Answer:
Step-by-step explanation:
I think A repent 100 and B repent 10
In this right triangle we have the opposite and adj which is tangent
tan 37=9/x
since we have the x in the bottom so we switch it with tan37
which is
x=9/tan 37
x=11.94340339
x=11.94
T=60+7x
x is for numbers of hours worked
t stands for total pay
Answers:
- a = 475
- r = -0.5
- f(3) = 59.4
=======================================================
Explanation:
Any exponential function is of the form y = a*b^x
Comparing that to y = 475*(0.5)^x, we see that a = 475 and b = 0.5
Set b equal to 1+r and solve for r
1+r = 0.5
r = 0.5-1
r = -0.5
The negative r value tells us that the growth rate is -50%, in other words, we have a 50% decay rate. The amount drops by 50% each time x goes up by 1. This is the same as saying the amount cuts in half each time x goes up by 1.
-----------------------
Lastly, plug in x = 3 to find f(3)
f(x) = 475(0.5)^x
f(3) = 475(0.5)^3
f(3) = 59.375
f(3) = 59.4
Answer:
Center = (1,2) radius = 2
Step-by-step explanation:
I used Demos to graph the circle.
Then I added two line to find the center of the circle
The radius is 2
