Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
cosec x = [tex]\frac{1}{sinx}[/tex] , cot x = [tex]\frac{cosx}{sinx}[/tex]
Consider the left side
[tex]\frac{(1+cosA)^2-(1-cosA)^2}{sin^2A}[/tex] ← expand and simplify numerator
= [tex]\frac{1+2cosA+cos^2A-(1-2cosA+cos^2A}{sin^2A}[/tex]
= [tex]\frac{1+2cosA+cos^2A-1+2cosA-cos^2A}{sin^2A}[/tex]
= [tex]\frac{4cosA}{sin^2A}[/tex]
= 4 × [tex]\frac{1}{sinA}[/tex] × [tex]\frac{cosA}{sinA}[/tex]
= 4cosecAcotA
= right side, thus proven

Find the value of f(-2)
Answer:
y = 3.5
Step-by-step explanation:
If you look at the x axis, you know x = -2 so you want to know y.
Use the graph to determine which statement describes f(x)
O A. f(x) does not have an inverse function, because its graph fails the
horizontal line test.
O B. f(x) has an inverse function, because its graph passes the
horizontal line test.
C. f(x) has an inverse function, because its graph passes the vertical
line test.
D. f(x) does not have an inverse function, because its graph fails the
vertical line test.
Answer:
f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A
Step-by-step explanation:
The vertical line test is used to show that the graph represents a
function or not
If the vertical line crosses the graph in more than one point, then the graph does not represent a functionIf the vertical line crosses the graph in only one point in different positions, then the graph represents a functionThe horizontal line test is used to show that the function has an
inverse or not
If the horizontal line crosses the graph of a function in more than one point, then the function has no inverseIf the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverseLet us look at the given graph
→ The graph represents a parabola, which represents the function f(x)
∵ Any horizontal line drawn will cross the graph in more than one point
∴ f(x) has no inverse
∴ f(x) does not have an inverse function, because its graph fails the
horizontal line test.
Twice a number y is no more than 12.

Helps me solve this problem please
Answer: 1, 3, 5, 6
Step-by-step explanation: There cannot be the same x value for more than 1 y value.
Find the inverse function of
y =x-5/6
[tex]f(x) = y = x - \frac{5}{6} \\ [/tex]
Subtract the sides of the equation plus 5/6
[tex]y + \frac{5}{6} = x \\ [/tex]
So ;
[tex] {f}^{ - 1}(x) = x + \frac{5}{6} \\ [/tex]

if you add a decimal ur answer is going to have a decimal
in this case 7.2 the decimal is in the tenths place so the answer would be 0.9
!/8 pound of fertilizer covers 25 square feet of ground, how much fertilizer, in pounds, is needed to cover 1 square foot ground?
Answer:
1/200 poundsStep-by-step explanation:
Given ratio
1/8 pound ⇔ 25 square feetTo find
x ⇔ 1 square footDivide both sides by 25
1/8÷25 pounds ⇔ 25÷25 square feet1/200 pounds ⇔ 1 square foot

7. Mark needs to move to a new apartment and is trying to find the most affordable moving truck. He will only need to truck for one day. After checking the U-Haul website, he finds that he can rent a 10 - ft truck for $20.95 a day plus $1.89 per mile. He then checks the Public Storage website and finds the charge to be $37.95 a
day plus $1.19 per mile for the same size truck. Determine the number of miles for which the cost to rent from either company would be the same. Round the answer to the nearest mile (5 points).
Answer:
24 miles
Step-by-step explanation:
Let the number of miles = x.
U-Haul:
1.89x + 20.95
Public Storage:
1.19x + 37.95
Set the costs equal and solve for the mileage, x.
1.89x + 20.95 = 1.19x + 37.95
0.7x = 17
x = 24.29
Answer: 24 miles

7x-130=110+9x. show with steps
Answer:
x=-120
Step-by-step explanation:
7x-130=110+9x
add 130 to both sides of the equation
7x-130+130=110+9x+130
Simplify
7x=9x+240
Subtract 9x from both sides
7x-9x=9x+240-9x
Simplify
-2x=240
divide both sides by -2
-2/-2=240/-2
simplify
x=-120

What is the angle pair relationship between angles 6 and 8?
Answer:
Two angles are complementary angles if the sum of their measures is 908.
Each angle is the complement of the other. Two angles are supplementary
angles if the sum of their measures is 1808. Each angle is the supplement of
the other.
Complementary angles and supplementary angles can be adjacent angles
or nonadjacent angles. Adjacent angles are two angles that share a common
vertex and side, but have no common interior points.
Step-by-step explanation:

determine if the equation is true x = 8
2x - 6 = 9
Answer:
False
Step-by-step explanation:
This is false because:
1) In order to solve this, we cam use the addition property of equality
2) First, you can add 6 to -6 and 9
New Equation: 2x = 15
3) Now divide 2 with 2 and 15
New Equation: x = 7.5
You can also check by inserting 8 into the equation.
2(8) - 6 = 9
16 - 6 = 9, this is not true.
Therefore, this statement is false. x = 7.5
Hope this helps! :D

why is math hard and important
Answer: Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. And then often end up with a weak structure that is doomed to collapse at some point.
Step-by-step explanation: math is important because some things in math are gonna be used in your daily life for example adding, subtracting, division Etc and also because Math helps us think analytically and have better reasoning abilities. Analytical thinking refers to the ability to think critically about the world around us. Analytical and reasoning skills are essential because they help us solve problems and look for solutions.
