The starting salary for delivery driver is 35,000 per year with a yearly increase of 3% which type of function best models this situation

Option B

Step-by-step explanation:

The complete question is

The starting salary for a delivery driver is $35,000 per year with a yearly increase of 3%. which type of function best models this situation? a) exponential b) linear c) quadratic d) radical

Solution

After 1 year the salary of delivery boy will be

Salary of delivery boy after 2nd year =

Salary after 3rd year

The growth in salary is linear as depicted from the values obtained.

Hence, option B is correct

We are given
m∠R = 30°
m∠PQS = 50°
SR = 5 cm.

I have attached the diagram for this problem and what is asked here is the length of line segment PQ

Since SQ bisects PQR, then 
angle SQR = 50°

using the sine law
SQ / sin R = SR / sin SQR
Subsituting
SQ / sin 30 = 5 / sin 50
SQ = 3.26

Using trigonometry
cos PQS = PQ / SQ
cos 50 = PQ / 3.26
PQ = 2.10 cm
