The cross-section of a ramp is a triangle with side lengths of 9 inches, 40 inches, and 41 inches. Is this a right triangle?

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.

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:

Therefore, the correct table representation of the function f(x)=5*2^x is:

[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:

(-6, 3)

Step-by-step explanation:

What you do is based off the image point (-9, 5). What you do is you go 3 units right which is like -9+3=-6. Then you will go 2 units down which is like 5-2=3.

(-6, 3) is your answer.

The image point of (-9,5) after a translation right 3 units and down 2 units is (-6,3).

We add 3 to the x-coordinate for the right translation and subtract 2 from the y-coordinate for the downward translation.

The image point of (-9,5) after a translation right 3 units and down 2 units can be found by changing the x-coordinate and the y-coordinate according to the translation vectors. Since we are moving right, we add 3 to the x-coordinate, and since we are moving down, we subtract 2 from the y-coordinate. The step-by-step process is:

Translate right 3 units: Add 3 to the x-coordinate (-9). So, -9 + 3 = -6.

Translate down 2 units: Subtract 2 from the y-coordinate (5). So, 5 - 2 = 3.

Therefore, the image point after the translation is (-6,3).

Answer:

41

Step-by-step explanation:

Add the numbers together and divide by 5. 5 is the amount of numbers in the example.

Answer: The mean of all the numbers is 41.

Step-by-step explanation:

To find the mean of a set of numbers you must first add them all together.  In this case, all of the numbers added together equaled 205.  Then, you divide what ever your previous number was by how many numbers are in the original set all total.  In this case, there was 5.  So my last step would be dividing 205 / 5 = 41.  41 is my final answer.

Answer:

The maximum number of points is [tex]140\ points[/tex]

Step-by-step explanation:

we know that

Essay question represent the 10% on Mrs. Moore's English final exam

so

To find the number of points in Essay questions multiply the percent by total questions and then multiply by the value of 10 points each

[tex]10\%=10/100=0.10[/tex]

[tex]0.10*50=5\ Essay\ questions[/tex]

[tex]5*10=50\ points[/tex]

The remaining questions are

[tex]50-5=45\ questions[/tex]

To find the number of points in the remaining questions multiply the number of remaining questions by the value of 2 points each

[tex]45*2=90\ points[/tex]

therefore

The maximum number of points is

[tex]50\ points+90\ points=140\ points[/tex]

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

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.

Answer:

see below

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

Divide the volume by the height to find the area of the base:

3042 / 18 = 169 square cm

Since the base is square both the length and the width are the same,

so find the length take the square root of the base:

Side length = √169 = 13 cm

#5. Simplify 40/8 to 5.  

x = 5.

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

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:

Essentially, 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.

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

I'm sorry but is this a question? I don't mean to be rude.

Step-by-step explanation:

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.

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.

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.
