is (0,0) a solution to this system? y ≥ x^2-4 y<2x-1

The vertex of the parabola y = x² - 16x + 24 will be at (8, -40). Then the correct option is D.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation is given below.

y = x² - 16x + 24

Convert the equation into vertex form, then we have

y = x² - 16x + 24

y = x² - 2·8·x + 8² - 8² + 24

y = (x - 8)² - 64 + 24

y = (x - 8)² - 40

The vertex of the parabola y = x² - 16x + 24 will be at (8, -40). Then the correct option is D.

The area of a circle with a circumference that equals the perimeter of the square is 9.62 units².

What is circle ?

the side measurements of the square is 2.75 units.

the perimeter of this square, we must multiply 2.75 by 4 because a square has four equal side measurements.

2.75 × 4 = 11

Let's use the formula for finding radius given the circumference.

\(Radius = \frac{circumference}{2\pi }\)

the circumference because our circumference is 11 units.

Radius = \(\frac{11}{2pi }\)

put π = 3.14 * 2

radius =  11 / 2 * 3.14

radius = 11/  6.28 ⇒ 1.75

the area of the circle = \(\pi r^{2}\)

area = 3.14 * (1.75)²  ⇒9.61325

Lastly, we round this number to the nearest hundredth as it is asked of us in the problem.

9.61325 = 9. 62

Therefore, the area of the circle is 9.62 units².

The correct code to swap elements 0 and 1 in the given array {7, 8, 10, 11, 4, 3} would be: int save = array[0];array[0] = array[1];array[1] = save;

The code above uses a temporary variable "save" to store the value of the first element of the array, then assigns the value of the second element to the first element, and finally assigns the value of "save" (which holds the original value of the first element) to the second element.

The other lines of code following this swap code would perform additional operations on the array, but they do not correctly swap the first two elements of the array.

For example, the line array[0] = array[1]; in the given code only assigns the value of the second element to the first element, effectively overwriting the original value of the first element before it can be saved. Similarly, the line array[1] = array[0]; then assigns the overwritten value of the first element to the second element, resulting in no swap at all.

Therefore, the correct code to swap the first two elements of the array is the code I mentioned at the beginning of this answer.

To calculate John's BMI, we need to use the formula BMI = weight (kg) / height (m)^2. When we calculate this, we get a BMI of 36.1.

First, we need to convert John's height and weight to the metric system. His height is 1.75 meters and his weight is 110.5 kilograms.
Next, we can plug those values into the formula: BMI = 110.5 / (1.75)^2.
According to the Centers for Disease Control and Prevention, a BMI of 30 or above is considered obese. Therefore, John falls into the obese category based on his BMI.
It's important to note that BMI is just one measure of health and does not take into account muscle mass or other factors that can affect weight. It's always best to speak with a healthcare professional to determine a healthy weight and lifestyle plan.

Explenation:

Total number of players = p

According to given scenario:

p - 12 = 3/4p

By simplifying

Taking terms with p on left and constants on right

p - 3/4p = 12

By taking LCM for left side to make denominators same

4/4*p -3/4p = 12

(4p -3p)/4 = 12

1p/4 = 12

Multiplying both sides by 4 we get

p = 12 * 4

p = 48

In a multiple regression model, the variance of the error term e is assumed to be the same for all values of the independent variable. Therefore, the correct option is C) the same for all values of the independent variable.

In multiple regression, we use several independent variables to predict the values of the dependent variable. The model estimates the relationship between the independent variables and the dependent variable by calculating the coefficients of the independent variables.

The error term e represents the difference between the predicted value of the dependent variable and the actual value of the dependent variable.

The assumption of constant variance of the error term e is known as homoscedasticity. It means that the variance of the errors is the same for all levels of the independent variables.

This assumption is important because, if the errors have different variances across the levels of the independent variable, the model may not accurately capture the relationship between the independent variables and the dependent variable, leading to biased and unreliable results. so, the correct answer is C).

Answer:

726.65 cubic inches

Step-by-step explanation:

We are going to assume that the head, middle and bottom are spheres.

The formula to get the volume of a sphere is

\(V= \frac{4}{3}\pi r^{2}\) where r is the radius of the sphere.

Now, let's proceed to apply this formula to the 3 spheres of the snowman:

The head is 12 inches wide (diameter), thus, the radius would be 6 inches:

\(V= \frac{4}{3}\pi r^{2}\\V= \frac{4}{3}\pi 6^{2}\\V= \frac{4}{3}\pi 36\\V=\frac{144\pi }{3} \\V=38\pi\) cubic inches

The middle is 16 inches wide (diameter), thus, the radius would be 8 inches.

\(V= \frac{4}{3}\pi r^{2}\\V= \frac{4}{3}\pi 8^{2}\\V= \frac{4}{3}\pi 64\\V=\frac{256\pi }{3} \\V=85.3\pi\)  cubic inches

The bottom is 18 inches wide (diameter), thus the radius would be 9 inches.

\(V= \frac{4}{3}\pi r^{2}\\V= \frac{4}{3}\pi 9^{2}\\V= \frac{4}{3}\pi 81\\V=\frac{324\pi }{3} \\V=108\pi\) cubic inches.

Now, to get the total volume of the snowman we're going to sum up the volume of all three spheres:

Total volume = \(38\pi +85.3\pi +108\pi =231.3\pi\) cubic inches.

If we take pi = 3.1416,

Total volume = \(231.3(3.1416)=726.65\) cubic inches.

The probability of randomly selecting an orange tile and not replacing it, then randomly selecting a blue tile is 1/10 or 0.1. In order to find the probability of selecting an orange tile and then a blue tile without replacement, we need to use the formula for conditional probability.

This formula states that the probability of an event A given that event B has occurred is equal to the probability of both A and B occurring divided by the probability of B occurring.We can represent the events as follows:A = selecting an orange tileB = selecting a blue tile given that an orange tile has already been selected without replacement.

We know that there are 10 orange tiles and a total of 6 + 9 + 10 = 25 tiles. Therefore, the probability of selecting an orange tile on the first draw is:P(A) = 10/25 = 2/5.

After an orange tile has been selected, there are 24 tiles remaining, of which 6 are blue. Therefore, the probability of selecting a blue tile given that an orange tile has already been selected is:P(B|A) = 6/24 = 1/4.Putting it all together, we can use the formula for conditional probability to find the probability of selecting an orange tile and then a blue tile without replacement:

P(A and B) = P(A) * P(B|A) = (2/5) * (1/4) = 1/10.Therefore, the probability of randomly selecting an orange tile and not replacing it, then randomly selecting a blue tile is 1/10 or 0.1.

Answer:  3∛3

Step-by-step explanation:

81^(1/3) = ∛(81) = ∛(27 × 3) = 3∛3

Answer:If p and q vary inversely, it means that their product remains constant. So we can set up the equation:

p * q = k

where k is the constant of variation.

Given that p is 29 when q is 25, we can substitute these values into the equation:

29 * 25 = k

725 = k

Now, let's determine the value of q when p is equal to 5:

p * q = k

5 * q = 725

Dividing both sides of the equation by 5:

q = 725 / 5

q = 145

Therefore, when p is equal to 5, q is equal to 145.

Step-by-step explanation:

Answer:p1q1=p2q2

q1=25,p1=29;

p2=5,q2=?;

q2=p1q1/p2;

The mountain range would cause allopatric speciation, resulting in genetic divergence and the formation of two distinct populations of sheep adapted to their respective environments.



The mountain range separating the two populations of sheep would likely lead to allopatric speciation. Over time, the isolated populations would experience different selective pressures, leading to genetic divergence. Mutations, genetic drift, and natural selection would contribute to the accumulation of genetic differences.



The distinct environments on either side of the mountain range may drive adaptations specific to each population. As reproductive isolation develops, the two groups may become distinct species.

The mountain range acts as a geographical barrier, promoting allopatric speciation and resulting in two separate and genetically unique populations of sheep.

If two methods agree perfectly in a method comparison study, the slope equals 1.0 and the y-intercept equals 0.0. Therefore, option (b) is the correct answer.

In a method comparison study, the goal is to compare the agreement between two different measurement methods or instruments. The relationship between the measurements obtained from the two methods can be described by a linear equation of the form y = mx + b, where y represents the measurements from one method, x represents the measurements from the other method, m represents the slope, and b represents the y-intercept.

When the two methods agree perfectly, it means that there is a one-to-one relationship between the measurements obtained from each method. In other words, for every x value, the corresponding y value is the same. This indicates that the slope of the line connecting the measurements is 1.0, reflecting a direct proportional relationship.

Additionally, when the two methods agree perfectly, there is no systematic difference or offset between the measurements. This means that the line connecting the measurements intersects the y-axis at 0.0, indicating that the y-intercept is 0.0.

Therefore, in a perfect agreement scenario, the slope equals 1.0 and the y-intercept equals 0.0, which corresponds to option (b).

To calculate the balance in the savings account after 17 months with a monthly interest rate of 3.3%, we can use the formula for compound interest:

\(\[ A = P \left(1 + \frac{r}{n}\right)^{nt} \]\)

Where:

A is the final amount (balance) in the account,

P is the principal amount (initial investment),

r is the interest rate per period (in decimal form),

n is the number of compounding periods per year,

and t is the number of years.

In this case, the principal amount P is $300, the interest rate r is 3.3% (or 0.033 in decimal form), the compounding is done monthly (so n = 12), and the time period t is 17 months divided by 12 to convert it to years (approximately 1.4167 years).

The value of the integral is 1710. To evaluate the integral S1 0 (1+1/2u⁴ - 2/5u⁹)du, we need to integrate each term separately.

∫1du = u + C, where C is the constant of integration.

To integrate 1/2u⁴, we can use the power rule of integration:

∫1/2u⁴ du = (1/2) ∫u⁴ du = (1/2) * u⁵/5 + C = u⁵/10 + C

To integrate -2/5u⁹, we can also use the power rule of integration:

∫(-2/5)u⁹ du = (-2/5) ∫u⁹ du = (-2/5) * u¹⁰/10 + C = -u¹⁰/25 + C

Putting everything together, we have:

∫(1+1/2u⁴ - 2/5u⁹)du = ∫1du + ∫1/2u⁴ du - ∫2/5u⁹ du

= u + u⁵/10 - (-u¹⁰/25) + C

= u + u⁵/10 + u¹⁰/25 + C

Now, we can evaluate the definite integral by plugging in the limits of integration:

S1 0 (1+1/2u⁴ - 2/5u⁹)du = [u + u⁵/10 + u¹⁰/25]₁⁰

= (10 + 10⁵/10 + 10¹⁰/25) - (0 + 0⁵/10 + 0¹⁰/25)

= 10 + 1000 + 400000/25

= 10 + 1000 + 16000

= 1710

Therefore, the value of the integral is 1710.
