Answer:
discount = 25%
Step-by-step explanation:
discount is calculated as [tex]\frac{reduction}{original}[/tex] × 100%
reduction = 2800 - 2100 = 700
discount = [tex]\frac{700}{2800}[/tex] × 100% = 0.25 × 100% = 25%

Which function defines ?
A.
B.

Step-by-step explanation:
(g - f)(x)
= g(x) - f(x)
= log(x - 3) + 6 - ([tex]\sqrt[3]{12x+1}[/tex] + 4)
= log(x - 3) + 6 - [tex]\sqrt[3]{12x+1}[/tex] - 4 ← collect like terms

What is function?" Function is defined as the relation between the given variables is such that every input has exactly one output each."
According to the question,
Given functions are,
[tex]f(x) = \sqrt[3]{12x+1} +4\\\\g(x) = log(x-3) +6[/tex]
Substitute the value in the function (g -f)x we get,
[tex](g-f)x = g(x) -f(x)[/tex]
[tex]= log(x-3) + 6 -( \sqrt[3]{12x+1} +4)\\\\= log(x-3) + 6 -\sqrt[3]{12x+1} -4\\\\= log(x-3) -\sqrt[3]{12x+1} +2[/tex]
Hence, Option(B) is the correct answer.

Answer:
MNO ~ OPQ by AAA (Angle angle angle)
Step-by-step explanation:
1. angle POQ is equal to angle NOM because they are both vertical angles
2. angle OPQ and angle OMN are equal because parallel lines cut by a transversal form congruent alternate interior angles.
3. angle PQO and angle ONM are equal becase of the same reason as reason 2 (parallel lines cut by a transversal form congruent alternate interior angles. )

Answer:
The value of the expression for x=3 is 51
Step-by-step explanation:
Evaluating expressions
To evaluate a given expression, we simply substitute the value of the variables and complete the operations.
The expression to evaluate is:
P=3(2+5x)
We will evaluate for x=3:
P=3(2+5*3)
The product must be done first:
P=3(2+15)=3*17=51

Use the diagram to answer the following questions
please help : Five baskets contain a total of 120 apples. The first and second baskets have a combined total of 62 apples. The second and third baskets have a combined total of 53 apples, the third and fourth baskets have a combined total of 45 apples, and the fourth and fifth baskets have a combined total of 42 apples. How many apples are in each basket?
The number of apple in each basket is as follows:
First basket = 25 apples
Second basket = 37 apples
Third basket = 16 apples
Fourth basket = 29 apples
Fifth basket = 13 apples
Total apples in the five baskettotal apples = 120
let
the number of apples in the first basket = a
the number of apples in the second basket = b
the number of apples in the third basket = c
the number of apples in the fourth basket = d
the number of apples in the fifth basket = e
Therefore,
a + b = 62
b + c = 53
c + d = 45
d + e = 42
a + b + c + d + e = 120
62 + 45 + e = 120
e = 120 - 62 - 45
e = 13
d = 42 - 13
d = 29
c = 45 - 29
c = 16
b = 53 - 16
b = 37
a = 62 - 37
a = 25
Therefore,
the number of apples in the first basket = 25
the number of apples in the second basket = 37
the number of apples in the third basket = 16
the number of apples in the fourth basket = 29
the number of apples in the fifth basket = 13

Lina has 12 coins in her purse. D of them are dimes and the rest are quarters.
How many quarters does Lina have?
How much money does Lina have in quarters?
Answer:
she has 12 - D quarters.
She has 24 (12-D) cents in quarters
Step-by-step explanation:
You know that the number of coins, and you know the number of dimes - even if the amount is a variable - you can find the amount of quarters with an equation.
If you knew that Lina had 6 dimes instead of D, you would say 12 - 6 and get the number of quarters. You can do the same thing here.
and If you know Lina has 6 quarters, you could find the amount of money in cents by multiplying 6 by 25. You can do that here too, but with variables and an equation.
Answer:
she has 12 - D quarters.

Answer: see proof below
Step-by-step explanation:
Use the Cofunction Identity: sin (90 - A) = cos (A)
Use the Double Angle Identity: sin(2A) = 2 sinA cosA
Use the Triple Angle Identity: cos (3A) = 4cos³A - 3cosA
Use the Zero Product Property: If a · b = 0, then a = 0 or b = 0
Use Pythagorean Identity: cos²A + sin²A = 1 → cos²A = 1 - sin²A
Use Quadratic Formula: [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Proof LHS → RHS:
Assumption: Let A = 18°
Multiplication: then 5A = 5(18°)
→ 5A = 90°
Expand: 2A + 3A = 90°
→ 2A = 90° - 3A
Apply sin: sin (2A) = sin (90° - 3A)
Cofunction: sin (2A) = cos (3A)
Double Angle: 2 sinA cos A = cos (3A)
Triple Angle: 2 sin A cos A = 4cos³A - 3cos A
→ -4cos³A + 3cos A + 2sinA cos A = 0
Factor: cos A(-4cos² A + 3 + 2sin A) = 0
Zero Product Property: cos A = 0 or -4cos² A + 3 + 2sin A = 0
↓
Disregard (since cos A ≠ 0)
Pythagorean: -4cos² A + 3 + 2sin A = 0
→ -4(1 - sin² A) + 3 + 2sin A = 0
→ -4 + 4sin² A + 3 + 2sin A = 0
Simplify: 4sin² A + 2sin A - 1 = 0
a=4 b=2 c= -1
[tex]\text{Quadratic Formula:}\qquad \sin A=\dfrac{-(2)\pm \sqrt{2^2-4(4)(-1)}}{2(4)}[/tex]
