Given:

For cylinder A:

Radius = 3 unit

Height = 4 unit

For cylinder B:

Radius = 4 unit

Height = 3 unit

To find the ratio of the volume of cylinder A to the volume of cylinder B.

Formula

The volume of a cylinder is,

[tex]V = \pi r^{2} h[/tex]

where, r be the radius and

h be the volume of the cylinder.

Now,

For cylinder A

Putting, r = 3 and h = 4 we get,

Volume [tex]V_{A}[/tex] = [tex]\pi (3^{2} )(4)[/tex]

or, [tex]V_{A} = 36\pi[/tex]

For cylinder B

Putting, r = 4 and h = 3 we get

Volume [tex]V_{B}=\pi (4^{2} )(3)[/tex]

or, [tex]V_{B}= 48\pi[/tex]

Now,

The ratio [tex]\frac{V_{A} }{V_{B}} = \frac{36\pi}{48\pi}[/tex]

or, [tex]\frac{V_{A} }{V_{B}} = \frac{3}{4}[/tex]

Hence,

The ratio of the volume of Cylinder A to the volume of Cylinder B is [tex]\frac{3}{4}[/tex]. Option A

Step-by-step explanation:

1. A is Maxium because it is the highest point on the graph

2.B is Midline because it is the “middle”

3.C is Peroid because the graph in a way ends or meets back in the middle

4.D is Minimum because it is the lowest point on the graph

5.E is Amplitude

Answer:

The number is 6

Step-by-step explanation:

Let the number be x

3 times a number plus 5 =  3x +5

Same number increased by 17 = x + 17

3x + 5 = x + 17

3x -x  + 5 = 17

2x + 5 = 17

2x = 17 - 5

2x = 12

x = 12/2

x = 6

The solution to the problem 3x + 5 = x + 17 is x = 6. This involves setting up an algebraic equation using the given conditions and then solving for x.

This problem seems to be a basic algebra problem. You can begin by setting up the equation based on the sentence given. The sentence translates into the equation: 3x + 5 = x + 17 where x is the unknown number you’re solving for. Then, you need to solve for x by isolating it on one side of the equation.

Step-by-step explanation: Subtract x from both sides of the equation to get 2x + 5 = 17. Then, subtract 5 from both sides to get 2x = 12. Finally, divide by 2 to solve for x. This will give you: x = 6. Therefore, the number that fits the condition in the problem is 6.

The total number of combinations is 2000. Testing each one at a rate of 10 seconds per test would take approximately 20,000 seconds, which is around 6 hours when rounded to the nearest hour.

This problem deals with the concept of combinations in mathematics. To find out how long it would take to try all possible combinations, you first need to determine how many combinations there are. The door code consists of either A or B (2 options) followed by a three-digit code (10 options for each digit, from 0-9). Therefore, there are 2 * 10 * 10 * 10 = 2000 possible combinations. If each combination takes 10 seconds to try, it would take 2000 * 10 = 20,000 seconds. To convert this to hours, divide by 3600 (as there are 3600 seconds in one hour), rounding to the nearest whole number, would give approximately 6 hours.

The other root is 1, and the correct answer is: c. 1

The quadratic equation [tex]x^2 - 3x + a = 0[/tex] has two roots, and given that one of the roots is 2, we can use the fact that the sum of the roots is equal to the coefficient of the linear term (-b/a).  

In this case, the linear term is −3x, so the sum of the roots is 3. Since we know one root is 2, the other root must be such that when added to 2, the sum equals 3.

Therefore, the other root is 3 − 2 = 1.

This demonstrates the application of the sum of roots formula in solving for the other root when one root is known. Hence, the correct answer is 1, which is option (c).

Answer:

42.5

Step-by-step explanation:

so you start with adding 15 to the equations because that is how many days

1.5 15 +20

1.5 x 15 =22.5

22.5+20=42.5

so 42.5 is the answer

The predicted height of the plant 15 days from today is 42.5 cm.

The given expression for the height of a plant is 1.5t + 20, where t represents the number of days from today. To find the predicted height of the plant 15 days from today, we need to substitute t = 15 into the expression.

        height of the plant 15 days from today = 1.5(15)+20 cm

        height of the plant 15 days from today = 22.5 + 20 cm = 42.5 cm

Therefore, the predicted height of the plant 15 days from today is 42.5 cm.

Step-by-step explanation:

[tex]116.5^{3}[/tex]

The approximate total volume of the silo is 116.9 m^3, the correct option is C. 116.5 m^3.

Suppose that the radius of considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

Right circular cylinder is the cylinder in which the line joining center of top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.

We are given that;

Diameter=4.4m

Height=6.2meter

Now,

The radius of the silo is half of its diameter, which is 4.4/2 = 2.2 meters. So, plugging in the given values and using 3.14 for π, we get:

V = πr^2h + (2/3)πr^3

V = 3.14(2.2^2)(6.2) + (2/3)3.14(2.2^3)

V = 94.25 + 22.64

V = 116.89

Therefore, the volume of silo will be 116.5 m^3.

Answer: Elizabeth and Manuel have a distance of 4 meters between them.

Step-by-step explanation: Please refer to the picture attached.

From the information given, Elizabeth is directly behind Hannah and directly left of Manuel. That means we have three points which are HEM, that is, we now have triangle HEM. The longest side (hypotenuse) which is the distance between Hannah and Manuel is given as 5 meters while the other side the distance between Hannah and Elizabeth is given as 3 meters.

We shall apply the pythagoras theorem in solving for the unknown side, EM.

The Pythagoras theorem states thus;

AC² = AB² + BC²

Where AC is the hypotenuse, and AB and BC are the other two sides.

Substituting for the known values, we now have;

5² = 3² + EM²

25 = 9 + EM²

Subtract 9 from both sides of the equation

16 = EM²

Add the square root sign to both sides of the equation

√16 = √EM²

4 = EM

Therefore the distance between Elizabeth and Manuel is 4 meters

Final answer:

To calculate the distance between Elizabeth and Manuel, the Pythagorean theorem is used. Given the 3-meter distance between Hannah and Elizabeth, and the 5-meter distance between Hannah and Manuel, the distance between Elizabeth and Manuel is calculated to be the square root of 34, which is approximately 5.83 meters.

Explanation:

The question pertains to finding the distance between Elizabeth and Manuel, given their respective positions on a stage in relation to Hannah.

To find the distance between Elizabeth and Manuel, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Here, the distances between Hannah and the other two dancers form two sides of a right-angled triangle with Elizabeth and Manuel's positions marking the ends of the hypotenuse.

Since Hannah is 3 meters from Elizabeth and 5 meters from Manuel, we can calculate the distance between Elizabeth and Manuel (hypotenuse) with the following equation:
c^2 = a^2 + b^2

Where c is the distance between Elizabeth and Manuel, a is the distance between Hannah and Elizabeth (3 meters), and b is the distance between Hannah and Manuel (5 meters).

So, c^2 = 3^2 + 5^2 which simplifies to c^2 = 9 + 25, and further to c^2 = 34. This implies that c = [tex]\sqrt{34}[/tex].

Therefore, the distance between Elizabeth and Manuel is the square root of 34, which is approximately 5.83 meters. We can round this to the nearest hundredth for a precise measurement.

The distance between Elizabeth and Manuel is approximately 5.83 meters.

Answer:

67

Step-by-step explanation:

A linear pair is two angles which form a straight angle when combined (or 180 degrees). Thus do 180 - 113 to get 67 degrees for Angle 2

The measure of angle 2 is 67°.

It is required to find the measure of angle 2.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given :

<1=113°

We know that

A linear pair adds to 180 degrees.

<1 + <2 =180°

113°+ <2 = 180°

<2 = 180°-113°

<2 =67°

Answer:

f(x) should shifted Right by 4 units to obtain g(x) ⇒ B

Step-by-step explanation:

Let us put g(x) in the form of g(x) = (x - h)² + k, where h is the the horizontal shift (x - h) to right, (x + h) to left and k is the vertical shift (k) up and (-k) down

In the quadratic function y = ax² + bx + c, h = [tex]-\frac{b}{2a}[/tex]  and k = y at x = h

∵ g(x) = x² - 8x + 1

∵ a is the coefficient of x² and b is the coefficient of x

∴ a = 1 and b = -8

∵ h = [tex]-\frac{b}{2a}[/tex]

∴ h = [tex]-\frac{-8}{2(1)}=\frac{8}{2}[/tex]

∴ h = 4

∵ k = g(x) at x = h

- Substitute x by 4 in g(x) to find k

∴ k = (4)² - 8(4) + 1 = 16 - 32 + 1

∴ k = -15

- Substitute them in the form of g(x) = (x - h)² + k

∴ g(x) = (x - 4)² + (-15)

∵ h is the horizontal shift

∵ (x - h) means shift to right h units

∵ f(x) = x²

∵ g(x) = (x - 4)² + (-15)

- That means f(x) is shifted 4 units to the right

∴ f(x) should shifted right by 4 units to obtain g(x)

Oscar and Eli can sell 368 1-cup servings of lemonade because there are 16 cups in 1 gallon, and they have 23 gallons of lemonade.

Oscar and Eli have prepared 23 gallons of lemonade and want to know how many 1-cup servings they can sell. First, we need to know the equivalent of gallons to cups. There are 16 cups in 1 gallon. Therefore, we multiply 23 gallons by 16 cups per gallon to find the total number of cups available:

23 gallons x 16 cups/gallon = 368 cups. Thus, they can sell 368 1-cup servings of lemonade.

To summarize the conversion:

1. Identify the conversion rate between gallons and cups (1 gallon = 16 cups).

2. Multiply the total gallons of lemonade by the conversion rate to get the total cups (23 gallons x 16 cups/gallon).

The range of the function y=|x-1|+7 is all real numbers greater than or equal to 7, as the absolute value ensures non-negative values to which 7 is added.

The range of the function y=|x-1|+7 can be determined by analyzing the nature of the absolute value function and the constant term. The absolute value function, |x-1|, ensures that the output is always non-negative for any value of x, since it represents the distance from 1 on the number line, which cannot be negative. Therefore, when we add 7 to this non-negative value, the smallest value y can take is when |x-1|=0, which is when x=1. So, at x=1, y will be 7 since we have 0+7. For any other value of x, |x-1| will be positive, and when adding 7, y will be greater than 7. Hence, the range of y is all values greater than or equal to 7.
