Answer:

11.2

Step-by-step explanation:

The Pythagorean theorem means that in a right triangle the hypotenuse (the longest side, opposite the right angle) squared equals the sum of the squares of the other two sides.

Therefore

15^{2} -10^2=b^2

or

225-100=b^2=125

Now, all you have to do is find the square root of 125

\sqrt[2]{125} = 11.2

Pythagorean Theorem Formula: a^2 + b^2 = c^2

We are solving for b of the triangle.

Steps to solve:

10^2 + b^2 = 15^2

~Solve for the exponents

100 + b^2 = 225

~Subtract 100 to both sides

100 - 100 + b^2 = 225 - 100

~Simplify

b^2 = 125

~Take the square root of both sides

√b^2 = √125

~Simplify

b = 11.1803398875

~Round to the nearest tenth

11.1803398875 → 11.2

Hence, the length of "b" is <u>11.2</u>

Best of Luck!

\begin{gathered} a)P=30000(1+0.05)^n \\ b)\$62,367.00 \end{gathered}

1) Iteration means a repetition of a rule.

a)

Considering that we have the following data:

Rate of increase: 5% per year

-

2) Then we can write out the following:

P=30000(1+0.05)^n

Plugging into n, the number of years we'll have:

Profits: $30,000 1st year

P: $31.500 2nd year

$33075 3rd year

(...) (...)

b) Since we want to know the predicted profit 15 years from the first year, then we can plug for that:

\begin{gathered} P=30000(1+0.05)^{15} \\ P=\$62,367.00 \end{gathered}

Note that we have plugged into n, n=15 years. Since the first year was $30,000 the profits.

Express the quotient of z1 and z2 in standard form given that <img src="https://tex.z-dn.net/?f=z_%7B1%7D%20%3D%20-3%5Bcos%28%5C
Lesechka [4]

Answer:

Solution : -\frac{3}{4}-\frac{3}{4}i

Step-by-step explanation:

-3\left[\cos \left(\frac{-\pi }{4}\right)+i\sin \left(\frac{-\pi \:}{4}\right)\right]\:\div \:2\sqrt{2}\left[\cos \left(\frac{-\pi \:\:}{2}\right)+i\sin \left(\frac{-\pi \:\:\:}{2}\right)\right]

Let's apply trivial identities here. We know that cos(-π / 4) = √2 / 2, sin(-π / 4) = - √2 / 2, cos(-π / 2) = 0, sin(-π / 2) = - 1. Let's substitute those values,

\frac{-3\left(\frac{\sqrt{2}}{2}-\frac{\sqrt{2}}{2}i\right)}{2\sqrt{2}\left(0-1\right)i}

=-3\left(\frac{\sqrt{2}}{2}-\frac{\sqrt{2}}{2}i\right) ÷ 2\sqrt{2}\left(0-1\right)i

= 3\left(-\frac{\sqrt{2}i}{2}+\frac{\sqrt{2}}{2}\right) ÷ -2\sqrt{2}i

= \frac{3\left(1-i\right)}{\sqrt{2}}÷ 2\sqrt{2}i = -3-3i ÷ 4 = -\frac{3}{4}-\frac{3}{4}i

As you can see your solution is the last option.
