(a) Prove that cos 3A = 4cos³ A - 3 cos A
Answer:
Step-by-step explanation:
cos 3A = cos (2A+A)
= cos 2A cos A - sin 2A sin A
= (2cos[tex]A^{2}[/tex] -1) cos A - (2sinAcosA) sinA
=2cos[tex]A^{3}[/tex]-cosA - 2sin[tex]A^{2}[/tex]cosA
=2cos[tex]A^{3}[/tex]-cosA -2(1 -cos[tex]A^{2}[/tex])cosA
=2cos[tex]A^{3}[/tex] - cosA - 2 cosA+ 2cos
⇒ ∴4cos[tex]A^{3}[/tex] -3 cosA

Answer:
∠1 = 64°
∠2 = 116°
Step-by-step explanation:
Let x = supplement and x + 52 = the one angle. Set up this equation:
(x) + (x + 52) = 180
2x + 52 = 180
Subtract 52 from both sides.
2x = 128
Divide both sides by 2, and you get x = 64.
Keep in mind this equals the supplement. To find the measure of the other angle, add 52 and you get 116

Bob is filling his 7000-gallon swimming
pool. His hose fills at a rate of 22.2
gallons per minute. To the nearest
minute, how long will it take to fill his pool
Answer:
315 minutes
Step-by-step explanation:
To solve this, we must divide the gallons of the swimming pool by the rate of gallons per minute.
7,000 gallons divided by 22.2 minutes equals 315.3 minutes.
We can round this to 315.
315 minutes is how long it will take to fill the pool.

The length of a rectangle is six times its width.
If the area of the rectangle is 600 in, find its perimeter.
Answer:
140 in
Step-by-step explanation:
x = length
y = width
x = 6y
area = x × y = 600 in² (I hope you forgot to put the ² on the in and not your teacher).
perimeter = 2x + 2y
using the first equation as substitute in the second equation we get
6y × y = 600
6y² = 600
y² = 100
y = 10 in
x = 6y = 6×10 = 60 in
perimeter = 2×60 + 2×10 = 120 + 20 = 140 in
The table shows the changes in elevation of a hiker each day for three days. How many miles of elevation must the hiker gain on the fourth day to gain 1/4
mile of elevation over the four days?
days:
1: -1/4
2: 1/2
3: -1/5
4:?
Using operations of sum/subtraction with fractions, it is found that he must gain [tex]\frac{1}{5}[/tex] of miles of elevation on the fourth day.
---------------------------
On the first day, his net elevation was of [tex]-\frac{1}{4}[/tex]On the second day, his net elevation was of [tex]\frac{1}{2}[/tex]On the third day, his net elevation was of [tex]-\frac{1}{5}[/tex]On the fourth day, his net elevation was of x.We want to total to be of [tex]\frac{1}{4}[/tex].Thus, we have to solve the sum of the four days equal to [tex]\frac{1}{4}[/tex] for x.---------------------------
[tex]-\frac{1}{4} + \frac{1}{2} - \frac{1}{5} + x = \frac{1}{4}[/tex]
[tex]\frac{-5 + 10 - 4 + 20x}{20} = \frac{1}{4}[/tex]
[tex]\frac{1 + 20x}{20} = \frac{1}{4}[/tex]
[tex]1 + 20x = 5[/tex]
[tex]20x = 4[/tex]
[tex]x = \frac{4}{20} = \frac{1}{5}[/tex]
He must gain [tex]\frac{1}{5}[/tex] of miles of elevation on the fourth day.

susie bought 4 hair bows for 0.50 each which equation shows how to find the total cost in dollars and cents of the hair bows bought
Hi! I'm happy to help!
We need to look for clues in the problem to see which operation we are going to use. We see the word each, which represents multiplication.
So, we will multiply 4 by 0.50 to get our cost.
4×0.5
2
So, the cost of the 4 hair bows is $2.00.

Step-by-step explanation:
is a two digit number always less than a three digit number
Option C is correct. Whether a two-digit number is always less than a three-digit number depends on the first digit in the number.
A number can be a combination of a positive and negative integer. For example,
23 is a 2 positive digits number -231 is a 3 digits number (containing a negative and positive integer)We can see from the numbers that 23 (a two digits number ) is greater than -230 (a 3 digits number) which falsifies the claim that a two-digit number is always less than a three-digit number.
The veracity of the claim all depends on the first digits of the number (whether it is a positive or negative integer)

If XR is (2x + 5) inches long and RY is 22 inches long, what
is the value of x? What about XR? What about XY?
helpp
The value of x is 8.5 inches
The value of XR is 22 inches
The value of XY is 44 inches
If R is the midpoint between X and Y, it means that the length of /XR/ and /RY/ are equal
If /RY/ = 22, then /XR/ = 22 also
XR = (2x + 5) = 22
To determine the value of x , combine similar terms
2x = 22 - 5
2x = 17
x = 8.5 inches
The value of XR = 22 inches
Value of XY = 22 + 22 = 44 inches

For f(x) = 2x + 1 and g(x) = x^2 - 7, find (f-g)(x)
Answer:
[tex]\displaystyle (f - g)(x) = -x^2 + 2x + 8[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]\displaystyle f(x) = 2x + 1 \text{ and } g(x) = x^2 - 7[/tex]
And we want to find:
[tex]\displaystyle (f- g)(x)[/tex]
Recall that:

2(8x-4)-2x < 4x+12
the sign is supposed to be less than or equal to
Answer: x < 2
Step-by-step explanation:
Given expression
2 (8x - 4) - 2x < 4x + 12
Expand parentheses and apply the distributive property
16x - 8 - 2x < 4x + 12
Combine like terms
(16x - 2x) - 8 < 4x + 12
14x - 8 < 4x + 12
Add 8 on both sides
14x - 8 + 8 < 4x + 12 + 8
14x < 4x + 20
Subtract 4x on both sides
14x - 4x < 4x + 20 - 4x
10x < 20
Divide 10 on both sides
10x / 10 < 20 / 10

How do you solve question 1
9514 1404 393
Answer:
(A) 1 only
Step-by-step explanation:
Factor numerator and denominator and see what cancels.
[tex]f(x)=\dfrac{2x^2+14x-16}{x^2-9x+8}=\dfrac{2(x-1)(x+8)}{(x-1)(x-8)}=\dfrac{x-1}{x-1}\cdot\dfrac{2(x+8)}{x-8}\\\\f(x)=\dfrac{2x+16}{x-8}\qquad x\ne1[/tex]
The factor of x-1 in the original denominator means the expression is undefined at x=1. The reduced expression is defined there, so the discontinuity at x=1 could be removed by defining f(1) = -18/7.
There is a removable discontinuity at x=1 only. The discontinuity at x=8 is a vertical asymptote where the function changes sign. It cannot be removed by defining a value for the function there.
