Which function is even? check all that applya. y = csc x
b. y = sin x
c. y = sec x
d. y = cos x

Answers

Answer 1

Answer:

The function is even will be y = sec x and y = cos x. Then the correct options are C and D.

What is an even function?

Even Function - A true function f(x) is said to be an even function if the output value of f(-x) is the same as the f(x) for all values of x in the domain of f.

The equation should be stored in an even function:

f(-x) = f(x)

Check all that apply.

a. y = csc x, then replace x with -x. Then we have

y = csc -x

y = 1/sin -x

y = - 1/ sin x

y = -csc x

b. y = sin x, then replace x with -x. Then we have

y = sin -x

y = - sin x

c. y = sec x, then replace x with -x. Then we have

y = sec-x

y = 1/cos -x

y = 1/ cos x

y = sec x

d. y = cos x, then replace x with -x. Then we have

y = cos -x

y = cos x

Thus, the function is even will be y = sec x and y = cos x.

Then the correct options are C and D.

The center of mass is defined as a point on the straight line between two objects with masses m1 and m2such that L1/L2= m1/m2
What are the coordinates of the center of mass?

Answers

Answer:

Step-by-step explanation:

given n particles of masses m1, m2, .... mn located at points (x1, y1), ... (xn,yn) the coordinates of the center of mass are given by

$x_c = (\sum_(i=1)^(n)m_ix_i)/(\sum_(i=1)^(n)m_i)$

$y_c = (\sum_(i=1)^(n)m_iy_i)/(\sum_(i=1)^(n)m_i)$

So, using this formulas we get that

$x_c = (m_1x_1+m_2x_2)/(m_1+m_2)$

$y_c = (m_1y_1+m_2y_2)/(m_1+m_2)$

which corresponds to answer D

Answer:

The correct answer is D.

Which statements are true about triangle XYZ? Select three options.XY measures units.
YZ measures units.
ZX measures units.
XYZ is a right triangle.
XYZ is a scalene triangle.

Answers

First, second and fourth options are true about triangle XYZ.

XY measures $√(26)$ units.

YZ measures $√(52)$ units.

ZX measures $√(26)$ units.

XYZ is a right triangle.

What is right triangle?

A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

Given X (-1, 5), Y (4, 4), Z (-2, 0)

Distance between two points D = $\sqrt{(x_(2)-x_(1)) ^(2) +(y_(2)-y_(1)) ^(2)}$

|XY| = $\sqrt{(4-5)^(2) +(4+1)^(2) } =\sqrt{1^(2)+5^(2) } =√(26)$

|YZ| = $\sqrt{(0-4)^(2) +(-2-4)^(2) } =\sqrt{4^(2)+6^(2) } =√(52)$

|XZ| = $\sqrt{(0-5)^(2) +(-2+1)^(2) } =\sqrt{5^(2)+1^(2) } =√(26)$

$|XY|^(2) +|XZ|^(2) =|YZ|^(2)$

So, XYZ is a right triangle.

So, the first, second and fourth options are correct.
