Consider an angle with a measure of θ=225∘.

Sketch a diagram representing the situation.

Determine the measure of the reference angle for this angle.
 _______°   

Now, determine the exact values of the following expressions. Your answers should include fractions and square roots, and not decimal values.

cos(θ)=

sin(θ)=

tan(θ)=

​

Answers

Answer:

cos 225° = [tex]-\frac{\sqrt{2} }{2}[/tex]

sin 225° = [tex]-\frac{\sqrt{2} }{2}[/tex]

tan 225° = 1

Step-by-step explanation:

I cannot sketch a diagram, but a 225° angle is a 3rd quadrant angle and the reference angle is 45°   (225 - 180 = 45)

cos and sin are negative in the 3rd quadrant and the tan is positive

cos 225° = - cos 45° = [tex]-\frac{\sqrt{2} }{2}[/tex]

sin 225° = -sin 45° = [tex]-\frac{\sqrt{2} }{2}[/tex]

tan 225° = tan 45° = 1

Q1: A number minus 4 is greater than 2 times a number

Answers

Answer:

x - 4 > 2x

(see below to solve for x if needed)

Step-by-step explanation:

"Greater than" is key word for the greater than symbol: >.

"A number" can be represented by x.

So "a number minus four" would be x - 4 and "two times a number" would be 2x.

So "A number minus 4 is greater than 2 times a number" is:

x - 4 > 2x

If you were to solve for x, it would be:

x - 4 > 2x

-x         -x

-------------

-4     > x

x < -4

Chloe scored 24 points over the first 12 games of the basketball season. She scored 112 points over the last 16 games of the season. How many more points per game did Chloe score in the last 16 games of the season?

Answers

Answer:

5 points

Step-by-step explanation:

First, find how many points per game she scored over the first 12 games:

24/12

= 2 points per game

Now, find how many she scored in the last 16 games:

112/16

= 7 points per game

Find the difference:

7 - 2

= 5

So, she scored 5 more points per game in the last 16 games

Answer:

first 12 games- 24/12= 2ppg

Last 16 games- 112/16= 7ppg

7-2= 5 points per game more

Nikki brought a patio set on sale for $480 the original price was 850 what is the rate of discount

Answers

Answer:

43.5%

Step-by-step explanation:

Substitute the original price of $850 and the sale price of $480 to find

amount of discount=850−480=370

Use the amount of discount, $370, to find the discount rate. Use the equation

amount of discount=discount rate×original price.

Rearrange the equation to solve for the unknown value.

discount rate=amount of discountoriginal price

Substitute in the known values and solve to find the discount rate.

370850=0.435=43.5%

Thus, the discount rate on the patio set was 43.5%.
