Solve. Between [0, 2pi]
2cos^2x+7cosx+3=0
9514 1404 393
Answer:
x = {2π/3, 4π/3}
Step-by-step explanation:
The equation can be factored as ...
(cos(x) +3)(2cos(x) +1) = 0
The solutions are the values of x where the factors are zero.
cos(x) +3 = 0
cos(x) = -3 . . . . . . no real solution
__
2cos(x) +1 = 0
cos(x) = -1/2
x = arccos(-1/2) = 2π/3
The other solution in the desired interval is ...
x = 2π -(2π/3) = 4π/3
The solutions are x∈ {2π/3, 4π/3}.

Answer:
4√2 = 5.657
9 - 5.657 = 3.343
√3.343 = 1.828
2√2 = 2.828
1.828 - 2.828 = -1
Answer:
I also got -1 doing it on my calculator
Step-by-step explanation:
i first converted it to exponent form to get rid of the radical
(9 - 4(2)^1/2 )^1/2 - 2(2)^1/2 solve inside the first parenthsis
(9 - 4(1.414)^1/2 - 2(2)^1/2
(9 - 5.656)^1/2 - 2(2)^1/2 √2 times 4
(3.343)^1/2 - 2(2)^1/2 9 - √2 times 4
1.828 - 2(2)^1/2 √(9 - √2 times 4)
1.828 - 2(1.414) √(9 - √2 times 4) - 2√2
1.828 - 2.828 √(9 - √2 times 4) - 2√2
-1
I need help with these, the answer options are as follows: always true, sometimes true, never true
Thank you!!
A copy machine makes 136 copies in 4 minutes and 15 seconds. How many copies does it make per minute?
Answer:
The copy machine makes 32 copies per minute.
Step-by-step explanation:
Given that a copy machine makes 136 copies in 4 minutes and 15 seconds, to determine how many copies does it make per minute, the following calculation must be performed:
15 seconds = 0.25 minutes
136 / 4.25 = X
32 = X
Therefore, the copy machine makes 32 copies per minute.
What is the expression and value of "six less than the quotient of a number and two, increased by ten" when n= 8? O 122 - 6+ 10; when n= 8, the value is 8. 12 O B- 6- 5+10; when n = 8, the value is 12. 02-6+10; when n = 8, the value is 11. O 6-9 +10, when n = 8, the value is 9
Answer:
the answer is 8
Step-by-step explanation:
the expression is written as (n/2 - 6)+ 10
therefore when n=8..
(8/2 - 6) + 10
we now have, (4-6)+10
(-2)+10=8...

What is the perimeter of the figure?"
9514 1404 393
Answer:
46 yd
Step-by-step explanation:
The sum of horizontal lengths across the top is 8+6 = 14 yd. The length across the bottom is the same, so the total of horizontal lengths is
14 yd +14 yd = 28 yd
The sum of vertical lengths at the right is the same as the sum of vertical lengths at the left, 9 yd, so the total of vertical lengths is ...
9 yd + 9 yd = 18 yd
The total of all lengths around the perimeter of the figure is ...
28 yd + 18 yd = 46 yd

Example 5:
Mrs. Williams writes the following number on the board.
276,954
She instructs her students to write a number where the value of the 6 in their number is 10
times greater than the value of the 6 in the number on the board. Duwan writes the number
286,123. Is his answer correct? Explain how you know.
Answer:
No Duwan is in incorrect.
Step-by-step explanation:
When it asks for a number to be 10x greater, the answer would be in a digit that is 1 greater. For example 10x greater than 10 would be 100. You move the digit up once. An answer that Duwan could have used is: 260,000.

Darby’s Breakfast table an square tabletop what are your area of 36 ft.²
Answer:
Diagonal length = 8.59
Step-by-step explanation:
To find the diagonal length, we need the length of the sides. We find the length of the sides by finding the square root of 36, which is 6. Then, we use this equation (see attached image)

What is the approximate length of the missing side of a
right triangle with hypotenuse of 16 cm and other side of
15 cm?
Answer:
The approximate length of the missing side is of 5.57 cm.
Step-by-step explanation:
Pythagorean Theorem:
In a right triangle with sides a and b and hypotenuse c, the Pythagorean theorem states that:
[tex]a^2 + b^2 = c^2[/tex]
In this question:
[tex]a = 15, c = 16[/tex]
We want to find b. Then
[tex]a^2 + b^2 = c^2[/tex]
[tex]15^2 + b^2 = 16^2[/tex]
[tex]b^2 = 256 - 225[/tex]
[tex]b^2 = 31[/tex]
[tex]b = \sqrt{31}[/tex]
[tex]b = 5.57[/tex]
The approximate length of the missing side is of 5.57 cm.

Answer:
D Not similar
Step-by-step explanation:
For similar triangles the sides are always in proportions.
Here two sides are in proportion but third side isn't. So triangles are not similar.

what is the value of a when we rewrite 8^x as a^-x/9
Answer:
[tex]a = \frac{1}{134217728}[/tex]
Step-by-step explanation:
Given
[tex]8^x = a^{-x/9}[/tex]
Required
Find a
Take log of both sides
[tex]log(8^x) = log(a^{-x/9})[/tex]
Apply law of logarithm
[tex]x\ log(8) = (-x/9) log(a)[/tex]
Divide both sides by a
[tex]log(8) = -\frac{1}{9} log(a)[/tex]
Multiply both sides by -9
[tex]-9\ log(8) = log(a)[/tex]
Apply law of logarithm
[tex]log(8^{-9}) = log(a)[/tex]
Cancel out log
[tex]8^{-9} = a[/tex]
Rewrite as:
[tex]a = 8^{-9}[/tex]
Apply law of indices
[tex]a = \frac{1}{8^9}[/tex]
[tex]a = \frac{1}{134217728}[/tex]
