-2/1 I did this is math class , we’re on this unit to,

Explanation
Saying it’s a negative number because it is pointing in a left word position, you have to go down twice and over once to find the exact point where the line crosses over a point on the graph, and there you will get -2/1

The amount ofmoney is in the ratio 8:3 if the first amount is 9.92 what is the second amount?

BARSIC [14]

Answer:

The second amount is 3.72

Step-by-step explanation:

Given

$First : Second = 8 : 3$

$First = 9.92$

Required

Find Second

$First : Second = 8 : 3$

Substitute 9.92 for First

$9.92: Second = 8 : 3$

Express as fraction

$\frac{Second}{9.92} = \frac{3}{8}$

Multiply both sides by 9.92

$9.92 * \frac{Second}{9.92} = \frac{3}{8}*9.92$

$Second = \frac{3}{8}*9.92$

$Second = 3.72$

What is the simplified form of the following expression? (5 points)

jek_recluse [69]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Simplify ⇨ (n⁵)(n²)

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\tt \: ( n ^ { 5 } ) ( n ^ { 2 } )$

To multiply powers of the same base, add their exponents.

$\tt \: n ^{5 + 2} \\$

Add 5 and 2 to get 7.

$= \boxed {\boxed{\bf \: {n}^{7} }}$

The first option n⁷ is the correct answer.

Select the correct answer from the drop down menu. with references to the figure, sin x =

Lubov Fominskaja [6]

Answer:

.894

Step-by-step explanation:

First thing to do is to solve for the height of the triangle, BD. That's easy. We have the length of the hypotenuse and the base, so Pythagorean's Theorem gives us that the height is 8.003255588 which rounds nicely to 8. Now you have to call on the fond memories you have of the geometric mean in right triangles to solve the rest. For the sin of x you need the hypotenuse of that smaller right triangle on the left, side AB. First let's use geometric mean to find AD. The formula for that, now that we know the height, is

$BD^2=(AD)(DC)$

Filling that in with numbers we have

$8^2=(AD)16$ and

64 = 16(AD). Solve for AD to get that AD has a length of 4. Now we know two of the three sides in that smaller triangle on the left and can solve for the hypotenuse.

$8^2+4^2=c^2$ and

$64+16=c^2$ so

c=√80 which simplifies to 4√5. That means that the sin ratio for x is

$\frac{8}{4\sqrt{5} }$

which divides out to .894
