A circle has a radius of r inches. The area of a circle is represented by the expression
[tex]3.14 {r}^{2} [/tex]The area of a circle is a function of the radius. Does this situation represent a linear or nonlinear function? Explain
Answer: Nonlinear
Step-by-step explanation: If the exponent is to a power other than 1, it is nonlinnear.
The area of a circle, represented by the expression 3.14r², is a nonlinear function because the area changes in proportion to the square of the radius, demonstrating a quadratic change rather than a linear one.
The area of a circle is a function of the radius, represented by the expression 3.14r². This represents a nonlinear function because the area of the circle does not change at a constant rate with respect to the radius. Instead, the area changes in proportion to the square of the radius, which is a defining characteristic of a quadratic or second-degree polynomial function, not a linear one.
To further illustrate, let's consider a circle with a radius of 1 inch, which would have an area of approximately 3.14 square inches. If the radius is doubled to 2 inches, the area becomes approximately 4 times larger, not double, because the area is 3.14 * (2²) = 3.14 * 4 square inches. This quadratic change demonstrates the nonlinearity of the area function in relation to the radius.
Sue has 7/8 of her book left to read. If she reads another 2/7 of the book how much of the book will she have left?
A 33/56
B 1/5
C 5/8
D 23/40
Answer:
A. 33/56
Step-by-step explanation:
Make them have the same denominator of 56
so you get for the first one 49/56
the second one will be 16/56
subtract both and you get your answer of 33/56
Answer: A. 33/56
Step-by-step explanation:
To get the number of pages left, all we need to do is to subtract 2/7 from 7/8
number of pages left = 7/8 - 2/7
=49 - 16 / 56
= 33/56

Answer:
We will need 5 1/3 lbs of hamburger
Step-by-step explanation:
We can use ratio's to solve this problem. We will put breadcrumbs on top and hamburger on bottom.
1/4 c 1 1/3 c
--------- = -----------
1 lb x lbs
Using cross products
1/4 *x = 1 * 1 1/3
1/4x = 1 1/3
Multiply each side by 4
4 * 1/4 x = 4 * (1 1/3)
x = 4 * 1 1/3
We need to convert 1 1/3 to an improper fraction
1 1/3 = (3*1+1)/3 = 4/3
x = 4 * 4/3
x = 16/3
Now we need to convert it back to a mixed number
3 goes into 16 5 times with 1 left over
x = 5 1/3 lbs

Select Independent or Not independent for each description of events.
P(A)=0.3, P(B)=0.5, P(A|B)=0.15
P(A)=0.2, P(B)=0.4, P(A|B)=0.2
P(A)=0.6, P(B)=0.2, P(A|B)=0.3
Answer:
When two events X and Y are independent,
Then, P(X ∩ Y) = P(X) × P(Y)
We know that,
[tex]P(\frac{X}{Y})=\frac{P(X\cap Y)}{P(Y)}\text{ and }P(\frac{Y}{X})=\frac{P(X\cap Y)}{P(X)}[/tex]
Thus, by substituting the value of P(X ∩ Y),
[tex]P(\frac{X}{Y})=P(X)\text{ and }P(\frac{Y}{X})=P(Y)[/tex]
Which is the required condition for independent events.
In first option,
P(A)=0.3, P(B)=0.5, P(A|B)=0.15
[tex]\implies P(\frac{A}{B})\neq P(A)[/tex]
⇒ A and B are not independent events
In second option,
P(A)=0.2, P(B)=0.4, P(A|B)=0.2
[tex]P(\frac{A}{B})=P(A)[/tex]
⇒ A and B are independent events.
In third option,
P(A)=0.6, P(B)=0.2, P(A|B)=0.3
[tex]\implies P(\frac{A}{B})\neq P(A)[/tex]
⇒ A and B are not independent events
First Part: Not independent
Second Part: Independent
Third Part: Not independent
Two events A and B are independent if:
[tex]P(A|B)=P(A|B') \\Or,P(B|A)=P(B|A')[/tex]
Given,
[tex]P(A)=0.3, P(B)=0.5, P(A|B)=0.15[/tex]
[tex]P(A)=0.2, P(B)=0.4, P(A|B)=0.2[/tex]
[tex]P(A)=0.6, P(B)=0.2, P(A|B)=0.3[/tex]
[tex]P(A\cap B)=P(A|B)P(B)[/tex]
Then by substituting we get,
[tex]P(A|B)=P(A)[/tex] and [tex]P(B|A)=P(B)[/tex]
Computation of First probability:
So, if the probability is independent it will follow the above conditions.
[tex]P(A|B)=0.15\\P(A)=0.3\\0.3\neq 0.15\\ P(A|B)\neq P(A)[/tex]
So, it is not independent
Computation of second probability:
So, if the probability is independent it will follow the above conditions.[tex]P(A|B)=0.2\\P(A)=0.2\\0.2=0.2\\ P(A|B)= P(A)[/tex]
So, it is independent
Computation of second probability:
So, if the probability is independent it will follow the above conditions.
[tex]P(A|B)=0.3\\P(A)=0.6\\0.3\neq 0.6\\ P(A|B)\neq P(A)[/tex]
So, it is not independent.

What is the foil method of (X+3)(x-4)
Answer:
(x-1) x-12
Step-by-step explanation:
Step 1 : Multiply first term of the first bracket to the first term of the other bracket
Step 2 : Then multiply the first term of the first bracket to the last term of the second bracket.
Step 3 : Now come to the second term of first bracket, multiply second term with first term of second bracket.
Step 4 : Finally multiply last term of first bracket with the last term of the second bracket.
Step 5 : Adding all the answers got from the steps, we get the final answer.
Final answer:
The FOIL method is an algebraic technique for multiplying two binomials, represented as (First, Outer, Inner, Last). For the expression (X+3)(x-4), we apply this method to get x^2 - x - 12 after combining like terms.
Explanation:
The FOIL method is a technique used in algebra to multiply two binomials. The acronym FOIL stands for First, Outer, Inner, Last and refers to the order in which you multiply the terms in the binomials. Applying the FOIL method to the expression (X+3)(x-4), we multiply the First terms (x × x), the Outer terms (x × -4), the Inner terms (3 × x), and the Last terms (3 × -4), then sum them all.
Step-by-step, this looks like:
First: x × x = x^2
Outer: x × (-4) = -4x
Inner: 3 × x = 3x
Last: 3 × (-4) = -12
Now, combine these results to get the final expression:
x^2 - 4x + 3x - 12
Combining like terms, we have:
x^2 - x - 12

What is the better buy? 1.50 for 5 oz 1.20 for 3 oz
To find the better buy, calculate the unit price of each item by dividing the cost by the weight, and compare them. The first item at $1.50 for 5 oz has a lower unit price ($0.30 per oz) than the second item at $1.20 for 3 oz ($0.40 per oz), so it is the better buy.
Explanation:To determine which is the better buy between two products, you need to calculate the unit price for each and then compare them.
The unit price is the cost per unit of weight or volume.
Calculate the unit price of the second item: $1.20 for 3 oz means the cost per ounce is $1.20 ÷ 3 oz = $0.40 per oz.Compare the unit prices: The first item has a lower unit price ($0.30 per oz) compared to the second item ($0.40 per oz), making it the better buy.Final answer:
To find the better buy between $1.50 for 5 oz and $1.20 for 3 oz, calculate the cost per ounce for each and compare. The first option is cheaper at $0.30 per ounce compared to the second option at $0.40 per ounce.
Explanation:
To determine which is the better buy between $1.50 for 5 oz and $1.20 for 3 oz, we need to calculate the cost per ounce for each option.
Step-by-step Comparison
Calculate the cost per ounce for the first option: Divide $1.50 by 5 oz to get $0.30 per ounce. Calculate the cost per ounce for the second option: Divide $1.20 by 3 oz to get $0.40 per ounce. Compare the two cost per ounce figures: The first option at $0.30 per ounce is cheaper than the second option at $0.40 per ounce.
Therefore, the better buy is the first option, $1.50 for 5 oz, since it has a lower cost per ounce.
what is the 52nd term for the following sequence ? 14,6,-2,-10,-18
Answer:
[tex]a_{52}[/tex] = - 394
Step-by-step explanation:
these are the terms of an arithmetic sequence with nth term
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1)d
where d is the common difference and [tex]a_{1}[/tex] the first term

Given : Total Number of Games the Team Played = 25
Given : Number of Games won by the Team = 17
[tex]\bf{The\;Percentage\;of\;Team\;Wins = (\frac{17}{25}) \times 100}[/tex]
⇒ The Percentage of Sally's Team Wins = (17 × 4) = 68%
Sally's soccer team played 25 games and the team won 17 games. What percent of games did the team win?
The fraction [tex]\frac{17}{25}[/tex] represents the number of games that Sally's soccer team won out of all the games the team played.
To find what percent of games the team won, we can turn the fraction [tex]\frac{17}{25}[/tex] into a percent.
17 ÷ 25 = 0.68
0.68 × 100 = 68%
Therefore, Sally's soccer team won 68% of the games they played.
Use the substitution method to solve the system of equations. Choose the correct ordered pair.
Answer:
option C (3, 2)
Step-by-step explanation:
We have to solve the system of equation by substitution method.
2x + y = 8 ------(1)
y = -x + 5 -------(2)
Now we substitute the value of y from equation (2) to equation (1)
2x + ( -x + 5) = 8
2x - x + 5 = 8
x + 5 = 8
x = 8 - 5
x = 3
Now from equation (2)
y = -x + 5
y = - 3 + 5
y = 2
Therefore, option C (3, 2) will be the answer.
