A scientist cools some water at a constant rate. The graph and table show
Afina-wow [57]

A function assigns the values. The function for this model can be written as y=-4x+50.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

As it can be seen from the graph that the function is linear, therefore, we can write,

y = mx + c

Given two points of the graph, therefore, we can write for the first point,

30 = m(5) + c

30 = 5m + c

c = 30 - 5m

Also, for the second point,

y = mx + c

26 = 6m + c

Substitute the value of c,

26 - 6m = 30 - 5m

-6m + 5m = 30 - 26

-m = 4

m = -4

Now, substitute the value of m in any one of the equation formed above,

c = 30 - 5m

c = 30 - 5(-4)

c = 50

Hence, the function for this model can be written as y=-4x+50.

Step-by-step explanation:

This is most likely C because it always goes up and although a and c are the only ones with positive equations a makes you multiply by a decimal which can reduce the number so it's most likely C

Which set of coefficients of the terms in the Expansion of the binomial (x+y)^3 is correct?
lora16 [44]
A is correct.

Why? After opening the brackets we can see the equation as x^{3} + 3x^{2}y + 3y^{2}x + y^{3}
