Those equations would be Neither

It is not a parallel line because for it to be a parallel line, your slope must be the same. Since the slopes are 5/3 and 5/4, they are not the same.

It is not a perpendicular line because a perpendicular line needs to intersect at a 90 degree angle when they intersect from each other (looks like a X). Usually a perpendicular line have a positive and negative equations. Since the slope are both positive, there is no way they would intersect at a 90 degree angle

So your answer would be Neither.

The equation of the sinusoidal function is y = -2sin(x + 1.5) - 3

<h3>The sinusoidal function</h3>

The minimum and the maximum of the function are

Minimum = -1
Maximum = -5

The amplitude (A) is calculated as:

A = 0.5 * (Maximum - Minimum)

So, we have:

A = 0.5 * (-5 + 1)

A = -2

The vertical shift (d) is calculated as:

d = 0.5 * (Maximum + Minimum)

So, we have:

d = 0.5 * (-5 - 1)

d = -3

The period (P) is calculated as:

P = 2π/B

From the graph,

B = 1

So, we have:

P = 2π/1

P = 2π

So, the amplitude is -2 and the period is 2π.

<h3>The equation of the sine function</h3>

In (a), we have:

A = -2

B = 1

d = -3

A sine function is represented as:

y = A sin(Bx + C) + D

So, we have:

y = -2sin(x + C) - 3

The graph passes through the point (0, -5)

So, we have

-5 = -2sin(0 + C) - 3

Solve for C, we have

C = 1.5

So, we have:

y = -2sin(x + 1.5) - 3

Hence, the equation of the sinusoidal function is y = -2sin(x + 1.5) - 3

Selected value of each decimel number when it is rounded to the nearest whole number

PtichkaEL [24]

Answer:

Remember the decimal <em>hundredths</em> rounding ruleset.

If a decimal is below .50, round down.
If a decimal is .50, round up.
If a decimal is above .50, round up.

View this array below to get a better image.

$\left[\begin{array}{ccc}0.49(down)&0.50(up)&0.51(up)\end{array}\right]$

So, for example, if you had 6.51, you would round that up to 7, and if you had 8.47, you would round that to 8

What is the ratio of red sections to total sections, in lowest terms?

Tanzania [10]

Hello there! Your answer would be 1/4.

So to start, count up the total number of sections, and the number of red sections. There are 16 sections total, and 4 of them are red.

This can give us the ratio 4/16.

But next we need to simplify. What is the biggest number that can be divided by both 4 and 16? 4. So, divide both 4 and 16 by 4 to get your simplified answer.

4÷4/16÷4

1/4

So, the ratio of red sections to total sections, in lowest terms is 1/4.
