0.95× 10to the power of 8 is not in scientific notation. Scientific notation is when the all but the first number is be hundredths a decimal. So for it to be in scientific notation it would look like this : 9.5×10to the power of 8.

Solve 5x + 3x - 6 = 42​
xxMikexx [17]

Answer:

The answer to your question is x = 6

Step-by-step explanation:

Equation                   5x + 3x - 6 = 42

Process

Step 1. Add 6 units in both sides

                                 5x + 3x - 6 + 6 = 42 + 6

Step 2. Simplify

                                  5x + 3x = 48

Step 3. Simplify like terms

                                         8x = 48

Step 4. Divide by 8 both sides

                                        8x/8 = 48/8

Step 5. Simplify

                                          x = 6

What is the equation of the circle with center (16, - 12) and a radius of 5
eimsori [14]

Answer:

x^2+y^2-32x+24y+375=0

Step-by-step explanation:

Equation of circle with given centre (h,k) and radius=r is

(x-h)^2+(y-k)^2=r^2

Given centre are=(16, - 12) and radius= 5

So equation of circle=

(x-16)^2+(y- -12)^2=5^2

x^2-32x+256+y^2+24y+144=25

x^2+y^2-32x+24y+375=0

convert the polar representation of this complex number into its rectangular form: z=5(cos pi+i sin pi)
Feliz [49]

Answer:

The complex number z = -5 into its rectangular form

Step-by-step explanation:

* Lets revise the complex numbers

- If z = r(cos Ф ± i sin Ф), where r cos Ф is the real part and i r sin Ф is the

 imaginary part in the polar form

- The value of i = √(-1) ⇒ imaginary number

- Then z = a + bi , where a is the real part and bi is the imaginary part

  in the rectangular form

∴ a = r cos Ф and b = r sin Ф

* Lets solve the problem

∵ z = r (cos Ф ± i sin Ф)

∵ z = 5 (cos π + i sin π)

∴ The real part is 5 cos π

∴ The imaginary part is 5 sin π

- Lets find the values of cos π and sin π

∵ The angle of measure π is on the negative part of x axis at the

  point (-1 , 0)

∵ x = cos π and y = sin π

∴ cos π = -1  

∴ sin π = 0

∴ a = 5(-1) = -5

∴ b = 5(0) = 0

∴ z = -5 + i (0)

* The complex number z = -5 into its rectangular form
