Answer:

no solution

Step-by-step explanation:

Given

- 5 | x + 1 | = 10 ( divide both sides by - 5 )

| x + 1 | = - 2

To have a solution the right side of the equation must be positive or zero

No absolute value can have a negative solution

Thus the equation has no solution

Find the first three iterates of the function f(z) = z2 + c with a value of c = 2 - 3i and an initial value of z0 = 1 + 2i.

Artist 52 [7]

Answer:

Step-by-step explanation:

We have: (I rewrote the function)

$f(z_n)={z_{n-1}} ^2+c$

Given that:

$\displaystyle c=2-3i \text{ and } z_0 = 1 + 2 i$

The first iterate will be:

$\displaystyle \begin{aligned} f(z_1)&=(z_0)^2+c \\ &=(1+2i)^2+(2-3i) \\ &= (1+4i+4i^2)+(2-3i) \\ &=1+4i-4+2-3i \\ &=-1+i \end{aligned}$

The second iterate will be:

$\begin{aligned}f(z_2) &=(z_1)^2+c\\ &=(-1+i)^2+(2-3i) \\&= (1-2i+i^2)+(2-3i) \\&=1-2i-1+2-3i \\&=2-5i \end{aligned}$

And the third iterate will be:

$\begin{aligned} f(z_3)&=(z_2)^2+c\\ &=(2-5i)^2+(2-3i) \\ &=(4-20i+25i^2)+(2-3i) \\ &=4-20i-25+2-3i \\ &=-19-23i \end{aligned}$

Hence, our answer is C.

If the radius of a circle is 3 meters, how long is the arc subtended by an angle measuring 30°?

FromTheMoon [43]

Circumference of entire circle = 2 * PI * radius
2 * PI * 3 = 18.85 meters
a 30 degree arc is (30/360) or 1/12 of a circle.
So the arc equals (18.85 meters / 12) or 1.57 meters.

Answer:

-52

Step-by-step explanation:

plug 2 into u(x) which is equal to

2(5) + 1= 5

plug 5 into w(x) which is equal to

-2(5^2) - 2

-2(25) - 2

-50 - 2 = -52
