Simplify completely.
Arte-miy333 [17]

Answer:

\large\boxed{\sqrt{27y^8}=3y^4\sqrt3}

Step-by-step explanation:

\sqrt{27y^8}=\sqrt{9\cdot3\cdot y^{4\cdot2}}\\\\\text{Use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b},\ (a^n)^m=a^{nm}\ \text{and}\ \sqrt{a^2}=a\\\\=\sqrt9\cdot\sqrt3\cdot\sqrt{(y^4)^2}=3\cdot\sqrt3\cdot y^4=3y^4\sqrt3

Find the illegal values of c in the multiplication statement c^2-3c-10/c^2+5c-14 times c^2-c-2/c^2-2c-15
Citrus2011 [14]

Answer: c ≠ {-7, -3, 2, 5}

<u>Step-by-step explanation:</u>

  \frac{c^{2} - 3c - 10}{c^{2} + 5c - 14} * \frac{c^{2} - c - 2}{c^{2} - 2c - 15}

= \frac{(c - 5)(c + 2)}{(c + 7)(c - 2)} * \frac{(c - 2)(c + 1)}{(c - 5)(c +3)}

restrictions:

c + 7 ≠ 0           c - 2 ≠ 0          c - 5 ≠ 0          c + 3 ≠ 0

    c ≠ -7                 c ≠ 2               c ≠ 5                c ≠ -3

online price is 130% or original
superstore price is 140% or original
the difference bewteen them is 140-130=10% of the original price

A. 1.3 times 160=208=online
1.4 times 160=224=superstore

B. difference is 224-208=16=10% of 160
it is 10% of the original price




A. online=$208
superstore=$224

What are the zeros of the quadratic function? f(x)=3x2−300 Enter your answers in the boxes.
nata0808 [166]
Hi there!

We can find the zeros of a function by solving f(x) = 0. We find the following:

3 {x}^{2} - 300 = 0
Add 300 to both sides.

3 {x}^{2} = 300
Divide by 3.

{x}^{2} = 100
Take the root and minus root of both sides.

x = \sqrt{100} = 10 \\ or \\ x = - \sqrt{100} = - 10

Therefore, the zeros are
x = 10 and x = -10.

~ Hope this helps you!
