A rectangular frame has length (x+2) units and width (x-2) units. If the area is 96 square units, what is the value of x?

Answers

Answer 1

Answer:

x=10

Step-by-step explanation:

according to the question

(x+2)(x-2)=96

=>x^2-4=96

=>x^2=96+4

=>x^2=100

=>x=√100

Therefore

x=10

x=-10

As width and length can't be negative

So x=10

Width=10-2=8

Length=10+2=12

12×8=96 (proven)

Answer 2

Answer:

Please check the explanation.

Step-by-step explanation:

As we know that the area of a rectangle is defined by multiplying the length by the width.

[tex]A=l\times w[/tex]

Given

rectangular frame length = l = (x+2) unitsrectangular frame width = w = (x-2) unitsArea = 96 square units

substituting all the given values in the formula to find the value of x.

[tex]A=l\times w[/tex]

[tex]96=\left(x+2\right)\times \left(x-2\right)[/tex]

[tex]96=x^2-4[/tex]

[tex]x^2-4=96[/tex]

subtract 96 from both sides

[tex]x^2-4-96=96-96[/tex]

[tex]x^2-100=0[/tex]

[tex]x^2=100[/tex]

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

[tex]x=\sqrt{100},\:x=-\sqrt{100}[/tex]

[tex]x=10,\:x=-10[/tex]

Putting x = -10 in the length and width will make the length and width negative, which can not be possible.

i.e.

length = l = x+2 = -10+2 = -8 units

width = w = x-2 = -10-2 = -12 units

Therefore, x=-10 must be excluded.

Now, putting the length of x = 10.

i.e.

length = l = 10+2 = 10+2 = 12 units

width = w = x-2 = 10-2 = 8

[tex]A=l\times w[/tex]

96 = 12 × 8

96 = 96

Therefore, the correct value of x = 10

the first four numbers in a pattern are 4, 2, 1, and 0.5. Find the next three numbers in the pattern.​

Answers

Given:

The first four numbers in a pattern are 4, 2, 1, and 0.5.

To find:

The next three numbers in the pattern.​

Solution:

We have a pattern,

4, 2, 1, 0.5

Clearly, it is a GP and the common ratio is [tex]\dfrac{1}{2}[/tex] because each term is half of its preceding term.

Next term after 0.5 = [tex]0.5\times \dfrac{1}{2}=0.25[/tex]

Next term after 0.25 = [tex]0.25\times \dfrac{1}{2}=0.125[/tex]

Next term after 0.125 = [tex]0.125\times \dfrac{1}{2}=0.0625[/tex]

Therefore, the next three numbers in the pattern are 0.25, 0.125 and 0.0625 respectively.

General admission to Paul’s Pumpkin Patch is $8.00. For children to ride the various rides, they must use tickets that cost $1.00 each. The number of tickets needed for each ride varies. The function for this situation is P(x) = x + 8, where P(x) represents total cost as a function of the number of tickets, x. What is the domain for visiting and riding rides at Paul’s Pumpkin Patch? A. P(x) ≥ $8.00 B. x is all real numbers C. x ≥ 0, where x is non-negative D. x ≥ 0, x is an integer

Answers

Answer:

x ≥ 0, x is an integer

Step-by-step explanation:

Cost of general admission = $8

Cost of 1 ticket = $1

Cost of x tickets = x

So, Total cost for x tickets = x+8

We are given that  P(x) represents total cost as a function of the number of tickets, x

So, P(x)=x+8

Since cost cannot be negative

So, Domain for visiting and riding rides at Paul’s Pumpkin Patch is x ≥ 0, x is an integer

So, Option D is true.

x ≥ 0, x is an integer

Joan Deere sells tractor parts. she gets a base salary of $1255 per month
plus a commission of 8.5% of any sales greater than $10000. She sold $15000 in parts last month. (She only gets commission on the money greater than $10000), How much was her monthly check for?​

Answers

Answer:

$1361.68

Step-by-step explanation:

15000 > 10000

so she gets the 8.5%

so she gets 108.5% of her salary

x/1255 = 108.5/100

1255(108.5) = 136,167.5

136,167.5/100 = 1361.68

3.57x + 1.61 = 4.71 + -2.63x

Reorder the terms:

1.61 + 3.57x = 4.71 + -2.63x

Solving

1.61 + 3.57x = 4.71 + -2.63x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2.63x' to each side of the equation.

1.61 + 3.57x + 2.63x = 4.71 + -2.63x + 2.63x

Combine like terms: 3.57x + 2.63x = 6.2x

1.61 + 6.2x = 4.71 + -2.63x + 2.63x

Combine like terms: -2.63x + 2.63x = 0.00

1.61 + 6.2x = 4.71 + 0.00

1.61 + 6.2x = 4.71

Add '-1.61' to each side of the equation.

1.61 + -1.61 + 6.2x = 4.71 + -1.61

Combine like terms: 1.61 + -1.61 = 0.00

0.00 + 6.2x = 4.71 + -1.61

6.2x = 4.71 + -1.61

Combine like terms: 4.71 + -1.61 = 3.1

6.2x = 3.1

Divide each side by '6.2'.

x = 0.5

Determine if ƒ(x) = –x3 – x4 – 9 + 6x is a polynomial function. If it is, state the degree and the leading coefficient. If not, state why.

Answers

Answer:

The given function is a polynomial function.

The degree of the function is 4 and leading co-efficient is -1.

Step-by-step explanation:

Given function is:

ƒ(x) = –x^3 – x^4 – 9 + 6x

Putting the terms in order of their power.

[tex]f(x) = -x^4-x^3+6x-9[/tex]

A polynomial is an algebraic expression which involves only positive integer exponents for the variables.

A polynomial function is of the form:

[tex]p(x) = a_nx_n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}........ a_0[/tex]

We can see that the function has no negative exponent. So the given function is a polynomial function.

The degree of a polynomial is the highest exponent of variable involved and leading co-efficient is the co-efficient of the variable with highest power.

Hence,

The given function is a polynomial function.

The degree of the function is 4 and leading co-efficient is -1.
