Find all solutions for the following equations. Write your answers in radians using exact values. (Enter your answers as a comma-separated list. Let k be any integer.) sin 2x cos x cos 2x sin x
Answer:
Step-by-step explanation:
Given that:
sin2xcos x + cos2xsin x = -1
Recall that;
SInAcosB + cosASinB = SIn (A+B)
SIn (2x +x) = -1
Sin (3x) = -1
[tex]x = \bigg [\dfrac{Sin ^{-1} (-1)}{3} \bigg ][/tex]
[tex]x = \dfrac{\pi}{2} + \dfrac{2 \pi \ k}{3}[/tex]
[tex]x = \dfrac{\pi}{2}, \dfrac{7 \pi}{6}, \dfrac{11 \pi}{6}[/tex]

I made a PDF. Last time I tried doing this, the PDF did not work. Please tell me if the PDF is not working for you. My handwriting is also horrible XD. And sorry for my way of explaining, this is just how I was thought it, so it probably won't make sense.
So basically I'll try walking through what is going on in the picture.
So basically I just multiplied 2,412 by 24. I will incorporate the decimals later.
After multiplying, I got 57,888.
Now I will include the decimals.
You can see on the right side of the picture I counted how many decimal places 24.12 has. It has 2 decimal places.
Then I counted how many decimal places 2.4 has. It has 1 decimal place.
So I have to totally add the decimal places now.
2 decimal places plus 1 decimal place is 3 decimal places.
Three decimal places into 57,888 is 57.888.
2.4 × 24.12 is 57.888.

The error is the contractor didnt take into account that there are 5 dozen gloves not 5 pairs of gloves. He calculated $73.20/5, which gave him $14.64.
Step-by-step explanation:
1 dozen = 12
5 dozen = 12 * 5 = 60
Therefore, you have 60 pairs of gloves.
He purchased all 60 pairs of gloves for $73.20.
73.20/60 = $1.22
This is how much one pair of gloves cost.

what’s the slope?
Answer: 2
Step-by-step explanation:
(x1,y1) = (-1,0)
(x2,y2) = (3,8)
m = (8–0)/(3-(-1))
m = 8/(3+1)
m = 8/4
m = 2

area
of a square room is 2601m squared Find
The
find its perimeter
Answer:
perimeter = 204m
Step-by-step explanation:
area of a square = side²
2601m² = side²
√(2601m²) = √side²
51m = side
perimeter of a square = 4*side
perimeter of this square = 4*51
perimeter of this square = 204m

The access code for a car's security system consists of digits. The first digit cannot be and the last digit must be . How many different codes are available?
Complete Question
The access code for a car's security system consists of 6 digits, the first digit cannot be 8 and the last digit must be odd, how many different codes are available
Answer:
There are 450000 possible different codes
Step-by-step explanation:
Given
Code = 6 digits
First = All but 8
Last = Odd
Required
Determine the possible number of codes
Analyzing each individual digit that makes up the code.
First: can be any of 0,1,2,3,4,5,6,7,9 ----- 9 possible numbers
Second, Third, Fourth and Fifth can be any of 0,1,2,3,4,5,6,7,8,9 since there's no restriction ----- 10 possible numbers
Last can be any of: 1,3,5,7,9 ----- 5 possible numbers
So, the number of possible selections is:
[tex]Selection = 9 * 10 * 10 * 10 * 10 *5[/tex]
[tex]Selection = 450000[/tex]
Hence, there are 450000 possible different codes

Line b passes through the point ( (6,4) and has a slope of -2. What is the equation of Line b in standard form?
2x + y = -11
x + 2y = -14
x + 2y = -16
2x + y = 16
Answer:
Equation of line b in standard form is: [tex]\mathbf{2x+y=-11}[/tex]
Option A is correct.
Step-by-step explanation:
We need to find equation of line b that passes through the point ( (6,4) and has a slope of -2.
First we need to find y-intercept of line using formula: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Using m=-2 , x=6 and y=4 the y-intercept will be:
[tex]y=mx+b\\4=-2(6)+b\\4=12+b\\b=4-12\\b=-11[/tex]
Now finding the equation of line having slope m=-2 and y-intercept b=-11
[tex]y=mx+b\\y=-2x-11[/tex]
Writing the equation in standard form
[tex]y=-2x-11\\2x+y=-11[/tex]
So, equation of line b in standard form is: [tex]\mathbf{2x+y=-11}[/tex]
Option A is correct.
