Which expression is equivalent to the given expression (-4abc)3

Answers

Answer:

-64a^3b^3c^3

Step-by-step explanation:

(-4abc)^3= (-4)^3(a)^3(b)^3(c)^3

=-64a^3b^3c^3

Answer:

-12abc

Step-by-step explanation:

Multiply

-4(3) = -12

Since 3 doesn't have any variable such as a, b, or c, then the variable next to -4 doesn't change

Therefore your answer is -12abc

You have 5,814 feet of rope that you need to cut into 27-foot sections. How many sections of rope will you have?a. 215 sections with 8 feet left over
b. 215 sections with 9 feet left over
c. 218 sections with 3 feet left over
d. 215 sections with 3 feet left over

Answers

The answer is d. 215 sections with 3 feet left over

To calculate this, divide the length of the rope (l1) by the length of the section (l2).
n - number of sections

n = l1/l2
l1 = 5,814 ft
l2 = 27 ft

n = 5,814 / 27 = 215.3 sections
215.3 sections can be written as 215 (whole) sections with 3 ft left over.

What is the slope of the line that passes through (3'-7)(-1'1)

Answers

Answer:

Slope of line passing through (3,-7) and (-1,1) = -2

Step-by-step explanation:

The slope of a line passing through points (x₁,y₁) and (x₂,y₂) is given by (y_2-y_1)/(x_2-x_1)

Here points are given by (3,-7) and (-1,1)

So we have (x₁,y₁) = (3,-7) and (x₂,y₂) = (-1,1)

Slope =(1-(-7))/((-1)-3)=(8)/(-4) =-2

Slope of line passing through (3,-7) and (-1,1) = -2
To solve for slope. Remember that slope, m= (change in y)-(change in x). So that means m= (y2-y1)/(x2-x1). Putting in the values we get (1--7)=(1+7)/(-1-3)= (8)/(-4)= -2. So m, or slope is -2.

What is the area of this triangle? And it's not 60, I already checked. PLEASE EXPLAIN!!!!​

Answers

Answer:

A = 4 cm^2

Step-by-step explanation:

The area of a triangle is

A = 1/2 b*h

The base is 4 and the height is 2

A = 1/2 ( 4*2)

A = 1/2*8

A = 4 cm^2

Answer:

4

Step-by-step explanation:

A = BH/2

or Area = Base multiplied by Hieght divided by 2.

(b)4 x (h)2 = 8

8/2 = 4

Let f(x) = -2x^2 and g(x) = 2x - 4. On the set of axes, draw the graphs of y = f(x) andy = g(x).
Using this graph, determine and state all values of x for which f(x) = g(x).

Answers

f(x) = -2x²
g(x) = 2x - 4

                              f(x) = g(x)
                             -2x² = 2x - 4
                       -2x² - 2x = 2x - 2x - 4
                 -2x² - 2x + 4 = -4 + 4
                 -2x² - 2x + 4 = 0
       -2(x²) - 2(x) - 2(-2) = 0
                 -2(x² - x - 2) = 0
                          -2         -2
                      x² - x - 2 = 0
              x² + 2x - x - 2 = 0
x(x) + x(2) - 1(x) - 1(2) = 0
        x(x + 2) - 1(x + 2) = 0
                (x - 1)(x + 2) = 0
   x - 1 = 0    or    x + 2 = 0
     + 1 + 1              -  2 -  2
         x = 1      or       x = -2          
                             f(x) = g(x)
                            -2x² = 2x - 4
                        -2(-2)² = 2(-2) - 4
                           -2(4) = -4 - 4
                                -8 = -8
                                   or
                              f(x) = g(x)
                             -2x² = 2x - 4
                          -2(1)² = 2(1) - 4 
                                -2 = 2 - 4
                                -2 = -2

A research group interested in understanding the effect of listening to classical music on learning mathematics conducted a study. One hundred students were randomly assigned to one of two groups. The first group listened to classical music as they learned a new lesson. The second group learned the same lesson with no music playing. Both groups were tested on the new material to determine how much they learned. The results for the two groups were compared. What kind of study is this?This is an observational study because students were randomly assigned to groups. This is an observational study because a treatment was applied to both groups. This is an experiment because a treatment was applied to a group. This is an experiment because students were able to choose which group to join.
