You didn't specify the topic so I will solve it in 3 topics
solving for a, you take roots of both sides and solve a=18,-18
using the quadratic formula, solve the equation for aa by finding aa, bb, and ccof the quadratic then applying the quadratic formula.

a=±√321a=±321

a≈17.91647286,−17.91647286


for factoring, Factor and set each factor equal to zero.

a=√321,−√321a=321,-⁢321

a≈17.91647286,−17.91647286

342 = a²

switch sides:

for x² = f(a) the solutions are x = √ f(a)   and - √ f(a)

therefore:

√ 342 = 18

-√ 342 = - 18

a = 18  and a = - 18

hope this helps!

<h3>What is the IRR for each of these projects?</h3>

using an excel spreadsheet and the IRR function:

Project A's IRR = 28.3%

Project B's IRR = 25.7%

(b) If you apply the IRR decision rule, which project should the company accept?

Project A (its IRR is higher)

Requirement 2:

(a) Assume the required return is 14 percent. What is the NPV for each of these projects?

using an excel spreadsheet and the NPV function:

Project A's NPV = $14,921.37

Project B's NPV = $15,156.64

(b) Which project will you choose if you apply the NPV decision rule?

Project B (its NPV is higher)

What other angle between O and 360 degrees has the same TAN value as 71
atroni [7]

Answer:

<u>-289 degrees</u>

Step-by-step explanation:

You are looking for what is called  <u>Coterminal Angles</u>.

To find a coterminal angle between 0 and 360 you <u>add or subtract</u> 360.

  1. In this case, we subtracted 360 from 71
  2. 71 - 360 = -289
  3. tan(-289) = 2.90
  4. If  TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.

Hope this helps!! Please mark Brainliest!!!
