Answer:
L.S = R.S ⇒ Proved down
Step-by-step explanation:
Let us revise some rules in trigonometry
sin²α + cos²α = 1sin2α = 2 sin α cosαcscα = 1/sinαTo solve the question let us find the simplest form of the right side and the left side, then show that they are equal
∵ L.S = csc2α + 1
→ By using the 3rd rule above
∴ L.S = [tex]\frac{1}{sin2\alpha}[/tex] + 1
→ Change 1 to [tex]\frac{sin2\alpha}{sin2\alpha}[/tex]
∴ L.S = [tex]\frac{1}{sin2\alpha}[/tex] + [tex]\frac{sin2\alpha}{sin2\alpha}[/tex]
→ The denominators are equal, then add the numerators
∴ L.S = [tex]\frac{1+sin2\alpha}{sin2\alpha}[/tex]
∵ R. S = [tex]\frac{(sin\alpha+cos\alpha)^{2} }{sin2\alpha}[/tex]
∵ (sinα + cosα)² = sin²α + 2 sinα cosα + cos²α
∴ (sinα + cosα)² = sin²α + cos²α + 2 sinα cosα
→ By using the 1st rule above, equate sin²α + cos²α by 1
∴ (sinα + cosα)² = 1 + 2 sinα cosα
→ By using the 2nd rule above, equate 2 sinα cosα by sin2α
∴ (sinα + cosα)² = 1 + sin2α
→ Substitute it in the R.S above
∴ R. S = [tex]\frac{1+sin2\alpha}{sin2\alpha}[/tex]
∵ L.S = R.S
∴ csc 2α + 1 = [tex]\frac{(sin\alpha+cos\alpha)^{2} }{sin2\alpha}[/tex]

[tex]4x-38=53[/tex]
Solve for 'x'.
Answer:
x = 22.75
Step-by-step explanation:
Step 1: 4x - 38 = 53 <----- Here is the original problem.
Step 2: 4x - 38 + 38 = 53 + 38 <----- Add 38 to both sides.
Step 3: 4x = 91 <----- Simplify
Step 4: [tex]\frac{4x}{4} =[/tex] [tex]\frac{91}{4}[/tex] <----- Subtract both sides by 4.
x = 22.75

Suppose you have seven different sweatshirts, and wish to wear a different one each day of the week. in how many ways can this be done? a. 49 different ways b. 1 different way c. 210 different ways d. 5040 different ways
The total number of ways or permutations in which that can be done are: d. 5040 different ways
To solve this problem the formula and the permutation procedure we must use is:
nPr = n! / (n-r)!
Where:
nPr = permutationn = total number of objectsr = number of selected objects! = factorial of the numberInformation about the problem:
n = 7 (sweatshirts)r = 7 (days)7P7 =?Applying the permutation formula we have:
nPr = n! / (n-r)!
7P7 = 7! / (7-7)!
7P7 = 7! / 0!
7P7 = 7! / 1
7P7 = 7 * 6 * 5 * 4 * 3 * 2 * 1 / 1
7P7 = 5040

Hailey and her children went into a grocery store and she bought $10 worth of apples
and bananas. Each apple costs $1.25 and each banana costs $0,50. She bought a total
of 14 apples and bananas altogether. By following the steps below, determine the
number of apples, 2, and the number of bananas, y, that Hailey bought
Determine three ways to Have a total of 14 apples and bananas:
Cost of apples: $0.00
Cost of bananas: 50.00
Answer:
a = 4
b = 10
Step-by-step explanation:
Price of an apple $1.25
Price of a banana $0.5 0
The two equations:
10 = 1.25a + 0.5b
a + b = 14
solve for one variable
b = 14 - a
10 = 1.25a + 0.5(14-a)
10 = 1.25a+ 7 - 0.5a
10 = 0.75a + 7
0.75a = 3
a = 4
Then solve for the second
b = 14 - 4
b = 10

shortcut for finding the midpoint of a segment when one of its endpoints has coordinates (a, b) and the other endpoint is the origin.
Answer:
Hmm it has to be to divide the coordinates by 2
Step-by-step explanation:
Lets say you have (10, 8), and the other coordinate is (0, 0). If you divide 10 by 2 you get 5, and 8 by 2 you get 4, so what you get is (5, 4), which is the midpoint.
What is the answer??
Answer:
letter C is the right answer
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answer:
See attached graph for rise and run lines
Slope = -1
Step-by-step explanation:
The slope-intercept equation form of a line is given by
y = mx + b where m = slope and b the y-intercept
rise/run is the slope of the line and is given by Δy/Δx where Δy represents the change in y values and Δx the corresponding change in x values
To calculate slope, take any two points on the line, find the difference between their y values and divide them by the change in x values
Two points I have chosen are (-3, 0) and (0, -3)
[tex]\textsf{{Slope}}=\dfrac{\ensuremath{-3}-0}{0-(-3)}=\dfrac{-3}{3}=-1[/tex]
We can see from the graph that the y-intercept ie where the line crosses the y axis i s-3
So the equation of the line is y = -1x - 3

2(3w - 7) = 34 ( divide both sides by 2 )
3w - 7 = 17 ( add 7 to both sides )
3w = 24 ( divide both sides by 3 )
w = 8

The scale used to make a scale model of a car is 1:18. The length of the
model is 9 inches. How many feet long is the actual car?
The length of actual car is 13.5 feet
We are given the ratio, which will be interpreted as 1 inch of model will be equal to 18 inch of the real car.
So, the formula relating the scale length and actual length will be as follows -
Scale = Real
Model length at scale/Actual length at scale = Model length in real/Actual length in real
Keep the values in formula to find the actual length of car
1/18 = 9/Actual length of car in real
Actual length of car in real = 9 × 18
Performing multiplication
Actual length of car in real = 162 inches
Converting length from inches to feet -
1 inch = 0.0833 feet
162 inch = 0.0833×12
162 feet = 13.5 feet
Hence, the actual length of car in real is 13.5 feet
