Answer:

B: y=sinx

Step-by-step explanation:

the parent sine function is a repeating function that goes from 0 to 1, with sin(0)=0 sin(pi/2)=1 sin(pi)=0 sin(3pi/2)=-1 and sin(2pi)=0, π≈3.1415926 and we see on this graph that the graph matches at all these major points.

the cosine parent function is essentially the same thing but shifted to the left by π/2. It is essential to familiarize yourself with the unit circle and the key angles and their respective sin and cosine values.

The answer is y = sin x!!

Answer: (2, 5)

Step-by-step explanation:

y = 2x + 1 y = 4x − 3

Eliminate the equal sides of each equation and combine.

2x + 1 = 4x − 3

Solve 2x + 1 = 4x − 3 for x.

Move all terms containing x to the left side of the equation.

Subtract 4x from both sides of the equation.

2x + 1 − 4x = −3

Subtract 4x from 2x.

−2x + 1 = −3

Move all terms not containing x to the right side of the equation.

Subtract 1 from both sides of the equation.

−2x = −3 − 1

Subtract 1 from −3.

−2x = −4

Divide each term by −2 and simplify.

x = 2

Evaluate y when x = 2.

Substitute 2 for x. y = 4 (2) − 3

Simplify 4 (2) − 3.

Multiply 4 by 2.

y = 8 − 3

Subtract 3 from 8.

y = 5

The solution to the system is the complete set of ordered pairs that are valid solutions.

The result can be shown in multiple forms.

Answer:

B)

Step-by-step explanation:

For the function [tex]y=-5x[/tex], all coordinates this line passes through should make this inequality true.

[tex]\begin{case}y=5(-7)=35\\y=-2(-5)=10\\y=2(-5)=-10\end{case}[/tex]

This corresponds with table B.

Answer:

[tex]Black = 4[/tex]

[tex]White = 16[/tex]

Step-by-step explanation:

Given

[tex]Black : White = 1 : 4[/tex]

[tex]Total = 20[/tex]

Required

Determine the number of each type used

Convert each ratio to fraction.

For Black, we have:

[tex]Black = \frac{1}{1 + 4} = \frac{1}{5}[/tex]

For White, we have:

[tex]White = \frac{4}{1 + 4} = \frac{4}{5}[/tex]

The number of tiles for each is then calculated as:

[tex]Black = \frac{1}{5} * Total[/tex]

[tex]Black = \frac{1}{5} * 20[/tex]

[tex]Black = \frac{20}{5}[/tex]

[tex]Black = 4[/tex]

[tex]White = \frac{4}{5} * Total[/tex]

[tex]White = \frac{4}{5} * 20[/tex]

[tex]White = \frac{4 * 20}{5}[/tex]

[tex]White = \frac{80}{5}[/tex]

[tex]White = 16[/tex]

Step-by-step explanation:

The vertical distance between the student and the helicopter is 341.5 feet.

Trigonometric angles are the angles in a right-angled triangle using which different trigonometric functions can be represented. Some standard angles used in trigonometry are 0º, 30º, 45º, 60º, 90º.

Given that, a student is riding a bicycle and sees a traffic light that is 50 feet away.

Here, sinx°= 14/50

sinx°=0.28

x°=16.26°

Now tan16.26°=14/p

0.2916=14/p

p=14/0.2916

p=48

tan82°=v/48

7.1153=v/48

v=7.1153×48

v=341.5 feet

Therefore, the vertical distance between the student and the helicopter is 341.5 feet.

Answer:

2500 pounds

Step-by-step explanation:

There are 2000 pounds in one ton.

Find the weight of the first truck in pounds:

7.5(2000)

= 15000

Find the weight of the second truck in pounds:

8.75(2000)

= 17500

Now, find the difference in the weight:

17500 - 15000

= 2500 pounds

So, the difference in the weight of the trucks in pounds is 2500 pounds

Step-by-step explanation:

The table that shows the relationship between the weights of pints of blueberries is a linear regression function

The table entry is given as:

x 0   1     2     3       4     5

y 0 0.8 1.50 2.20 3.0 3.80

See attachment for the graph

A line that could best approximate the points could go through the origin (0,0) and (5,3.75)

We have the points to be (0,0) and (5,3.75)

Since the line passes through the origin, the equation of the line would be:

[tex]y = \frac{y_2}{x_2}x[/tex]

So, we have:

[tex]y = \frac{3.75}{5}x[/tex]

[tex]y = 0.75x[/tex]

Hence, the equation of the line is y = 0.75x

This means that x = 10.

So, we have:

y = 0.75 * 10

y = 7.5

Hence, ten pints of blueberries weigh about 7.5 pounds.

The unit rate is $2.25 per pound

Ten pints of blueberries weigh about 7.5 pounds.

So, the cost of 10 pints is:

Cost = 7.5 * 2.25

Cost = 16.875

Ten pints of blueberries will cost about $16.875

I'm not sure if it's correct...........

Answer:

We conclude that:

f(g(-2)) = -3

Step-by-step explanation:

Given

To determine

In order to determine f(g(-2)), first we need to determine g(-2)

so substituting x = -2 in g(x) = x-3

g(-2) = -2 - 3

        = -5

Thus,

f(g(-2)) = f(-5)

now substitute x = -5 in the function f(x) = 2x+7

f(x) = 2x+7

f(-5) = 2(-5) + 7

f(-5) = -10 + 7

f(-5) = -3

so

f(g(-2)) = f(-5) = -3

Therefore, we conclude that:

f(g(-2)) = -3
