Help with this question, ONLY NEED TO DO NUMBER 5!!

Answer:

See below, sorry for taking so long

Step-by-step explanation:

1.

A. Slope is rise over run or y2 - y1 divided by x2 - x1

We have (-5, 1) and (-3, 7)

7 - 1 / -3 - (-5)

6 / -3 + 5

6 / 2 = 3

Slope = 3

B. So point slope form is y - y1 = m(x - x1)

We know the slope so:

y - 1 = 3(x - (-5))

C. Using the point slope we can move things around to get slope-intercept:

y - 1 = 3(x + 5)

y - 1 = 3x + 15

y - 1 + 1 = 3x + 15 + 1

y = 3x + 16

D. Standard form is Ax + By = C:

y = 3x + 16

y - y = 3x + 16 - y

0 = 3x + 16 - y

0 - 16 = 3x + 16 - y - 16

-16 = 3x - y

3x - y = -16

1.The probability of winning $20 is 1/200.

2.The probability of winning $1500 is 1/7500.

3.The probability of winning $20000 is 1/200000.

4. the probability of not winning anything is 0.9989375

1.The probability of winning $20 is

P(winning) = p(winning chance)/total

                   =1/200.

2.The probability of winning $1500 is

P(winning 1500) = p(winning chance)/total

                           = 1/7500.

3.The probability of winning $20000 is

P(winning) = p(winning chance)/total

                    =1/200000.

4.To find the probability of not winning anything, you can subtract the sum of the probabilities of winning $20, $1500, and $20000 from 1. This is 1 - (1/200 + 1/7500 + 1/200000) = 1 - 0.0010625 = 0.9989375

Probability is a mathematical concept used to measure the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. A probability of 0.5, for example, means that there is an equal chance of an event happening or not happening. In general, the probability of an event can be calculated as the number of favorable outcomes divided by the number of possible outcomes.

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Therefore, after the water cooler is fully filled, there will be about 211.38 gallons of water inside.

Eight pints or 4.564 liters make up a gallon, a unit of liquid or dry capacity.

The cylinder's diameter is specified as 3 feet, so its radius must be half that, or 1.5 feet. The cylinder is described as having a height of 4 feet.

When we enter these values into the formula, we obtain:

V is equal to (1.5)2(4) = 28.26 cubic feet.

We are aware that one cubic foot contains about 7.48 gallons of water. Therefore, we need to multiply the volume of the cylinder by 7.48 to get how many gallons of water are in the water cooler when it is fully filled.

The result of multiplying 28.26 by 7.48 is:

Answer:

a. geometric series

b. r_n = 100 × (0.75)^n ft

c. 400

Step-by-step explanation:

a.

Start: 100 ft

After 1 hour: 75% of 100ft = 100 ft × 0.75

After 2 hours: 75% of 100ft × 0.75 = 100 ft × 0.75²

After 3 hours: 75% of 100 ft × 0.75² = 100 ft × 0.75³

Notice what is happening to the radius as the hours pass.

With each passing hour, the radius is 0.75 times the previous radius.

Since each new term is the previous term multiplied by a constant, 0.75, this is a geometric series.

b.

At each hour, multiply 100 ft by 0.75 raised to the number of the hour.

a_n = 100 × (0.75)^n ft

The nth term is 100 times 0.75 to the nth power.

c.

The sum of all the radii is the sum of a series that has 100 as its first term, and each subsequent term is 0.75 times the previous term.

r_n = 100(0.75)^n

Since the constant ratio has an absolute value less than 1, the series has a sum.

S = a_1/(1 - r)

S = sum of infinite series

a_1 = first term

r = constant ratio

S = 100/(1 - 0.75)

S = 100/0.25

S = 400

The values of the composite functions are (f o g)(x) = 9x² + 5  and (g o f)(x) = 3x² + 15

The definitions of the functions are given as

f(x) = x² + 5 and g(x) = 3x

To find the composite function (f o g)(x), we make use of

(f o g)(x) = f(g(x))

So, we have the following equation

(f o g)(x) = (g(x))² + 5

Substitute g(x) = 3x in (f o g)(x) = (g(x))² + 5

(f o g)(x) = (3x)² + 5

Evaluate the exponent

(f o g)(x) = 9x² + 5

To find the composite function (g o f)(x), we make use of

(g o f)(x) = g(f(x))

So, we have the following equation

(g o f)(x) = 3(f(x))

Substitute f(x) = x² + 5 in (g o f)(x) = 3(f(x))

(g o f)(x) = 3(x² + 5)

Evaluate the exponent

(g o f)(x) = 3x² + 15

Hence, the results are (f o g)(x) = 9x² + 5  and (g o f)(x) = 3x² + 15

It will take approximately 28.67 years for Talwar's investment of R5,800 to grow to R26,100 at a simple interest rate of 12.2% per annum.

To calculate the number of years it will take for Talwar's investment to grow to R26,100 at a simple interest rate of 12.2% per annum, we can use the formula for simple interest:

Simple Interest = Principal × Rate × Time

Given that the principal (P) is R5,800, the rate (R) is 12.2% (or 0.122 as a decimal), and the desired amount (A) is R26,100, we need to find the time (T) it will take. Rearranging the formula, we get:

Time = (Amount - Principal) / (Principal × Rate)

Plugging in the values, we have:

Time = (R26,100 - R5,800) / (R5,800 × 0.122)

= R20,300 / R708.6

≈ 28.67 years

Answer:

The speed of the plane in still air and the speed of the jet stream are 525 miles per hour and 75 miles per hour.

Step-by-step explanation:

From Mechanical Physics, we know that absolute velocity of the airplane (\(v_{A}\)) is equal to sum of the absolute velocity of the jet steam \((v_{J})\) and the relative velocity of the airplane with respect to jet stream (velocity of the airplane in still air) (\(v_{A/J}\)). Al velocities are measured in miles per hour. Let suppose that both jet stream and airplanes travels at constant velocity. Now, we construct the following system of linear equations:

Flight with the jet stream

\(v_{J}+v_{A/J} = \frac{2700\,mi}{4.5\,h}\)

\(v_{J}+v_{A/J} = 600\,\frac{mi}{h}\) (1)

Flight against the jet stream

\(v_{J} -v_{A/J} = -\frac{2700\,mi}{6\,h}\)

\(v_{J}-v_{A/J} = -450\,\frac{mi}{h}\) (2)

The solution of this system of linear equations is:

\(v_{J} = 75\,\frac{mi}{h}\), \(v_{A/J} = 525\,\frac{mi}{h}\)

The speed of the plane in still air and the speed of the jet stream are 525 miles per hour and 75 miles per hour.

Answer:

\(y =\frac{x}{4}\)

Step-by-step explanation:

We are given several functions, and we want to figure out which one is linear.

A linear function has both of its variables (x and y) with a power of 1. Variables with other powers do not mean that the function is linear.

Let's go through the list.

Starting with \(y=\frac{3}{x} -7\), we can see that x is in the denominator. If this is the case, it means that the power of x is -1.

Even though y has a power of 1, this is NOT linear, because x has a power of -1.

Now, with y=√x-2, this is also not linear. This is because √x = \(x^\frac{1}{2}\), even though y has a power of 1.

For x² - 1 = y, we can clearly see that x has a power of 2, while y has a power of 1. This means that the function is not linear.

This leaves us with \(y = \frac{x}{4}\). x is in a fraction, however it is not in the denominator. This means that the power of x in this function is 1. We can also see that the power of y in this function is 1.

This means that \(y=\frac{x}{4}\) is linear.

The missing value for the quadratic function is given as follows:

y = -3.

As a function of it's roots x* and x**, the quadratic function is defined as follows:

y = a(x - x*)(x - x**)

In which a is the leading coefficient.

The roots of the function are the values of x when y = 0, hence:

x* = -4, x** = -2.

Thus:

y = a(x + 4)(x + 2)

y = a(x² + 6x + 8).

When x = 0, y = -8, hence the leading coefficient a of the function is given as follows:

8a = -8

a = -1.

Hence:

y = -x² - 6x - 8;

The missing value is the value of y when x = -1, hence:

y = -(-1)² - 6(-1) - 8

y = -3.

Amount left after buying 3 songs = AED 16.25

Cost of 3 songs = 20 - 16.25 = AED 3.75

Cost per song = \(\frac{3.75}{3}\)

Cost per song = AED 1.25

Cost of 5 songs = 5(1.25) = AED 6.25

Answer:

\(V_2 = 37.5\)

Step-by-step explanation:

Given

\(Volume = 16\)

Represent the height of the smaller cylinder with h and its radius with r.

The height (H) of the larger cylinder is

\(H = h + 50\% * h\)

And the radius (R) is;

\(R = r + 25\% * r\)

Required

Determine the volume of the larger cylinder

Volume of the smaller cylinder is:

\(V_1 = \pi r^2h\)

Substitute 16 for V1

\(16 = \pi r^2h\)

While the volume of the larger cylinder is:

\(V_2 = \pi R^2H\)

We have that:

\(H = h + 50\% * h\) and \(R = r + 25\% * r\)

--------------------------------------------------------------------------------------------------------------

Simplify both expressions

\(H = h + 50\% * h\)

\(H = h + 0.50*h\)

\(H = h + 0.50h\)

\(H = 1.50h\)

\(R = r + 25\% * r\)

\(R = r + 0.25*r\)

\(R = r + 0.25r\)

\(R = 1.25r\)

--------------------------------------------------------------------------------------------------------------

Substitute values for R and H in \(V_2 = \pi R^2H\)

\(V_2 = \pi * (1.25r)^2 * 1.50h\)

\(V_2 = \pi * 1.5625r^2 * 1.50h\)

Collect Like Terms

\(V_2 = 1.50 * 1.5625* \pi*r^2 * h\)

\(V_2 = 2.34375* \pi*r^2 * h\)

\(V_2 = 2.34375* \pi r^2h\)

Recall that: \(16 = \pi r^2h\)

\(V_2 = 2.34375* 16\)

\(V_2 = 37.5\)

Hence, the volume of the larger cylinder is 37.5
