Suppose that this grid represents the customer’s yard. The bottom left corner is the origin point, (0, 0), and the x- and y- axes represent the two fences. The rose bush is at point (16, 18).

Answers

Answer 1

The area of the customer's yard is 580π.

What is distance formula?

The distance formula is given as -

d = √(x₂ - x₁)² + (y₂ - y₁)²

Given is that this grid represents the customer’s yard. The bottom left corner is the origin point  O(0, 0), and the x- and y- axes represent the two fences. The rose bush is at point P(16, 18).

We can write the area of the customer's yard -

A = πr²

Here -

r = d

r² = d²

We can write -

A = πd²

A = π {(x₂ - x₁)² + (y₂ - y₁)²}

A = π{16 x 16 + 18 x 18}

A = 580π

Therefore, the area of the customer's yard is 580π.

Answers

False claims do not have to engage with previous theories in order to be effective. So it must contradict previous theories. So the option d is correct.

A tentative, verifiable explanation for a natural world phenomenon is what is known as a scientific hypothesis. The scientific method's foundational element is it.

It's sometimes referred to as a "informed guess" that was made using past knowledge and observation. Despite the fact that this is true, a hypothesis is a better guess.

Creating a hypothesis calls for active observation and background research, in contrast to making a "informed guess," which implies a random prediction based on one's expertise. A hypothesis is predicated on the fundamental tenet that no outcome is predetermined.

whats the parallel equation and perpendicular?

Answers

The equations of the lines are

Parallel lines: y = 4/3x + 2 and y = 4/3x - 2Perpendicular line: y = -0.75x + 8.5

How to determine the equations

The parallel lines

We have the points to be

(3, 6) and (0, 2)

A linear equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 2

Using the points, we have

6 = 3m + 2

So, we have

3m = 4

Divide

m = 4/3

So, the equation is

y = 4/3x + 2

For the other parallel line, we have

y = 4/3x - 2

Perpendicular line

The slopes of parallel and perpendicular lines are opposite reciprocals

So, we have

m = -3/4

This gives

y = -3/4x + c

We have the point to be (0, 8.5)

a jet travels 2964 miles against the wind in 4 hours and 3564 miles with the wind in the same amount of time. what is the rate of the jet in still air and what is the rate of the wind?

Answers

The rate of the jet in still air is 741 mph, and the rate of the wind is 150 mph.

What is rate ?

A rate is a ratio of two quantities, typically a change in one quantity over a corresponding change in another quantity, often over a specific time period. For example, the interest rate on a loan is the ratio of the interest paid to the amount of the loan. A speed is a rate at which an object covers distance, velocity is a rate of change of position, etc.

To find the rate of the jet in still air:

Rate = Distance / Time

The distance is 2964 miles, and the time is 4 hours. So the rate of the jet in still air is:

Rate = 2964 / 4 = 741 mph

To find the rate of the wind, you can use the formula:

Wind Rate = (Distance with wind - Distance against wind) / Time

The distance with the wind is 3564 miles, the distance against the wind is 2964 miles, and the time is 4 hours. So the rate of the wind is:

Wind Rate = (3564 - 2964) / 4 = 600 / 4 = 150 mph

So the rate of the jet in still air is 741 mph, and the rate of the wind is 150 mph.

12. Estimate the average rate of change of p between peak, p(8), and closing, p(14). What is
the meaning of the rate of change in the context of this problem? Show all work.

Answers

The rate of change in this context refers to the change in the value of p, specifically between the peak and closing.This allows us to understand how much p changes on average between these two points in time.

What is the meaning of the rate of change in the context of this problem?

It is a measure of how quickly or slowly the value of p is changing over time.

By calculating the average rate of change, we can understand the overall trend of the value of p and whether it is increasing or decreasing at a steady rate or if there are fluctuations.

This information can be useful for understanding the performance of a stock or investment, as well as predicting future trends.

Additionally, the rate of change can also help to identify any potential issues or opportunities within the market.

Overall, the rate of change provides a clear picture of the stock's performance over a certain period of time.

To calculate the average rate of change of p between peak and closing, we need to find the difference in p values (p(14) - p(8)) and divide that by the difference in time (14 - 8).

p(14) - p(8) = ? - ? = ?

(14 - 8) = ?

The average rate of change of p is ?/6.

The meaning of the rate of change in the context of this problem is the average change in the value of p per unit of time.

In this case, we are looking at the average change in p between the peak and closing, and expressing that change as a ratio of p(14) - p(8) to (14 - 8). This allows us to understand how much p changes on average between these two points in time.

Now, According to the question:

Formula to find the probability of an event:

"P(A) = n(A) / n(S)

where, n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment"

"Information available from the question"

Total number of students are,

n(S) = 10 + 16

n(S) = 26

Let event A: selecting first stick with a boy name

n(A) = 16

So, the probability of a boy is,

P(A) = n(A)/n(S)

P(A) = 16/26

P(A) = 8/13

if the first stick is not replaced, then n(S) would be,

26 - 1 = 25

Let event A: selecting first stick with a boy name

n(B) = 10

So, the probability of a boy is,

P(B) = n(B)/n(S)

P(B) = 10/25

P(B) = 2/5

In a connection that is represented by an exponential function, the independent variable's proportional change is unchanged with a constant change in the independent variable.

Explain about the exponential function?

Calculating the exponential growth or decay of a given collection of data is done using an exponential function, which is a mathematical function. Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread.

When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x.

After x hours, you will have twice as much germs if you start with one and it doubles every hour. F(x) = 2x can be used to express this.

The fundamental exponential function generally has the shape,

y = nakx-------

(0,3) is the function's y intercept.

This location has to satisfy the equation (1). So let's substitute in order to get,

3 = na k(0)

⇒ 3 = n x a 0

⇒ 3 = n x 1

⇒ n = 3

Our equation 1 now changes.

y = nakx-------

Noting that the graph crosses through,(1 ,1) it must also satisfy its equation because it does so. Equation (2) can be solved by substituting this point, giving us

C = πD

Where C = Circumference

R = radius

D = Diameter which is 2r

π = 3.14

To arrive at how many rotations each tire did, we'd have to divide the distance traveled by the circumference of each tire.

For the Small Tire, the diameter is 9 feet.

Thus, the circumference of Small Tire = 3.14 * 9

= 28.26 feet

Thus, the rotations by the small tire is:

600/28.26

= 21.2314225053

[tex]\approx[/tex] 21.2feet

Applying the same process to the big tire, we have:

C =  3.14 * 60

C = 188.4

The rotations by the big tire =
600/188.4

= 3.1847133758

[tex]\approx[/tex] 3.2 feet.

Thus, the rotations  by each tire over 600ft is given as:

Big Tire = 3.2

Small Tire =  188.4 .

what is the value of x in 12 ( x + 10 ) = 24

also explain

Answers

Answer: x = -8

Step-by-step explanation:

12 ( x + 10 ) = 24

First we divide the two sides of the exercise by 12.

[tex]\boldsymbol{\sf{x+10=\dfrac{24}{12} }}[/tex]

We divide 24 by 12..

x + 10 = 2

Subtract 10 from both sides.

x = 2 - 10

Subtract 10 from 2 to get. Since the number 10 is greater than 2, the result will be negative.

x = -8

Answer:

[tex] \sf \: x = - 8[/tex]

Step-by-step explanation:

Given equation,

→ 12(x + 10) = 24

Now the value of x will be,

→ 12(x + 10) = 24

→ 12(x) + 12(10) = 24

→ 12x + 120 = 24

→ 12x = 24 - 120

→ 12x = -96

→ x = -96 ÷ 12

→ [ x = -8 ]

Hence, the value of x is -8.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given;

The new laptop is currently priced at $859

On saturday the store is giving a 25% discount off all laptops

Sales tax on final purchase=8.5%

Now, the final value on saturday be x

x*100/859=25

x=25*859/100

x=214.75

The value will be 859-214.75=644.25

8% of 644.25

x*100/644.25=8

x=8*644.25/100

x=51.54

Final cost= 644.25+51.54

=695.79

Therefore, the final cost after 8 percent sales tax will be $695.79
