Step-by-step explanation:

i = interest 3% for 30 years

This is a simple dynamical system for whom the the solutions are given as

$S=R[\frac{(i+1)^n-1}{i}](i+1)$

putting values we get

S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)

= $98005.35

withdrawal of money takes place from one year after last payment

To determine the result we use the present value formula of an annuity date

$P = R\frac{1-(1+i)^{-n}}{i}{i+1}$

we need to calculate R so putting the values and solving for R we get

R= $6542.2356

Step-by-step explanation:

It appears that given geometrical shape is a HEXA-DECAGON or a 16 sided polygon.

Measure of one interior angle of hexa-decagon can be given as:

$\frac{(n - 2) \times 180 \degree}{n} \\ \\ = \frac{(16 - 2) \times 180 \degree}{16} \\ \\ = \frac{14 \times 45 \degree}{4} \\ \\ = \frac{7 \times 45 \degree}{2} \\ \\ = \frac{315 \degree}{2} \\ \\ = 157.5\degree \\$

Find the missing length. Round to the nearest tenth, If necessary.

ziro4ka [17]

Using the formula a² + b² = c² but reversing it to c² - b² = x² where x replaces the a for comprehension reasons

so this is the formula
c² - b² = x²

insert the numbers on the triangle in the picture
21² - 8² = 377

since 377 is squared and not the side length, we need to square root it to find x
√377 = 19.4~

Answer: x = 19.4

A student is 7 years old. If you triple the teachers age and add the student's age the answer is 163. How old is the teacher?

pogonyaev

Answer:

Step-by-step explanation:

We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:

$3x + 7 = 163$

We want to isolate the variable, so subtract 7 from both sides. This gives us:

$3x = 156$

Finally, we divide both sides by 3, giving:

$x=52$

So the teacher is 52 years old.

Hope this helps!
