E graph shows the altitude of a helicopter over time.

Mathematics
1 answer:
DaniilM [7]4 years ago
4 0

Let

x-------> the time

y-------> the altitude of a helicopter

Step 1

<u>Find the slope of the line</u>

we know that

the slope m of the line between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

we have

(x1,y1)=(0,10,000)\\(x2,y2)=(15,4,000)

substitute in the formula

m=\frac{(4,000-10,000)}{(15-0)}

m=\frac{(-6,000)}{(15)}

m=-400\frac{feet}{minute}

therefore

<u>the answer is the option </u>

The slope is -400 . This means that the helicopter descends 400 ft each minute.

Met paid $9 for 2 tuna sandwhiches at the same rate, how much does meg pay for 8 tuna sandwiches
enyata [817]
Hey there!


To solve this, first divide the numbers 9 and 2 . . .

9 divided by 2 = 4.50

This means that it costs $4.50 for 1 sandwich.

Next, multiply 4.50 and 8 . . .

4.50 x 8 = 36 <-----

Meg paid $36 for 8 tuna sandwiches.

Hope this helps you.
Have a great day!

What is the amplitude of sin ?
sp2606 [1]

You haven't provided a graph or equation so I will tell the simplified meaning of amplitude instead.

Amplitude, is basically a distance from midline/baseline to the maximum or minimum point.

For sine function, can be written as:

\displaystyle \large{ y = A \sin(bx  -  c) + d}

  • A = amplitude
  • b = period = 2π/b
  • c = horizontal shift
  • d = vertical shift

I am not able to provide an attachment for an easy view but I will try my best!

We know that amplitude or A is a distance from baseline/midline to the max-min point.

Let's see the example of equation:

\displaystyle \large{y = 2 \sin x}

Refer to the equation above:

  • Amplitude = 2
  • b = 1 and therefore, period = 2π/1 = 2π
  • c = 0
  • d = 0

Thus, the baseline or midline is y = 0 or x-axis.

You can also plot the graph on desmos, y = 2sinx and you will see that the sine graph has max points at 2 and min points at = -2. They are amplitude.

So to conclude or say this:

If Amplitude = A from y = Asin(x), then the range of function will always be -A ≤ y ≤ A and have max points at A; min points at -A.
