Answer:

D) 0.5x^3y + 4x^2 y^2 - 2xy^3

Step-by-step explanation:

Set up an equation to model the situation,

(-0.5xy)(x^2 + 8xy - 4y^2)

Distribute, multiply each term in the parenthesis with the term outside of the parenthesis. Don't forget the laws of exponents, when one multiplies two exponents, with the same base, then one adds the two exponents. A number with no exponential term is two the first degree meaning that it is to the power of one.

-0.5x^3 y - 4x^2 y^2 + 2xy^3

If tan x° = a divided by 4 and cos x° = 4 divided by b what is the value of sin x°? (1 point) \
Rudiy27

Answer:

Sin x = a / b.

Step-by-step explanation:

The opposite side =a and the adjacent side = 4 (because tan x = a/4.

Cos x = 4/b so the hypotenuse = b ( because  Cos = adjacent /hypotenuse.

So sin x = opposite /hypotenuse = a / b.

Nadya [2.5K]

Susan's monthly payment will be $117.93.

We have Susan take out a personal loan for $3,500 at an interest rate of 13% compounded monthly.

P=3500

r=30%

t=3

<h3>What is the amortization formula?</h3>

A = \frac{P(\frac{r}{12} )}{(1 -(1 +r/12)^{(-12t)}}

Where A is the payment,

P= principal,

r =the annual interest rate

t is the number of years.

use the given value in the formula we get

A = \frac{3500(0.13/12)}{(1 -(1 +0.13/12)^{-36} }

A=117.9288

A= 117.93

Susan's monthly payment will be $117.93.

bija089 [108]

Answer:

<h2>The answer is - 16</h2>

Step-by-step explanation:

<h3>b(n) =  - 1 ({2})^{n - 1}</h3>

where

n is the number of terms

From the question since we are finding the 5th term

n = 5

Substitute the value into the above formula and solve

We have

b(5) =  -  1({2})^{5 - 1}  \\  =  - 2 ^{4}

We have the final answer as

<h3>- 16</h3>

Hope this helps you
