Answer:y = 2x + 4

Explanation:

1) The slope - intercept form is of the kind y = mx + b, where m is the slope and b is the y-intercept.

2) Given two points you can find the slope (using the two points) and then the equation using one of the points.

3) slope = m = Δy / Δx

points given (3,10) , (0,4)

m = [y2 - y1] / [x2 - x1] = [10 - 4] / [3 - 0] = 6 / 3 = 2

4) equation

y - y2
-------- = m
x - x2

y - 4
---------- = 2
x - 0

=> y - 4 = 2 (x - 0)

y - 4 = 2x

y = 2x + 4

An ice cream cone has a diameter of 7 cm and a height of 13 cm. How many milliliters of melted ice cream can it hold? (1 cm3 hol

allsm [11]

This question is asking for the volume of the cone.
The formula is 1/3π r²h where r is radius and h is height.
First we must find the radius by dividing the diameter in half, giving us 3.5
Now we plug our values into the formula like this:

1/3 π r²h
1/3 π3.5² 13

This gives us the answer of 166.76mL or 166.8mL depending on how you want to round it.

Hope this helps :)

Solve for X and solve for Y?

Llana [10]

Answer:

$x=3\sqrt 5\\$

$y = \sqrt {126}$

Step-by-step explanation:

By geometric mean property:

$x = \sqrt{9 \times 5} = \sqrt{45} = 3 \sqrt{5} \\ \\ by \: pythagoras \: theorem \\ \\ {y}^{2} = {9}^{2} + {x}^{2} \\ \\ {y}^{2} = {9}^{2} + {(3 \sqrt{5}) }^{2} \\ \\ {y}^{2} = 81 + 45 \\ \\ {y}^{2} = 126 \\ \\ y = \sqrt{126}$

In variogram modeling with multiple variables and anisotropy, if all the variograms cannot be modeled well, it is critical to mo

siniylev [52]

Answer:

The statement is false.

Step-by-step explanation:

If the modeling is with multiple variables it is necessary for all the variables to be modeled well such that the criticality of the model is dependent on all the variograms. It is not dependent on the cross variograms only.
