Answer:

$\sqrt{34}$

Explanation:

sub in the values for x1, x2, y1 and y2

$\sqrt{(-2-3)^2+(2-(-1))^2}$

subtract and evaluate

= $\sqrt{(-5)^2+3^2}$

= $\sqrt{25+9}$

= $\sqrt{34}$

Angle one and two add up to 100, if angle one is 2x and angle two is 3x, what is x?

kifflom [539]

Answer:

$angle \: 1 = 2x \\ angle 2 = 3x \\ sum = 1 00 \\ 2x + 3x = 100 \\ 5x = 100 \\ divide \: both \: side \: by \: 5 \\ \frac{5x}{5} = \frac{100}{5} \\ x = 20$

Right triangle XYZ has right angle Z. If the sin(X)=1213 , what is the cos(X)

AlekseyPX

Given:

Right triangle XYZ has right angle Z.

$\sin(x)=\dfrac{12}{13}$

To find:

The value of $\cos x$ .

Solution:

We know that,

$\sin^2(x)+\cos^2(x)=1$

$\cos^2(x)=1-\sin^2(x)$

$\cos(x)=\pm\sqrt{1-\sin^2x}$

For a triangle, all trigonometric ratios are positive. So,

$\cos(x)=\sqrt{1-\sin^2x}$

It is given that $\sin(x)=\dfrac{12}{13}$ . After substituting this value in the above equation, we get

$\cos(x)=\sqrt{1-(\dfrac{12}{13})^2}$

$\cos(x)=\sqrt{1-\dfrac{144}{169}}$

$\cos(x)=\sqrt{\dfrac{169-144}{169}}$

$\cos(x)=\sqrt{\dfrac{25}{169}}$

On further simplification, we get

$\cos(x)=\dfrac{\sqrt{25}}{\sqrt{169}}$

$\cos(x)=\dfrac{5}{13}$

Therefore, the required value is $\cos(x)=\dfrac{5}{13}$ .

David measures how many inches his tomato plant grows every week. What is the independent variable?

Norma-Jean [14]

Answer:

It is tomato plant

Step-by-step explanation:

- The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. - - - The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.

Write the equation of the line that is parallel to

Kruka [31]

Answer:

y = -x + 2

Step-by-step explanation:

Lines that are parallel have the same slope but different

y-intercepts.

So the slope of the parallel line is -x

We can input the x and y points given to solve for the new y-intercept

y = -x + b
8 = -(-6) + b
8 = 6 + b
b = 2

The new line is y = -x + 2. Since these two lines are the same, they are coinciding lines.
