Given f(x) = x -2, if the domain is 5, find the range

Answers

Answer:

Domain: all real numbers

Range: all real numbers

Step-by-step explanation:

There is no restriction on the variable x, so the domain is all reals.

Similarly, the range is all reals as the graph of this function is a line that is neither vertical nor horizontal.

Julie counted 25 players on a visiting soccer team. The actual number of players on the visiting soccer team was 27.What is the percent error in Julie’s measurement? If necessary, round to the nearest percent.

Answers

Percent error is:
(What you got - what you should have got) * 100 / what you should have got

So in this case:
(25-27) * 100 / 27 = 7.407 with the (.407) repeating

The shorter leg of a right triangle is 6 feet shorter than the longer leg. The hypotenuse is 6 feet longer than the longer leg. Find the side lengths of the triangle.

Answers

The length of longer leg is 24 feet, shorter leg is 18 feet and hypotenuse is 30 feet.

Step-by-step explanation:

Let,

Longer leg = a = x

Shorter leg = b = x - 6

Hypotenuse = c = x + 6

As the triangle is right angles, therefore, using pythagoras theorem;

$a^2+b^2=c^2\n(x)^2+(x-6)^2=(x+6)^2\nx^2+(x^2-12x+36)=x^2+12x+36\nx^2+x^2-12x+36=x^2+12x+36\n 2x^2-12x+36=x^2+12x+36$

Adding (-x² - 12x-36) on both sides

$2x^2-12x+36-x^2-12x-36=x^2+12x+36-x^2-12x-36\nx^2-24x=0$

Taking x common;

$x(x-24)=0\n$

Either,

x=0

or,

x-24 = 0 => x=24

As length cannot be 0 therefore,

Longer leg = x = 24 feet

Shorter leg = x-6 = 24-6 = 18 feet

Hypotenuse = x+6 = 24+6 = 30 feet.

The length of longer leg is 24 feet, shorter leg is 18 feet and hypotenuse is 30 feet.

Solve (x + 1 < 5) ∩ (x - 4 > -3).

Answers

Answer:

(1, 4)

Step-by-step explanation:

(x + 1 < 5) is solved by subtracting 1 from both sides of this inequality:

x < 4.

(x - 4 > -3) is solved by adding 4 to both sides: x > 1.

The solution of (x + 1 < 5) ∩ (x - 4 > -3) is thus (1, 4).
