10x^4 - 4x + 6

Explanation:

Just take the width of the rectangle and multiply each number by 2, including the exponent.

Answer & Step-by-step explanation:

We can solve this problem by multiplying the the expression by 2 one term at a time just like it is shown in the diagram. Your exponent will remain the same.

(5x² * 2) + (-2x * 2) + (3 * 2)

10x² - 4x + 6

So, once you multiply th terms togehter, your final answer will (10x²-4x+6)

Answer: D

Step-by-step explanation:

the scale factor is 6

Triangle ABC  has the lengths  4,2,4   and DEF has the lengths 24,12,24

so for the triangle ABC's lengths to become triangle DEF  is is supposed to be multiplied by 6

4*6= 24

2*6= 12

4*6= 24

Answer:

230

Step-by-step explanation:

9 times 20 = 180

divide by 2 = 90

7 times 20 = 140

140 + 90 = 230

Answer:

A=230 cm2

Step-by-step explanation:

A1= L x W             HEIGHT OF TRIANGLE=16-7=9

A1=20 x 7

A1=140 cm2

A2=1/2 x B x H

A2=1/2 x 20 x 9

A2=90 CM 2

Answer:

p = - 5i or p = 5i

Step-by-step explanation:

Noting [tex]\sqrt{-1}[/tex] = i

Given

p² = - 25 ( take the square root of both sides )

p = ± [tex]\sqrt{-25}[/tex] = ± [tex]\sqrt{25(-1)}[/tex] = ± 5i

Thus

p = - 5i or p = 5i

Because p squared is equal to -25, the square root of -25 is equal to p.

Because of this, finding the square root of -25 will give us our answer.

[tex]\sqrt{-25}[/tex] = 5i

Therefore, p = 5i or p = [tex]\sqrt{-25}[/tex].

Hope this helped! :)

Complete Question:

The scatter plot shows the number of oranges picked, in hundreds, in relation to the number of lemons harvested, in hundreds, by several farmers. According to the plot, which value is the best estimate of the correlation coefficient of the data?

A.-0.2

B. -0.9

C. 0.9

D. 0.2

*See attachment for the scatter plot

Answer:

C. 0.9

Step-by-step explanation:

If we take a good look at the scatter plot in the attachment showing numbers if oranges picked in relation to number of lemons harvested, we can infer that there's a strong positive correlation between both variables.

Thus, both variables are moving in the same direction. As one variable increases, the other variable increases. Also, the data points represented on the plot seem clustered close to the line rather than farther away.

This will suggest a positive correlation coefficient that is closer to 1.

From the options given above, the best estimate of the correlation coefficient would be 0.9.

The answer is C. 0.9

Answer:

A

Step-by-step explanation:

A is biased because those people at the grocery store will most likely like that grocery store, since they went there to shop in the first place.

B, C, and D are not biased because there is no correlation between the grocery store and the survey questions.

Option b) going to grocery store and asking people what type of food is their favourite

Answer: m√M = 98°

Step-by-step explanation:

x + x + 6 + 3x - 16 = 180

5x - 10 = 180

5x = 180 + 10

x = 190 / 5 = 38

m√M = 3x - 16

= 3(38) - 16

= 98°

Answer:

m<M = 98 deg

Step-by-step explanation:

Theorem

The sum of the measures of the angles of a triangle is 180 degrees.

Now we set the sum of the measures of the angles equal to 180 and solve for x.

3x - 16 + x + 6 + x = 180

5x - 10 = 180

5x = 190

x = 38

Now that we know x, we substitute x with 38 in the expression for the measure of angle M.

m<M = 3x - 16

m<M = 3(38) - 16

m<M = 114 - 16

m<M = 98

Answer:

x >13/9

Step-by-step explanation:

(1/4)(5x−3) > (1/2)x + (1/3)

Distribute

5/4x - 3/4 > 1/2x + 1/3

Multiply each side by 12 to get rid of fractions

12*5/4x -12* 3/4 >12* 1/2x +12* 1/3

15x -9 > 6x +4

Subtract 6x from each side

15x-6x-9 > 6x-6x+4

9x -9> 4

Add 9 to each side

9x-9+9 > 4+9

9x > 13

Divide by 9

9x/9 >13/9

x >13/9

Answer:

Explanation:

Answer:

x = -(a - b)/b

Step-by-step explanation:

Solve for x:

a = b (1 - x)

a = b (1 - x) is equivalent to b (1 - x) = a:

b (1 - x) = a

Divide both sides by b:

1 - x = a/b

Subtract 1 from both sides:

-x = (a - b)/b

Multiply both sides by -1:

Answer: x = -(a - b)/b

Answer:

x° = ∠OBR = ∠ABC (base angles of a cyclic isosceles trapezoid)

Step-by-step explanation:

APRB form a cyclic trapezoid

∠APO  = x° (Base angle of an isosceles triangle)

∠OPR  = ∠ORP (Base angle of an isosceles triangle)

∠ORB = ∠OBR (Base angle of an isosceles triangle)

∠APO + ∠OPR + ∠OBR = 180° (Sum of opposite angles in a cyclic quadrilateral)

Similarly;

∠ORB + ∠ORP + x°  = 180°

Since ∠APO = x° ∠ORB = ∠OBR and ∠OPR  = ∠ORP we put

We also have;

∠OPR = ∠AOP = ∠BOR (Alternate interior angles of parallel lines)

Hence 2·x° + ∠AOP = 180° (Sum of angles in a triangle) = 2·∠OBR + ∠BOR

Therefore, 2·x° = 2·∠OBR, x° = ∠OBR = ∠ABC.

Answer:

He can work a maximum of 2 8-hour days for the remainder of the week

Step-by-step explanation:

Firstly, from the question, we are made to know that the maximum work hours is 40 hours.

Now, we know that he has already worked 24 hours this week, the number of hours remains to work will be 40-24 = 16 hours

Now, given that his working hour is 8-hours per day, we want to know the number of days he has to work for the remainder of the week

Mathematically, that would be 16 hours divided by 8-hours days

That is 16/8 = 2

Answer: the 5 in the parentheses on the second line should be negative. Also, where did the 23 go?? That's a mistake too.

Step-by-step explanation: 3 - 8 = -5 so

23(2 - 4) + 5(3 - 8)

23(-2) + 5(-5)

(-46) + (-25)

-71

The volume of the given pyramid is 106.1 cubic foot.

Given:

The perimeter of the base is 15.8 feet

The base of the pyramid is square given of side say L .

Thus, from the formula of perimeter of square,

⇒ 4*L = 15.8 feet

∴  L = 3.95 feet

Now the base area of the pyramid is [tex]L^{2}[/tex] as it is a square .

∴ Base area = 3.95*3.95 square feet

= 15.6025 square foot

Now, formula for volume of the pyramid

=  1/3 * base area * height

⇒ Volume = 1/3 * 15.6025 * 20.4 cubic foot

∴ Volume = 106.097 cubic foot

Thus volume of the given pyramid is 106.1 cubic foot rounded off to nearest tenth.

Answer:

89595/100000

Step-by-step explanation:

Answer & Step-by-step explanation:

When we see (f + g)(x), it means that we are adding together f(x) and g(x).

f(x) = 4x + 1

g(x) = x² - 5

(f + g)(x) = (4x + 1) + (x² - 5)

Combine like terms and make sure x² is in the front of the expression so you are following the rules of exponents when in standard form.

(f + g)(x) = x² + 4x - 4

So, (f + g)(x) equals x² + 4x - 4

Answer:

16.485 feet

Step-by-step explanation:

Given that tire is 5.25 feet tall

any circular shape is as tall as its diameter.

we can say that diameter of tire is 5.25 feet.

in one rotation tire will start from one point of tire and reach it again.

it is like on a circle moving from on one point and then reaching to same point.

and we know that distance covered on moving on the point of circle is equal to circumference.

Thus, measure of circumference would help to find how many feet the tractor will travel in 1 rotation.

circumference of circle is given by [tex]\pi D[/tex]

where D is the diameter of circle.

we will us 3.14 as value of [tex]\pi[/tex]

thus, circumference of circle is[tex]\pi * 5.25 = 3.14*5.25 = 16.485[/tex]

Hence, tractor would travel 16.485 feet in one rotation.

Answer: q = 25 m, p = 50 m

Step-by-step explanation:

Answer:

An even number is a number that can be divided into two equal halves.

Also even numbers end in one of these digits: 0, 2, 4, 6, or 8

12 + 12 + 12 + 12 = 48

48 with the digit 8

48 divided in half gives two equal halves:

48/2 = 24

The number 24 can be added twice to check that the answer is correct:

24 + 24 = 48

So to summarize:

The sum of 12 + 12 + 12 + 12 is an even number because it can be equally divided in two halves and it ends in the digit 8.

hope this helps and please make me brainliest if it did :)

Answer:

141

Step-by-step explanation:

We need to first find the volume of the cannonballs and then, divide the volume of the closet by the volume of the cannonballs.

The radius of the spherical cannonball is 0.75 feet.

The volume of a sphere is:

[tex]V = \frac{4}{3} \pi r^3[/tex]

where r = radius

Therefore, the volume of the cannonballs is:

[tex]V = \frac{4}{3} * \pi * 0.75^3\\\\V = 1.77 ft^3[/tex]

Therefore, the number of cannonballs that can fit the closet is:

250 / 1.77 = 141.24

Since the number is a maximum and it must be a whole number, the number of cannonballs that can fit the closet is 141.
