You plot the points and use the distance formula to find the length of the lines between the points. Distance formula: d=\sqrt{(}x_{2}  -x_{1} )^2 + (}y_{2}  -y_{1} )^2\\

Then use the pythagorean theorem with the sides, (C^2=A^2+B^2, c=longest side) if the equation works then it is a right triangle.

The directions on a sewing pattern say to buy an extra 12.5% of fabric to account for error. Sam needs 2.75 yards of fabric to m
uranmaximum [27]

Answer:

Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

Step-by-step explanation:

Total fabric needed by Sam = 2.75

According to directions on a sewing pattern they say to buy an extra 12.5%

So, extra fabric would be: 12.5% of 2.75

Solving

12.5\% \ of \ 2.75\\=\frac{12.5}{100}\times 2.75 \\=0.343

Now adding 0.343 into 2.75 to get extra fabric quantity:

2.75+0.343

=3.09

Therefore Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

A person places $686 in an investment account earning an annual rate of 3.8%, compounded continuously. Using the formula V = Pe^
kykrilka [37]

Answer:

V = $1213.03

Step-by-step explanation:

We can determine the amount of money after 15 years with the given formula:

V = Pe^{rt}   (1)

Where:

V: is the value of the account in t years =?

P: is the principal initially invested = $686                

r: is the rate of interest = 3.8% = 3.8/100 = 0.038

t: is the time = 15 years

By substituting the above values into equation (1) we have:

V = Pe^{rt} = 686*e^{(0.038*15)} = 1213.03  

               

Therefore, the amount of money is $1213.03.

I hope it helps you!
