Answer:

16,876,789. 82364 ≈ 82,000

Step-by-step explanation:

Let's go through this Step by Step.

$3847 * 4387 =\\3847 * 7 = 26929\\3847 * 80 = 307,760\\3847 * 300 = 1,154,100\\3847 * 4000 = 15,388,000$

Now let's go through the Addition.

$26929 + 307,760 = 334,689\\334,689 + 1,154,100 = 1,484,789\\1,484,789 + 15,388,000 = 16,872,789$

Now, we round 82364 to the nearest thousand.

The nearest thousand is 2000. so the answer to this one would be 82000.

hope this helps.

Answer:

204.904922053, or 204.904.

Step-by-step explanation:

3847/82,364 times 4387.

So, we are gonna do 3847 times 4387. Which gives us 16,876,789.

Now, our problem would look like 16,876,789/82,364.

Now, we are gonna do 16,876,789 divided by 82,364.

Which gives us the answer of 204.904922053, or 204.904.

So, ur final answer will be 204.904922053, or 204.904.

Hope this helps!

Trina borrowed $460 from a friend. Her friend charged her 5% simple annual interest.

Margarita [4]

The interest of 3 years
=(460×5%)×3

Trina will owe her friend
=460+(460×5%) ×3
=460+23×3
=460+69
=$529
hope it helps!

pav-90 [236]

$e\cdot e^x -e^{-2}=-2$

$\implies e^{x+1}=e^{-2}-2$

note that RHS is negative. (because e with negative exponent is less than 1)

and LHS is always positive.

so there cannot be any solution

Use the given information to find the exact value of the trigonometric function

eimsori [14]

$\begin{gathered} \csc \theta=-\frac{6}{5} \\ \tan \theta>0 \\ \cos \frac{\theta}{2}=\text{?} \end{gathered}$

Half Angle Formula

$\cos \frac{\theta}{2}=\pm\sqrt[\square]{\frac{1+\cos\theta}{2}}$ $\tan \theta>0\text{ and csc}\theta\text{ is negative in the third quadrant}$ $\begin{gathered} \csc \theta=-\frac{6}{5}=\frac{r}{y} \\ x^2+y^2=r^2 \\ x=\pm\sqrt[\square]{r^2-y^2} \\ x=\pm\sqrt[\square]{6^2-(-5)^2} \\ x=\pm\sqrt[\square]{36-25} \\ x=\pm\sqrt[\square]{11} \\ \text{x is negative since the angle is on the 3rd quadrant} \end{gathered}$ $\begin{gathered} \cos \theta=\frac{x}{r}=\frac{-\sqrt[\square]{11}}{6} \\ \cos \frac{\theta}{2}=\pm\sqrt[\square]{\frac{1+\cos\theta}{2}} \\ \cos \frac{\theta}{2}is\text{ also negative in the 3rd quadrant} \\ \cos \frac{\theta}{2}=-\sqrt[\square]{\frac{1+\frac{-\sqrt[\square]{11}}{6}}{2}} \\ \cos \frac{\theta}{2}=-\sqrt[\square]{\frac{\frac{6-\sqrt[\square]{11}}{6}}{2}} \\ \cos \frac{\theta}{2}=-\sqrt[\square]{\frac{6-\sqrt[\square]{11}}{12}} \\ \\ \end{gathered}$

Answer:

$\cos \frac{\theta}{2}=-\sqrt[\square]{\frac{6-\sqrt[\square]{11}}{12}}$

Checking:

$\begin{gathered} \frac{\theta}{2}=\cos ^{-1}(-\sqrt[\square]{\frac{6-\sqrt[\square]{11}}{12}}) \\ \frac{\theta}{2}=118.22^{\circ} \\ \theta=236.44^{\circ}\text{ (3rd quadrant)} \end{gathered}$

Also,

$\csc \theta=\frac{1}{\sin\theta}=\frac{1}{\sin (236.44)}=-\frac{6}{5}\text{ QED}$

The answer is none of the choices
