Use the unit circle to find cos (-270°)

Answers

Answer:

\cos (-270\degree)=0.

Step-by-step explanation:

We want to find the value of \cos (-270\degree).

Note that;

\cos (-\theta)=\cos (\theta)

This implies that;

\cos (-270\degree)=\cos (270 \degree)

Also 270 degrees is a quadrantal angle.

On the unit circle, \cos (270\degree) is the x-coordinate of the point (0,-1)

Hence, \cos (-270\degree)=0.

Ben owns a townhome valued at $195,000, but still owes $120,000 on the loan. Ben has $5,000 in savings and a balance of$1,400 on his credit cards. There is a balance of $20,000 owed on Ben's car which is valued at $38,000. What is Ben's net

worth?

a $96,600

b. $97,600

CS99 400

d. $106,600

Answers

Answer:

The correct answer is C= $99.400

Step-by-step explanation:

You need to sum all he has and then rest all he owes

The car has a balance of 20000 owed so 38000-20000=$18000 to sum

%195000+$5000+$1400+$180000=$219400

Then you rest what he owes= $219400-$120000=$99400

Thats Ben's net worth

The Answer is C=$99400

The car has a balance of 20000 owed so 38000-20000=$18000 to sum

Answer:

A) 96,600

Step-by-step explanation:

"Balance of $1,400 on his credit cards" refers to a debt of $1,400, meaning you need to subtract it from his savings

Credit card: $5,000 - $1,400 = $3,600

Home: $195,000 - $120,000 = $75,000

Car: $38,000 - $20,000 = $18,000

Net: $3,600 + $75,000 + $18,000 = $96,600

Ralph spends 15 1/3 hours per month playing tennis. How many hours does he play tennis in a year? (There are twelve months in a year.)a. 182 2/3
b. 164
c. 184
d. 164 1/3

Answers

Number of hours that Ralph spends playing tennis in a month = 15 1/3 hours
                                                                                                    = 46/3 hours
Number of months in a year = 12 months
Then
The total number of hours that Ralph spends playing tennis = (46/3) * 12 hours
                                                                                                = 46 * 4 hours
                                                                                                 = 184 hours
So from the above deduction we can see that the total time spent by Ralph in playing tennis in a year is 184 hours. So the correct option among all the options given in the question is option "c". I hope the procedure is clear enough for you to understand.
184 hours a year cause 15x12 is 180hours  and 20x 12 is 240 minutes and 240 minutes is 4 hours so 180+4 is 184 hours
