Step-by-step explanation:

The required equation represents the number of bags of sand is b = 4920 ÷ 40.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

here,
To prepare for the winter season the manager of an outdoor ice skating rink ordered 4,920 pounds of sand to keep around the skating rink from being yo slippery One bag of sand is 40 points.
Let the number of bags be b,
40 × = 4920
b = 4920 ÷ 40

Thus, the required equation that represents the number of bags of sand is b = 4920 ÷ 40.

Step-by-step explanation:

The quadratic regression function for the given data function can be written as f(x) = 2.55357143 + 52.8875x - 15.97519841x².

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is that during one game, the Dallas Cowboys punter was called upon to punt the ball eight times. On one of these punts, the punter struck the ball at his own 30-yard line. The height {h} of the ball above the field as a function of time {t} in seconds can be partially modeled by the following table -

{t}       0       0.6      1.2       1.8      2.4     3.0

h{t}   2.50  28.56  43.10  46.12  37.12  17.60

Using the graphing calculator, we can calculate the values as -

Mean of {x} : 1.5

Mean of {y} : 29.16666667

Correlation coefficient {r} : 0.9999376942

A : 2.55357143

B : 52.8875

C : -15.97519841

We can write the quadratic regression function as -

f(x) = A + Bx + Cx²

f(x) = 2.55357143 + 52.8875x - 15.97519841x²

Therefore, the quadratic regression function for the given data function can be written as f(x) = 2.55357143 + 52.8875x - 15.97519841x².

Step-by-step explanation:

50%=14

10%=2.8

4%=1.12

64%=19.92

19.92+28= 45.92

Answer:

66 degrees

Step-by-step explanation:

if there are 66 one degree angles, all alll those together to get 66 degrees in total

The measure of the angle that is given with the given parameter is; 66°

We are told that ang angle is made up of 66 one-degree angles. Now, this means that each of the section of the main angle is one degree.

Thus, the value of 66 numbers of that angle will be;

66 * 1 = 66°

In conclusion, the measure of the angle is 66°.

Step-by-step explanation:

Answer:

Step-by-step explanation:

We know that

The cash cost is $4400.

She pays 10% down

The balance paid in 6

Monthly payment is $676

First , let's find the amount financed:

[tex]A=4400.\frac{90}{100} =3960[/tex]

The number of payments per year (n) are 6.

The time in years is half a year.(6 months)

The installment payment is $676.

The total amount paid is

[tex]676.6=4056[/tex]

Then, we subtract to obtain the finance charge

[tex]4056-3960=96[/tex]

Hence , the answer to (a) is $96, that's the finance charge

Answer:

  a) 3

  b) 1

  c) y = 3x +1

Step-by-step explanation:

Given:

  A(1, 4), B(2, 7)

  m = (y2 -y1)/(x2 -x1)

Find:

  a) the slope of the line through these points

  b) the y-intercept of the line through these points

  c) the equation of the line through these points

Solution:

a) Using the given formula, the slope is ...

  m = (7 -4)/(2 -1) = 3/1 = 3 . . . the slope of the line

__

b) The y-intercept can be found from* ...

  b = y1 -m·x1

  b = 4 -3·1 = 1 . . . the y-intercept

__

c) The equation in slope-intercept form is ...

  y = mx +b

  y = 3x +1

_____

* This equation for the y-intercept is not one you see often. It can be derived from the point-slope form of the equation of a line:

  y -y1 = m(x -x1)

  y = mx -m·x1 + y1 = mx +b . . . . eliminate parentheses, add y1

  b = y1 -m·x1 . . . . . . . . solve for b

Answer:

The new function f(x) = (x-3)² +4

Step-by-step explanation:

Step(i):-

Given that the graph f(x) = x²

The given graph shifted up four units then the  new function

f(x) = x²+4

Step(ii):-

And again the graph shifted '3' units right then the graph is transformed to

f(x) = (x-3)² +4

The loaf of brown bread contains a higher percentage of flour.

Step-by-step explanation:

To find the percentage of flour, we divide the amount of flour by the weight of the bread, and then multiply by 100. So

400g loaf of white bread:

228g of flour

[tex]P = \frac{228*100}{400} = 57\%[/tex]

57% of flour

800g loaf of brown bread:

472g of flour

[tex]P = \frac{472*100}{800} = 59\%[/tex]

59% of flour, so, a higher percentage

Answer:

[tex]\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(5n^2\:-\:4nm\:-\:9m^2\right)\:+\:\left(7n^2\:+\:4nm\:+8m^2\right)[/tex]

Remove parentheses: (a) = a

[tex]=5n^2-4nm-9m^2+7n^2+4nm+8m^2[/tex]

Group like terms

[tex]=5n^2+7n^2-4nm+4nm-9m^2+8m^2[/tex]

Add similar elements: [tex]5n^2+7n^2=12n^2[/tex]

[tex]=12n^2-4nm+4nm-9m^2+8m^2[/tex]

Add similar elements: [tex]-4nm+4nm=0[/tex]

[tex]=12n^2-9m^2+8m^2[/tex]

Add similar elements:  [tex]-9m^2+8m^2=-m^2[/tex]

[tex]=12n^2-m^2[/tex]

Therefore, we conclude that:

[tex]\left(5n^2-4nm-9m^2\right)+\left(7n^2+4nm+8m^2\right)=12n^2-m^2[/tex]
