Simplify (-3c^-3w^5)^3<br> A -9w^8<br> B. -27cw^8<br> C. w^15/27c^9<br> D.-27w^15/c^9
kenny6666 [7]

Answer:

\large\boxed{D.\ \dfrac{-27w^{15}}{c^9}}

Step-by-step explanation:

(-3c^{-3}w^5)^3\qquad\text{use}\ (ab)^n=a^nb^n\\\\=(-3)^3(c^{-3})^3(w^5)^3\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=-27c^{-3\cdot3}w^{5\cdot3}=-27c^{-9}w^{15}\qquad\text{use}\ a^{-n}=\dfrac{1}{a^n}\\\\=-27\left(\dfrac{1}{c^9}\right)w^{15}=\dfrac{-27w^{15}}{c^9}

A polynomial function, f(x), has x-intercepts at (-6,0) and (2,0). What is one possible factor of f(x)? PLEASE GIVE STEPS
Mila [183]
Set
f
(
x
)
=
0
f(x)=0.
If the polynomial function is not given in factored form:
Factor out any common monomial factors.
Factor any factorable binomials or trinomials.
Set each factor equal to zero and solve to find the
x
x- intercepts.

Which polynomial is written in ascending order? t2 − t 4 t2 4 − t 4 t2 − t 4 − t t2
butalik [34]
In order to solve this, you have to look at the order for each of the variable terms. In this case t is your variablr
<span>4<span>t0</span>=4</span> exponent is 0. <span>−<span>t1</span>=−t</span> exponent is 1. <span>t2</span> exponent is 2. So you order them by exponents from least to greatest (ascending). <span><span>4−t+<span>t2</span></span></span>

Answer:

- \frac{25}{4}

Step-by-step explanation:

\frac{1}{2} -3 (\frac{1}{2} + 1)²

Calculate sum

\frac{1}{2} -3x (\frac{3}{2})²

To raise a fraction to a power raise numerator and denominator to that power

\frac{1}{2} -3 x \frac{9}{4}

Calculate product

\frac{1}{2} - \frac{27}{4}

Subtract fractions
