Answer:

1. The right triangles pass the AA similarity congruence theorem.

2. s/q

Step-by-step explanation:

They are similar since they pass the AA( Angle-Angle) similarity theorem.

Similar triangles have corresponding proportional sides so side z corresponds with side s and side x corresponds with q so we would represent that as

s/q

5x+21+178/(x-7)<br> How do I solve for domain and range on this equation?

Luda [366]

The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.

For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.

{-210, -156, -366,-471, -108,-627, -579}

Andru [333]

Option D I and IV only is correct option

Step-by-step explanation:

We need to identify that the numbers {-210, -156, -366,-471, -108,-627, -579} belong to which of the following set of numbers.

I. Rational Numbers

II. Natural Numbers

III. Whole Numbers

IV. Integers

We will consider each option

Rational numbers: numbers that can be written by dividing two integers. They can be positive or negative.

all the numbers given can be divided by 1 to make them fractions. So all numbers are rational numbers.

Natural numbers: numbers that are positive integers excluding 0 i.e 1,2,3...

So, the given numbers are not natural numbers

Whole numbers: all natural numbers including 0. These are positive numbers. So, the given numbers are not whole numbers

Integers: it is a whole number (not fraction) that can be positive,negative or zero. So, the numbers given are integers.

So, Option D I and IV only is correct option

Please help me with this question

Answer:

Step-by-step explanation:

Look at the picture.

$sine=\dfrac{opposite}{hypotenuse}$

We need a hypotenuse length.

Use Pythagorean theorem:

$hypotenuse^2=leg^2+leg^2$

We have

$leg=9,\ leg=12,\ hypotenuse=x$

Substitute:

$x^2=9^2+12^2\\\\x^2=81+144\\\\x^2=225\to x=\sqrt{225}\\\\x=15$

For the sine we have:

$opposite=12, hypotenuse=15$

Substitute:

$\sin\alpha=\dfrac{12}{15}=\dfrac{12:3}{15:3}=\dfrac{4}{5}$

What is an equation of thebline that is parallel to y=4x-1 and that passes through point (-3,5)

Hunter-Best [27]

Answer:

The equation would be y = 4x + 17

Step-by-step explanation:

To find this line, start with the slope. Since it is parallel to the first line and parallel lines have the same slope, we know the slope to be 4. Given this we can use point-slope form and solve for y to get the equation.

y - y1 = m(x - x1)

y - 5 = 4(x + 3)

y - 5 = 4x + 12

y = 4x + 17
