To find f(5),we put 5 into x

f(5) = -2(5) + 2
= -10+2
=-8

Thus,f(5) = -8

Given that e= 2i – 5j + 9k and f= 8i + 15j + k, find 3f – 2e.
ipn [44]

Plug in "8i + 15j + k" for "f", and "2i – 5j + 9k" for "e"

3(8i + 15j + k) - 2(2i – 5j + 9k)

Distribute 3 to (8i + 15j + k) & - 2 to (2i – 5j + 9k)

3(8i + 15j + k) = 24i + 45j + 3k

-2(2i - 5j + 9k) = -4i + 10j - 18k

-------------------------------------------------------------------------------------------------------------------

Simplify. Combine like terms

24i - 4i + 45j + 10j + 3k - 18k

(24i - 4i) + (45j + 10j) + (3k - 18k)

20i + 55j - 15k is your answer, or (C)

-------------------------------------------------------------------------------------------------------------------

hope this helps

What does AC=?<br> Round your answer to the nearest hundredth. <br><br> Please help
faltersainse [42]

Answer: About 3.06

Step-by-step explanation:

  We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

  Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

      cos(θ) = \frac{adjacent}{hypotenuse }

      cos(40) = \frac{x}{4}

      0.766 ≈ \frac{x}{4}

      3.06 ≈ x

      x ≈ 3.06

Thirty seven divided by nine
Sunny_sXe [5.5K]

Answer:

4.11 (rounded to the hundredth place, the actual answer is 4.1(with the one repeating))

Step-by-step explanation:

To solve 37 divided by 9 you have to do long division or you can use a handheld calculator.

To solve it through long division,

9 can go into 3 zero times

9 can go into 37 four times though

9*4 is 36

So subtract 36 from 37, leaving 1.

9 can go into 1 zero times.

Add a zero behind the one and 9 can go into 10 once.

The pattern continues forever, making the answer 4.1(with the one repeating)

or 4.11 (rounded to the hundredth place)

If you need anymore clarification I can certaintly help.
