Answer:

D. x² + y² = 4²

Step-by-step explanation:

The general equation of a circle is given in the attached  graphic.

In this case, we can see that the center of the circle is at the origin i.e (0,0) and that the radius is 4 units.

the values for h, k and r in the general equation are as follows:

h = 0, k=0, r = 4

putting this into the general equation:

(x-h)² + (y-k)² = r²

(x-0)² + (y-0)² = 4²

x² + y² = 4²

The equation of the circle centered at the origin with a radius of 4 is:

x² + y² = 4².

Option D is the correct answer.

We have,

The equation of a circle centered at the origin (0, 0) with a radius of 4 can be written in the form:

[tex]x^2 + y^2 = r^2[/tex]

where (x, y) represents any point on the circle and r is the radius.

Substituting the given radius of 4 into the equation, we have:

x² + y² = 4²

x² + y² = 16

Therefore,

The equation of the circle centered at the origin with a radius of 4 is:

x² + y² = 4².

Answer: 32÷4+3=11

Step-by-step explanation:

24÷3=8

Answer:

80 + 18i

Step-by-step explanation:

i² = -1

x = i + 9

x² = (i + 9)²

Applying; (a + b)² = a² + 2ab + b² concept,

x² = i² + 18i + 81

We know that i² = -1

So x² = -1 + 18i + 81

x² = 81 - 1 + 18i = 80 + 18i

The square of the complex number x = i + 9 is computed by squaring each term and combining the results, giving us 80 + 18i as the final squared value.

To square the complex number x = i + 9, we use the formula for squaring a binomial:

Square the first term: i² = -1.

Square the second term: 9² = 81.

Multiply the first term by the second term and by 2 for the middle term: 2 times i times 9 = 18i.

Sum all the terms together -1 + 81 + 18i = 80 + 18i.

So, the result of squaring x is 80 + 18i.

Step-by-step explanation: The probability of choosing a girl is the number of girls over the total number of students. Since there are 16 girls and 16+18 students, 16/34=8/17. Hope this helps! (Could I please have brainliest?)

The probability of the teacher choosing a girl to answer the question is 8/17. The correct option is C.

To calculate the probability of the teacher choosing a girl to answer the question, we need to determine the ratio of the number of girls to the total number of students.

In the given class, there are 16 girls and 18 boys, making a total of 16 + 18 = 34 students.

The probability of selecting a girl is the number of favourable outcomes (girls) divided by the total number of possible outcomes (students).

Therefore, the probability is 16 (number of girls) / 34 (total number of students).

Simplifying this fraction, we have 8/17.

Hence, the correct option is C. 8/17, which represents the probability of the teacher choosing a girl to answer the question.

Hope I helped :)

Answer:

-7

Step-by-step explanation:

The rule for subtraction, in this case it is -5-3, you change the subtraction sign to addition and use the opposite of the second number, making it -5+(-3) which is -8. Then, you add 1 to -8, and the rule for this specific expression is to take the absolute value of both -8 and 1, then subtract the two, making the expression as of now 8-1. Subtract them, and get 7, but you take the sign of whichever number had the greatest absolute value, which was -8, so now the answer is -7. That's how you get your answer

-5-3+1= -5+(-3)+1

-8+1= |-8|-|1|

8-1= -7 (because you take the sign with the greatest absolute value, which is -8.)

Step-by-step explanation:

We have to choose the function whose graph is given.

A.[tex]y=sinx+2[/tex]

Substitute x=0 then

[tex]y=0+2=2[/tex]

Therefore, y- intercept is at y=2.

Substitute [tex]x=\frac{\pi}{2}[/tex]

[tex]y=sin\frac{\pi}{2}+2=1+2=3[/tex] because ([tex]\sin\frac{\pi}{2}=1[/tex])

Substitute  [tex]x=-\frac{\pi}{2}[/tex]

Then we get

[tex]y=sin(-\frac{\pi}{2})+2=-sin\frac{\pi}{2}+2=-1+2=1[/tex]

[tex] sin (-x)=-sinx[/tex]

Therefore, given graph is [tex]y=sinx +2[/tex]

B.[tex]y=-sinx+2[/tex]

When Substitute  [tex]x=-\frac{pi}{2}[/tex]

Then, [tex]y=-sin(-\frac{\pi}{2})+2=sin\frac{pi}{2}+2=1+2=3[/tex]

But  in graph at [tex]x=-\frac{pi}{2}[/tex] , y=-1

So,It is not true.

C.[tex]y=cosx+2[/tex]

When x=0

then we get [tex]y=cos0+2=1+2=3[/tex] (cos 0=1)

But in graph  y - intercept at y=2

So, it is false.

D.[tex]y=-cosx+2[/tex]

Substitute x=0

Then, we get

[tex]y=-cos 0+2=-1+2=1[/tex]

So, it is false.

Answer: [tex]y=sinx +2[/tex]

Answer: Hello there!

we know that on Tuesday, Jennie finished her sprint 0.305 seconds faster than on Monday, and we want to model this with math.

If we define x as the time in which she finished ger sprint on Monday, we can write the time for Tuesday as x - 0.305s

this is because she finished her sprint 0.305 seconds "faster", this means that she finished it in less time, so you need to subtract this number to the previous time.

Then the meaning of 0.305 is the amount of time that you need to subtract from the previous time, in order to get the actual time that she needs to finish the sprint.

Answer:

5.5! Now, you need to know why. The total cost was $490, there is a fee of $50, so subtract the fee from the total cost and you should  then divide that by $80 because thats how much it is an hour.

The actual equation should be 80x + 50 = 490, not 80x - 50 = 490. By solving it, we find out that the job took 5.5 hours to complete.

The given equation in the problem is incorrect. It should be 80x + 50 = 490, where x represents the number of hours the plumber worked. This equation accounts for the hourly charge (80x) and the upfront flat fee ($50). To solve for x, we begin by isolating it on one side of the equation. We subtract 50 from both sides to get 80x = 440. Then we divide both sides by 80, resulting in x = 5.5. Therefore, the plumber worked for 5.5 hours on this particular job.

Final answer:

After arranging the data for each company and calculating the first and third quartiles, we found that the interquartile range for Company A's students (IQR = 2) is 1 more than the interquartile range for Company B's students (IQR = 1).

Explanation:

The interquartile range (IQR) is a measure of the middle spread of a data set, calculated as the difference between the third quartile (Q3) and the first quartile (Q1). To find the interquartile range for each group of students, we will first need to arrange each company's data in ascending order and then find the values of Q1 and Q3 for each group.

For Company A, the data in ascending order is: 1, 1, 1, 2, 2, 3, 3, 4, 5. Q1 is the median of the first half (1), and Q3 is the median of the second half (3). Thus, IQR is 3 - 1 = 2.

For Company B, the data in ascending order is: 1, 1, 2, 2, 2, 2, 2, 3, 3. Q1 is the median of the first half (1.5), and Q3 is the median of the second half (2.5). So, IQR is 2.5 - 1.5 = 1.

Comparing the IQRs, we find that the interquartile range for Company A's students is 1 more than the interquartile range for Company B's students.
