MATCH THE number WITH ITS OPPOSITE

ycow [4]

To match the number with the opposite, we are flipping the sign. If the sign is originally a negative, it would become a positive, and vice versa.

Term: 3.2 Match (Opposite): B) - 3.2

Term: -2.3 Match (Opposite): D) 2.3

Term: -1.5 Match (Opposite): C) 1.5

Term: 5.1 Match (Opposite): A) -5.1

Which of the following illustrates a phase shift?

Natasha_Volkova [10]

Answer:

A. y = -2 - cos(x-π)

Explanation:

The general form of the trig equation is:

y = A sin (Bx + C) + D

where:

A is the amplitude

$\frac{2\pi}{B}$ is the period

$\frac{-C}{B}$ is the phase shift

D is the vertical shift

Now, let's check the choices:

A. y = -2 - cos(x-π)

$\frac{-C}{B} = \frac{\pi}{1} = \pi$

Therefore, the function has a phase shift of π

B. y = 3 cos(4x)

$\frac{-C}{B} = \frac{0}{4} = 0$

Therefore, the function has no phase shift

C. y = tan(2x)

$\frac{-C}{B} = \frac{0}{2} = 0$

Therefore, the function has no phase shift

D. y = 1 + sin(x)

$\frac{-C}{B} = \frac{0}{1} = 0$

Therefore, the function has no phase shift

Based on the above, the correct answer is A

Hope this helps :)

Robert has a container in the shape of a cube with an edge length of 6.1 cm. What is the volume of the container?

Setler79 [48]

Since it's a cube all the side lengths are the same. So the calculation would be 6.1x6.1x6.1 or 6.1^3
V=226.981cm^3
V=Length x width x height
