Answer:

  • k(x) = 2x
  • k(x) = 2x -7
  • k(x) = 2x -1
  • k(x) = 2x -8

Step-by-step explanation:

Vertical translation adds the amount of upward translation to the value of the function. Upward translation by 'v' units will make the new function ...

  k(x) = f(x) +v

__

We assume your f(x) is 2x -3.

<u>Up 3 units</u>

  k(x) = f(x) +3 = 2x -3 +3

  k(x) = 2x

<u>Down 4 units</u>

  k(x) = f(x) -4 = 2x -3 -4

  k(x) = 2x -7

<u>Up 2 units</u>

  k(x) = f(x) +2 = 2x -3 +2

  k(x) = 2x -1

<u>Down 5 units</u>

  k(x) = f(x) -5 = 2x -3 -5

  k(x) = 2x -8

Help please with question 5-8, show the solution
ludmilkaskok [199]

For each of these problems, remember SOH-CAH-TOA.

Sine = opposite/hypotenuse

Cosine = adjacent/hypotenuse

Tangent = opposite/adjacent

5) Here we are looking for the cosine of the 30 degree angle. Cosine uses the adjacent side to the angle over the hypotenuse. Therefore, cos(30) = 43/50.

6) We have an unknown side length, of which is adjacent to 22 degrees, and the length of the hypotenuse. Since we know the adjacent side and the hypotenuse, we should use Cosine. Therefore, our equation to find the missing side length is cos(22) = x / 15.

7) When finding an angle, we always use the inverse of the trigonometry function we originally used. Therefore, if sin(A) = 12/15, then the inverse of that would be sin^-1 (12/15) = A.

8) We are again using an inverse trigonometry function here. We know the hypotenuse, as well as the side adjacent to the angle. Therefore, we should use the inverse cosine function. Using the inverse cosine function gives us cos^-1 (9/13) = 46 degrees.

Hope this helps!

This year, for the spring musical, the Drama Club sold 150% of the number of tickets they sold last year. Last year, the club so
babunello [35]

Answer:

C. 342

Step-by-step explanation:

This year, 150% of last year's tickets were sold.

Last year, 228 tickets were sold.

150% as a fraction is 150/100

To find the amount of tickets sold this year, we take the 150/100 and multiply it by 228:

150/100*228= 342 tickets

76 19 in ratio simplest form
Nata [24]
Putting the two numbers together in fraction form of a ratio, we have 76/19. We know that something multiplied by 19 will equal to 76.

When we try to multiply 4 and 19 together, we have our nice answer 76. We then replace out values in the original ratio, in which we get the final answer of 4:1, 4/1, or 4 to 1.

Write down the first three terms of the sequence whose nth term is given by 2n-5
likoan [24]

Answer:

- 3, - 1, 1

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into the formula

a₁ = 2(1) - 5 = 2 - 5 = - 3

a₂ = 2(2) - 5 = 4 - 5 = - 1

a₃ = 2(3) - 5 = 6 - 5 = 1

The first 3 terms are - 3, - 1, 1
