What is the simplified form of the expressions? a. −6a2b−1 b. 5/y−3

joja [24]

Given:

The expressions are

$-6a^2b^{-1}$

$\dfrac{5}{y^{-3}}$

To find:

The simplified form of each expression.

Solution:

We have,

$-6a^2b^{-1}$

$=-6a^2(\dfrac{1}{b})$ $[\because x^{-n}=\dfrac{1}{x^n}]$

$=-\dfrac{6a^2}{b}$

Therefore, the simplified form of $-6a^2b^{-1}$ is $-\dfrac{6a^2}{b}$ .

We have,

$\dfrac{5}{y^{-3}}$

$=\dfrac{5}{\dfrac{1}{y^3}}$ $[\because x^{-n}=\dfrac{1}{x^n}]$

$=5\times \dfrac{y^3}{1}$

$=5y^3$

Therefore, the simplified form of $\dfrac{5}{y^{-3}}$ is $5y^3$ .

MATH: Composition of two functions...help needed with this problem

Evgesh-ka [11]

The equation of Q(n) is $Q(n) = \frac89 * (88n + 23)$

<h3>How to determine the formula of Q(n)?</h3>

The functions are given as:

$R(d) = \frac89 d$

$P(n) = 88n + 23$

From the question, we understand that:

d = P(n)

This means that:

d = 88n + 23

Substitute d = 88n + 23 in R(d)

$R(n) = \frac89 * (88n + 23)$

Also, from the question

Q(n) = R(n)

So, we have:

$Q(n) = \frac89 * (88n + 23)$

Hence, the equation of Q(n) is $Q(n) = \frac89 * (88n + 23)$

I need to find the zeros to these two problems and I have no idea how

Iteru [2.4K]

If you have a graphing calculator just put in the equation in 'y=' (not the i equation), and then go to 2nd trace and see where the y=0, those numbers under the x column are the zeros. For the first one, the zeros are: -1, .5, and 2.8. For the second question the zeros are: -3 and about 1.9. The zeros with a decimal are estimations.

Show your work with long division please

Naya [18.7K]

Answer:

Step-by-step explanation:

7/11 = no, add 0

70/11 = 6, so 0.6, remainder is 4, add 0

40/11 = 3, so 0.03, remainder is 7, add 0

70/11 = 6... and it goes on
