If a = - i and b = 3 , then find the value of the a ^ 2 * b in fully simplified form .

Answers

Answer 1

Answer:

[tex]a^2 * b = 3i^2[/tex]

Step-by-step explanation:

Given

[tex]a = -i[/tex]

[tex]b = 3[/tex]

Required

Determine [tex]a^2 * b[/tex]

To do this, we simply substitute -i for a and 3 for b in [tex]a^2 * b[/tex]

This gives:

[tex]a^2 * b = (-i)^2 * 3[/tex]

Evaluate the expression in bracket

[tex]a^2 * b = i^2 * 3[/tex]

This gives:

[tex]a^2 * b = 3i^2[/tex]

find the average rate of change for the given function from x=0 to x=2​

Answers

Answer:

-4

Step-by-step explanation:

Average rate of change from x = 0 to x = 2:

Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

[tex] a = 0, f(a) = 2 [/tex]

[tex] b = 2, f(b) = -6 [/tex]

Plug in the values into the formula for average rate of change.

[tex] = \frac{-6 - 2}{2 - 0} [/tex]

[tex] = \frac{-8}{2} [/tex]

[tex] = -4 [/tex]

Average rate of change from x = 0 to x = 2 is -4

10. 0.99 11. -60 12. 5.5

Step-by-step explanation:

Use the slope formula:

m = (y2 - y1)/(x2 - x1)

10.

m = (6.24 - 3.27)/(5 - 2) = 2.97/3 = 0.99

11.

m = (240 - 360)/(3 - 1) = -120/2 = -60

m = (8.84 - 6.09)/(7 - 2) = 2.75/5 = 5.5

Answer:

x=1

Step-by-step explanation:

Step 1:Simplify both sides of the equation

4(x-5)+2x=-14

(4)(x)+(4)(-5)+2x=-14

4x+-120+2x=-14

4x+2x+-20-14

6x+-20=-14

6x-20=-14

Step 2: Add 20 to both sides

6x-20+20=-14+20

6x=6

Step 3: Divide both sides by 6
