Measuring the Wind Speed of a HurricaneWhen measuring the wind speed of a hurricane or similar storm, meteorologists don’t want to get hit by flying debris. They use a measure available to them in the comfort of their TV studio. Luckily for the meteorologists, the barometric pressure is linearly related to the wind speed.Suppose scientists compared the wind speeds and barometric pressure readings of two severe storms over the Atlantic Ocean. For one of the storms, the barometric pressure was 1,000 mb (millibars), and the maximum wind speed was 100 kmh (kilometers per hour). The second had a barometric pressure of 960 mb and maximum wind speeds of 180 kmh. (a)Develop a rule that you could use to predict the wind speed given any barometric pressure.(b)Use your rule to predict the wind speed of a hurricane with a barometric pressure of 980 mb. Using what you know about linearity, explain why your prediction is reasonable. (c)Interpret the intercept for wind speed in this context (i.e., as it pertains to the weather).(d)Explain the meaning of slope in this context.

Answers

Answer 1

Answer:

So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.

Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.

Slope= (180-100)

---------------- = -2

(960-1000)

Formula: y=-2(x-1000)+100

Part B: y=-2(980-1000)+100=140

140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.

Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.

Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.

Find the slope of the line perpendicular to 2x+3y=8

Answers

Answer:

Marissa.

Step-by-step explanation:

To find perpendicular slope you basically take the slope of the given line and reverse whatever sign it had previously. (If it was negative, it would become positive. If it was positive it would become negative.)

By doing -A/B it make the previous slope negative.

Brandon only flipped the fraction which would just result in the slope being slightly steeper, or in this case, less steep than the previous line, rather than making it perpendicular.

Answers

31.41 that the answer

Each of the same-side lengths is 15.67.

What is perimeter?

It is the sum of length of the sides used to made the given figure.

We have been given that the perimeter of a 6-sided figure is 67.74 meters. Two of the sides have the same length. And the sum of the other 4 side lengths is 36.4 meters.

Let the same side be a.

The perimeter of the figure = 6 x side

The perimeter of the figure = 2a + 36.4

67.74 = 2a + 36.4

2a = 67.74 - 36.4

2a = 31.34

a =15.67

Therefore, each of the same-side lengths is 15.67.

In a deli the ratio of ham subs sold to cheese subs sold in a day was 9:4. If 36 cheese subs were sold how many ham subs were sold?

Answers

Answer:

oolollololollolollo

Step-by-step explanation:

The number of ham subs sold is given by the proportion equation A = 81

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the number of ham subs sold be represented as A

Now , the proportion will be

The ratio of ham subs sold to cheese subs sold = 9 : 4

And , the number of cheese subs sold = 36

Substituting the values in the equation , we get

number of ham subs sold A / number of cheese subs sold = 9 / 4

On simplifying the equation , we get

A / 36 = 9 / 4

Multiply by 36 on both sides of the equation , we get

A = ( 9 x 36 ) / 4

A = 9 x 9

A = 81 ham subs

Therefore , the value of A is 81 ham subs

Hence , the number of ham subs sold is 81
