Answer:

The initial amount

Step-by-step explanation:

Let's find equation of line

(0,40)
(4,60)

Slope

$\\ \tt\hookrightarrow m=60-40/4=5$

Equation in point slope form

$\\ \tt\hookrightarrow y-40=5(x)$

$\\ \tt\hookrightarrow y=5x+40$

True [87]

Answer:

x = (74-28)/2

Step-by-step explanation:

We find the perimeter of a triangle by adding the sides together

s1 +s2+s3 = P

The perimeter is 74

s1 +s2+s3 = 74

We know one of the sides is 28

28 +s2+s3 = 74

The other two sides are equal in length, call them x

28 +x+x = 74

Combine like terms

28+2x = 74

We want to solve for x

Subtract 28 from each side

28-28+2x = 74-28

2x = 74-28

Divide each side by 2

2x/2 = (74-28)/2

x = (74-28)/2

Suppose $p(x)$ is a monic cubic polynomial with real coefficients such that $p(3-2i)=0$ and $p(0)=-52$. determine $p(x)$ (in exp

Maslowich

If $p(3-2i)=0,$ then complex number $3-2i$ is a root of cubic polynomial.

If polynomial has real coefficients, then conjugated $3+2i$ is also a root of polynomial.

Then the polynomial will be of a form

$p(x)=(x-(3-2i))(x-(3+2i))(x-a).$

Since $p(0)=-52,$ then

$-52=(0-(3-2i))(0-(3+2i))(0-a),\\ \\-52=(2i-3)(3+2i)a,\\ \\-52=(4i^2-9)a,\\ \\-52=(-4-9)a,\\ \\-13a=-52,\\ \\a=4.$

Therefore,

$p(x)=(x-(3-2i))(x-(3+2i))(x-4),\\ \\p(x)=(x^2-6x+13)(x-4),\\ \\p(x)=x^3-10x^2+37x-52.$
