Shkiper50 [21]

p(1+r/n)^(r times n)

P is your start amount

R is rate as a decimal 5% would be 0.05

t is time (years)

n is the number of time compounded , weekly would be 52 times a year.    

2300(1 + (0.0212/52))^(52 times 7)

What is the following answer the equation 275 4/5 + 20.2 <br> and what is 275 4/5 - 20.2
Lady_Fox [76]

Answer: 275 + \frac{4}{5} +20.2 = 296

275 + \frac{4}{5} - 20. = 255.

Step-by-step explanation:

275 + \frac{4}{5}  + 20.2 (

= 275 + 0.8 + 20.2

= 275.8 + 20.2 = 296

275 + \frac{4}{5} - 20.2

= 5 + 0.8 - 20.2 ( \frac{4}{5} = 0.8)

=  275.8 - 20.2 = 255.

Write an equation in slope-intercept form of the line that passes through -9, 5 and -3,3 .
stich3 [128]

Answer:

y = -1/3x + 2

Step-by-step explanation:

First, find the slope using rise over run: (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(3 - 5) / (-3 + 9)

-2 / 6

= -1/3

Plug in a given point and the slope into y = mx + b, and solve for b:

y = mx + b

3 = -1/3(-3) + b

3 = 1 + b

2 = b

Plug in the slope and y intercept into y = mx + b

y = -1/3x + 2

So, the equation is y = -1/3x + 2

Option B

3 x\sqrt{2} x is the choice equivalent to \sqrt{6} x^{2} \cdot \sqrt{3} x

<em><u>Solution:</u></em>

Step 1:

When we multiply two roots i.e. \sqrt{6} x^{2} and \sqrt{3} x the values are multiplied and still kept inside the root.

So \sqrt{6} x^{2} × \sqrt{3} x = \sqrt{6} x^{2} \times 3 x.

Step 2:

We then multiply the values in the root.

\sqrt{6} x^{2} \times 3 x = \sqrt{18 x^{3}}

Step 3;

We take the values out of the root by splitting up the value.

{18 x^{3}} = (9 \times 2)\left(x^{2} \times x\right)

\sqrt{9}=3 and \sqrt{x^{2}}=x

So \sqrt{18 x^{3}} = \sqrt{9} \times 2 \times x^{2} \times x

When we take values out of the root, we replace it with the square-rooted value on the outside.

\sqrt{18 x^{3}} = 3 x \sqrt{2 x}.

Thus option B is correct
