1. What would the polynomial x + 7 – 4x^3 be written as in standard form?

5 0

Hello there!

The only thing we need to do to get this polynomial in standard form is rearrange the terms!

x+7-4x^3
-4x^3+x+7 is the polynomial written in standard form. Remember to keep track of the negatives!

The GCF of the polynomial
24x^5+18x^9 is...
6x^5
Because it is the greatest term that goes into both 24x^5 AND 18x^9!
This will end up helping you factor later on.
6x^5(4+3x^4)

I really hope this helps!
Best wishes :)

X=3

X/-3 = -1 ,Leave X by itself so multiply by -3 on both sides.

X = -1*-3

X = 3, negative times negative equals positive.

8. A substance has a half life of 2.347 minutes.

mina [271]

Answer:

a.) 4 half lives have passed

b) 9.388 minutes

Step-by-step explanation:

Formula for exponential growth / decay is given as:

$A=A_0b^{\frac{t}{c}}$

Where $A$ is the final population

$A_0$ is the initial population

$b$ is the growth factor

$c$ is the time taken for the growth 'b'

$t$ is the amount of time

Here, we are given that:

$A$ = 6. 9 grams

$A_0$ = 110.4 grams

$b = \dfrac{1}{2}$

$c = 2.347$ min

To find:

a.) Number of half lives taken for the decay.

b.) Total time in the decay.

Solution:

a.) Number of half lives taken for the decay is nothing but equal to $\frac{t}{c}$ .

Putting the values in the formula, we get:

$6.9=110.4\times \frac{1}2^{\frac{t}{c}}\\\Rightarrow 6.9=110.4\times 0.5^{\frac{t}{c}}\\\Rightarrow 0.0625=0.5^{\frac{t}{c}}\\\Rightarrow \dfrac{t}{c} =4$
