Answer:

coefficient for x : 2

coefficient for y : 3

coefficient for z : -7

Step-by-step explanation:

First of all, we have to organize the polynomials and then sum similar terms:

4x^2         -  6y + 5z + 2

<u>          2x   + 9y - 12z - 2</u>

4x^2 + 2x +3y  - 7z  + 0

Hence by focus on the coefficients that multiplies x, y an z we obtain:

coefficient for x : 2

coefficient for y : 3

coefficient for z : -7

hope this helps!!

Answer:

coefficient of x: 2

coefficient of y: 3

coefficient of z: -7

Step-by-step explanation:

To solve this problem, first we need to sum the polynomials A and B, then we need to check the coefficients of x, y and z.

The sum of the polynomials is:

A + B = 5z + 4x^2 - 6y + 2 + 2x + 9y - 12z - 2

A + B = 4x^2 + 2x + 3y - 7z

So, the coefficients are:

coefficient of x^2: 4

coefficient of x: 2

coefficient of y: 3

coefficient of z: -7

Which situation could be represented by an exponential function select each correct answer
ANTONII [103]

Answer:

The first and third options are the examples of exponential functions.

Step-by-step explanation:

When a quantity is compounded after a certain interval of time at a certain rate, then we can assume that the situation can be represented by an exponential function.

In the first option:  An event organizer finds each year's attendance for the past five years is about \frac{4}{5} of previous year's attendance.

So, here the total attendance is compounding every year by a factor \frac{4}{5} of previous year's attendance.

Again, in the third case: The total population is increasing by about 7.5% each year.

Hence, the population is compounded every year by 7.5% of the previous year's population.

Therefore, the first and third options are examples of exponential functions. (Answer)

How many cubic centimeters of water can this paper cone cup hold?
blagie [28]

48π cm^3

Step-by-step explanation:

The formula for the volume of a cone is...

V=\frac{1}{3}\pi r^2h

We can plug everything we know from the photo into the equation, but note that the picture gives us the diameter, which is 8, instead of the radius. The radius is half of the diameter, so the radius will be 4. Also we will be leaving pi as it is, instead of changing it to 3.14.

V=\frac{1}{3}*(\pi *4*4*9)

V=\frac{1}{3}*(144\pi )

V = 48π

The paper cone can hold <u><em>48π cubic centimeters</em></u> of water.
