mylen [45]3 years ago

4 0

Answer: Option A. -4x^8

Step-by-step explanation:

The polynomial function given in the graph has 4 real roots. And because the graph falls to the left and right, it will have even order and negative leading coefficient.

So we have only one option that matches the required conditions, and i.e. option A.

What is the sum of the infinite geometric series?

12345 [234]

Answer:

- 288

Step-by-step explanation:

The n th term of a geometric series is

$a_{n}$ = a $r^{n-1}$

- 144 $(\frac{1}{2}) ^{n-1}$ is in this form

with a = - 144 and r = $\frac{1}{2}$

$S_{infinity}$ = $\frac{a}{1-r}$ = $\frac{-144}{1-\frac{1}{2} }$ = $\frac{-144}{\frac{1}{2} }$ = - 288

ALGEBRA 2 QUESTION URGENT HELP PLEASE!!

NARA [144]

Answer:

d. the quantity of negative twenty plus sixteen i all over forty one.

Step-by-step explanation:

We want to simplify the complex number:

$\frac{\sqrt{-16} }{(3-3i)+(1-2i)}$

We rewrite to obtain:

$\frac{\sqrt{16}\times \sqrt{-1} }{(3+1)+(-3i-2i)}$

Recall that: $\sqrt{-1}=i$ and $-1=i^2$

We simplify to get:

$\frac{4i}{4-5i}$

We rationalize to get:

$\frac{4i}{4-5i}\times\frac{4+5i}{4+5i}$

$\frac{4i(4+5i)}{(4-5i)(4+5i)}$

$\frac{16i+20i^2}{4^2+5^2}$

$\frac{16i-20}{16+25}$

$\frac{-20+16i}{41}$

The correct answer is D
