The volume of the Sphere is  5,575 cm^3.

What is the volume of  the Sphere ?

The volume of the  Sphere  is the capacity it has. It is the space occupied by the sphere.

Formula used to find volume of  the Sphere is :

V = 4/3 × π × r^3

Given : diameter = 22 cm

r = diameter/2  

r = 11 cm

So ,

V = 4/3 × π  × 11 ^3

⇒ 4/3  × π ×  1331

⇒  1.34 × 4179.34

V = 5575.28 cm^3

The nearest cubic unit  is 5,575 cm^3.

Hence , the  volume of the Sphere is  5,575 cm^3 .

Step-by-step explanation:

Answer:

Im working on it right now and its 1

Step-by-step explanation:

To prove that a line is parallel to another, one usually shows that two lines cut by a transversal have either congruent corresponding angles or alternate interior angles. In the lack of perpendicular transversal or angle knowledge, projecting lines onto a new coordinate system can show matching slopes to confirm parallelism.

In mathematics, proving that a constructed line is parallel to a given line typically involves showing that the lines do not intersect and have the same slope or use a parallel postulate. The most common method is taking two lines l and m and a transversal t. If the corresponding angles or alternate interior angles created by t are congruent, then l and m are parallel.

For example: If line l and line m are cut by a transversal t and the corresponding angles (∠1 and ∠2) are congruent, then lines l and m are parallel. The same can be said if the alternate interior angles are congruent.

In some cases, if the transversal line is not perpendicular and we do not know about corresponding or alternate interior angles, we can establish a different coordinate system, project the lines onto the x-axis and y-axis, and show that they have the same slope which proves them to be parallel.

The value of x in equation 5x + 7 = 6x -1 is 8.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

5x + 7 and 6x -1

Now,

The equation is:

5x + 7 = 6x - 1

To solve for x, we need to isolate x on one side of the equation. We can do this by subtracting 5x from both sides and adding 1 to both sides. This gives us:

5x + 7 - 5x = 6x - 1 - 5x

7 + 1 = x - 1 + 1

8 = x

Therefore, by the given equations the answer will be x = 8.

(a)  i. The probability mass function of X is 5 / 14

Hypergeometric Distribution is the probability distribution of a hypergeometric random variable.

The hypergeometric distribution is used to calculate the statistical importance of having drawn a specific k successes (out of n total draws) from the aforementioned population in the hypergeometric test uses.

ii. Please see attached image for the answer.

To find the probability distribution for x, consider the possible values of x and calculate the probability of each value. When 2 marbles are drawn without replacement, there are two possible outcomes. The probability distribution for x is P(x = 0) = 3/28, P(x = 1) = 15/56, and P(x = 2) = 5/14.

To find the probability distribution for x, we need to consider the possible values of x and calculate the probability of each value.

Since there are 5 white marbles and 3 black marbles in the urn, the total number of marbles is 8.

When 2 marbles are drawn without replacement, there are two possible outcomes: (1) both marbles are white and (2) one marble is white and one marble is black.

Let's calculate the probabilities:

P(x = 0) = P(both marbles are black) = (3/8) * (2/7) = 6/56 = 3/28

P(x = 1) = P(one marble is white and one marble is black) = (5/8) * (3/7) = 15/56

P(x = 2) = P(both marbles are white) = (5/8) * (4/7) = 20/56 = 5/14

Therefore, the probability distribution for x is:

P(x = 0) = 3/28

P(x = 1) = 15/56

P(x = 2) = 5/14

The rule for the given sequence (0.5, 0.25, 0, -0.25) is to subtract 0.25 from the previous term. Each consecutive term decreases by 0.25 to form the sequence.

The sequence given is 0.5, 0.25, 0, -0.25. To find the rule of this sequence, look at the differences between terms. Each term is subtracted by 0.25 to get to the next term.

Step-by-Step Explanation:

Therefore, the rule for this sequence is subtracting 0.25 from the previous term to obtain the next term in the sequence.

We are given the functions:

h(t) = -16t^2 + 60t + 95

g(t) = 20 + 38.7t

Part A. All we have to do is to plug in the value of t = 1 to 4 on the two functions

t               h(t)          g(t)

1              139         58.7

2              151         97.4

3              131         136.1

4              79           174.8

Looking at the table, we can say that the time when h(t)=g(t) must be between t=2 and t= 3 seconds
At t=2 seconds h(t) is above g(t), and at t = 3 seconds h(t) is below g(t). Therefore the two functions must be at the same height in between.

Part B. The solution in Part A gives us the exact time where the two objects have the same height. Further, we can see from the table that h(t) is decreasing meaning the projectile is going down while g(t) is increasing so the other projectile is going up.

The dimensions of the rectangle are 10 meters and 6.5 meters

Let the width of the rectangle be represented by w.

The length of the rectangle will then be:

= 2w - 3

Area of the rectangle = 65m²

Note that length × width = Area

Therefore, w × (2w - 3) = 65

2w² - 3w = 65

2w² - 3w - 65 = 0

2w² - 13w + 10w - 65 = 0

2w(w - 6.5) + 10(w - 6.5) = 0

Therefore, w - 6.5 = 0

w = 0 + 6.5

w = 6.5

Width = 6.5 meters

Length = 2w - 3

Length = 2(6.5) - 3

Length = 13 - 3

Length = 10 meters.

The dimensions of the rectangle is 10 meters and 6.5 meters

Compound interest plays a crucial role in determining the final amount of an investment over time, showcasing the power of compounding. In this scenario, with an initial amount of $1,000, an interest rate of 10.1%, and 47 years of compounding annually, the total interest earned would be $91,045.80.

Explanation:

Compound interest is calculated on the principal amount plus the interest earned over time. In this case, with an initial amount of $1,000, an interest rate of 10.1% compounded annually, and an end amount of $92,045.80 after 47 years, compound interest plays a significant role in determining the final amount.

To calculate the total interest earned over the 47 years, you subtract the initial principal amount of $1,000 from the end amount of $92,045.80. This gives you the total interest earned. In this scenario, the total interest earned would be $92,045.80 - $1,000 = $91,045.80.

Compound interest is crucial in understanding how investments grow over time, and it showcases the power of compounding when money is invested wisely and for a long period.

Final answer:

To find out the distance a bat will fly in 15 minutes at an average speed of 32 kilometers per hour, you multiply the speed by the time in hours (15 minutes is 0.25 hours). The bat will fly 8 kilometers.

Explanation:

To calculate how far a bat flies in 15 minutes at an average speed of 32 kilometers per hour, we need to convert the time into hours since the speed is given in kilometers per hour (km/h). 15 minutes is equal to 0.25 hours (since there are 60 minutes in 1 hour, so 15 minutes divided by 60 minutes per hour equals 0.25 hours).

We can then use the formula for distance which is:

Distance = Speed × Time

The average speed of the bat is 32 km/h, and the time is 0.25 hours.

Distance = 32 km/h × 0.25 h = 8 km

So, the bat will fly 8 kilometers in 15 minutes.

The functions representing the areas of the square and circle as functions of the length of one side of the square x are [tex]\[ A_s(x) = x^2 \][/tex] and [tex]\[ A_c(x) = \frac{(10 - x)^2}{4\pi} \][/tex] respectively.

Let's denote:

- [tex]\( x \)[/tex] as the length of one side of the square (in feet).

- [tex]\( 10 - x \)[/tex] as the length of the rope used to form the circle.

1. Area of the Square [tex](\( A_s \))[/tex]:

The area of a square is given by the formula: [tex]\( A_s = x^2 \)[/tex].

2. Area of the Circle [tex](\( A_c \))[/tex]:

The circumference of the circle, formed by the rope, is used to find the radius [tex]\( r \)[/tex] of the circle:

[tex]\[ \text{Circumference} = 2\pi r = 10 - x \][/tex]

Solving for [tex]\( r \)[/tex], we get: [tex]\( r = \frac{10 - x}{2\pi} \)[/tex]

The area of the circle is then given by the formula: [tex]\( A_c = \pi r^2 \)[/tex].

Substituting the value of [tex]\( r \)[/tex], we get:

[tex]\[ A_c = \pi \left(\frac{10 - x}{2\pi}\right)^2 \][/tex]

[tex]\[ A_c = \frac{(10 - x)^2}{4\pi} \][/tex]
