Rewrite with only sin x and cos x.
sin 3x - cos x
Answer:
sin (3 x) - cos (x)=
= sin (2x + x) - cos (x)=
= sin 2x * cos x + cos 2 x * sin x - cos x = ( using additional formulas )
= 2 sin x cos² x + ( cos² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - sin² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - 2 sin² x ) sin x - cos x =
= 2 sin x cos² x + sin x - 2 sin³ x - cos x

Answer: 8 1/4 miles
Step-by-step explanation:
I think your question isn't well written and should be:
Nathan jogged 2 1/4 miles on Monday. On Wednesday, he jogged 3 1/3 miles and on Friday, he jogged 2 2/3 miles. How far did Nathan jog altogether?
This will be:
= 2 1/4 + 3 1/3 + 2 2/3
= 2 3/12 + 3 4/12 + 2 8/12
= 7 15/12
= 7 + 1 3/12
= 8 3/12
= 8 1/4 miles

A car is purchase at $20000.The value of the car depreciates at 12.5% a year. What will the value of the car be to the nearest cent after 11 years
Answer: $4603.82
Step-by-step explanation:
Given
The initial cost of a car is [tex]P=\$20,000[/tex]
The rate of depreciation is [tex]i=12.5\%[/tex]
Depreciated value after n years is given by
[tex]\Rightarrow P(1-\frac{i}{100})^n\quad \text{where n=no. of years}[/tex]
Value after 11 years
[tex]\Rightarrow 20,000(1-\frac{12.5}{100})^{11}\\\\\Rightarrow 20000(0.875)^{11}=\$4603.82[/tex]

In two weeks, your class collected more than 380 cans of food for the annual food drive. In the first week, 145 cans were collected. How many cans c of food were collected in the second week? Write and solve an inequality.
145 + c < 380; c < 235
c + 145 > 380; c > 525
c − 145 ≥ 380; c ≥ 525
145 + c > 380; c > 235
Answer:
Step-by-step explanation:
145+c>380 subtract 145 from each side
c>235 so the answer is
145+c>380; c>235
A line that is parallel to the line y=3x-8 and passes through the point (-1,6)
The equation of the parallel line is...
Answer:
y = 3x + 9
Step-by-step explanation:
If the line is parallel, that means it will have the same slope. So, the line will also have a slope of 3.
Using y = mx + b, plug in the slope and given point, and solve for b:
y = mx + b
6 = 3(-1) + b
6 = -3 + b
9 = b
Plug in the slope and b into y = mx + b
y = 3x + 9
So, the equation of the parallel line is y = 3x + 9

Jade spent ⅓ of her math homework time working on word problems. What fraction of an hour did she spend working on word problems?
Answer:
If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.

Points (-2, 4) and (-1,1) lie on the same line. Which of the following equations represents the line?
A. y - 1 = -}(x + 1)
B. y - 1 = -3(x + 1)
C. y - 1 = -}(x - 1)
D. y - 1 = -3(x - 1)
Answer:
A
Step-by-step explanation:
There are 2 ways you can do this. I'll show you one!
1. Find the Slope
a. use the slope formla: (y1-y2)/(x1-x2)
(4-1)/(-2-1)= 3/-3= -1
This eliminates both B and D, as their slopes are -3
2. Now analyze the last 2 equations
a. A goes through the ordered pair (-1, 1)
b. C goes through the ordered pair (1, 1)
The line we want goes through (-1, 1), so A is the correct answer!
[tex]y-1=-3(x+1)[/tex] equation represents the line.
What is point slope form?The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.
Given points
[tex](x_{1} ,y_{1} )[/tex] = (-1, 1)
[tex](x_{2} ,y_{2} )[/tex] = (-2, 4)
Using point slope form
We know that the equation of line passing through points [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] is
[tex]y-y_{1} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }( x-x_{1})[/tex]
Therefore equation of line passing through points (-1, 1) and (-2, 4) is
[tex]y-1=\frac{4-1}{-2+1}(x-(-1))[/tex]
[tex]y-1=\frac{3}{-1} (x+1)[/tex]
[tex]y-1=-3(x+1)[/tex]
Option B is correct.

When is the best time to use square roots to solve a quadratic? Choose the one BEST
answer.
A. Perfect square trinomials
B. Difference of squares
C. When there is no b term
D. When the constants are perfect squares
Answer: D, When the constants are perfect squares.
Step-by-step explanation:
the “best” method whenever the quadratic equation only contains x2 terms. That implies no presence of any x term being raised to the first power somewhere in the equation.
