Answer:
A
Step-by-step explanation:
The cosine of a right triangle is the adjacent over the hypotenuse. If the cosine is -3/5 then it must be a right triangle with sides 3, 4, & 5 since this is a Pythagorean triple. This means the sin will be -4/5. We know its negative because the tangent is positive so this is the 3rd quadrant where both Sine and Cosine are negative.
2 students more were introducced in the class and each group had 8 people
Mr. Rodriguez invest *$2,000 in a savings plan the savings account pays an annual interest<span> **rate of 5.75 how much will Mr. Rodriguez earn if he leave his money in the savings plan for ***10 years?</span>
The bolded parts have a certain number of stars before it. That correlates with the below:
The equation is I = P * R * T
I = interet
* P = pay
**R = rate
***T = time (measured in years)
The pay is $2000
The rate is 5.75%
The time is 10 years.
You need to convert the rate into a decimal.
5.75% = 0.0575
2000 * 0.0575 * 10 = 1150
The answer is $1150
After 10 years, Mr. Rodriguez will have earned $1,150
Hope I helped!
