When the sum of 1.9 and 2.2 is subtracted from the product of 1.9 and 2.2, what is the difference?Please Help!!! :)

Answers

OK the question is asking what happens when you subtract (1.9+2.2) from 1.9x2.2 or more clearly 1.9x2.2-(1.9+2.2) which equals 4.18-4.1 or .08

Which expression could be used to determine the cost of a $50 video game after a 20 percent discount?

Answers

The price of a video game is now 50 dollars after the 20% discount.The question is what is the expression to be able to solve that amount before the 20% discount.=> 100% - 20% = 80%=> 50 is the 80% => 80% = .80Expression = .80 = 50, where x is the unknown number that we need to know.
=> .80 = 50 => .80x / .80 = 50 / .80=> x = 62.5 dollars is the original price of the said video game on sale.

50x.2 is the correct expression.

If a cylinder has a height of 7in and a volume of 2,908.33in^3, find its diameter

Answers

The diameter of the cylinder is approximately 22.94 inches.

To find the diameter of the cylinder, we can use the formula for the volume of a cylinder:

Volume $= \pi * r^2 * h,$

where π is a mathematical constant (approximately 3.14159), r is the radius of the cylinder, and h is the height of the cylinder.

Given that the height of the cylinder is 7 inches and the volume is 2,908.33 cubic inches, we can rearrange the formula to solve for the radius:

Volume $= \pi * r^2 * h$

$2,908.33 = \pi * r^2 * 7$

Dividing both sides of the equation by 7π, we have:

$r^2$ = 2,908.33 / (7π)

$r^2$ ≈ 131.50

Taking the square root of both sides, we get:

r ≈ √131.50

r ≈ 11.47.

The radius of the cylinder is approximately 11.47 inches.

To find the diameter, we multiply the radius by 2:

d = 2 $*$ r

d ≈ 2 $*$ 11.47

d ≈ 22.94

What is solution of a quadratic function?

Solving quadratic function means finding a value (or) values of variable which satisfy the equation. The value(s) that satisfy the quadratic function is known as its roots/ zeroes and x - intercept.

Example-

$x^(2) -3x +2 = 0\n\nx^(2) -2x - x + 2 = 0\n\nx(x - 2) - 1(x - 2) = 0\n\n(x - 1)(x - 2) = 0\n\nx = 1 \, or \, 2$

Here, 1 and 2 are zeroes/ roots/ intercept of the quadratic function $x^(2) -3x +2 = 0$ .
