[tex]\bf \textit{volume of a cylinder}\\\\ V = \pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=10\\ h=8 \end{cases}\implies V=\pi (10)^2(8) \\\\\\ V=800\pi \implies V\approx 2513.27[/tex]
Answer:
V = 800π
Step-by-step explanation:
The formula for volume of a cylinder is V = πr²h where r is the radius of the base circle, and h is the height of the cylinder
We are given r = 10, and h = 8. Plug them in and solve for V...
V = π(10²)(8)
V = π(100)(8)
V = 800π
This is the EXACT answer. Leave it in terms of pi. If you multiply out pi, you have to round, then you have an estimated answer.

Answer:
The correct option is 4.
Step-by-step explanation:
The given function is
[tex]f(x)=5(2)^x[/tex]
Put x=0,
[tex]f(0)=5(2)^0=5\times 1=5[/tex]
Put x=1,
[tex]f(1)=5(2)^1=5\times 2=10[/tex]
Put x=2,
[tex]f(2)=5(2)^2=5\times 4=20[/tex]
Put x=3,
[tex]f(3)=5(2)^3=5\times 8=40[/tex]
Only table 4 represents the correct value of the given function, therefore the correct option is 4.
The table representation of the exponential function f(x)=5*2^x is: for x=0, f(x)=5; for x=1, f(x)=10; for x=2, f(x)=20; for x=3, f(x)=40.
Explanation:To find the table representation of the exponential function f(x)=5*2^x, we need to calculate the values of f(x) for different values of x. Remember, any number raised to the power of 2 is being squared, but in this case, x can be any integer, and we're multiplying the result of 2 raised to that power by 5. Here's how you calculate the first few values:
For x=0: f(0) = 5*2^0 = 5*1 = 5 For x=1: f(1) = 5*2^1 = 5*2 = 10 For x=2: f(2) = 5*2^2 = 5*4 = 20 For x=3: f(3) = 5*2^3 = 5*8 = 40
Therefore, the correct table representation of the function f(x)=5*2^x is:
0 - 5 1 - 10 2 - 20 3 - 40

Step-by-step explanation:
Let q = number of quarters
Each quarter is worth .25
The total is 9.50
.25q = 9.50
Divide each side by .25
.25q/.25 = 9.50/.25
q =38
she has 38 quarters
Kevin and Randy Muise have a jar containing 70 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $7.50. How many of each type of coin do they have.
Answer:
50 nickels, 20 quarters.
Step-by-step explanation:
System of equations (q = # of quarters, n = # of nickels):
q + n = 70, 0.25q + 0.05n = 7.50
the first equation can be changed to q = 70 - n, so we are able to substitute q with 70 - n.
So, it will look like 0.25*70 - 0.25n + 0.05n = 7.50. This can be simplified to 0.2n = 10, which means that n = 50.
Knowing that we can solve q + 50 = 70, which means that q = 20.
By applying algebraic principles, it's determined that Kevin and Randy Muise have 20 quarters and 50 nickels. We've used two equations to solve this two-variable problem. The first equation comes from the total number of coins, and the second comes from the total value of the coins
Explanation:The subject of this question is a classic two-variable algebra problem. We have two unknowns here: the number of quarters (which we'll call Q) and the number of nickels (which we'll call N).
From the given information in the question, we can create the following equations:
Q + N = 700.25Q + 0.05N = 7.50Essentially, the first equation states that the total number of coins is 70, and the second equation is representative of the total value in dollars of the coins.
From the first equation, we can isolate one variable: N = 70 - Q.
Substituting this value into the second equation gives us
0.25Q + 0.05(70 - Q) = 7.50
⇒0.20Q +3.50 =7.50
⇒0.20Q= 4
⇒Q= 20
Solving this equation gives us the value of Q (number of quarters) = 20.
Substituting Q = 20 into our first equation: 20 + N = 70, we can find the value of N (number of nickels) = 50.
So, Kevin and Randy Muise have 20 quarters and 50 nickels.

If we know that p → q is true and p is true, what do we know about q?
a. q is false
b. q is true
c. q must be negated
d. q could be either true or false
Answer:
B
Step-by-step explanation:
If p and q are both true, then p→q is true.
If p is true, q is false, then p→q is false.
If p is false, q is true, then p→q is true.
If p and q are both false, then p→q is true.
So if you know that p→q and p are both true, then q must be true (because if q is false, then p→q must be false).

A circular pizza is being made that will fit in a box that is 14 inches by 16 inches. A 2-inch border is needed between the edge of the box and the pizza. What is the radius, in inches, of the largest pizza that can fit in the box?
Now, as the pizza is circular, so it does not matter about the box shape. If the box shape increases or decreases, the pizza shape is the same.
Now, we have been asked about the largest pizza radii that can fit in the box, so we will consider the shortest value of the box.
The width is given as 14 inches. There is a 2 inch border around the pizza. So, the width is 14-4 = 10 inches. (Now assume this as the diameter of pizza)
And the radius is = [tex]\frac{10}{2}=5[/tex] inches.
So, the largest pizza that can fit in the box will have a radius of 5 inches.
Determine the total number of roots of each polynomial function using the factores form? F(x) = (x-6)^2(x+2)^2
Answer:
4
Step-by-step explanation:
If we perform the indicated multiplication, the highest powered x term will be 4 (as in x^4). Thus, the total number of roots of this polynomial will be 4.
Answer:
total number of roots =4
Step-by-step explanation:
the total number of roots of each polynomial function using the factored form
[tex]F(x) = (x-6)^2(x+2)^2[/tex]
Given f(x) is in factored form, to get the roots we look at the factors and the exponents.
[tex](x-6)^2[/tex] has exponent 2, so we have two roots 6 and 6
like that [tex](x+2)^2[/tex] gives us two roots because it has exponent 2
So total number of roots for this polynomial function is 4
What is the area, in square meters, of a right triangle with sides of length 8 meters, 15 meters and 17 meters?
Answer:
60 square meters
Step-by-step explanation:
The area of a triangle is with the formula A = 1/2 b*h. The base and height are the measurements of the sides of a triangle which form a 90 degree angle. When all three measurements are given, the base and height are the smallest since the largest is the hypotenuse. Here b = 8 and h = 15.
So the area is A = 1/2 * 8 * 15 = 60.
What is the probability of rolling a 5 on the first number cube and rolling a 6 on the second number cube? Assume the number cubes are fair and have six sides. Express your answer as a fraction in simplest form.
Answer:
The probability of rolling a 5 on the first number cube and rolling a 6 on the second number cube is 1/36
Step-by-step explanation:
There are total 6 possible outcomes of rolling a six sided fair cube. Therefore, the probability of rolling each number (1,2,3,4,5,6) is fair = 1/6
In this way,
The probability of rolling a 5 on the first number cube = p(A) = 1/6
The probability of rolling a 6 on the second number cube = p(B) = 1/6
The probability of rolling a 5 on the first number cube and rolling a 6 on the second number cube is = p(A) * p(B) = 1/6*1/6 = 1/36
Answer:
1/36
Step-by-step explanation:
The probability of rolling a 5 on the first number cube and rolling a 6 on the second number cube is 1/36
Step-by-step explanation:
There are total 6 possible outcomes of rolling a six sided fair cube. Therefore, the probability of rolling each number (1,2,3,4,5,6) is fair = 1/6
In this way,
The probability of rolling a 5 on the first number cube = p(A) = 1/6
The probability of rolling a 6 on the second number cube = p(B) = 1/6
The probability of rolling a 5 on the first number cube and rolling a 6 on the second number cube is = p(A) * p(B) = 1/6*1/6 = 1/36
Mr Gan has fewer than 20 candies.He wants to pack them into plastic bags.If he packs 3 candies in each bag,he will have 4 extra candies left over.If he packs 5 candies in each bag,he will be short of 2 candies.How many candies does he have?
Answer:
y = 13
Step-by-step explanation:
If Mr Gan packs 3 candies in each bag, he will have 4 extra candies left over. Therefore
3x + 4 = y
where 'x' represents the number of bags, and 'y' the total number of candies he has.
If Mr. Gan packs 5 candies in each bag, he will be short of 2 candies.
5x - 2 = y
To find the number of candies he has, we need to solve the system of equations ove:
3x + 4 = 5x - 2
6 = 2x
x = 3
Now, to find 'y':
5(3) - 2 = y
y = 13
Therefore, Mr. Gan has 13 candies.
Mr. Gan could have 7, 10, 13, or 16 candies.
Explanation:Let's assume that Mr. Gan has x candies.
If he packs 3 candies in each bag, he will have 4 extra candies left over. This means that the total number of candies can be expressed as 3n + 4, where n is the number of bags. Since we know that Mr. Gan has fewer than 20 candies, we can set up the inequality:
3n + 4 < 20
Solving this inequality, we find that n < 5.
If he packs 5 candies in each bag, he will be short of 2 candies. This means that the total number of candies can be expressed as 5m - 2, where m is the number of bags. Using the same reasoning, we can set up the inequality:
5m - 2 < 20
Solving this inequality, we find that m < 4.
Combining the two inequalities, we know that n < 5 and m < 4. Since n and m represent the number of bags, they must be positive integers. So the possible values for n are 1, 2, 3, and 4, and the possible values for m are 1, 2, and 3.
If we substitute these values into the equations, we can find the corresponding number of candies:
If n = 1, then 3n + 4 = 7 candies.
If n = 2, then 3n + 4 = 10 candies.
If n = 3, then 3n + 4 = 13 candies.
If n = 4, then 3n + 4 = 16 candies.
If m = 1, then 5m - 2 = 3 candies.
If m = 2, then 5m - 2 = 8 candies.
If m = 3, then 5m - 2 = 13 candies.
Since Mr. Gan has fewer than 20 candies, the only possible values for the number of candies he has are 7, 10, 13, and 16.

The first five multiples for the numbers 4 and 6 are shown below. Multiples of 4: 4, 8, 12, 16, 20, . . . Multiples of 6: 6, 12, 18, 24, 30, . . . What is the least common multiple of 4 and 6? 2 4 12 24
Answer:
12
Step-by-step explanation:
We are given first five multiples of 4 and 6 as shown below and we are to find their least common multiple.
Multiples of 4: 4, 8, 12, 16, 20, . . .
Multiples of 6: 6, 12, 18, 24, 30, . . .
From the given multiples, we can see that the number 12 and 24 are the common multiples which means that these numbers are multiples of both 4 and 6.
So the least common multiple will be 12.
The least common multiple (LCM) of 4 and 6 is 12. This is the smallest multiple that both numbers share.
Explanation:The least common multiple (LCM) of two numbers is the smallest number that is evenly divisible by both of those numbers. In this case, we are looking for the LCM of 4 and 6.
To find the LCM, we can list the multiples of both numbers and look for the smallest common multiple.
Multiples of 4: 4, 8, 12, 16, 20, ...
Multiples of 6: 6, 12, 18, 24, 30, ...
From the lists, we can see that 12 is the smallest number that appears in both lists. Therefore, the LCM of 4 and 6 is 12.
So, the correct answer is 12. The LCM of 4 and 6 is 12 because it is the smallest number that is evenly divisible by both 4 and 6, as it appears in the list of multiples for both numbers.

The slope of the tangent to a curve at any point (x, y) on the curve is x divided by y. Find the equation of the curve if the point (2, −3) is on the curve. x2 + y2 = 13 x2 + y2 = 25 x2 − y2 = −5 x2 − y2 = 5
[tex]x^2-y^2=-5[/tex]
Step-by-step explanation:The problem tells us that the slope of the tangent to a curve at any point [tex](x, y)[/tex] on the curve is x divided by y, that is:
[tex]m=\frac{x}{y}[/tex]
We also know that the point [tex](2,-3)[/tex] is on the curve. By taking a look on the options this point lies on both equations, namely:
[tex]x^2+y^2=13 \ because \ (2)^2+(-3)^2=13 \\ \\ x^2-y^2=-5 \ because \ (2)^2-(-3)^2=-5[/tex]
We know that the derivative is the slope of the tangent line to the graph of the function at a given point. So taking the derivative of both equations we have:
[tex]\frac{d}{dx}(x^2+y^2)=\frac{d}{dx}(13) \\ \\ \therefore 2x+2y\frac{dy}{dx}=0 \\ \\ \therefore m=\frac{dy}{dx}=-\frac{x}{y}[/tex]
And:
[tex]\frac{d}{dx}(x^2-y^2)=\frac{d}{dx}(-5) \\ \\ \therefore 2x-2y\frac{dy}{dx}=0 \\ \\ \therefore m=\frac{dy}{dx}=\frac{x}{y}[/tex]
So [tex]x^2-y^2=-5[/tex] also meets the requirement of the condition the slope of the tangent to a curve at any point (x, y) on the curve is x divided by y. Therefore this is the correct option.
