A variable can allow you to  guess and test.  If you had a definite answer, there would be no need to guess and test.  However, you could still use a formula to figure the answer.

Which statement is true about ∠JXM and ∠NXP? a.∠JXM and ∠NXP are complementary. b.∠JXM and ∠NXP are vertical. c.∠JXM and ∠NXP ar
xenn [34]

Answer:

Incomplete questions

Check attachment for correct question.

The correct answer is

A. ∠JXM and ∠NXP are complementary

step explanation:

line JP is a straight line and sum of angle on a straight line is 180°.

There are three angles on this straight line JP which are ∠JXM, ∠NXP and ∠MXN

Note: from the attachment, it is shown that ∠MXN is a right angle i.e. 90°.

Then, sum of angle on this line is 180°.

∠JXM + ∠NXP + ∠MXN = 180°

∠JXM + ∠NXP + 90° = 180°

∠JXM + ∠NXP = 180° — 90°

∠JXM + ∠NXP = 90°

From the definition of complementary angles : Two Angles are said to Complementary if their sum is 90° (a Right Angle).

They don't have to be next to each other, just so long as the sum is 90 degrees.

Then, since ∠JXM + ∠NXP add up to 90°, it shows that ∠JXM and ∠NXP are complementary

So the correct option is A

D. 
slope = -3
passing thru(4,3)
 y = mx + b
3 = -3(4) + b
b = 15

equation
y = -3x + 15

E.
(4,5)(6,9)
slope = (9-5)/(6-4) = 4/2 = 2
passing thru (4,5)(6,9)
y = mx + b
5 = 2(4) + b
b = -3

equation
y = 2x - 3

Suppose Amanda wants to have $800,000 in her IRA at the end of 30 years. She chooses to invest in an annuity that pays
VARVARA [1.3K]

Her IRA interest at the end of 30 years is mathematically given as

Interest= 438,765.56

<h3> IRA interest </h3>

Question Parameters:

  • N = 30
  • PV = 0
  • rate = 5%
  • FV = 800,000

Generally the equation for the payment function on excel is mathematically given as

A=PMT(rate, nper, pv, [fv], [type])

Therefore, inputting our functions

A=PMT(rate, nper, pv, [fv], [type])

where

A=PMT(5%, 30, 0, [800000], [])

A = 12,041.1481

Hence

interest = 800,000 - 30*12,041.1481

Interest= 438,765.56
