Ms. Brooks put $1200 in a 3 retirement account that offers 8% interest compounded annually. Ms. Brooks makes no additional depos

Leona [35]

Answer:

$1,408.21.

Step-by-step explanation:

Since it is compounded annually we could use the formula

A=Pe^rt

We know that the initial amount she deposits is $1200, as stated by the problem. That is our P.

e is well, the e in your calculator which is approximately: 2.7182818284590452353602874713527

r is the rate which is 8%, although you must convert this into a decimal, which would be 0.08 as your r.

Lastly, t is the time, so in this case, 2 years.

And then plug in the values.

A=1200(e)^(0.08)(2)

A=1200(e)^(0.16)

A=1200(1.173510870991810235018611086892)

A=1,408.2130451901722820223333042704

Now since it is a money problem we must put it in the correct format.

A=$1,408.21

Your high school freshman class consists of 760 students. In recent years only 4 out 7 students actually graduated in four years

Art [367]

760 total students....4 out of 7 graduated...3 out of 7 didn't

so 4/7(760) = 3040/7 = 434.28 <== so approx. 434 will graduate
and 3/7(760) = 2280/7 = 325.7...and approx. 326 won't graduate

100 points PLEASE ANSWER ASAP thank you so much

Fudgin [204]

Answer:

$\textsf{Apply the Perfect Square Formula}\quad (a + b)^2 = a^2 + 2ab + b^2:$

$\implies (a+bi)^2=a^2+2abi+(bi)^2$

$\textsf{Apply exponent rule} \quad (a\cdot b)^c=a^cb^c:$

$\implies a^2+2abi+b^2i^2$

$i=\sqrt{-1} \implies i^2=-1$

$\textsf{Apply imaginary number rule} \quad i^2=-1:$

$\implies a^2+2abi+b^2(-1)$

$\implies a^2+2abi-b^2$

$\textsf{Collect the real parts:}$

$\implies a^2-b^2+2abi$

$\textsf{Factor the real parts by applying the Difference of Two Squares Formula}\\x^2-y^2=(x+y)(x-y) :$

$\implies (a+b)(a-b)+2abi$

Determine if each function is linear or nonlinear.

Akimi4 [234]

Answer:

Linear: y = x, y = x/2 - 3, 3x + 2 = 12

Nonlinear: y = 6/x - 2, y = 3x^3 + 5

Step-by-step explanation:

Linear functions form straight lines while nonlinear functions do not.
