You have $1,900 in savings for retirement. If your investments earn 8% annually, how much will you have in your retirement accou

natima [27]

Answer:

$3,015

Step-by-step explanation:

To determine the amount that you will have in 6 years, you have to use the formula to calculate the future value:

FV=PV*(1+i)^n

FV= future value

PV= present value= $1,900

i= interest rate= 8%

n= number of periods of time= 6 years

FV=1,900*(1+0.08)^6

FV=1,900*(1.08)^6

FV=3,015

According to this, the answer is that in 6 years you will have $3,015 in your retirement account.

Students were asked to write 6x5 + 8x - 3x3 + 7x7 in standard form.

dimulka [17.4K]

Answer:

$7x^{7} + 6x^{5} - 3x^{3} + 8x$

Step-by-step explanation:

Students are asked to write $6x^{5} + 8x - 3x^{3} + 7x^{7}$ in the standard form.

Now, in the standard form of a polynomial the highest power of the variable takes the leftmost position and the lowest power of the variable takes the rightmost position and the power of variable decreases from left to right.

Therefore, the standard form will be $7x^{7} + 6x^{5} - 3x^{3} + 8x$ . (Answer)

Tanya runs a catering business. Based on her records, her weekly profit can be approximated by the function LaTeX: f\left(x\righ

Shtirlitz [24]

The function

$2x^2-44x-150$

is a parabola concave up, whose solutions are

$2x^2-44x-150=0 \iff x^2-22x-75=0$

from here, you can use the quadratic formula

$x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

to find that the solutions of the parabola are $-3,\ 25$

So, the parabola is positive if $x$ (which wouldn't make sense in our case) or $x$

So, if Tanya caters 25 meals she breaks even, and starting with the 26th meal she will begin to profit.

the area of a rectangle is (y^2-8y+15) square inches. which expression represents a possible length? A. (y+5) B. (y-15) C. (y-2)

Pani-rosa [81]

D. (y-3)
I'm assuming that they want you to find the factors of the quadratic expression, which are (y-5)(y-3). (y-5) isn't up there, so (y-3) is the only solution that's really possible.
