What are the solutions of the quadratic equation? 2 x 2 – 16 x + 32 = 0

Answer: x = 4 twice

Step-by-step explanation:

The given quadratic equation is expressed as

2x^2 - 16x + 32 = 0

Dividing the left hand side and the right hand side of the equation by 2, it becomes

x^2 - 8x + 16 = 0

We would find two numbers such that their sum or difference is -8x and their product is 16x^2. The two numbers are - 4x and - 4x. They,

x^2 - 4x - 4x + 16 = 0

x(x - 4) - 4(x - 4) = 0

x - 4 = 0 or x- 4 = 0

x = 4 twice

Answer:

4 - 16 x + 32 = 0

- 16 x = - 4 - 32

candy wants to have 600 copies of his resume printed. His local print shop charges $22.40 for the first 400 copies and $10 for e
goblinko [34]

Answer:

$44.94

Step-by-step explanation:

400+100+100 = 600

22.40 + 10 +10 = 42.40

(22.40 for the first 400 and 10 for each additional 100)

If tax is 6%, you can multiply the whole thing (42.40) by 1.06 to get the total amount of 44.94.


Why 1.06? If you think about it, tax is 6%. 6% is the same as 0.06. You pay 100% for the products, so with tax, it's the equivalent of 106%, or 1.06.

What is the radius of a sphere with a surface area of 100TCm ?
tensa zangetsu [6.8K]

The radius is 5cm

Step-by-step explanation:

The surface area of a sphere is given by:

SA = 4\pi r^2

Here

Given

SA = 100π cm^2

Putting the values in the formula

100\pi = 4\pi r^2\\r^2 = \frac{100\pi}{4\pi}\\r^2 = 25

Taking square root on both sides

\sqrt{r^2} = \sqrt{25}\\r = 5 cm

The radius is 5cm

Keywords: Surface area, Radius
