Find a cubic function that has the roots 5 and 3-2i

Zolol [24]

Answer:

$P(x)=x^3-11x^2+43x-65$

Step-by-step explanation:

If the complex number $3-2i$ is a root of a cubic function, then the complex number $3+2i$ is a root too. Thus, the cubic function has three known roots $5,\ 3-2i,\ 3+2i$ and can be written as

$P(x)=(x-5)(x-(3-2i))(x-(3+2i)),\\ \\P(x)=(x-5)(x^2-x(3-2i+3+2i)+(3-2i)(3+2i)),\\ \\P(x)=(x-5)(x^2-6x+9-4i^2),\\ \\P(x)=(x-5)(x^2-6x+9+4),\\ \\P(x)=(x-5)(x^2-6x+13),\\ \\P(x)=x^3-11x^2+43x-65.$

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

harina [27]

The equation of line is:

$y=-\frac{1}{2}x+6$

Further explanation:

Given

y = 2x + 2

Comparing it with standard form:

y=mx+b

Let m1 be the slope of given line

$m_1=2$

We know that product of slopes of two perpendicular lines is -1

Let m2 be the slope of second line

$m_1.m_2=-1\\2*m_2= -1\\m_2 = -\frac{1}{2}$

Putting the value of m2 in standard form

$y=-\frac{1}{2}x+b$

To find the value of b, putting (6,3) in equation

$3=-\frac{1}{2}(6)+b\\3=-3+b\\3+3=b\\b=6$

Putting the values of b and m, we get

$y=-\frac{1}{2}x+6$

The equation of line is:

$y=-\frac{1}{2}x+6$

A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter ma

Solnce55 [7]

Answer:

Step-by-step explanation:

P=2K

50K+75P=1200, using P from above makes this equation become

50K+75(2K)=1200

50K+150K=1200

200K=1200

K=6, since P=2K

P=2(6)=12

So 12 puppies and 6 kittens were adopted.
