(5n2 – 4nm - 9m²) + (7n2 + 4nm +8m²) =

Answers

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]

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

A 400g loaf of white bread contains 228 g of flour. An 800 g loaf of brown
bread contains 472 g of flour. Which loaf contains a higher percentage of flour?

Answers

Answer:

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

Your team wins 24 medals at a competition. The medals are gold, silver, and bronze in a ratio of 1:1:6. How many of each medal did your team win?
gold

Answers

Answer:

3 gold

3 silver

18 bronze

Step-by-step explanation:

Look at the ratio. 1:1:6. Add the numbers together and you get 8 right?

8 × 3 = 24

Now that you know how much to multiply each part of the ratio by, (3, if you didn't get that.) now you multiply.

1 × 3 = 3 Gold

1 × 3 = 3 Silver

6 × 3 = 18 Bronze

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:

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.

What is function?

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.
