BRAINLIEST FOR THE RIGHT ANSWER!!!

So, know the equation is:

205,000 - 1,100w - 12% = e

w = weeks he worked
e = earnings

If he works 4 weeks, then we fill in w with 4:

205,000 -1,100(4) - 12% = e

1,100 x 4 = 4,400

Now subtract:

205,000 - 4,400 = 200,600

Now to get his commission, turn the percent into a decimal:

12% ----> .12

Then multiply that by the sales after draws:

200,600 x .12 = 24072

That means that Jim Smith got $24072 from commission.

Hope this helps!

What is the equation of the inverse function A(n)=3n-20

Allisa [31]

Answer:

$A^{-1}(n)=\frac{1}{3}n+\frac{20}{3}$

Step-by-step explanation:

First, let's change those variables to x and y, just for the sake of convenience. In order to find the inverse of a function algebraically, switch the x and y coordinates, then solve for the new y. Letting y = A(n) and x = n (we will switch them back when we're done):

y = 3x - 20. This is linear; a line with a slope of 3 and a y-intercept of -20. When we switch the x and the y, we get:

x = 3y - 20. Now we solve for the new y. Begin by adding 20 to both sides:

x + 20 = 3y. Now divide both sides by 3:

$\frac{x+20}{3}=y$ , or to write it in slope-intercept form, like the function you started with:

$y=\frac{1}{3}x+\frac{20}{3}$

This is also a line, with a slope of 1/3 and a y-intercept of +20/3

Now, replacing:

$A^{-1}(n)=\frac{1}{3}n+\frac{20}{3}$

That is how to write the inverse using function notation. The little -1 as an exponent tells us that this is the inverse of the function A(n).

$(x^y)^z=x^y^z$

$b^4^*^3$

Then, multiply by the numbers from left to right.

$4*3=12$

ANSWER ASAP ITS FOR FINALS

Roman55 [17]

Answer:

9. 66°

10. 44°

11. $2\sqrt{7}$

12. $2\sqrt{3}$

13. 27.3

14. 33.9

15. 22°

16. 24°

Step-by-step explanation:

9. Add 120 + 80 (equals 200) and subtract that from 360 (Because all angles in a quadrilteral add to 360°), this equals 160. Plug the same number in for both variables in the two other angle equations until the two angles add to 160. For shown work on #9, write:

120 + 80 = 200

360 - 200 = 160

12(5) + 6 = 66°

19(5) - 1 = 94°

94 + 66 = 160

10. Because the two sides are marked as congruent, the two angles are as well. This means the unlabeled angle is also 68°. The interior angles of a triangle always add to 180°, so add 68+68 (equals 136) and subtract that from 180, this equals 44. For shown work on #10, write:

68 x 2 = 136

180 - 136 = 44

11. Use the Pythagorean theorem (a² + b² = c²) (Make sure to plug in the hypotenuse for c). Solve the equation. For shown work on #10, write:

a² + b² = c²

a² + 6² = 8²

a² + 36 = 64

a² = 28

a = $\sqrt{28}$

a = $2\sqrt{7}$

12. (Same steps as #11) Use the Pythagorean theorem (a² + b² = c²) (Make sure to plug in the hypotenuse for c). Solve the equation. For shown work on #11, write:

a² + b² = c²

a² + 2² = 4²

a² + 4 = 16

a² = 12

a = $\sqrt{12}$

a = $2\sqrt{3}$

13. Use SOH CAH TOA and solve with a scientific calculator. For shown work on #13, write:

Sin(47°) = $\frac{20}{x}$

x = 27.3

14. Use SOH CAH TOA and solve with a scientific calculator. For shown work on #14, write:

Tan(62°) = $\frac{x}{18}$

x = 33.9

15. Use SOH CAH TOA and solve with a scientific calculator. For shown work on #15, write:

cos(θ) = 52/56

θ = cos^-1 (0.93)

θ = 22°

16. (Same steps as #15) Use SOH CAH TOA and solve with a scientific calculator. For shown work on #16, write:

sin(θ) = 4/10

θ = sin^-1 (0.4)

θ = 24°

Good luck!!

If cos x=1/2 and 90°

Talja [164]

When I factor[ 2cos (square) - 5cos -3], I get (2cos + 1)(cos - 3). 2cos + 1 = 0, 2cos = -1, cos = -0.5,. Using inv cos on calculator, I get 120 degree related angle.
