Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x
Consider the left side
[tex]\frac{cosA}{1-sinA}[/tex] ← multiply numerator/denominator by (1 + sinA)
= [tex]\frac{cosA(1+sinA)}{(1-sinA)(1+sinA)}[/tex] ← expand denominator using FOIL
= [tex]\frac{cosA(1+sinA)}{1-sin^2A}[/tex]
= [tex]\frac{cosA(1+sinA)}{cos^2A}[/tex] ← cancel cosA on numerator/ denominator
= [tex]\frac{1+sinA}{cosA}[/tex]
= right side , thus proven

Answer: 12. 5/20
13. 12/16
14. 35/15
15. 20/36
18.45/24
Step-by-step explanation: 12. 4x5=20 so 1x5=5 so its 5/20
13. 3x4=12 so 4x4=16 so its 12/16
14. 7x5= 35 so 3x5=15 so its 35/15
15. 9x4=36 so 5x4=20 so its 20/36
18. 15x3=45 so 8x3=24 so its 45/24

Answer:
F; A translation of 6 up and 4 left and a reflection across the x-axis
Step-by-step explanation:
Here, we want to perform the translation that would move S to S’
to do this, we can have a subtraction
For 1 to move to -3 on the x-axis;
it means there is a leftward shift of upto 4 units
For -8 to turn to 2;
this is positive; there is a vertical upward translation of upto 10 units on the y-axis
This option is not directly available; thus we have to factor the reflection
if we reflect on the x-axis, the y-axis value becomes negated; if we reflect on the y-axis, the x-value becomes negated
The correct answer is thus;
A translation of 6 up and 4 left, followed by a reflection across the x-axis

if p(x)=2x+3y Q(x) = x + 2 what is
p(x) + Q (x)
Answer:
p(x)+Q(x)=(2x+3y)+(x+2)=2x+3y+x+2= 3x+3y+2
3x+3y+2 is the right answer.
Answer:
if p(x)=2x+3y Q(x) = x + 2 what is
p(x) + Q (x)=2x+3y+x+2=3x+3y+2

Jerry thinks that x < 4 is a solution to the following inequality: 2x + 10 < 4x - 20
Is Jerry right? Justify your response.
plss guys help me i only have 6 minutes left
Answer:
x>15
Step-by-step explanation:
Given the inequality: 2x + 10 < 4x - 20
Collect like terms

What is the purpose of parentheses in a two-step problem?
Parentheses tell you to multiply first.
Parentheses tell you to do the operation with the largest numbers.
Parentheses tell you to add first.
Parentheses tell you what operation to do first.
Answer:
The Parenthesis tells you what operation to do first.
Step-by-step explanation:
Why? Because you have to get rid of the Parenthesis before getting rid of anything else in the problem.
Use the data to complete the line plot then answer the question a clerk in a health food store makes bags of trail mix the amount of trail mix in each bag is listed below
Answer:
The average amount of trail mix in each bag is [tex]\frac{1}{2}[/tex]lb
Step-by-step explanation:
First, we need to calculate the sum of all the trail mix
Sum of Trail Mix = [tex]\frac{1}{4}[/tex]lb +
Now count the numbers of trail mixes
Numbers of trail mixes = 12
Calculate the average amount of the trail mix using the following formula
Average Trail mix = Sum of Trail Mix / Numbers of trail mixes
Average Trail mix = 6 lb / 12
Average Trail mix = [tex]\frac{1}{2}[/tex]lb
