Answer:

2\sqrt{2x} or 8x^2

Step-by-step explanation:

first you find the distance between P and O which is 4n (use the distance formula -- \sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)})

then find the distance between O and Q also using the distance formula; it gives you 4n

then find the hypotunuse by using the pythagorean theorem, a^2+b^2=c^2 which would be 4n^2+4n^2=hypotenuse and when you simplify it, you get 8x^2 and if you need it in radical form, it would be 2\sqrt{2x}

Answer:

Hypotenuse  = 4n \sqrt{2}

Step-by-step explanation:

Catethus1=4n

Catethus2=4n

Hypotenuse=?

Hypotenuse= \sqrt{{(catethus1)}^{2}  + {(catethus2)}^{2}} \:  = \sqrt{{(4n)}^{2}  + {(4n)}^{2}} \:  = 4n \sqrt{2}

Andrea has a savings account with $80 that earns 2% interest per
lianna [129]

Answer:

After 10 years, she will has $96 in her bank.

Step-by-step explanation:

It is given that Andrea's saving account is $80 and earns 2% interest per year as a <em>S</em><em>i</em><em>m</em><em>p</em><em>l</em><em>e</em><em> </em><em>I</em><em>n</em><em>t</em><em>e</em><em>r</em><em>e</em><em>s</em><em>t</em><em> </em>(Not Compounded). Using simple interest formula, Interest = (P×R×T)/100 where <em>P</em> is the <em>principal</em>, <em>R</em> is the <em>interest rate</em> and <em>T</em> is <em>number of years</em><em> </em>:

I =  \frac{p \times r \times t}{100}

P = $80

R = 2%

T = 10 years

I =  \frac{80 \times 2 \times 10}{100}

I =  \frac{1600}{100}

I = 16

It is given that the interest amount is $16. So the total amount she has after 10 years in the bank is $96 :

interest amount = $16

principal = $80

total = $16 + $80

= $96

Sarah works ar a shoe store. She earns a base salary of $1,500 per month, plus a 25% commission on the amount of shoe sales she
STatiana [176]

Answer:

Step-by-step explanation:

goal is 2,000 and she already makes 1,500

2,000-1,500 gives you the amount she needs to earn from shoe sales

she needs to earn 500 dollars with a 25% commision

25% can also be written as 25/100

for every $100 she makes, she gets $25 but she needs $500

100:25

we need the second number in the ratio to equal $500

500 divided by 25 is 20

20 x 100 : 25 x 20

2000: 500

ANOTHER WAY: 500 is 1/4 of 2000 and 1/4 is 25% so you could multiply the amount she needed by 4 to get your answer
