Answer:

You put 8i^2 instead of 12i^2. You multiply -6i by -2i which equal -12i^2

Step-by-step explanation:

-7 + 6i - 14i+ 12i^2

-7 - 8i - 12

-19 - 8i

Helen wrote the following facts to try to show that division by 0 results in 0. Explain her error.

earnstyle [38]

Helen should of put 0 first, because if you're gonna divide, you need to put the product first, then one of the factoes.

So instead it should be 0÷(-7)=0

A 6.50% coupon bond with 18 years left to maturity is offered for sale at $1,035.25. What yield to maturity [interest rate] is t

Basile [38]

Answer:

The yield to maturity is 6.3974%

Step-by-step explanation:

The computation of the yield to maturity is as follows

Given that

NPER = 18 × 2 = 36

PMT = $1,035.25 × 6.50% ÷ 2 = $33.65

PV = $1,035.25

FV = $1,000

The formula is shown below:

=RATE(NPER;PMT;-PV;FV;TYPE)

The present value comes in negative

AFter applying the above formula, the yield to maturity is

= 3.1987% × 2

= 6.3974%

Hence, the yield to maturity is 6.3974%

Plz HELP! WILL GIVE BRAINLIEST!<br><br>1. Consider the picture below. Find the measure of ∠CEA.

pashok25 [27]

Answer:

103°

Step-by-step explanation:

The marked angles have the same measure, so ...

14x+7 = 12x +17

2x = 10 . . . . . subtract 12x+7

x = 5 . . . . . . . divide by 2

(14x +7)° = 77°

∠CEA is supplementary to the marked angles:

∠CEA = 180° -77°

∠CEA = 103°
