Suppose an x-y axis is superimposed on the map with its origin at Des Moines, Iowa. also suppose a cold front is passing through

the US at noon having shaped roughly like a parabola with its vertex at Des Moines, Iowa ad a vertical stretch/ shrink factor of 1/20 if the independent varaible is measured in hundreds of miles. What type of function are you working with. How do you know? Is the leading coefficient positive or negative? how do you know?

Based on the figure and the problem, the cold front is in the shape of a parabola. Therefore, the function is of second degree or a quadratic function. Since the graph of the parabola is curved upwards and its degree is 2 which is even, the leading coefficient is positive.

How to find volume of shape using washer method​
Bond [772]

Answer:

The formula for the volume of a washer requires both an inner radius r1 and outer radius r2. We'll need to know the volume formula for a single washer. V = π (r22 – r12) h = π (f(x)2 – g(x)2) dx. As before, the exact volume formula arises from taking the limit as the number of slices becomes infinite.

Determine whether test point(-7,8) is a solution to the linear inequality x+y<5
ira [324]
False bc if u substitute the values in, -7 + 8, the answer is not less than 5. The answer will be equal to 5, so the test point is not a solution to the linear inequality.

Nancy has to find the reflection of a point across both the x- and the y-axes. Using what you've learned so far about reflection
kifflom [539]

Answer:

Step-by-step explanation:

All she needs to know is that  a reflection across the x-axis is when the x coordinate stays the same and the y-coordinates change.

Hope this helped.

Find the equation of the line that contains the point (15,22)
Svet_ta [14]

Hello from MrBillDoesMath!

Answer:

m = 0

b = 22


Discussion:

I will ignore the duplication of the point (15,22) and "y=mx+b" mentioned in this question.

A line parallel to the x axis is of the form

y = <constant>.

Since the line passes through (15,22), the above constant must be 22. That is,

y = 22 = 0x +22 = mx + b

so m = 0 and b = 22


Thank you,

MrB

How can I solve this? If you can please explain in-depth, thank you.​
Elden [556K]

Step-by-step explanation:

I didn't know this off of the top of my head, and I used Google to help me. Simply searching "30 60 90 right triangle" gave me a few very helpful links. For future reference, if no one is answering here, Google may be your friend.

The (credible) site that I found tells me

"The basic 30-60-90 triangle ratio is:

Side opposite the 30° angle: x

Side opposite the 60° angle: x * √3

Side opposite the 90° angle: 2x"

The side opposite the 30 degree angle is a value called "x" according to this site. This would mean that y is x, which is confusing, so we can just say that the value of y is y (if you want to go a little more in depth, I will simply be referring to what the site refers to as "x" as "y"). To begin, the side opposite the 30 degree angle, which is 8√3, is y * √3. This means that y is 8. Then, the remaining side is 2*y, which is 16.

Please let me know if you have any further questions or concerns.
