Answer:

Step-by-step explanation:

The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

Answer:

See below

Step-by-step explanation:

The absolute value of a number is its POSITIVE distance from 0. We notate absolute value as |x|.

For example, if you wanted to determine the absolute value of -5, you would write it as |-5| which is 5.

-5 is 5 away from 0, so this confirms the answer is right.

A town’s population went from 35,000 to 42,000 in 3 years. What was the percent of change?
dolphi86 [110]

Answer:

The population changed by 20% in 3 years

Step-by-step explanation:

The percentage change, is given by the following equation;

Percentage \ change = \dfrac{Final \ value - Initial \value }{Initial \ value} \times 100

The given parameters are;

The initial population of the town = 35,000

The final population of the town = 42,000

The percentage change in the population is therefore;

Percentage \ change \ in \ population= \dfrac{42,000 - 35,000 }{35,000} \times 100 = 20 \%

The population changed (increase) by 20% in 3 years.

A roofer props a ladder against a wall so that the top of the ladder reaches a 30-foot roof that needs repair. If the angle of e
gizmo_the_mogwai [7]
Set this up like a right triangle with the height of the triangle as 30, the angle across from that side, the reference angle, as 55, and the base is your unknown, x.  This means that we have the angle, the side across from it, and the side adjacent to it.  That sounds like the tangent ratio to me!  Tangent of the angle is the side opposite over the side adjacent: tan(55)= \frac{30}{x}.  Solving for x: x= \frac{30}{tan(55)}.  Do that on your calculator in degree mode to get that the distance between the base of the ladder and the wall is 21 feet
