Answer:

21.897 to the nearest hundredth is 2.19

Answer:

18

Step-by-step explanation:

If a polynomial f(x) is divided by (x + h) then the remainder is equal to f(- h)

Given

f(x) = x³ + 4x² - 7x - 10 and divided by (x + 4), then the remainder is

f(- 4) = (- 4)³ +4(- 4)² - 7(- 4) - 10 = - 64 + 64 + 28 - 10 = 18

Thus the remainder is 18

The volume of the unused role is 821.34π cm³

Volume is defined as the space occupied within the boundaries of any three-dimensional solid.

Given that is a figure of unused roll of paper towels, we need to find the volume of the unused role,

The volume of a cylinder with radius r and height h is V = π·radius²·height

To find the same we will subtract the volume of the inner cylinder from the outer,

Volume = 6²π(26) - (2.1)²π(26)

= 26(36π - 4.41π)

= 26(31.59π)

= 821.34π cm³

Hence, the volume of the unused role is 821.34π cm³

There are 2300 ways by which we can select 3 students out of 25 students.                        

Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.

Here total number of Students = 25

         Number of selection = 3

Now,

Total number of ways by which we can select 3 out of 25  = ²⁵C₃

                                                                                               = 25!/3!.22!

                                                         = 25 X 24 X 23 X 22! / 3X2X1 X 22!

                                                         = 13800 / 6

                                                         = 2300

Thus, there are 2300 ways by which we can select 3 students out of 25 students.

Answer:

the answer is x>7

Step-by-step explanation:

The solution of the inequality 2x + 6 > 20 is x<7.

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

We have the inequality 2x + 6 > 20.

Now, Subtract 6 from both side we get

2x+ 6 - 6< 20 - 6

2x < 14

Divide both side by 2 we get

2x/2 < 14/2

x< 7

Step-by-step explanation:

Answer: Current will reduce by half

Step-by-step explanation:

The formula for Current is;

Current = Voltage/ Resistance

Say for instance that Voltage is 5 volts and Resistance is 2 ohms. Current will be;

= 5/2

= 2.5 amps

If Voltage is decreased by one half to 2.5 while resistance is held constant, current becomes;

= 2.5/2

= 1.25 amps

Current went from 2.5 to 1.25 amps.

This shows that current will reduce by half if the voltage is decreased by one half while the  resistance is held constant.

D: 2/3x - 13/12 = -5/12x

Step-by-step explanation:

2/3x - 5/6 = -5/12x + 1/4

To simplify, the denominator must be the same. So,

5/6 = 10/12

and 1/4 = 3/12

Then, you move the values to the same side via addition or subtraction.

2/3x (- 10/12 - 3/12) = -5/12x

2/3x - 13/12 = -5/12x

Answer:

  B.  The graph flips over the x-axis

Step-by-step explanation:

When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.

The graph flips over the x-axis.

Attached is an example of a function with its original graph (red) and the graph after being multiplied by -1 (blue). The blue graph is a reflection of the red graph across the x-axis.

Answer:

Step-by-step explanation:

3a-2b=14 multiply by 3

9a - 6b = 42 (1)

4a+3b=13 multiply by 2

8a +6b = 26 (2)

sum up (1) and (2)

17a = 68

a =4

b=-1

Answer:

a = 4 b = -1

Step-by-step explanation:

13 = 4a - 3b  (1)

14 = 3a + 2b  (2)

(1) x 2

(2) x 3

26 = 8a - 6b   (3)

42 = 9a + 6b   (4)

(3) + (4)

68 = 17a

68/17 = 17a/17

a = 4

Substitute back in to original equation

14 = 3(4) - 2b

14 = 12 - 2b

14 - 12 = 12 -12 - 2b

2 = -2b

Divide by -2 both sides

b = -1

Check

3(4) - 2(-1)

12 + 2 = 14
