A business has a budget of $720 to spend on their marketing campaign. Each month, x, the business spends $40 on different advertisements. The amount of money remaining in the budget
for marketing can be modeled by the function Mx)=-40x+720. Based on the graph of the linear function M(x) and the context of the problem, what is the domain?
O [10, 18]
O [10, 720]
0 [10, 8]
O [R]

Answer:

  28

Step-by-step explanation:

You want the smaller of the two factors of 896 that have the ratio 8:7.

Let x represent the smaller of the two factors (the one we want to find). Then the larger factor is (8/7)x, and their product is ...

  x(8/7)x = 896

  (8/7)x² = 896

Multiplying by the inverse of the coefficient of x², we have ...

  x² = (7/8)(896) = 784

  x = √784 = 28 . . . . . . . . take square root

The smaller of the two numbers is 28.

Additional comment

The larger is (8/7)(28) = 32.

The estimation of the value is A. 40000.

Based on the information, we are to estimate the sum by rounding to the nearest ten thousand. 18,789 + 19,019.

It should be noted that 18789 to the nearest ten thousand is 20000.

Also, 19019 to the nearest ten thousand will be 20000.

Therefore, the addition will be:

= 20000 + 20000

= 40000

The possible numbers that Melody could have picked are -4 and 4.

The operation that prevents us from knowing with 100% certainty the number Melody had picked is multiplication which is implied by the phrase "double the number".

Given, Let x be the number Melody had chosen.

Thus, tripling the number will give 3x, and

squaring this will result to (3x)² which is equals to 9x².

Dividing the square of the number by 2 and subtracting 30 from its quotient will give 42:

9x²/2 ₋ 30 = 42

9x²/2 = 42 ₊ 30

9x²/2 = 72

9x² = 72 × 2

9x² = 144

x² = 144/9

x² = 16

x = ±√16

x = ±4

x = ₊4 or x = 4

hence melody could have picked ₊4 or ₋4 numbers.

Answer:

300 and 30 respectively

Step-by-step explanation:

The 3 in each number can be valued at 3 with the same number of 0s as there are digits to the right of the 3.

For example, in 6300, the 3 stands for 300 because there are two digits (0 and 0) to the right of 3. So we know 3 stands for 300 because we add two 0s to the right of 3.

The scale copy of a shape is the resulting shape when the original shape is dilated. Possible scaled rectangles of rectangle A are 12cm by 8cm and 48cm by 32cm .

It is required to find the measurements that could be the dimensions of rectangle B.

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

Given :

Length=6 cm

width=4cm

According to given question we have,

Divide the length and the width of the rectangle we get=

k=Length/width

k=6/4

k=1.5

This means that a scaled copy of rectangle A must have a value of 1.5

when the dimensions are divided.

Possible rectangles are:

A. 12cm by 8cm

Divide the length and the width of the rectangle we get,

k=12/8

k=1.5

B. 48cm by 32cm

Divide the length and the width of the rectangle we get,

k=48/32

k=1.5

If the axis of symmetry for g(x) is located 2 units to the right of the origin, then the function g(x) = (x-2)2 +k describes this relationship. The best choice would be A in this case.

The function is a statement, rule, or law that specifies the connection between one variable and another variable. It does this by comparing and contrasting the two variables.

Functions may be found almost everywhere, and creating links between physical objects requires their use.

Given

The answer to the question f(x) is.

(x+3)^2 -10

The left side by three units serves as the axis of symmetry for the function f(x).

The axis of symmetry for g(x) may be found five units to the right of where f is located (x).

If this is the case, the axis of symmetry for g(x) will be found 2 units to the right of the origin.

After that, the expression for g(x) will be g(x) = (x-2)2 +k.

Therefore, option A is the one to choose.

Measure of linear pair A and B are 86 and 38 respectively.

Let the measure of  B = x

And measure of  A = 3x – 28

As  A and B are linear pair. Therefore their sum will be equal to 180

That is numerically,

      A + B = 180

Putting the required values of A and B we will get

     3x – 28 + x = 180

      4x  = 180-28

       4x = 152

        x = 38

Hence the measure of A = 3*38 – 28 = 86

And the measure of B = x = 38

Answer:

38.13 m²

Step-by-step explanation:

area of triangle = 1/2 base × height

                          = 1/2 × 4 × 3

                          = 6 m²

Area of rectangle = length ×  width

                             = 6 × 3

                             = 18m²

Area of semi circle = 180/360 × π × radius²

                               = 180/360 × 3.14 × 3²

                               = 14.13 m²

Add all the areas together

The variance and standard deviation for the frequency of pupils per teacher in some states of US is; Variance= 4.62 = 4.6 and Standard Deviation = 2.14 = 2.1

Variance(σ²) is a measure of dispersion. A measure of dispersion is a quantity that is used to check the variability of data about an average value. Data can be of two types - grouped and ungrouped. When data is expressed in the form of class intervals it is known as grouped data.

The standard deviation(σ) of a random variable, is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation.

That means;

Standard Deviation = √variance.

For the given data the sum of frequencies = 1+16+11+7+1+2= 38.

Midpoint is 12,15,18,21,24,27.

ni x mi = 12,240,198,147,24,54.

Sum of ni + mi = 675.

Mean (u) =  17.76

mi - u is -5.76,-2.76,0.24,3.24,6.24,9.24.

(mi - u)² is 33.17,7.61,0.057,10.49,38.93,85.37.

Sum of (mi - u)² = 175.62.

Variance = Sum of (mi - u)² / sum of frequencies

= 175.62/38

= 4.62 = 4.6.

Standard deviation = √variance.

= √4.62

= 2.14 = 2.1.
