What is a cyclic Quadrilateral?

A cyclic quadrilateral is a quadrilateral circumscribed by a circle in which all the vertices of the quadrilateral touch the circle.

Analysis:

Join line Qx and Sx together.

2∠QRS = reflex ∠QxS ( twice angle at the circumference is that at center)

2∠STQ = ∠QxS( twice angle at circumference is that at the center)

Also ∠QXS + reflex ∠QXS = 360(angle at a point)

2∠QRS + 2∠STQ = 360

2(∠QRS + ∠STQ) = 360

∠QRS + ∠STQ = 180°

In conclusion, ∠QRS + ∠STQ = 180°

What’s the domain and range

Answers

Step-by-step explanation:

the domain is the interval or set of all valid x-values for the function.

and the range is the interval or set of all valid y-values (functional result values) for the function.

so, we can see here that the function would create results for all x in (- infinity, + infinity). that is the domain.

now, what result values (y-values) are possible ?

we see, that the smallest functional value is y = -2.

and from there all y-values up to +infinity are possible.

so, the range is [-2, +infinity).

please consider the chosen brackets. the "[" means the value is included in the function, a "(" means that that particular interval end value is excluded. anything bigger or smaller might be valid but not this one value.

and infinity is not a value. hence they are not included in such intervals.

Integration is defined as the adding up all the small units to find the whole unit.

It is given in the question that the line y=3x is making a region in a plane from the limits x= to x=4.

So by integrating the function we will get the area.

Find the sum.
-85+ (-81) + (-77)+...+31 + 35

Answers

Answer:

The sum of all the terms is -775.

Step-by-step explanation:

This appears to be an arithmetic sequence, with a common difference of 4.

The problem is, we don't know how many terms there are!

To find this, use the following formula:

last number = first number + (n - 1) * difference

In this case:

35 = -85 + (n - 1) * 4

35 = -85 + 4n - 4

4n = 124

n = 31

This means there are 31 terms in this sequence.

Now, for the sum. Use the following formula:

n(first number + last number), take this product and divide it by 2.

In this case:

31(-85 + 35) = -1550 / 2 = -775

Several students made comments about this image.

A triangle has angles B, C, D. The exterior angle to angle B is A.

Which comment is true?
“If I know the measures of A and B, I can subtract those measures from 180 to find the measures of the other two angles.”
“If I know the measure of C, I can find the measure of angle A because they are the same.”
“If I know the measures of angles C and B, I can find the measures of A and D.”
“If I know the measure of angle A, I can find the measure of angle D by subtracting from 180

Answers

Answer:

The third comment is the true one: "If I know the measures of angles C and B, I can find the measures of A and D."

This is because you can use the angle B to find angle A by subtracting it from 180, and you can find angle D by adding together C and B and subtracting that from 180.

The circumference of a circle is 24π cm. What is the area, in square centimeters? Express your answer in terms of \piπ.

Answers

Given the value of the circumference of the circle, its area in terms of constant pi is 144πcm².

What is a circle?

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The area and circumference  of a circle is expressed mathematically as;

A = πr²C = 2πr

Where A is area, C is circumference, r is radius and π is constant pi.

Given the data in the question;

Circumference of the circle C = 24π cmArea A = ?

First, we determine the radius of the circle.

24π cm = 2πr

r = 24π cm / 2π

r = 12cm

Now, we find the area.

A = πr²

A = π × (12cm)²

A = π × 144cm²

A = 144πcm²

Therefore, given the value of the circumference of the circle, its area in terms of constant pi is 144πcm².

uhhh what is this this looks very hard

Answers

Answer:

B. x ≤ 5

Step-by-step explanation:

This is an inequality problem. It can be solved by examining the arrow and the point it closes on. If the arrow is going left, then all values of x are going to be less than the point it closes on. If the arrow is going right, then all values of x are going to be greater than the point it closes on.
If the circle on the point the arrow is closed/shaded in, then that value will be included in the values of x, giving the inequality either a ≤ or ≥ sign depending on which way the arrow is pointing. If the circle on the point the arrow is open, then that value will not be included in the values of x. The sign will be either < or >.

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

For this problem, the arrow is going to the left of 5, which means all values of x are going to be less than 5. Because the circle is closed, that means that number 5 is included, or x can be equal to 5. If the circle was open, it wouldn't be included. So, the inequality is x ≤ 5.
