I hope this helped you!
Answer:
A negative degree equation.
Step-by-step explanation:
cos(4*x) = cos(3*x)^2+sin(x)^2
Recall the following identities:
cos(4x) = cos⁴(x) - 6 cos²(x) sin²(x) + sin⁴(x)
cos(3x) = cos³(x) - 3 cos²(x) sin(x)
sin²(x) = 1 - cos²(x)
Then the equation
cos(4x) = cos²(3x) + sin²(x)
can be rewritten entirely in terms of cos(x) as
8 cos⁴(x) - 8 cos²(x) + 1 = 16 cos⁶(x) - 24 cos⁴(x) + 8 cos²(x) + 1
16 cos⁶(x) - 32 cos⁴(x) + 16 cos²(x) = 0
16 cos²(x) (cos²(x) - 1)² = 0
Now we can solve:
cos²(x) = 0 or (cos²(x) - 1)² = 0
cos(x) = 0 or cos²(x) - 1 = 0
cos(x) = 0 or cos²(x) = 1
cos(x) = 0 or cos(x) = -1 or cos(x) = 1
x = π/2 + 2nπ or x = -π/2 + 2nπ
… or x = π + 2nπ
… or x = 2nπ
where n is any integer.
Use the tables below to find (p - q)(2)
(p - q)(2) =
Answer:
(p - q)(2) = 5
Step-by-step explanation:
(p - q)(2)
= p(2) - q(2)
From the table for p(x)
when x = 2 , p(2) = 3
From the table for q(x)
when x = 2 , q(2) = - 2
Then
(p - q)(2) = 3 - (- 2) = 3 + 2 = 5
Answer: it’s 1 not 5 or -5

Aaron took a taxi from his house to the airport. The taxi company charged a pick-up fee of $2 plus $3.50 per mile. The total fare was $58, not including the tip. Which equation could be used to determine xx, the number of miles in the taxi ride?
Answer:
58 = 3.5x + 2
Step-by-step explanation:
Since $3.50 is charged for every mile, we multiply x by 3.5 like this: 3.5x
$2 is already added on as a free so + 2
$58 is the total amount of money for all of the charges including the per mile and pick-up fee.
This was we can solve for the number of miles, x
58 = 3.5x + 2
- 2 - 2
56 = 3.5x
56/3.5 = 3.5x/3.5
x = 16
The taxi drove a total of 16 miles

show that a^12 can be written as a perfect square and a perfect cube
Answer:
Step-by-step explanation:
Doing this the long way, write a^12 as a product of "a"s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
Now group them into groups of 4
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube
Now do the same thing with groups of 6s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
a^12 = (a^6)^2
So the two answers are
Perfect cube: [(a^4)]^3
Perfect square: (a^6)^2

Step-by-step explanation:
A function does not have reoccurring x values that are identical in its points. You can have reoccurring y values in a function (ex y=sin(x)).
Find the value of 4w +1 given that -3w-7=2.
Simplify your answer as much as possible.
Answer:
-11
Step-by-step explanation:
-3w - 7 = 2
-3w (- 7 + 7) = 2 + 7
-3w = 9
-3w/-3 = 9/-3
w = -3
4w + 1
4(-3) + 1
-12 + 1
-11
Answer:
4w + 1 = -11
Step-by-step explanation:
Solving -3w - 7 = 2
By adding 7 to both sides of the equation we get -3w = 9
to get to w = ... we need to divide both sides with -3, which gives us
w = -3. You can check this answer by putting it back into the original equation ( -3 * -3 - 7 does equal 2, which means our solution for w is correct.
Now all we have to do is put our solution for w into the remaining equation:
4 * -3 + 1 = -12 + 1 = -11
-16 + the quotient of a
number and -4 is -3
Answer:
76
Step-by-step explanation:
let the number be x
Then 16 + x/-4 = -3, so
x/-4 = -16-3 = -19 (add -16 on both sides)
x = -4*-19 = 76 (multiply by -4 on both sides)

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $9 monthly fee and charges an additional $0.17 for each minute of calls. The second plan has a $24 monthly fee and charges an additional for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
88.23
Step-by-step explanation:
The equation for the first plan is:
9 + 0.17x
The equation for the second plan is
24
Then you set the two equations equal to each other
9 + 0.17x = 24
Subtract on both sides
0.17x = 15
Divide
x = 88.23

Which one? 10 points

Answer:
n=64
Step-by-step explanation:
Let think algebracially. One of the terms in the set is a fraction. A natural number must be a whole number so this means that
n must be a multiple of 8.
*N must be a multiple of 8.
Look at the third term, we know that a square root must produce a perfect square term to get a natural number. So n must be a multiple of 8 that makes the radical a perfect square
Perfect squares are.
0,1,4,9,16,25,36,49,64,81,100,121,144,169,196,225, 256, 289
N has to compute a sum greater than 225 so the perfect squares we look at must be greater than 225.
The next one is 256 but
[tex]256 - 225 = 31[/tex]
[tex]31 \div 8 = \frac{31}{8} [/tex]
which isn't rational so 256 won't work. Let try 289
[tex]289 - 225 = 64[/tex]
[tex]64 \div 8 = 8[/tex]
and
[tex]33 + 64 = 97[/tex]
So 64 works. 64 is the answer
n=64

Solve each for X. Show your work
10-1/2x = 6 + 3x
Answer:
[tex]x = \frac{8}{7} [/tex]
Step-by-step explanation:
[tex]10 - \frac{1}{2} x = 6 + 3x[/tex]
[tex]20 - x = 12 + 6x[/tex]
[tex]20 - x - 6x = 12 + 6x - 6x[/tex]
[tex]20 - x - 6x = 12[/tex]
[tex] - x - 6x = 12 - 20[/tex]
[tex] - 7x = 12 - 20[/tex]
[tex] - 7x = - 8[/tex]
