Fran deposited 4869 into a savings account that pays simple annual interest rate of 3.25% how much interest will she earn after

Whitepunk [10]

Answer:

$395.61

Step-by-step explanation:

The formula for simple interest is:

$i=Prt$

Where

i is the interest amount

P is the principal amount

r is the rate of interest per time period

t is the time period

Here,

P = 4869

we want to find after 30 months, that converted to years is:

30/12 = 2.5 years

t = 2.5

The annual rate is 3.25% = 0.0325

Now, substituting, we find our answer:

$i=Prt\\i=(4869)(0.0325)(2.5)\\i=395.61$

The interest earned is <u>$395.61</u>

Which expression is the completely factored form of x6−64y3 ?

ss7ja [257]

We are given this

$x^6 -64y^3$

write it as the difference of cubes

$(x^2)^3 -(4y)^3$

use the formula for the difference of cubes

$(x^2-4y) ((x^2)^2+x^2*4y+(4y)^2)$

Now use the formula for the difference of squares as $4y = (2\sqrt{y} )^2$

$(x-2\sqrt{y}) (x+2\sqrt{y}) (x^4+4x^2y+16y^2)$

Step-by-step explanation:

always write what you know

circumference

U = 2 x pi x r

r = d/2

U = 39.25

rearrange and solve for r

U / (2 x pi) = r

solve for diameter

2r = d
