Dividing 6x^2 + 26x^2 + 23x + 5 by 3x + 1 using the long division involves the use of groups or parts

The result when 6x^2 + 26x^2 + 23x + 5 is divided by 3x + 1 is 2x^2 + 8x + 5 with no remainder

The dividend is given as:

6x^2 + 26x^2 + 23x + 5

And the divisor is 3x + 1

Divide 6x^3 by 3x:

Result = 2x^2

Multiply 2x^2 by 3x + 1

=> 6x^3 + 2x^2

Subtract 6x^3 + 2x^2 from 6x^3 + 26x^2 + 23x + 5

=>  24x^2 + 23x + 5

Divide 24x^2 by 3x:

Result = 8x

Multiply 8x by 3x + 1

=> 24x^2 + 8x

Subtract 24x^2 + 8x from 24x^2 + 23x + 5

=> 15x + 5

Divide 15x by 3x:

Result = 5

Multiply 5 by 3x + 1

=> 15x + 5

Subtract 15x + 5 from 15x + 5

=> 0

Write out the sum of the results

Result = 2x^2 + 8x + 5

Hence, the result when 6x^2 + 26x^2 + 23x + 5 is divided by 3x + 1 is 2x^2 + 8x + 5 with no remainder

Answer:

y = 7.2

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 10 when x = 25, then

10 = 25k ( divide both sides by 25 )

[tex]\frac{10}{25}[/tex] = 0.4 = k

y = 0.4x ← equation of variation

When x = 18, then

y = 0.4 × 18 = 7.2

Answer and explanation:

The two events of choosing jolly ranchers from each bag, first and second are independent events so the probability of first event AND second event will be multiplied

First bag has 4 red 2 green and one blue

Second bag has 4 red and 2 orange

what is the probability that he would choose a purple jolly rancher from the first bag and a red jolly rancher from the second

Probability = number of favourable outcomes /total number of favourable outcomes

The first bag does not have a purple jolly rancher and so probability is zero

the second bag's probability of choosing a red jolly rancher =4/6

probability of choosing a purple jolly rancher from first bag and red jolly rancher from second bag

=0*4/6=0

Answer=0

Answer:

B

Step-by-step explanation:

3/8 is equal to 0.375, also known as 37.5%.

The experimental probability (as a percent) that she will hit the ball next is 37.5%. Hence, option B is the right choice.

The experimental probability of an event occurring is the number of times it happened during the experiment as a ratio to the number of times the experiment was run.

In the question, we are given that Sarah hit the ball 3 times out of the 8 times.

We are asked to find the experimental probability (as a percent) that she will hit the ball next.

As we know, the experimental probability of an event occurring is the number of times it happened during the experiment as a ratio to the number of times the experiment was run.

∴ The experimental probability = The number of times Sarah hit the ball/The number of times she experimented = 3/8

or, The experimental probability = (3/8)*100 % = (3*25)/2 % = 75/2 % = 37.5%.

∴ The experimental probability (as a percent) that she will hit the ball next is 37.5%. Hence, option B is the right choice.

Step-by-step explanation:

Vertices of the quadrilateral are (-4, 1), (-3, 2), (-1, 2) and (-2, 1).

If the given quadrilateral is dilated by ta scale factor of 1.5 about the origin.

Rule for the dilation,

(x, y) → (kx, ky) [k = scale factor]

New vertices of the quadrilateral after the transformation will be,

(-4, 1) → (1.5×4, 1.5×1)

        → (-6, 1.5)

(-3, 2) → (-4.5, 3)

(-1, 2) → (-1.5, 3)

(-2, 1) → (-3, 1.5)

Now the new points are rotated by 90° clockwise about the origin,

Rule for the rotation of the points,

(x, y) → (y, -x)

So the new vertices will be,

(-6, 1.5) → (1.5, 6)

(-4.5, 3) → (3, 4.5)

(-1.5, 3) → (3, 1.5)

(-3, 1.5) → (1.5, 3)

We can plot these points on the graph to form a new (image) quadrilateral.

Answer:

Number of trucks = 28

Number of cars = 14

Number of SUVs = 46

Total number of vehicles = 88

Step-by-step explanation:

Let T = the number of trucks, C = the number of cars, and S = the number of SUVs washed.

We are told :

They washed twice as many cars as trucks.

Hence: T = 2C

They washed a total of 28 trucks and cars and SUVs

Number of trucks = 28

Number of Cars =

T= 2 C

C = T/2

C = 28/2

C = 14

The number of trucks washed was 2 fewer than half the total number of cars and SUVs washed.

T = 1/2(C + S) - 2

T = 28

C = 14

Hence:

28 = 1/2(14 + S) - 2

28 = 1/2(14) + 1/2(S) - 2

28 = 7 - 2 +S/2

28 - 7 + 2 = S/2

30 - 7 = S/2

23 = S/2

S = 23 × 2

S = 46

Hence, number of SUVs = 46

Total number of vehicles = 28 + 14 + 46

= 88

Answer:

  (c)  $31.75

Step-by-step explanation:

First of all, you need to use some number sense to estimate an answer.

If the $900 loan had no interest, 1/3 of it would be paid off in each of the 3 years, or about $300 each year. You will be making 12 monthly payments each year, so the amount of principal being paid with each payment is $300/12 = $25. Any answer much above this amount will not make sense, so you can immediately reject all choices except $31.75.

__

The simple interest on the loan is ...

  I = Prt = $900×0.09×3 = $243

That, too, is divided among the 36 payments, so adds ...

  $243/36 = $6.75 to each of the $25 payments we calculated above.

The monthly payment is ...

  $25 +6.75 = $31.75

Standard deviation is a measurement of a collection of values' variance or dispersion. The standard deviation of the data set is 2.474.

Step 1: Find the mean

Step 2: Find each score’s deviation from the mean

Step 3: Square each deviation from the mean

Step 4: Find the sum of squares

Step 5: Apply the formula

[tex]SD = \sqrt{\dfrac{\sum(x_i-\bar{x})^2}{n}}[/tex]

The data set that is given to us is {1, 4, 2, 2, 8, 7, 3}, now use the steps to calculate the standard deviation.

Step 1: Find the mean

The mean of the given data set can be written as,

[tex]Mean, \mu=\dfrac{1+4+2+2+8+7+3}{7} = 3.857[/tex]

Step 2: Find each score’s deviation from the mean

1 - 3.857 = -2.857

4 - 3.857 = 0.143

2 - 3.857= -1.857

2 - 3.857= -1.857

8 - 3.857 = 4.143

7 - 3.857 = 3.143

3 - 3.857 = -0.857

Step 3: Square each deviation from the mean

-2.857² = 8.162

0.143² = 0.02

-1.857² = 3.447

-1.857² = 3.447

4.143² = 17.165

3.143² = 9.877

-0.857²= 0.735

Step 4: Find the sum of squares

8.162+0.20+3.447+3.447+17.165+9.877+0.735 = 42.857

Step 5: Apply the formula

[tex]SD = \sqrt{\dfrac{\sum(x_i-\bar{x})^2}{n}}\\\\SD = \sqrt{\dfrac{42.857}{7}} \\\\SD= 2.474[/tex]

Hence, the standard deviation of the data set is 2.474.

Four squares with size of 6 centimeters should be cut to produce the container of greatest capacity.

a) The volume of the box ([tex]V[/tex]), in cubic centimeters, is equal to the area of the base ([tex]A[/tex]), in square centimeters, multiplied by the height of the box ([tex]h[/tex]), in centimeters. The area of the surface is the product of the width ([tex]w[/tex]) and length (l), both in centimeters:

[tex]V = w\cdot l\cdot h[/tex]  

[tex]V = (36-2\cdot x)^{2}\cdot x[/tex]   (1)

The volume of the container is [tex]V = (36-2\cdot x)\cdot x[/tex] cubic centimeters. [tex]\blacksquare[/tex]

b) We need to apply first derivative analysis and second derivative analysis to determine the dimensions of the maximum squares to be cut:

[tex]-4\cdot (36-2\cdot x)\cdot x+(36-2\cdot x)^{2} = 0[/tex]

[tex]-4\cdot x + 36-2\cdot x = 0[/tex]

[tex]6\cdot x = 36[/tex]

[tex]x = 6[/tex]

[tex]V'' (x) = -4\cdot [(-2)\cdot x+(36-2\cdot x)]-4\cdot (36-2\cdot x)\cdot x + (36-2\cdot x)^{2}[/tex]

[tex]V''(x) = 8\cdot x-4\cdot (36-2\cdot x)-4\cdot (36\cdot x-2\cdot x^{2})+(36-2\cdot x)^{2}[/tex]

[tex]V'' (6) = -48[/tex]

Since [tex]V''(6) < 0[/tex], the critical value of [tex]x[/tex] leads to a maximum.

Four squares with size of 6 centimeters should be cut to produce the container of greatest capacity. [tex]\blacksquare[/tex]
