use a power reduction identity to simplify 8cos^4x
The simplified value is 8*cos^4(x) = 3+ 4 cos2x + cos 4x.
What is power reduction identity?The trigonometric power reduction identities allow us to rewrite expressions involving trigonometric terms with trigonometric terms of smaller powers. This becomes important in several applications such as integrating powers of trigonometric expressions in calculus.
Given:
Using the power reduction identity, we have that:
cos² x= 1/2( 1+ cos 2x)
cos^4(x) = (cos² x)²= (1/2( 1+ cos 2x))²
cos^4(x) = 1/4( 1+ cos² 2x+ 2 cos (2x))
Again, cos² 2x= 1/2( 1+ cos 4x)
cos^4(x) = 1/4( 1+ 1/2( 1+ cos 4x)+ 2 cos (2x))
cos^4(x) = 1/4( 1+ 1/2 +1/2 cos 4x+ 2 cos (2x))
cos^4(x) = 1/4( 3/2 + 2 cos2x + 1/2 cos 4x)
8*cos^4(x) = 8*1/4( 3/2 + 2 cos2x + 1/2 cos 4x)
8*cos^4(x) = 2( 3/2 + 2 cos2x + 1/2 cos 4x)
8*cos^4(x) = 3+ 4 cos2x + cos 4x

a. When there are 20 guests attending, the price is less at the Moonlight Hall.
b. It always costs more to use the Riverside Hall.
c. When there are 20 guests attending the price is $2500.
d. It always costs more to use the Moonlight Hall.
Answer:
Answer 1: a. Moonlight: C=75n+1000
Riverside: C=50n+1500
Answer 2: c. The solution coordinates are c. (20, 2500)
Answer 3: c. When there are 20 guests attending the price is $2500.
Step-by-step explanation:
Moonlight Hall:
Fixed cost = $1000
Cost per guest = $75
Cost of 'n' guests = 75 [tex]\times n[/tex]
Total cost of moonlight hall = Fixed cost + Cost of 'n' guests
[tex]\Rightarrow 1000 + 75 \times n[/tex]
Riverside Hall:
Fixed cost = $1500
Cost per guest = $50
Cost of 'n' guests = 50 [tex]\times n[/tex]
Total cost of moonlight hall = Fixed cost + Cost of 'n' guests
[tex]\Rightarrow 1500 + 50 \times n[/tex]
Hence, Answer 1:
a. Moonlight: C=75n+1000
Riverside: C=50n+1500
Answer 2: Coordinates of solution:
Option c. (20,2500) satisfies both the equation.
When there are 20 number of guests, the cost of both moonlight and riverside hall comes out to be 2500.
Moonlight Hall cost
[tex]75 \times 20 + 1000\\\Rightarrow \$2500[/tex]
Riverside Hall cost
[tex]50 \times 20 + 1500\\\Rightarrow \$2500[/tex]
Answer 3: c. When there are 20 guests attending the price is $2500.

Tanzila is selling tickets to the MS127 musical. On the first day of ticket sales she sold 2 adults tickets and 10 child tickets for a total of $78. Then she sold $67 on the second day by selling 8 adults tickets and 5 child tickets. What is the price of one adult ticket and one child ticket?
Answer:
One adult ticket is $4 and one child ticket is $7
Step-by-step explanation:
Make a system of equations
2x + 10y = 78
8x + 5y = 67
Solve by elimination, multiply the 2nd equation by -2
2x +10y = 78
-16x -10y = -134
Add the equations
-14x = -56
x = 4
The price of one adult ticket is $4
Plug 4 in as x to find y
2(4) + 10y = 78
8 + 10y = 78
10y = 70
y = 7
The price of one child ticket is $7

A farmer picked 600 portugals and oranges in total to be sold to the market. There are 3 times as many oranges as there are portugals. How many portugals are picked by the farmer?
Answer:
450 portugals
Step-by-step explanation:
in this question, we are tasked with calculating the number of portugals which are picked by the farmer
Firstly, let the number of portugals picked be p and the number of oranges picked be r.
Thus;
p + r = 600 ••••••••••(i)
Secondly there are 3 times as many oranges as there are portugals;
That would be;
3 * r = p
3r = p. •••••••••(ii)
substitute ii into i
3r + r = 600
4r = 600
r = 600/4
r = 150
P = 3r
p = 3 * 150 = 450

Part B What is the second step in evaluating the expression? A. Add 6 and 3. B. Divide 15 by 3. C. Multiply 3 by 7. D. Multiply 9 by 7. Part C Did Tyson use the order of operations to correctly evaluate the expression? Use the drop-down menus to show your answer. ; the value of the expression is
Answer:
Part A- (B) Divide 9 by 3
Part B- (C) Multiply 3 by 7
Part C- Tyson is wrong, because we found that the value of the expression was 27. Tyson must have solved the expression the way it was written from left to right and did not follow order of operations (PEMDAS).
*The value of this expression= 27.*
Step-by-step explanation:
Beware, we do NOT solve in the order the number sentence is given. By PEMDAS- first we solve Parenthesis (if any) , next we solve Exponents (if any), then we solve the Multiplication or Division based on whichever is first from the left, finally we solve Addition or Subtraction based on whichever appears first from the left, we solve first. So, following PEMDAS, there are no Parenthesis nor Exponents in your number sentence- the next step would be Multiplication or Division. So, which operation comes first from the left in your expression, between Multiplication or Division? Division, so we solve that, 9/3, which is 3. We rewrite the expression with the new answer- 6+ 3 x 7. Ok, so are there any more Division or Multiplication to solve so that we can move to the next step? Yes. 3 x 7, which is 21. We rewrite the expression again, 6+21, and the final answer is .....27. Therefore, going back in the process, remember the first operation we did and that is? DIVISION. Also, that means Tyson is wrong, because we found that the value was 27. Tyson must have solved the expression the way it was written from left to right and did not follow order of operations (PEMDAS).

How do you solve the three forms: Slope Y-intercept form Standard Form Point slope form
Answer:An equation in the slope-intercept form is written as
y=mx+b
Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept.
Example
Find the equation of the line
Choose two points that are on the line
Calculate the slope between the two points
m=y2−y1x2−x1=(−1)−33−(−3)=−46=−23
We can find the b-value, the y-intercept, by looking at the graph
picture28
b = 1
We've got a value for m and a value for b. This gives us the linear function
y=−23x+1
In many cases the value of b is not as easily read. In those cases, or if you're uncertain whether the line actually crosses the y-axis in this particular point you can calculate b by solving the equation for b and then substituting x and y with one of your two points.
We can use the example above to illustrate this. We've got the two points (-3, 3) and (3, -1). From these two points we calculated the slope
m=−23
This gives us the equation
y=−23x+b
From this we can solve the equation for b
b=y+23x
And if we put in the values from our first point (-3, 3) we get
b=3+23⋅(−3)=3+(−2)=1
If we put in this value for b in the equation we get
y=−23x+1
which is the same equation as we got when we read the y-intercept from the graph.
To summarize how to write a linear equation using the slope-interception form you
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Once you've got both m and b you can just put them in the equation at their respective position.
