Answer:

5 < x < 23

Step-by-step explanation:

let the third side be x , then

difference of 2 sides < x < sum of 2 sides

14 - 9 < x < 9 + 14 , that is

5 < x < 23

Answer:

(-2, -9)

explanation:

original coordinates of B: (7, 9)

use the formula: (x, y) ---> (x, -y)

if reflects over x-axis new coordinates: (7, -9)

If horizontally shifted there will be change in x axis,

new coordinates (7-9,-9) → (-2, -9)

Is square root 1 minus sine squared theta = cos Θ true? If so, in which quadrants does angle Θ terminate?

Cloud [144]

Answer:

True; quadrants I & IV

Step-by-step explanation:

We know the relation between sine and cosine function which is given by

$\sin^2 \theta +\cos^2 \theta = 1$

Let us solve this equation for cosine function.

$\cos^2 \theta = 1-\sin^2 \theta$

Take square root both sides. When ever we take square root we need to write the solution in plus minus form

$\sqrt{\cos^2 \theta}=\pm\sqrt{1-\sin^2 \theta}$

$\cos \theta=\pm\sqrt{1-\sin^2 \theta}$

$\cos \theta=-\sqrt{1-\sin^2 \theta}, \sqrt{1-\sin^2 \theta}$

If Θ is in quadrants I and IV then the value will be positive and if Θ is in II and III quadrant then the value is negative.

Hence, if Θ is in quadrants I & IV, then we have

$\cos \theta=\sqrt{1-\sin^2 \theta}$

Thus, the correct option is: True; quadrants I & IV

What is the value of x^3\cdot y^1x 3 ⋅y 1 x, start superscript, 3, end superscript, dot, y, start superscript, 1, end su

satela [25.4K]

The expression $x^3y$ means that you have to cube the value of $x$ and multiply it by the value of $y$ .

So, the value of $x$ is 5, which becomes 125 when cubed. When we multiply it by the value of $y$ , which is 10, the result is 1250:

$x^3y = 5^3\cdot 10 = 125\cdot 10 = 1250$
