Divide using synthetic division, and write a summary statement in fraction form. 2x^4-x^3-15x^2+3x/x+3
aev [14]
So... first off, we sort the dividend, the numerator, in descending order... so, looking at the exponents in this one, is already sorted in descending order, from 4 down to 1, so that's done.

then the divisor, we have x+3, that means x + 3 = 0, x = -3,
so, we'll be using -3 for the synthetic division then.

\bf \cfrac{2x^4-x^3-15x^2+3x}{x+3}\\\\
-------------------------------\\\\

\begin{array}{r|rrrrrrrrrl}
-3&&2&-1&-15&3\\
&&&-6&21&-18\\
--&&-&--&--&--\\
&&2&-7&6&\boxed{-15}&\leftarrow remainder
\end{array}

and now, we'll use those coefficients, dropping the exponents of the polynomial by one, and the remainder, remains as a fraction with the divisior of x+3.

\bf 2x^3-7x^2+6x-\frac{15}{x+3}

Lucy have $6400 if she invests<br> $1200 at 15% interest<br> compounded quarterly?
svet-max [94.6K]

Answer:

  11.4 years

Step-by-step explanation:

We assume you want to know the time it takes for Lucy's investment of $1200 to have a value of $6400. The compound interest formula is good for finding that.

  FV = P(1 +r/n)^(nt)

for principal P invested at rate r per year for t years, compounded n times per year. We want to find t such that ...

  6400 = 1200(1 +0.15/4)^(4t)

  16/3 = 1.0375^(4t) . . . . divide by 1200

  log(16/3) = 4t·log(1.0375) . . . . take logarithms

  t = log(16/3)/(4·log(1.0375)) ≈ 11.4

It will take about 11.4 years for Lucy's investment value to be $6400.

If the Ramirez family deposits $5000 in a savings account at 7.5% interest compounded continuously, how much will be in the acco
GenaCL600 [577]

Answer: The amount is $14794.39 and the interest is $9794.39

Step-by-step explanation: If you deposit <em><u>$5000</u></em><u> </u>into an account paying <em><u>7.5%</u></em> annual interest compounded yearly , how much money will be in the account after <em><u>15 years</u></em>?

To find amount we use formula:

A-P(1+r/n) n*t

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

P=$5000, r=7.5, n=1 and, t=15 years

After plugging the given information we have

A= $5000 (1+0.075/1)^1.15

A= 5000 *1.075^15

A=14794.39

To find interest we use formula  A=P+I'

since A= 14794.39  and P=5000

we have: A=P+I 14794.39=5000+I

I= 14794.39 -5000

I=9794.39
