle always has a 90° angle tangent to the triangle, and the tangent of 90° is 1, cos applied to the adjacent over hypotenuse, and sin applies to the opposite over hypotenuse, so this identity must work).
1 + 2(Cos θ • Sin θ) = 2 Cos² θ
(definition of an exponent)
1 + 2(Cos θ • Sin θ) – 1 = 2 Cos² θ – 1
(subtraction property of equality)
2(Cos θ • Sin θ) = 2 Cos² θ – 1
2(Sin θ • Cos θ) = 2 Cos² θ – 1
(Associative property of multiplication ; the input for both functions are θ so this rule works, this is an exception)
Sin (2x) = 2 Cos² θ – 1
(double angled identity of 2 sine and cos)
Truetone Music company sold 192,000 alternative music downloads. This represents 64% of their total sales. How
many total downloads did Truetone selt?
Answer:
The total downloads is 300000
Step-by-step explanation:
Given
Represent the total downloads with D.
[tex]\% = 64\%[/tex]
[tex]Sales = 192000[/tex]
Required
Determine the value of D
We understand that 64% of D = sales.
In other words;
[tex]64\% * D = 192000.[/tex]
Convert % to decimal
[tex]0.64 * D = 192000.[/tex]
Make D the subject
[tex]D = 192000/0.64[/tex]
[tex]D = 300000[/tex]
Hence, the total downloads is 300000

find the slope of the line that contains the points (-6, 4) and (2, -8)
Answer:
slope = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 4) and (x₂, y₂ ) = (2, - 8)
m = [tex]\frac{-8-4}{2+6}[/tex] = [tex]\frac{-12}{8}[/tex] = - [tex]\frac{3}{2}[/tex]

If the diameter of the circle is 24 cm, find its area correct to one decimal place.
A= ______ cm2
Answer:
A=pi times radius squared
24/2= 12 is the radius (since it's half of diameter)
A=pi times 12 squared
12 squared is 12 times 12 which is 144
A=pi times 144
A=452.389342
Rounded to 452.4

HELp ASAP!!!! Natalie works in a toy shop and earns $43 per day. She earns an extra $3 for each toy she sells. If Natalie wants to earn at least $70 per day, which inequality shows the minimum number of toys, n, that she should sell? (5 points)
a
43 + 3n ≥ 70, so n ≥ 9
b
43 + 3n ≤ 70, so n ≤ 9
c
43 + 3n ≥ 70, so n ≥ 24
d
43 + 3n ≤ 70, so n ≤ 24

What is the point-slope form of the line with slope 25 that passes through the point (−4, −7)?
y−7=2/5(x−4)
y+7=2/5(x+4)
y+4=2/5(x+7)
y−4=2/5(x−7)
Answer:
y + 7 = 2/5 (x + 4)
Step-by-step explanation:
(I hope 25 is 2/5)
The formula is y - y1 = m (x - x1), so you put the variables in to y1 and x1 plus add the slope in as m, and there you are! Point slope form. (you also have to flip the signs when putting them in, causing -4 and -7 to become 4 and 7)
Hope this helps!

What is the slope of the graph of f(x) = 12x - 19?
Answer:m=12
Step-by-step explanation:
The equation is written in slope intercept form which is y=mx+b
Where m= slope and b=constant number so the above equation y=12x-9
M=12 slope of the equation
Answer:
1. The slope is 12
2. (6 - 2)/(12+4)= 4/16= 1/4
y - 2 = 1/4(x + 4)
y - 2 = 1/4x + 1
y = 1/4x + 3
Above Is Step-By-Step

A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 2900 seats. The students filled 986 of the seats in the theater. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answer:
34%
Step-by-step explanation:
To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.
[tex] \dfrac{986}{2900} \times 100\% = 0.34 \times 100\% = 34\% [/tex]
Answer:
34%
Step-by-step explanation:
986/2900 x 100 = 34%
