How many unit cubes need to be added to the figure so that it will have a total
volume of 12 cubic units?

Answers

Answer:

c. 4

Step-by-step explanation:

see how many cubes are already there. Then, subtract that answe from 12 to get how many you need.

Answer:

Count the units in total shown here:

There are 2 units both in the back and front.

So double of 2 means 4 units, there are 4 units on the back and front.

Now count the units between them:

There are 4 units across from them.

Add the units together:

4 + 4

= 8, there are 8 units in total shown in this figure.

But, we need to find how many more units should be added to these 8 units to get a result of 12 units altogether.

So, subtract the 8 units from the 12 units to get the remaining units you would need to add to 8 units to get 12.

12 - 8

= 4, you would need 4 more units so that this figure would have a volume of 12.

Answers

C. translated down 2 units

---The "-2" located on the outside of f(x) tells us that the y-values are being changed. With that, the graph can be moved up or down. The presence of the negative/subtraction sign tells us that the graph is moved down.

D. translated right 4 units

---The "-4" located with the x in f(x) tells us that the x-values are being changed. The only tricky thing about this is that the direction of the movement is actually the opposite of the sign. So with the negative/subtraction sign, the graph is moved to the right instead of the left.

Savannah decides to research the relationship between the length in inches and the
weight of a certain species of catfish. She measures the length and weight of a number
of specimens she catches, then throws back into the water. After plotting all her data,
she draws a line of best fit. Based on the line of best fit, what would you predict to be
the length of a catfish that weighed 36 pounds?

Answers

Using the line of best fit, it is found that the predicted length of a catfish that weighed 36 pounds is of 36 inches.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, the line passes through points (20,4) and (29,22), hence the slope is given by:

m = (22 - 4)/(29 - 20) = 2.

Then:

y = 2x + b.

Point (20,4) is replaced in the equation and used to find b, hence:

4 = 2(20) + b

b = -36

Then the equation is given by:

y = 2x - 36.

When the weight is of 36 pounds, x = 36, hence the prediction is of:

y = 2(36) - 36 = 36 inches.

Math question, me need help

Answers

Answer: Idealistically, you can write many numbers here, but for the sake of simplicity, I'll say... -7.60.

Step-by-step explanation: This isn't much in terms of written work, it's more mental math. When we're looking for a number greater than a negtaive number, but it still has to be negative, it will be less than the first number. So, what can be less than -7.81, anything -7.80 and above before you get to -7. The higher the number in the negative scale, the smaller it is. The lower the number on the negative scale, the larger it is. So make the number larger than -7.81, and less than -7.
