Answer:

  g(x) = (1/6)(x +7)^2 -8

Step-by-step explanation:

The transformation ...

  g(x) = a·f(x -h) +k

represents vertical scaling by a factor of 'a', right shift by h units, and up shift by k units. You want the function g(x) for f(x) = x^2, a = 1/6, h = -7, and k = -8. Those transformations give you ...

  g(x) = (1/6)(x +7)^2 -8

Answer:

[tex]n = 241[/tex]

Step-by-step explanation:

Given

[tex]5x^2 + nx + 48[/tex]

Required

Determine the highest value of n

From the given equation, 5 is a prime number;

So, the factors of x² is 5x and x or -5x and -x

Since [tex]5x^2 + nx + 48[/tex] has all shades of positive terms, we'll make use of 5x and x

The factorized expression can then be:

[tex](5x + a)(x + b)[/tex]

Open the brackets

[tex]5x^2 + ax + 5bx + ab[/tex]

Equate this to the given expression

[tex]5x^2 + ax + 5bx + ab = 5x^2 + nx + 48[/tex]

[tex]5x^2 + (a + 5b)x + ab = 5x^2 + nx + 48[/tex]

By direct comparison;

[tex]5x^2 = 5x^2[/tex]

[tex](a + 5b)x = nx[/tex]

[tex]a + 5b = n[/tex]  ---- (1)

[tex]ab = 48[/tex] --- (2)

From (2) above, the possible values of a and b are:

[tex]a = 1, b = 48[/tex]

[tex]a = 2, b = 24[/tex]

[tex]a = 3, b = 16[/tex]

[tex]a = 4, c = 12[/tex]

[tex]a = 6, b = 8[/tex]

[tex]a = 8, b = 6[/tex]

[tex]a = 12, b = 4[/tex]

[tex]a = 16, b = 3[/tex]

[tex]a = 24, b = 2[/tex]

[tex]a = 48, b = 1[/tex]

Of all these values; the value of a and b that gives the highest value of n is;

[tex]a = 1, b = 48[/tex]

So;

Substitute 1 for a and 48 for b in (2) [tex]a + 5b = n[/tex]

[tex]1 + 5 * 48 = n[/tex]

[tex]1 + 240 = n[/tex]

[tex]241 = n[/tex]

[tex]n = 241[/tex]

Hence, the largest value of n is 241

Answer:

Step-by-step explanation:

The two factors of $5x^2+nx+48$ must be in the form $(5x+A)(x+B)$. $A$ and $B$ must be positive integers to form the largest value of $n$. Therefore, $AB=48$ and $5B+A=n$. To form the largest value of $n$, $B$ must equal $48$. Therefore, $A=1$. \[5B+A=5(48)+1=\boxed{241}\]

Answer:

$450

Step-by-step explanation:

First, write out an equation.  We know that Hannah and Zach together earnes $950 and they get payed in equal hourly rates, so for now, in this step of solving the problem, we will be adding the number of hours each person worked together.

Hannah worked 10 hrs and Zach worked 9 hrs, so add 10+9 to get 19 hrs worked in all between the two of them.

Let "x" represent the amount of money made each hour, and form your equation.

Your equation would be: [tex]19x=950[/tex]

Then, just solve for "x".  Divide both sides by 19.

[tex]\frac{19x}{19}=\frac{950}{19}\\x=50[/tex]

The "x=50" means that Hannah and Zach each earn $50 per hour.

Now, the question asks us to find the amount of money that Zach made.  So, multiply 50 by only the number of hours Zach worked, which is 9.

[tex]50*9=450[/tex]

That means that Zach made a total of $450.

Answer:

0.898

Step-by-step explanation:

The formula for the Coefficient of determination = ratio of explained variation to Total variation

From the above question, we have the following values

Explained variation = 18.592

Total variation = 20.711

The coefficient of determination = 18.592 : 20.711

= 18.592/20.711

= 0.8976872194

Approximately ≈ 0.898

Therefore, the coefficient of determination is 0.898

Answer:

Step-by-step explanation:

Let the number be x

The statement

The square of a number is 3 less than four times the number is written as

x² = 4x - 3

Solve the quadratic equation

We have

x² - 4x + 3 = 0

Write - 4x as a difference

That's

x² - x - 3x - 3 = 0

Factorize the expression

That's

x( x - 1) - 3( x - 1) = 0

( x - 1)( x - 3) = 0

x - 1 = 0 x - 3 = 0

x = 1 x = 3

The numbers are 1 and 3

3 a) Yes The sum of any two sides is larger than the third side

3 b). NO The sum of 3 ft + 4 ft gives 7ft  which is not larger than 10 ft

4 Recall that larger angles opposite larger sides, and smaller angles oppose smaller sides in the triangle. Therefore, the smallest angle must be that opposite the 1 1/4 side that is angle [tex]\angle F[/tex] then angle d must follow (opposes side of length 2) and lastly angle E (since it opposes the largest side of length 2 1/8

Answer:

There are 10 $1 bills and 7 $5 bills

Step-by-step explanation:

7($5 bills) x 5

=35

7+3 (3 more $1 bills)

=10

10+35

=45

Answer:

$1: 10

$5: 7

Step-by-step explanation:

To find out how many of each bill is in the cash box, create an expression

x = the dollar bills

This makes the $5 bills 5x and the $1 bills x (this can also be 1x)

When it says "The number of $1 bills is 3 more than the number of $5 bills" This means that the number of $1 is x + 3 and the number of $5 is 5x

When you put it together the expression will be x + 3 + 5x = 45

First add x and 5x, making it 6x

Next subtract 3 from each side, which makes the equation 6x = 42

Lastly, divide 6 from each side, this means that x = 7

To find out how many bills there are substitute 7 wherever there is an x

This mean that the number of $1 is 7 + 3 (10), and the number of $5 bills are 5x7 (35), but its just 7 because they are $5 each

A. 8.3

B.18.7

C. 10.4

D. 1.04

Step-by-step explanation:

p(x) = 0.03x² + 0.56x + 6.35

A. Determination of p(3)

p(x) = 0.03x² + 0.56x + 6.35

x = 3

p(3) = 0.03(3)² + 0.56(3) + 6.35

p(3) = 0.03(9) + 1.68 + 6.35

p(3) = 0.27 + 1.68 + 6.35

p(3) = 8.3

B. Determination of p(13)

p(x) = 0.03x² + 0.56x + 6.35

x = 13

p(13) = 0.03(13)² + 0.56(13) + 6.35

p(13) = 0.03(169) + 7.28 + 6.35

p(13) = 5.07 + 7.28 + 6.35

p(13) = 18.7

C. Determination of p(13) – p(3)

From A and B above,

p(13) = 18.7

p(3) = 8.3

p(13) – p(3) = 18.7 – 8.3

p(13) – p(3) = 10.4

D. Determination of p(13) – p(3) / 13 – 3

From C above,

p(13) – p(3) = 10.4

p(13) – p(3) / 13 – 3 = 10.4/ 13 – 3

= 10.4 / 10

= 1.04

Answer:

A union B = { 1, 2, 3, 4, 5, 7 }

The A∪B will be {1,2,3,4,5,7}. Then the number of the terms in A∪B will be 6.

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

The union of A and B is given as all the terms in A and B.

Given the following information:

U = {1, 2, 3, 4, 5, 6, 7}

A = {1, 2, 4,5)

B = {1, 3, 5, 7)

Then the A∪B will be given as,

A∪B = 6{1, 2, 3, 4, 5, 7}

Thus, the A∪B will be {1,2,3,4,5,7}.

Then the number of the terms in A∪B will be 6.

Step-by-step explanation:

2.45/2.10 = 1.167 (rounded to the nearest tenth of a cent).

That is, 2.45 is 116.7% of 2.10

Since $2.10 is 100% of 2.10,

2.45 is a 16.7 increase.

The solution is 7.1 %

The percentage increase in the price of the coffee is 7.1 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the percentage increase in the price of the coffee be represented as A

Now , the value of A is calculated by

Let the initial price of the coffee be = P

The value of P = $ 2.10

The increased price of the coffee be = Q

The value of Q = $ 2.25

Now , the equation will be

The percentage increase in the price A = ( increased price of the coffee - initial price of the coffee / initial price of the coffee )  x 100

Substituting the values in the equation , we get

The percentage increase in the price A = ( ( 2.25 - 2.10 ) / 2.10  ) x 100

The percentage increase in the price A = ( 0.15 / 2.10 ) x 100

The percentage increase in the price A = 0.0714 x 100

The percentage increase in the price A = 7.14 %

Therefore , the percentage increase is 7.1 %

Hence , the percentage increase in the price is 7.1 %
