Zero and negative exponentswrite in simplest for without zero or negative exponents- 17 ⁰

Valentin [98]

$-17^0=(-17)^0=1$ $\begin{gathered} (-2)^2\times(-2)^{-5}=(-2)^{2-5} \\ =(-2)^{-3} \\ =\frac{1}{(-2)^3} \\ =\frac{1}{-8} \end{gathered}$

Thus, the final answers are 1 and -1/8.

How many students were asked? How do you know? Find the median for these data.

kkurt [141]

Answer:

a=10 students because there are 10 answers.

b=5

Step-by-step explanation:

a=10 students because there are 10 answers.

b, you need to list the numbers all out and rearrange them from smallest to largest.

0, 0, 1, 2, 3, 7, 9, 10, 13, 15

The median means the middle which is 3 and 7

Because we have two numbers, we need to find the middle number of 3 and 7 which is 5

Find the sum of the geometric series for which a = 160, r = 0.5, and n = 6.

harina [27]

$\\ \sf\longmapsto S_n=\dfrac{a(1-r^n)}{1-r}$

$\\ \sf\longmapsto S_n=\dfrac{160(1-0.5^6)}{1-0.5}$

$\\ \sf\longmapsto S_n=\dfrac{160(1-0.015625)}{0.5}$

$\\ \sf\longmapsto S_n=\dfrac{160(0.984378)}{0.5}$

$\\ \sf\longmapsto S_n=80(0.984378)$

$\\ \sf\longmapsto S_n=78.75$

Factorise: 4x squared - 9y squared

kicyunya [14]

Here is your great answer Simplifying
4x2y + 12xy2 + 9y3

Reorder the terms:
12xy2 + 4x2y + 9y3

Factor out the Greatest Common Factor (GCF), 'y'.
y(12xy + 4x2 + 9y2)

Factor a trinomial.
y((2x + 3y)(2x + 3y))

Final result:
y(2x + 3y)(2x + 3y)
