A function f(x) = x^2 - 4 has a domain as the set of integers

mel-nik [20]

Answer:

8

Step-by-step explanation:

f(x) = (x+2)(x-2)

Substituting x=1 into f(x):

f(1) = 3*-1

= -3

Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.

Hence,

3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8

This can be confirmed with a graph, as attached below.

Variable y varies directly with variable x, and y = 16 when x = 12. Enter the constant of variation in lowest terms. y = x

andrew11 [14]

k = 1.33 or 1 1/3

Formula of Direct variation. Where y is equal to the product of the constant of variation times x.

y = kx
16 = k * 12
k = 16/12
k = 1 4/12 = 1 1/3

Constant of variation is 1 1/3 or 1.33.

You worked from 8:30am - 2:15pm with a 12 hour lunch break. How long did you work?

alexandr402 [8]

5.75 if you don’t count the lunch break because I don’t think a lunch break can be twelve hours because it would’nt even be a shift

Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.

Mazyrski [523]

Complete Question:

Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.

Write an equation using the Pythagorean Theorem to find the value of x.

How far are Ava's feet from the balloon?

Answer:

Ava's feet is 17ft away from the balloon

Step-by-step explanation:

Given

$height = 8ft$

$distance = 15ft$

The attached image represents the scenario

Using Pythagoras theorem (from the attachment), we have:

$x^2 = 8^2 + 15^2$

$x^2 = 64 + 225$

$x^2 =289$

Take square roots of both sides

$x = \sqrt{289$

$x = 17$
