Answer:
The radius of the circle is 14 inches.
Step-by-step explanation:
How is the circumference of a circle related to its radius?
[tex]\displaystyle \text{Circumference} = \pi\times \text{Diameter} = \pi\;(2\times \text{Radius})[/tex].
In brief,
[tex]\text{Circumference} = 2\pi\times \text{Radius}[/tex].
For this question,
[tex]\text{Circumference} = 28\pi[/tex], and[tex]\text{Radius}[/tex] needs to be found.Divide both sides of the equation by [tex]2\pi[/tex]:
[tex]\displaystyle \frac{\text{Circumference}}{2\pi} = \text{Radius}[/tex].
[tex]\displaystyle \text{Radius} = \frac{\text{Circumference}}{2\pi} = \frac{28\pi}{2\pi} = 14[/tex].
In other words, the radius of this circle is 14 inches.
when solving the equation which is the best first step to begin to simplify the equation? -2(x+3)=-10
Answer:
c
Step-by-step explanation:
The best first step to solve the equation -2(x+3)=-10 is to distribute the -2 across the parentheses, simplify the equation, and then solve for x.
Checking the answer by substituting the value of x back into the original equation ensures the solution is correct.
Explanation:When solving the equation -2(x+3)=-10, the best first step to simplify the equation is to distribute the multiplication of -2 across the parentheses.
This is done to eliminate the parentheses and simplify the equation into its simplest form. After distribution, you would then have the simplified equation -2x - 6 = -10.
From there, you can proceed to solve for x by adding 6 to both sides of the equation to isolate the term with x, then dividing both sides by -2 to find the value of x.
Here are the basic problem-solving steps:
Distribute the -2 across the parentheses: -2(x+3) becomes -2x - 6.Isolate the variable 'x' by adding 6 to both sides to get -2x = -4.Divide both sides by -2 to find x: x = 2.Once you've calculated the value of x, it's important to check the answer to ensure it is reasonable.
You can do this by substituting the value of x back into the original equation.

What is the pattern in the values as the exponents increase?
Answer:
Option D is correct.
Step-by-step explanation:
We need to find the pattern in the values as the exponents increase.
First value is 1/3
if we multiply 3 with 1/3 i.e. 1/3*3 we get 1
The next value is 1 in the table.
Now, if we multiply 1 with 3 i.e. 1*3 we get 3
The next value is 3 in the table.
Now, if we multiply 3 with 3 i.e 3*3 we get 9
So, the next value is 9 in the table.
So, if we multiply 3 with the previous value we get the next value in the table.
Hence Option D multiply the previous value by 3 is correct.

Write a function for p(x), the profit from selling x necklaces.
The revenue from selling x necklaces is r(x) = 10x. The cost of buying x necklaces is c(x) = 4x + 15. The profit from selling x necklaces is p(x) = r(x) – c(x)
ANSWER
[tex]p(x) = 6x - 15[/tex]
EXPLANATION
The revenue from selling x necklaces is
[tex]r(x) = 10x[/tex]
The cost of buying x necklaces is
[tex]c(x) = 4x + 15[/tex]
The profit from selling x necklaces is
[tex]p(x) = r(x) - c(x)[/tex]
We substitute the functions to get;
[tex]p(x) = 10x- (4x + 15)[/tex]
[tex]p(x) = 10x- 4x - 15[/tex]
[tex]p(x) = 6x - 15[/tex]
Therefore the function for the profit is

a right prism has a square base, a surface area of 512 inches squared, and a height of 12 inches. Find the length of the square base
Answer:
8 inches
Step-by-step explanation:
Surface area of a prism is:
S = 2A + Ph
where A is the area of the base, P is the perimeter of the base, and h is the height of the prism.
The base is a square, so A = s² and P = 4s:
S = 2s² + 4sh
Given that S = 512 and h = 12:
512 = 2s² + 4s(12)
512 = 2s² + 48s
256 = s² + 24s
0 = s² + 24s - 256
0 = (s + 32) (s - 8)
s = -32, s = 8
Since s must be positive, s = 8 inches.
Follow below steps;
To find the length of the square base of the right prism:
First, calculate the lateral surface area: 512 in² = 4s * 12 where s is the side length of the square base.
Then, solve for s: 512 = 48s, s = 512 / 48 = 10.67 in.
Therefore, the length of the square base is 10.67 inches.

Combine the radicals -2/13 + 19/13
Answer:
17/13
Step-by-step explanation:
Answer:
Step-by-step explanation:
" / " indicates "division" and should not be used in this context.
If you meant: -2 square root 13 plus 19 square root 13, the simplest result would be 17 square root 13.
Note that if you click on the "omega" symbol (below), a menu of symbols will appear, including the square root symbol √.
Then: -2√13 + 19√13 = 17√13.
if you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?
Answer:
f(x) = x + 13
Step-by-step explanation:
Given f(x) then f(x) + c represents a vertical translation
• If c > 0 then vertical shift up ↑ of c units
• If c < 0 then vertical shift down ↓ of c units
here c = + 13, hence
f(x) = x + 13

if a = b and c= C, then a + b = b + c
Answer: If [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex]
Step-by-step explanation:
Let be "a", "b", and "c" all real numbers, the Transitive property of equalities states that :
If [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex]
You can observe that if two numbers are equal to the same number, then all this numbers are equal to each other.
For example, applying the Transitive property of equalities to:
[tex]x+3=5[/tex] and [tex]2x+1=5[/tex]
You can equate them:
[tex]x+3=2x+1[/tex]
And solve for "x":
[tex]3-1=2x-x\\\\x=2[/tex]
Answer:
The correct answer option is: If a = b and b = c, then a = c.
Step-by-step explanation:
The Transitive Property of Equality states that if one value, lets say [tex] a [/tex] is equal to another value, call it [tex] b [/tex], which is equal to another value, call it [tex] c [/tex], then the very first value [tex] a [/tex] would be equal to the third value [tex] c [/tex].
So from the given answer options, the correct option is: If a = b and b = c, then a = c.

2x + 3y = 17
5x + 6y = 32
Usibg method if elimination
Answer:
Solution (-2, 7)
Step-by-step explanation:
2x + 3y = 17 (1)
5x + 6y = 32 (2)
Using elimination method
Multiply (-2) to the equation (1)
-4x - 6y = -34
Now you have 2 new equations
-4x - 6y = -34
5x + 6y = 32
----------------------------Add
x = -2
Substitute x = -2 into 2x + 3y = 17
2(-2) + 3y = 17
- 4 + 3y = 17
3y = 21
y = 7
Solution (-2, 7)
Final answer:
The solution to the system of equations 2x + 3y = 17 and 5x + 6y = 32 using the elimination method is x = -2 and y = 7.
Explanation:
To solve the system of equations using the method of elimination, we manipulate the equations to make the coefficients of either x or y the same, and then subtract one equation from the other to eliminate that variable. Let's consider the given equations:
2x + 3y = 17 (Equation 1)
5x + 6y = 32 (Equation 2)
We can see that the coefficients of y are in the ratio of 3:6 or 1:2. To use elimination, we want the coefficients to match, so we can multiply Equation 1 by 2:
(2)(2x) + (2)(3y) = (2)(17)
4x + 6y = 34 (New Equation 1)
Now we can subtract the new Equation 1 from Equation 2:
(5x + 6y) - (4x + 6y) = 32 - 34
5x - 4x + 6y - 6y = -2
x = -2
Now that we have a value for x, we can substitute it back into one of the original equations to solve for y. Let's substitute x into Equation 1:
2(-2) + 3y = 17
-4 + 3y = 17
3y = 17 + 4
3y = 21
y = 7
The solution to the system of equations is x = -2 and y = 7.
How many 5-digit numbers can be formed using the digits 1, 2, 3, 4, 5, 6, 7 if repetition of digits is not allowed?
Answer:
2520
Step-by-step explanation:
7×6×5×4×3 = 2520
Imagine □□□□□
For the 1st □, there are 7 choices
For the 2nd □, there are 6 choices (since 1 out of the 7 numbers is already used)
For the 3rd □, there are 5 choices (since 2 out of the 7 numbers are used)
And so on...
The total number of 5-digit numbers that can be formed with the digits 1 to 7, without repetition, is 2520.
Explanation:Your question pertains to the concept of permutations - the number of ways items can be arranged without repetition. In this case, you are considering how many 5-digit numbers can be formed using the digits 1, 2, 3, 4, 5, 6, 7 without repeating any digit.
A helpful way to think about this is to think of the 5 places for our 5-digit number (i.e., _ _ _ _ _). For the first position, you have 7 choices (the digits 1 to 7) to choose from. Once you have chosen a digit, you are left with 6 choices for the second position, 5 for the third position, 4 for the fourth, and finally 3 for the fifth. So, the total number of 5-digit numbers you can form is 7 × 6 × 5 × 4 × 3 = 2520.

Answer:
x = 5
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
[tex]log_{2}[/tex](3x - 7) = 3, then
3x - 7 = 2³ = 8 ( add 7 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
The required solution of logarithmic expression log2 (3x - 7) = 3 is x = 5. Option B is correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
To solve for x in the equation log2 (3x - 7) = 3, we first use the definition of a logarithm to change the logarithmic form to the exponential form.
log2 (3x - 7) = 3
2³ = 3x - 7
Next, we solve for x by adding 7 to both sides of the equation:
8 + 7= 3x - 7 + 7
15 = 3x
Finally, we divide both sides of the equation by 3:
x = 5
So, the solution of log2 (3x - 7) = 3 is x = 5.

B. The shells of the eggs have cracks in them
c. The shells vary in color
D. The eggs are odorless
When eggs are delivered, if one notices that B. The shells of the eggs have cracks in them, the eggs should be rejected.
Eggs that have cracks in them can be potentially dangerous to people because microorganisms like bacteria can enter through those cracks and either spoil the egg or make it harmful for consumption.
It is therefore best that an egg that has a crack, be rejected upon delivery.
Other options are incorrect because:
One USDA inspection stamp is good enough proof that the eggs are good Shell color has no effect on whether an egg is bad or not Eggs are supposed to be odorlessIn conclusion, if an egg has a crack in it upon delivery, it should be rejected.
