(x^2-6) (x+6) + 25
plz someone answer correctly

Answers

Answer:

x^3+6x^2-6x-11

Step-by-step explanation:

PLEASE GIVE BRAINLIEST

(x² - 6) (x + 6) + 25

x²(x + 6) + -6(x + 6) + 25

x³ + 6x² - 6x - 36 + 25

x³ + 6x² - 6x - 11

Find a solution to the following initial-value problem: dy dx = y(y − 2)e x , y (0) = 1.

Answers

This equation is separable, as

(\mathrm dy)/(\mathrm dx)=y(y-2)e^x\implies(\mathrm dy)/(y(y-2))=e^x\,\mathrm dx

Integrate both sides; on the left, expand the fraction as

\frac1{y(y-2)}=\frac12\left(\frac1{y-2}-\frac1y\right)

Then

\displaystyle\int(\mathrm dy)/(y(y-2))=\int e^x\,\mathrm dx\implies\frac12(\ln|y-2|-\ln|y|)=e^x+C

\implies\frac12\ln\left|\frac{y-2}y\right|=e^x+C

Since y(0)=1, we get

\frac12\ln\left|\frac{1-2}1\right|=e^0+C\implies C=-1

so that the particular solution is

\frac12\ln\left|\frac{y-2}y\right|=e^x-1\implies\boxed{y=\frac2{1-e^(2e^x-2)}}

purchased a toyota 4Runner for $25,635. promised your daughter the suv will be hers when the car is worth $10,000. according to the car dealer the suv will depreciate approximately $3,000 per year,if your daughter is currently 15 years old, how old will she be when the 4Runner will be hers.

Answers

Answer:

  about 20

Step-by-step explanation:

The vehicle must decline in value by $25,635 -10,000 = $15,635. At the rate of $3000 per year, it will take ...

  15,635/3,000 ≈ 5.21167

In 5.2 years, she will be about 20 years old.

PLEASEEE HELP FAST! One solution each is given on four quadratic equations. Assuming that each quadratic equation has two solutions, what is the second solution for each equation?

Answers

Answer:

Step-by-step explanation:

If one solution of a quadratic equation is a complex number (a + bi),

Other solution of the equation will be the conjugate of the first solution.

So the other solution will be in the form of (a - bi)

If one solution is, x = -4 - 5i

Other solution will be, x = -4 + 5i

If one solution is, x = 4 + 5i

Other solution will be, x = 4 - 5i

If one solution is, x = 5 - 4i

Other solution will be, x = 5 - 4i
