what function models the height of the periscope lens at time t? If the periscope reaches its maximum Heught after ascending for 22 seconds, what is the maximum height in feet? ( 24 inches above the surface and ascends at 6 inches per sec.)​

Answers

Answer:

Step-by-step explanation:

First we are going to find the function which models the height of the

periscope lens at time t.

Let the 2 be height of the periscope.

The height of the periscope at the beginning is 24 inches. It ascends at 6

inches per second. The expression which describes how much it has raised,

at the moment, is 6t.

The function is sum of beginning height and how much it has raised, 2 = 24 + 6t.

To find maximum height of the periscope, we need to evaluate function

for + = 22.

2 = 24 + 6(22)

= 24 + 132

156

Substitute 22 for t.

Multiply.

Maximum height in inches is 156.

We know that 1 foot is 12 inches.

So the function that describes converting feet to inch is y :

= 12x. Where y

represents number of inches and a number of feet.

U = 12.2

156

12x

12

-n=

156

12

2 = 13

Substitute 156 for y.

Divide both sides by 12.

Maximum height in feet is 13.

The height function modeled by the periscope is an illustration of a linear function.

The height function modeled by the periscope is  [tex]\mathbf{h(t) = 24+ 6t}[/tex]The maximum height is 156 inches

The given parameters are:

[tex]\mathbf{Start = 24\ inches}[/tex]

[tex]\mathbf{Rate = 6\ inches/second}[/tex]

The function model of the height is calculated using:

[tex]\mathbf{h(t) = Start + Rate \times t}[/tex]

Where: t represents the time in seconds

So, we have:

[tex]\mathbf{h(t) = 24+ 6\times t}[/tex]

This gives

[tex]\mathbf{h(t) = 24+ 6t}[/tex]

After 22 seconds, the height of the periscope would be

[tex]\mathbf{h(22) = 24+ 6 \times 22}[/tex]

Multiply

[tex]\mathbf{h(22) = 24+ 132}[/tex]

Add

[tex]\mathbf{h(22) = 156}[/tex]

Hence, the maximum height is 156 inches

OPTION 1, 3

Step-by-step explanation:

I don't know how to explain why these are the correct options, except for basing my observations from the given graph.

Option 1: Attah Shipping does deliver a 20-kg package for $60 [as given by coordinates, (20, 60) -- orange line].

Option 3: The 30-kg line is the last, right-most line on the graph. That's the last point where Kwan Shipping's blue line crosses (within the observable region of the graph). If you look carefully, it is the same height as where Attah Shipping's 25-kg mark is. This means that a 30kg package costs $75 for Kwan Shipping, while it costs Attah Shipping $75 to ship a 25kg package. (You could draw a horizontal line across y = 75 to see what I'm talking about).

In problem 9, the mistake is that -40 was subtracted instead of -400.

Here’s Why:

We first see that -6x is subtracted from both sides to cancel the +6x out on the left side and combine it with the other like term on the right side, which is 16x. That step is correct.

The next step, we see that -40 is subtracted from 400. THIS IS THE ERROR. To cancel out the 400, then -400 should be taken from it and not -40! This is because the constant of 400 on the left side must be canceled out by -400 from it to make it 0, so that it can combine like terms with the constant on the left side of 150.

So, the error is that -40 was taken instead of -400.

what is 3x+3=6x-57 i need ur help

Answers

Answer:

x=20

Step-by-step explanation:

Answer:

x=20

Step-by-step explanation: Sorry the explination is long i got it of a website i use for my math tests.

Simplifying

3x + 3 = 6x + -57

Reorder the terms:

3 + 3x = 6x + -57

Reorder the terms:

3 + 3x = -57 + 6x

Solving

3 + 3x = -57 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

3 + 3x + -6x = -57 + 6x + -6x

Combine like terms: 3x + -6x = -3x

3 + -3x = -57 + 6x + -6x

Combine like terms: 6x + -6x = 0

3 + -3x = -57 + 0

3 + -3x = -57

Add '-3' to each side of the equation.

3 + -3 + -3x = -57 + -3

Combine like terms: 3 + -3 = 0

0 + -3x = -57 + -3

-3x = -57 + -3

Combine like terms: -57 + -3 = -60

-3x = -60

Divide each side by '-3'.

x = 20

Simplifying

x = 20
