Nearest to 10, 100,1000 ,10000

Answer: C

Positive and between 0.0 and 0.5

Answer it takes away 2 than adds 3 and takes away 2 than instead of adding 3 on the fourth number it adds 6 so maybe it doubles the number it adds every time or it adds three onto the last number it added with and continues like that.

Answer:

14

Step-by-step explanation:

I tried to put the problem together as best as I could and i got the problem as (6-3x^2-8x^4-2x^3)+(6+7x^2)+(2-7x^3+3x^2)

That means that the constants are 6+6+2.

6+6+2= 14

Answer:

900 phone numbers possible.

Step-by-step explanation:

Given the seven digit numbers are of the form:

FGH-XXXX

Possibilities for F = 3 - 9 and X i.e. 9 possibilities

Possibilities for G = 0 - 9 i.e. 10 digits

Possibilities for H = 0 - 9 i.e. 10 digits

To find:

How many numbers are possible ?

Solution:

This problem is nothing but a problem in which we have to find out how many numbers are possible where each digit has a few options available.

Number of ways to select F = 8 digits from 3 to 9 and 1 alphabet X = 9

Number of ways to select G = 10 digits from 0 to 9

Number of ways to select H = 10 digits from 0 to 9

XXXX part will be same in all the numbers.

So, total phone numbers possible = [tex]9 \times 10 \times 10 = \bold{900}[/tex]

Hence, the answer is:

900 phone numbers possible.

Answer:

Step-by-step explanation:

Hello, as alpha and beta are zeroes of

[tex]x^2-x-2[/tex]

it means that their sum is alpha+beta=1 and their product alpha*beta=-2.

The polynomial whose zeroes are 2 alpha + 1 and 2 beta + 1, means that the sum of its zeroes is 2(alpha+beta)+2=2+2=4

and the product is (2alpha+1)(2beta+1)=4 alpha*beta + 2(alpha+beta) + 1 = 4 * (-2) + 2*(1) +1 = -8 + 2 + 1 = -5. so one of these polynomials is

Answer and Step-by-step explanation: Suppose remaining credit is y and time in minutes is x. To determine a value of y corresponding to a value of x, first find the equation for the function.

Since the function is linear, the equation is of the form: y = mx + b. To determine it:

1) Find slope, or inclination, of the line:

slope (m) = [tex]\frac{y_{b}-y_{a}}{x_{b}-x_{a}}[/tex]

where x's and y's are points of the function.

2) Determine the y-intercept, or b: Use a point of the function, replace them at the equation, y = mx + b, and find b.

3) The equation will be: y = mx + b

With the equation, replace x for the minutes the question is asking and calculate to find the remaining credit.

Th result will be a pair (x,y)

Answer:

-3

Step-by-step explanation:

Solve each piece then use order of operations to solve.

[tex]4^{\frac{1}{2} }[/tex] = 2

[tex]\sqrt[4]{16}[/tex] = 2   so [tex]\frac{2}{\sqrt[4]{16} }[/tex] = [tex]\frac{2}{2}[/tex] = 1

Use the order of operations to finish solving. Multiplication and division come before addition and subtraction.

Answer: C. 15

Step-by-step explanation: You take the total amount that she needs: $1,372.35 and you subtract $200.55. Then you are left with $1171.1. This is the amount that she needs still. Then you take $78.12 and multiply it by 15. You get $1171.8. Then when you add $200.55 and $1171.8 you get $1171.1.

Answer:

Alice reaches 11 metres below the centre as lowest height.

Step-by-step explanation:

Cosine is a bounded function between -1 and 1, so that the lowest height that Alice achieves in Ferris wheel is:

[tex]h(t) = 11\cdot \cos (12\cdot t)[/tex]

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]h(t)[/tex] - Height with respect to centre, measured in metres.

If [tex]\cos (12\cdot t) = -1[/tex], then:

[tex]h_{min} = 11\cdot (-1)[/tex]

[tex]h_{min} = -11\,m[/tex]

Alice reaches 11 metres below the centre as lowest height.

Answer:

2

Step-by-step explanation:

let the number be n, then sum of number and 4 is n + 4 and 3 times the number is 3n, thus

n + 4 = 3n ( subtract n from both sides )

4 = 2n ( divide both sides by 2 )

2 = n

That is the number is 2

Answer:

QC - PB = 6

Step-by-step explanation:

Given PQ is parallel to BC then it divides the sides proportionally, that is

[tex]\frac{AP}{AQ}[/tex] = [tex]\frac{PB}{QC}[/tex] = [tex]\frac{15}{24}[/tex] = [tex]\frac{5}{8}[/tex] , then

[tex]\frac{PB}{QC}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )

8PB = 5QC → *

Given PB + QC = 26 , then

PB = 26 - QC

Substitute into *

8(26 - QC) = 5QC ← distribute left side

208 - 8QC = 5QC ( subtract 5QC from both sides )

208 - 13QC = 0 ( subtract 208 from both sides )

- 13QC = - 208 ( divide both sides by - 13 )

QC = 16

Thus PB = 26 - QC = 26 - 16 = 10

QC - PB = 16 - 10 = 6

Answer:

AB = 17 meters

Step-by-step explanation:

Given that the triangle, ∆ABC, has 2 congruent sides that are indicated with a single marking on segment AC and segment AB, both segments would be of equal measure.

Therefore, since the measure of segment C is 17 meters, the measure of segment AB = measure of segment AC = 17 meters.

Segment AB = 17 meters. It is congruent to segment AC.

Step-by-step explanation:

19x - 7x + 8x = 48 - 8

20x = 40

20x/20 = 40/20

x =2

Answer:

x=2

Step-by-step explanation:

[tex]19x + 8 - 7x = 48 - 8x \\ ⟹ 12x + 8 = 48 - 8x \\ ⟹ 12x + 8x = 48 - 8 \\ ⟹20x = 40 \\ ⟹ x = \frac{40}{20} \\ ⟹x = 2[/tex]

Answer:

60°, 60°, and 60° is the set of interior angles of triangle.

Step-by-step explanation:

Given:

Set of interior angles

Find:

Set of interior angles of triangle

Computation:

We know that, sum of  interior angles of triangle is 180°

So,

90° + 42° + 58° = 190°

60° + 60° + 60° = 180°

100° + 48° + 42° = 190°

31° + 75° + 70° = 176°

So,

60°, 60°, and 60° is the set of interior angles of triangle.

Answer:

[tex]2880\ ft^{3}[/tex]

Step-by-step explanation:

The computation of the total amount of water needed could be determined by using the volume formula which is shown below:

[tex]Volume = L \times W \times D[/tex]

where

L = length,

W = width,

and D = depth.

Now putting the values to the above formula

[tex]Volume = (36\ ft) \times (20\ ft) \times (4\ ft) \\\\= 2880\ ft^{3}[/tex]                            

Therefore, the  total amount of water needed is [tex]2880\ ft^{3}[/tex]

We simply applied the above formula

Answer:

Step-by-step explanation:

A product has a production cost function ​C(x) =165x + 3630 and a revenue function ​R(x)= 220x. Find and analyze the​ break-even quantity, then find the profit function.

Answer:

the break-even  quantity = 66

the profit function = 55x - 3630

Step-by-step explanation:

Given that:

C(x) = 165x + 3630

R(x) = 220 x

The Break-even quantity is C(x) = R(x)

∴

165x + 3630 = 220x

collecting the like terms, we have:

3630 = 220 x - 165 x

3630 = 55 x

[tex]x = \dfrac{3630}{55}[/tex]

x = 66

Thus, the break-even  quantity = 66

The profit function = R(x) - C(x)

The profit function = 220x - 3630 - 165x

By rearrangement

The profit function = 220x - 165x - 3630

The profit function = 55x - 3630

Answer:  5/6x + 1y = -5/3   or       5x + 6y = -10

Step-by-step explanation:

First  you need to write an equation in slope intercept form and convert  it to Standard form. To write an equation in slope intercept form using the coordinates we need to find the slope and the y-intercept.

The slope is the change in y over the change in x.

0-5 = -5

-2-(-8) = 6

Slope  is  -5/6  

  Now find the y intercept   using the formula y =mx + b   where m is the slope and b is the y-intercept.

5 = -5/6(-8) + b

5 = 40/6 +b

-40/6   -40/6

b= -5/3

 So now the equation is  y= -5/6x - 5/3

  So now write it in standard form as  ax+by = c  where x is constant.

 y = -5/6x -5/3

       +5/6x

5/6x + 1y = -5/3  now you can multiply it by 6 to get rid of the fractions.

5/6x(6) + y(6) = -5/3(6)

  5x + 6y = -10
