Answer:

380d + 530t > 21,000

Step-by-step explanation:

Each DVD costs $380, we can represent that as:

380d

Each TV costs $530, we can represent that as:

530t

We add these together to find the total profit:

380d + 530t

The manager predicts that whatever the total profit is, will be more than $21,000. So, we represent that as this:

380d + 530t > 21,000

And that is the final answer.

I hope this helps!!

Answer:

x ≥ 2

Step-by-step explanation:

1/6(30x+18) ≥ 13

Distribute the left side

5x + 3 ≥ 13

Subtract 3 from both sides

5x ≥ 10

Divide both sides by 5

x ≥ 2

For [tex]\sqrt{25}[/tex] it will be plus or minus [tex]\sqrt{5}[/tex]

For [tex]\sqrt{-25}[/tex] it will be plus or minus [tex]\sqrt{5i}[/tex]

Step-by-step explanation:

Well for [tex]\sqrt{-25}[/tex] it will be 5i

Because i = -1  

At t = 0 the height is not zero because the cannonball is at the end of the barrell of the cannon.

If we define H as the maximum height and T as the time when the cannonball hits the ground, the domain and range are:

domain: [0, T]

range: [0, H]

The height is modeled by the graphed parabola.

The height equal to zero would mean that the cannonball is on the ground. Now, at t = 0 we assume that the cannonball is leaving the barrel of the cannon (which is at some given height above the ground). This is why at t = 0 the height of the cannonball is not equal to 0.

Now we also want to describe the domain and range of the graphed function. The domain is the set of the inputs of the function, we can see that it goes from t = 0, when the cannonball is shooted, to a given time T which is when the cannonball reaches the ground.

For the range (the set of the outputs) we can see that it will go from 0 (the ground) to the maximum value that we can see in the graph, a height H.

So, domain: [0, T]

      range: [0, H]

We need to know about graph of a function to solve this problem. The answer to (A) is f(4)= -3 and (B) for x= f(x)=2 solutions are -5 and -1.

In a graph of a function, the input values are along the x-axis and the output values are along the y-axis. At any point, the x-coordinate gives the value that is entered and the y-coordinate gives the result. For any point lying on the y-axis, x-coordinate is 0 and for any point lying on the x-axis, y-coordinate is 0. In the given graph we need to first find the value of f(4). For this we see at what point on the graph a vertical line from x=4 intersects with the line. The intersection point is (4,-3), so f(4)=-3. For part (B) we need to solve for f(x)=2, we have to draw a horizontal line from y=2 to see where it intersects with the graph, here we find two intersection points (-5,2) and (-1,2) so we have two solutions for f(x)=2, -5 and -1.

Therefore we evaluated f(4) to get -3 and we got two solutions for f(x)=2, -5 and -1.

The cosine function that could model the block's height in inches above the ground at time t seconds is:

h(t) = 9cos(1.67π(x - 2.1)) + 39.

The cosine function is defined as follows:

g(x) = acos(bx+c)+d.

The coefficients have these following roles:

In this problem, we have that the maximum value is of 48 and the minimum value is of 30(difference of 18), hence the amplitude is given as follows:

2a = 18

a = 9.

A standard cosine function with amplitude 9 would vary the between -9 and 9, while this one varies between 30 and 48, hence the vertical shift is of d = 39.

The minimum and maximum values form half the period, hence:

π/B = 2.7 - 2.1

B = π/0.6

B = 1.67π.

The maximum value in the standard function is at x = 0, while at this function is at x = 2.1, hence the phase shift is of 2.1 units to the right, that is, c = -2.1.

Hence the cosine function is:

h(t) = 9cos(1.67π(x - 2.1)) + 39.

This function is graphed at the end of the answer, showing that the minimum and the maximum values are as desired.

The translation of the parent function f (x) = | x | depends upon whether x value has been changed of whether the y value has been changed.

We are given the parent function as:

f (x) = | x |

Now, we need to match the functions with their correct translations.

For the function f (x) = | x | - 4:

This can also be written as:

f (x) + 4 = | x |

So, the translation will be vertical translation up 4 units.

For the function f (x) = | x + 4 | :

The translation for this will be horizontal translation right 4 units as x will increase by 4 units.

For the function f (x) = | x | + 4:

This can also be written as:

f (x) - 4 = | x |

So, the translation will be vertical translation down 4 units.

For the function f (x) = | x - 4 | :

The translation for this will be The translation for this will be horizontal translation right 4 units as x will increase by 4 units as x will decrease by 4 units.

Therefore, we get that, the translation of the parent function depends upon whether x value has been changed of whether the y value has been changed.

Answer:

$39.88

Step-by-step explanation:

She started with $17

spent $0.78 so

17-0.78 = $16.22

then she got $6.76 3.5 times so

6.76*3.5 = 23.66 and that's what her mom gave her

23.66 + 16.22 = 39.88

She now has a total of $39.88

the answer would be: 39.88

because

17-0.78=16.22

and

6.76*3.50=23.66

so

23.66+16.22=39.88
