Answer:

$2x(x + 1) - 2 = 2(x - 3)(x + 3) \\ = > 2 {x}^{2} + 2x - 2 = 2( {x}^{2} - {3}^{2} ) \\ = > 2 {x}^{2} + 2x - 3 = 2 {x}^{2} - 2(9) \\ = > 2 {x}^{2} + 2x - 3 \: is \: not \: equal \: to \: 2 {x}^{2} - 1$

qwelly [4]

Well if it is -20 then A but if it was just 20 it would be C all you have to do is divide
$300 \div 15$

Given right triangle ABC. To the nearest degree, find the measure of angle B.

DedPeter [7]

Answer:

Step-by-step explanation:

We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.

sin(B) = side opposite / hypotenuse:

$sin(B)= \frac{ 4.8}{ 5.1}$ so

sin(B) = .9411764706

Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:

$sin^{-1 ($

Enter that decimal after the open parenthesis and hit "enter" to get

B = 70.25 or 70°

MATHEMATICS<br> Evaluate (0.110 two)³ expressing your answer in base ten.

zysi [14]

Evaluating (0.110 two)³ in base ten is (343/512) ten

The question has to do with number base

<h3>What is number base?</h3>

A number base is a system of numbering used to represent numbers.

<h3>How to evaluate (0.110 two)³ in base ten.</h3>

Since we have (0.110 two)³,we desire to convert 0.110 two to base ten.

So, converting 0.110 two to base ten, following the procedure, we have that

0.110 two = 0 × 2⁰ + 1 × 2⁻¹ + 1 × 2⁻² + 1 × 2⁻³

= 0 × 2⁰ + 1 × 1/2¹ + 1 × 1/2² + 1 × 1/2³

= 0 × 1 + 1 × 1/2 + 1 × 1/4 + 1 × 1/8

= 0 + 1/2 +1/4 + 1/8

= (4 + 2 + 1)/8

= 7/8

So, thus 0.110 two = (7/8) ten

Thus we see that (0.110 two)³ = (7/8)³ ten

= (343/512) ten

So, expressing (0.110 two)³ in base ten is (343/512) ten

Find the value of $1000 deposited for 10 years in an account paying 6% annual interest compound

Romashka [77]

Answer:

You have to use the formula for compound interest which is: A=P(1+r/n)^nt

The Givens info is:

A=?

P=1000

r= 6% = 0.06 (convert into decimal)

n=12(# of interest periods: since it is monthly n=12)

t=10

Now your formula should look like this:

A= 1000*(1+(0.06/12))^12*10

A=1000*(1.005)^120

A=1000*(1.819396734)

A=$1819.40
