Answer: y = 1200m + 57,600
Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.
So, we have (2,60000) and (7,66000)
y = mx + b
66000 = 7m + b
60000 = 2m + b (-)
________________________
6000 = 5m
m = 6000/5 = 1200
60000 = 2m + b
60000 = 2.1200 + b
60000 = 2400 + b
b = 60000 - 2400
b = 57600
y = mx + b
y = 1200m + 57,600
Answer:
(4,-2)
Step-by-step explanation:
-y = 1/2(4)
-y = 2
divide both sides by -1
y = -2
Answer:
volume = 24,501.42
Step-by-step explanation: the way i did it:
first find the radius, 34 divided by 2 = 17π
then multiply the radius by itself 17 x 17 = 289
after, multiply 289 by 27 to get 7,803
then multiply 7803 by 3.14 to get 24,501.42
Hope this is correct!
(p.s.) if you do it on a calculator and use the pi symbol (π) the answer would be 24,513.84
