Answer:  They received  $14.58

Step-by-step explanation:

Set up a proportional relationship

If  2 cents equal to 3 cans then we will represent how  2,187 will be worth by x.

[tex]\frac{0.02}{3} / \frac{x}{2187}[/tex]      Cross multiply

   3x = 43.74    Divide both sides by 3

x = 14.58

There is a multiplicity of 1 for all of them.

Step-by-step explanation:

The required value of a is 3 for the given function.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The function is given as follows:

f(x) = 5x²– 3

Substitute the value of x = x + a in the above function,

f(x + a) = 5(x + a)²– 3

f(x + a) = 5(x² + a² + 2ax) - 3

f(x + a) = 5x² + 5a² + 10ax - 3

f(x + a) = 5x² + 10ax + 5a² - 3    ....(i)

As per the question, we have f(x + a) = 5x²+ 30x + 42     ....(ii)

Equating the equations (i) and (ii),

So, 10a = 30

a = 30/10

a = 3

Therefore, the required value of a is 3.

Answer:

y = 0.14 x^2 - 1.43 x + 10.75

Step-by-step explanation

got it correct on the test

The quadratic function best models this set of data is y = 10.75x² - 1.43x + 0.14.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

We have data shown in the table:

It is required to find the quadratic function best models this set of data.

Let the quadratic function is:

y = ax² + bx + c

We can find the values of a, b, and c from the table,  which are constants.

From the table:

a = 10.75

b = -1.43

c = 0.14

The quadratic function is:

y = 10.75x² - 1.43x + 0.14

Thus, the quadratic function best models this set of data is y = 10.75x² - 1.43x + 0.14.

Answer:

91

Step-by-step explanation:

Answer:

x is 35

Step-by-step explanation:

the two angles are opposite so they are equal

Answer:

x = 35°

Step-by-step explanation:

Vertical Angles

When two lines cross, two pairs of angles are formed. Those who are opposed by the vertex are called vertical angles and they are always congruent.

Congruent angles have the same measure.

Thus, the angle marked as x is opposed to 35° and they have the same measure, thus:

x = 35°

Answer:

$533.33

Step-by-step explanation:

$533.33 multiplied by 0.6 = $319.998 which rounds to $320

533.33 ÷ 100 = 5.33 so this is 1 percent

5.33 x 40 = $213.332 which rounds to $213.33

$320 + $213.33 = $533.33

Answer:

  a) yes; 12/15/17 ~ 20/25/x; SAS

  b) x = 28 1/3

Step-by-step explanation:

The left-side segments are in the ratio ...

  top : bottom = 12 : 8 = 3 : 2

The right side segments are in the ratio ...

  top : bottom = 15 : 10 = 3 : 2

These are the same ratio, and the angle at the peak is the same in both triangles, so the triangles are similar by the SAS postulate.

Normally, a similarity statement would identify the triangles by the labels on their vertices. Here, there are no such labels, so we choose to write the statement in terms of the side lengths, shortest to longest:

  12/15/17 ~ 20/25/x

__

The sides of similar triangles are proportional, so the ratio of longest to shortest sides will be the same in the two triangles. In the smaller triangle, the longest side is 17/12 times the length of the shortest side. The value of x will be 17/12 times the length of the shortest side in the larger triangle:

  x = 17/12 · 20 = 340/12

  x = 28 1/3

Using a linear function, the statement that best describes when she advances to the next phase is: 75 + 3x > 90.

A linear function is modeled by:

y = mx + b

In which:

Considering that she already has 75 points, and earns 3 points for each correct answer, her score is modeled by the following function:

T = 75 + 3x.

She advances to the next phase if she scores over 90 points, hence the statement is:

T > 90

75 + 3x > 90.

u = vector (-6 , -6)

Step-by-step explanation:

u = vector(a , b)

Left (-) 6 units and down (-) 6 units

The translation vector for the image is (-6,-6).

A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. Vectors are given in the form ( x y ) where x is the movement horizontally and y is the movement vertically.

For the given situation,

The image of a point (1, 2) under a translation is (-5, -4) .

The translation vector can be found by calculating the movement horizontally and vertically as

⇒ [tex](-5-1,-4-2)[/tex]

⇒ [tex](-6,-6)[/tex]

Hence we can conclude that the translation vector for the image is (-6,-6).
