Answer:

(x + 2)² + (y - 5)² = 7²

Step-by-step explanation:

Incomplete question.  I believe you meant, "write the equation of the circle with center at (-2, 5) and radius 7.

That would be:

(x + 2)² + (y - 5)² = 7²

The equation of the circle with center (-2,5) and radius 7 is (x+2)² + (y-5)² = 49.

The question is asking for the equation of a circle with center at (-2,5) and radius 7. The general equation for a circle is (x-h)² + (y-k)² = r², with (h,k) as the center and r as the radius. In this case, h = -2, k = 5, and r = 7, so substituting these into the equation gives us the solution:

(x-(-2))² + (y-5)² = 7², which simplifies to (x+2)² + (y-5)² = 49.

Answer:

x = 56.7°

Step-by-step explanation:

Sin (x) = Oppo. / Hypo.

Sin (x) = 66/79

Sin (x) = 0.8354

     x = 56.7°

Answer:

x ≈ 56.7

Step-by-step explanation:

In the right triangle with hypotenuse 79 use the sine ratio to find x

sinx° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{66}{79}[/tex], hence

x = [tex]sin^{-1}[/tex] ([tex]\frac{66}{79}[/tex] ) ≈ 56.7

Answer:

The value of P( A and B ) is 0.08.

Step-by-step explanation:

When two events are independent then the probability of both occurring is equal to the product of probabilities of both events individually,

That is, If X and Y are independent events,

Then, P(X∩Y) = P(X) × P(Y),

or P(X and Y) = P(X) × P(Y),

Here, P(A) = 0.40 and P(B) = 0.20,

Hence, P(A∩B) = P(A) × P(B)

= 0.40 × 0.20

= 0.08

The value of [tex]\( P(A \text{ and } B) \)[/tex] is 0.08. So option(a) is correct.

To determine[tex]\( P(A \text{ and } B) \)[/tex] for two independent events ( A ) and ( B ) with given probabilities ( P(A) = 0.40 ) and ( P(B) = 0.20 ), follow these steps:

Step 1: Understand the Concept of Independence

For independent events, the probability of both events occurring together (the intersection of A and B, denoted as [tex]\( P(A \cap B) \))[/tex] is the product of their individual probabilities.

Step 2: Apply the Independent Event Formula

Since (A ) and (B ) are self-contained,

[tex]P(A) \times P(B) = P(A \cap B)[/tex]

Step 3: Substitute the Given Probabilities

Insert the given probabilities [tex]\( P(A) = 0.40 \)[/tex] and [tex]\( P(B) = 0.20 \)[/tex] into the formula:

[tex]\[ P(A \cap B) = 0.40 \times 0.20 \][/tex]

Step 4: Perform the Multiplication

Calculate the product of 0.40 and 0.20:

[tex]\[ P(A \cap B) = 0.40 \times 0.20 = 0.08 \][/tex]

Step 5: Interpret the Result

The probability that both events ( A ) and ( B ) occur is 0.08.

Therefore, the correct answer is (a) 0.08.

Complete Question:

A and B are independent events. P(A)=0.40 and P(B)=0.20 . What is P(A and B) ?

A. 0.08

Hello There!

First, let me just explain briefly what is an independent variable and a dependent variable.

An independent variable is the variable that changes during an experiment to see if it has an effect on another variable.

A dependent variable is what is being measured in the experiment. It’s also known as outcome or effect.

In this case, the dependent variable is the number of liters of water your drink because that’s what your measuring.

The independent variable is the number of times you drink all the water in your bottle because that changes during the experiment.

Answer: -0.52

Step-by-step explanation:

From the given scatter plot, it can be seen that there is a moderate negative correlation between the variables as variable X increases variable Y decreases.

The answer is:

The average speed for the total trip is 753.19 mph.

To calculate the average speed for the total trip, we need to calculate the time of travel for both distances according to their speeds.

So, calculating we have:

- First distance and speed: 3334 miles at 760 mph

Let's use the following formula:

[tex]distance=speed*time\\\\time=\frac{distance}{speed}[/tex]

Then, substituting we have:

[tex]time=\frac{3334miles}{760mph=4.39hours}[/tex]

Therefore, we have that the first distance was covered in 4.39 hours.

- Second distance and speed: 2244.7 miles at 740mph

Let's use the following formula:

[tex]distance=speed*time\\\\time=\frac{distance}{speed}[/tex]

Then, substituting we have:

[tex]time=\frac{2244.7miles}{740mph=3.03hours}[/tex]

Therefore, we have that the second distance was covered in 3.03 hours.

Now, calculating the average speed, we have:

[tex]AverageSpeed=\frac{distance_{1}+distance_{2}}{t_{1}+t_{2}}[/tex]

Substuting we have:

[tex]AverageSpeed=\frac{3344miles+2244.7miles}{4.39hours+3.03hours}[/tex]

[tex]AverageSpeed=\frac{5588.7miles}{7.42hours}=753.19mph[/tex]

Hence, we have that the average speed for the total trip is 753.19 mph.

Answer:

x = -2 and y = 2

Step-by-step explanation:

We have the following system of linear equations;

y=x+4

y=-2x-2

To solve the above system, we shall be equating the right hand sides of the two equations since we have y's on the left hand side of both equations;

x + 4 = -2x - 2

add 2x on both sides of the equation;

x + 4 + 2x = -2x - 2 + 2x

3x + 4 = -2

subtract 4 on both sides of the equation;

3x + 4 - 4 = -2 - 4

3x = -6

x = -2

We can use the first equation y=x+4 to determine the value of y;

y = -2 + 4

y = 2

The solution to the system of linear equations is thus;

x = -2 and y = 2

Answer:

25 gallons

Step-by-step explanation:

Given:

total no. of gallons= 50

Percentage of sulfuric acid= 50%

Number of gallons of sulfuric acid= total no. of gallons x Percentage of sulfuric acid

Putting values in above equation:

Number of gallons of sulfuric acid= 50 x 50/100

                                                        = 50 x 1/2

                                                        = 25 !

To find the number of gallons of sulfuric acid in a 50-gallon solution with a 50% concentration, multiply the volume of the solution by the concentration.

To find the number of gallons of sulfuric acid in a 50-gallon solution with a 50% concentration, you can use a simple calculation. The percent concentration represents the fraction of sulfuric acid in the solution, so you can calculate the amount of sulfuric acid by multiplying the volume of the solution by the concentration:

Volume of sulfuric acid = Volume of solution * Percent concentration

Volume of sulfuric acid = 50 gallons * 0.50 = 25 gallons

Therefore, there are 25 gallons of sulfuric acid in the 50-gallon solution.

It's necessary to do the same thing to both sides of an equation to maintain balance and allow valid operations. This basic principle is crucial for solving and simplifying equations in mathematics.

In mathematics, it is necessary to do the same thing to both sides of an equation to perform valid operations. An equation represents a balance; what is done to one side must also be done to the other to maintain this balance. For instance, if you add, subtract, multiply, or divide a value from/to one side of an equation, you have to do the same to the other side. This principle is essential for solving and simplifying equations. For example, in the equation 5x + 3 = 18, to solve for x, you would subtract 3 from both sides, establishing the new equation 5x = 15, maintaining the balance.

OPTION A

Step-by-step explanation:

The exponential growth functions has the following form:

[tex]y=a(b)^x[/tex]

Where "a" is the principal coefficient and  "b" is the base greater than 1.

To know which of the functions shown has exponential growth, identify which one has a base greater than 1.

[tex]\frac{4}{3}=1.33>1[/tex]

Therefore, the exponential growth function is the function shown in the option A.

The answer is:

The correct answer is:

A) [tex]y=(\frac{4}{3})^{x}[/tex]

To identify which of the given functions is an exponential growth function, we need to remember the form of the exponenial growth or decay functions.

We can define the exponential growth or decay function by the following way:

[tex]P(x)=y=StartValue*(rate)^{x}[/tex]

Where,

P(x) or y, is the function

Start value is the starting amount or value

Rate, is the growth or decay rate

x, is the variable (time)

Now, we can identify if the function is a exponential growth or decay function by the following way:

If [tex]rate>1[/tex] the function is an exponential growth function.

If [tex]rate<1[/tex] the function is an exponential decay function.

Now, we are given the function first function, A)

[tex]y=(\frac{4}{3})^{x}[/tex]

Where,

[tex]rate=\frac{4}{3}=1.33[/tex]

and we have that:

[tex]rate>1\\1.33>1[/tex]

So, the function is an exponential growth function.

Hence, the correct answer is:

A) [tex]y=(\frac{4}{3})^{x}[/tex]

Where [tex]A_b[/tex] is the base area and h is the height.

So, if we call [tex]V_1,\ V_2[/tex] the volumes with the original and the doubled area, we have

[tex]V_1 = A_bh,\quad V_2 = A_b(2h)[/tex]

Since the height was doubled. We deduce that
