Kate packs snow into 5 identical jars. Each jar represents a different depth of snow. Kate then lets the snow in each jar comple

tely melt. The table shows the height of the liquid in each jar as it relates to the original depth of snow in the jar.
Which statements are true about the relationship between the depth of the snow and the height of water in the jar after the snow is melted? Check all that apply.

The points on a graph representing the relationship lie on a line.
There is 0.4 inch of water to every 1 inch of snow.
A line through the points will pass through (0, 0).
The function relating snow depth to water depth is quadratic.
The data can be represented by f(x) = 0.2x.

Answer:

A, C, E

Step-by-step explanation:

From the table you can see that the water depth cahnges

0.8-0.4=1.2-0.8=1.6-1.2=2.0-1.6=0.4\ in

for every

4-2=6-4=8-6=10-8=2\ in of snow (option B is false).

This means that the function modelling this situation is linear function (option A is true and option D is false). Let the equation of this function be y=ax+b. Then

0.4=2a+b,\\ \\0.8=4a+b.

Subtract these two equations:

2a=0.8-0.4,\\ \\2a=0.4,\\ \\a=0.2.

Hence,

b=0.4-2\cdot 0.2=0.

The equation of the straight line (the graph of linear function) is y=0.2x. (option E is true) This line passes through the point (0,0), because its coordinates satisfy the equation (option C is true).

Select all correct statements from the relation shown on the graph below.
Free_Kalibri [48]
<h3>Answer:</h3>

after watching a two minute video on how to tell if a relation is a function, I can confidently tell you that the answers are 2, 3, & 4.

<h3>step-by-step explanation</h3><h3></h3>

answers 3 & 4 are the x and y coordinates of the points.

this relation is not a function because it does not pass the vertical line test.

( the vertical line test is where you look at all the vertical lines on the page and check if any of them have multiple dots on them. in this case, the line at x coordinate 1 has dots on both (1, 1) and (1, -1) )

Find the value of x. please helpp
SIZIF [17.4K]

Answer:

A

Step-by-step explanation:

given 2 secants drawn from an external point to the circle , then

the product of the measures of one secant's external part and that entire secant is equal to the product of the other secant's external part and that entire secant, that is

9(9 + 2 + 3x) = 10(10 + 2x + 2)

9(11 + 3x) = 10(12 + 2x) ← distribute parenthesis on both sides

99 + 27x = 120 + 20x ( subtract 20x from both sides )

99 + 7x = 120 ( subtract 99 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3

Four consecutive multiples of 6 yield a sum of 156. What are these multiples?
olga nikolaevna [1]
Let x be the first number:
1st number: = x
2nd consecutive multiple of 6 = x+6
3rd consecutive multiple of 6 = x+12
4rth consecutive multiple of 6 = x+18
Their sum = 156 → x+(x+6)+(x+12)+(x+18) = 156
4x +30 = 156
4x = 120 and x = 30

The numbers are: 30,36,42,48
