Let f(x) = x^2 - 11x - 60.<br> Solve for f(x) using factoring.

Alona [7]

F(x) = X^2 - 11x - 60
Two terms that multiply to -60 and add to -11 so...
F(x) = (X - 15) (x + 4)
Your x-intercepts would be 15 and -4.

Find the distance using the modulus of the difference between z1 = -8 + 3i and z2 = 7 - 4i. Show all work for full credit.

3241004551 [841]

Answer:

$\sqrt{274}$

Step-by-step explanation:

Given $z_1=-8+3i,\ z_2=7-4i.$

1. Find the difference $z_1-z_2:$

$z=z_1-z_2=-8+3i-(7-4i)=-8+3i-7+4i=(-8-7)+(3i+4i)=-15+7i.$

This complex number has real part $Rez=-15$ and imaginary part $Imz=7.$

2. The modulus of complex number z is

$|z|=\sqrt{Re^2z+Im^2z}=\sqrt{(-15)^2+7^2}=\sqrt{225+49}=\sqrt{274}.$

If a polygon has 1127 diagonals, how many sides does the polygon have? (what’s the equation to solve or & answer)

Vlada [557]

We are given : Number of diagonals of a polygon = 1127 diagonals.

We know relation between number of diagonals and number of sides of the polygon.

<h3> $\frac{n(n-3)}{2}=d$ , Where n is the number of sides of the polygon and d is number of diagonals.</h3>

Plugging d=1127 in above formula, we get

$\frac{n(n-3)}{2}=1127$

Multiplying both sides by 2, we get

$n(n-3)=2254$

$n^2-3n=2254$

$n^2-3n-2254=0$

Solving quadratic equation by factoring, we get factors

$\left(n-49\right)\left(n+46\right)=0$

Solving for n, we get

n-49=0

n=49.

n+46=0.

n=-46.

We can't take number of sides by a negative number.

Therefore, number of sides does the polygon have 49 side.
