Given the function g ( x ) = x 2 + 10 x + 20 g(x)=x 2 +10x+20, determine the average rate of change of the function over the interval − 9 ≤ x ≤ − 3 −9≤x≤−3.

Answers

Answer 1

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(g(-3) - g(-9)) / (-3 - -9)

g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1

g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11

-3 - -9 = -3 + 9 = 6

(-1 - 11) / 6

-12/6 = -2

the average change rate in this interval is -2 (or fully -2/1).

what is  equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

7- 3√2-x=12

Now solving

7- 3√2-x=12

Subtract 7 from both side

7- 3√2-x - 7 =12 - 7

- 3√2-x = 5

Now, add 3√2 both side

-3√2 -x + 3√2 = 5 + 3√2

-x= 5 + 3√2

x= -(5 + 3√2)

Hence, the value x is -(5 + 3√2).

(y = height; x = number of cups)

Step-by-step explanation:

let x = number of cups

let y = height of the stack

so 9 is the y-intercept

for each additional cup, 1.5 will be added

so y = 1.5x + 9

The formula for calculating the equation of a line is expressed as:

m is the slope

b is the y-intercept

For table 1,

Get the slope:

Use the coordinate (-2, 3) and m = 0 to get the value of "b"

The required function for table 1 is f(x) = 3

For table 2:

Get the slope:  

Use the coordinate (-2, 4) and m = -1 to get the value of "b"

 

The required function for table 2 is g(x) = -x + 2

If the function f(x) = g(x), hence:

-x + 2 = 3

-x = 3 - 2

-x = 1

x = -1

Hence the input value for which f(x) = g(x) is true is -1

Answers

Answer:

(x - 7)(x - 4)(x + 4).            

Step-by-step explanation:

A(x) = x3 – 7x² – 16x +112

Dividing by x-7:

      x^2  - 16               <-------- Quotient

     -----------------------------

x-7)x^3 - 7x^2 - 16x + 112

     x^3 - 7x^2

                    0 - 16x + 112

                        - 16x + 112

                          ..............

so A(x) = (x - 7)(x^2 - 16)       x^2 - 16 is the difference of 2 squares so we have:

(x - 7)(x - 4)(x + 4).

Checking by expanding the brackets:  

(x - 7)(x - 4)(x + 4)

= x(x - 4)(x + 4) - 7(x - 4)(x + 4)

= x(x^2 - 16) - 7(x^2 - 16)

= x^3 - 16x - 7x^2 + 114

= x^3 - 7x^2 - 16x + 112

Whose function has the smaller y-intercept?

Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780

Answers

Answer:

Tim's with a y-intercept of $2,780

Step-by-step explanation:

To find Paul's y-intercept, solve the equation y-1400=56(x+26) for y. Then use the standard format for a linear equation y=mx+b to determine the y-intercept which would be b.

Step 1. Get y by itself by adding 1,400 to both sides.

y-1400 + 1400 = y

56(x+26) + 1400 = 56(x+26) + 1400

New equation y = 56(x+26) + 1400

Step 2. Distribute 56(x+26)

56(x+26) = 56 * x + 56 * 26 = 56x + 1456

New equation y = 56x + 1456 + 1400

Step 3. Simplify.

y = 56x + 2856

Paul's y-intercept would be 2856 because when y=0 x=2856

To Find Tim's y-intercept, subtract 225 * 8 from 4580.

225 * 8 = 1800

4580 - 1800 = 2780

Rosemarie has 16 grandchildren and they will each get 0.50 cents

Answer:

a. Rosemarie has 16 grandchildren.

b. Each grandchild would receive $0.50 or 50 cents.

Step-by-step explanation:

a. There are 4 sons, and each son has 4 children.

Son 1: 4 children

Son 2: 4 children

Son 3: 4 children

Son 4: 4 children

So you can find the total number of grandchildren by adding up the amount of children each of the sons have: 4 + 4 + 4 + 4 = 16

Rosemarie has 16 grandchildren.

b. If the are $8 total, and it is split equally between Rosemarie's sons, it means each son would get $2 (because $8 / 4 sons = 2).

And then each son would split it between his 4 kids. So $2 / 4 kids = $0.50

Each grandchild would receive $0.50 or 50 cents.

sarah has 214 bag of beads each bag has enough beads for 22 bracelets she estimates that since 200x 20 =4,000 there are enough beads for aT LEAST 4000 bracelets tell how how you can critique sarahs reasoning

Answers

Answer:

Sarah's reasoning sounds good to start. She rounded the available bags and their content, so the result, 4000 bracelets, should be really easy to reach.

The exact numbers are 214 bags * 22 bracelets / bag = 4708 bracelets; so as you see, Sarah took care of having room to loose some beads and yet the beads will be enough to make 4000 bracelets.

Of course, if you want to be sure, you should ask Sarah some questions. For example:

1) What proportion of beads are normally deffective?

2) What proportion of beads are normally lost when crafting?

So, if Sarah did not take into account those proportions she migth be overestimating the number of bracelets they can make.

Sarah's assumptions of having enough beads for at least 4000 bracelets is correct.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Sarah who has 214 bag of beads each bag has enough beads for 22 bracelets

According to Sarah, there are enough beads for at least 4000 bracelets.

Mathematically -

x[e] ≥ 4000

Actual number of beads she could make = 22 x 214 = 4708 = x[a]

Since, x[a] > x[e], we can say that Sarah's assumptions are correct.

Therefore, we can say that Sarah's assumptions are correct.

it took jose two-thrids of an hour to complete his math homework on monday,three- fourths of an hour on tuewsday , and two- fifths of an hour on wednesday. how many hours did it take jose to complete his homework altogether

Answers

It took Jose an hour and 49 minutes to complete his homework! (109 minutes)

On Monday, Jose took 2/3 of an hour to complete his math homework. We know that is hour is 60 minutes. Divide 60 by 3 (the denominator) and you get 20. Multiply 20 x 2 (numerator) and you get 40 minutes! 2/3 of an hour is 40 minutes.

On Tuesday, Jose took 3/4 of an hour to complete his homework. Divide 60 by 4 (denominator), and you get 15! Multiply 15 x 3 (numerator) and you get 45. 3/4 of an hour is 45 minutes.

On Wednesday, Jose took 2/5 of an hour to complete his homework. Divide 60 by 5 (denominator), and you get 12. Multiply 12 x 2 (numerator) and you get 24! 2/5 of an hour is 24 minutes.

Finally, you add the three sums of minutes from each day. 40 + 45 + 24 = 109.

Subtract 60 from 109 (109 - 60) and you get a remainder of 49 minutes. This means that it took Jose and hour and 49 minutes to finish his homework.
