Answer:
949$
Step-by-step explanation:
You get 460$ the first year, then 488 in the second.
The answer is -25. Hope this helps!!
Inverse, baseically
replace f(x) with y
switch all x and y
solve for y
replace y with f⁻¹(x)
f(x)=6(x+2)-3
replace with y
y=6(x+2)-3
switch x and y
x=6(y+2)-3
solve for y
x=6y+12-3
x=6y+9
minus 9
x-9=6y
divide 6
1/6x-3/2=y
replace
f⁻¹(x)=1/6x-3/2
when x=21
f⁻¹(21)=1/6(21)-3/2
f⁻¹(21)=21/6-3/2
f⁻¹(21)=21/6-9/6
f⁻¹(21)=12/6=
f⁻¹(21)=2
answer is f⁻¹(21)=2
inverse function is
f⁻¹(x)=1/6x+3/2
Answer: x = 58°
Step-by-step explanation:
Sine = opposite leg ÷ hypotenuse
We need to find the hypotenuse first with the Pythagorean theorem.
a² + b² = c²
5² + 8² = c²
25 + 64 = c²
89 = c²
√c² = √89
c = 9.43398
c ≈ 9.43
Sine = opposite leg ÷ hypotenuse
Opp. leg - 8
Hypotenuse - 9.43
To find this, you have to use the calculator
Make sure the calculator is on scientific
If your calculator is on your computer and in full screen, find 8 ÷ 9.43 and then click sin⁻¹, you should get 58.03334
If your calculator is on your computer in mini screen, find 8 ÷ 9.43. This time, click the arrow that looks smth like this: ↑
When you do that, you should be able to see sin⁻¹, so you click that and you'll also get 58.03334
58.03334 ≈ 58
x = 58°
