3) A diameter divides a circle into two congruent arcs. What is the measure in degrees for each arc?
A. 60°
B. 45°
C. 180°
D. 90°
Answer:
C. 180°
Step-by-step explanation:
The degree measure of the arc of a full circle is 360°
A diameter divides a circle into two parts of equal size, so the degree measure of each part is half of the degree measure of a full circle.
360°/2 = 180°

Select each graph that shows a function and it’s inverse
Answer:
First option
Explanation:
The inverse of a graph is its reflection on the line y = x.
This means that it is the graph that you get by reflecting the original graph on a line with the equation y = x.
In the picture below, we can see a function (red graph), its inverse (blue graph) and the line (green) that the two graphs are reflected on.
From the picture below, we can see that the shapes of the graph of a function and its inverse is similar and correspond to the shape given as the first option in the question. Therefore, the first option is the answer.

What is the length of focal chord of the equation y^2 + 6y - 2x + 13 = 0?
Answer:
2 units
Step-by-step explanation:
The given equation graphs as a parabola that opens to the right. It can be written in the form ...
(4p)x = ay² +by +c
Interpreting the equationWhen the equation is written in the form ...
(4p)x = ay² +by +c
The value of p is the focus-to-vertex distance. The length of the latus rectum (focal chord) is 4 times the value of p, so is the coefficient of x in the equation.
ApplicationRewriting the given equation to the form shown above, we have ...
2x = y² +6y +13
That is, the value of 4p, the coefficient of x, is 2. The length of the focal chord is 2 units.

Let V(x)=−x2+2x−4 and W(x)=−x3+2x2+x+5. Find V(x)⋅W(x)
Answer:
B
Step-by-step explanation:
I assume this should look like
V(x) = -x² + 2x - 4
W(x) = -x³ + 2x² + x + 5
when doing arithmetic operations with whole functions, we simply do these operations with the whole expressions :
V(x) × W(x) =
(-x² + 2x - 4) × (-x³ + 2x² + x + 5) =
= x⁵ - 2x⁴ - x³ - 5x² - 2x⁴ + 4x³ + 2x² + 10x + 4x³ - 8x² - 4x - 20 =

If m < ACD = 100 , then m < ACE = ?
If m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.
Supplementary angles are the angles whose sum is equal to 180°. The angles formed when one straight line intersects the other, on the point of intersection on the same side of any line are always supplementary.
In the given question, AB and DE are two straight lines intersecting at point C. ∠ACD and ∠ACE lie on the same side of the line DE, thus they are supplementary angles.
Therefore, m ∠ACD + m ∠ACE = 180°.
But we know that m ∠ACD = 100°. So,
m ∠ACD + m ∠ACE = 180°,
or, 100° + m ∠ACE = 180°,
or, m ∠ACE = 180° - 100° = 80°.
Therefore, if m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.

What are the x-intercepts and the y-intercepts of the graph of 12x−3y=36
Answer:
Step-by-step explanation:
12x −3y=36 ⇔ 3y = 12x - 36
y = 4x - 12
y = 0 ⇔ 4x - 12 = 0 ⇔ 4x = 12 ⇔ x = 12/4 = 3
So (0 ; - 12) and (3 ; 0)
Answer:
x-intercept=3, y-intercept=-12
Step-by-step explanation:
at x-intercept y=0 such that:
12x-3(0)=36

The table shows three values of x and their corresponding values of f (x) for a linear function f, such that f (r) = 0 and f (0) = s, where r and s are constants. What is the value of rs?
Using a linear function, it is found that the product rs is rs = 81.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, when x changes by 68(from -64 to 68), y changes by -16(from 12 to -4), hence the slope is given by:
m = -16/64 = -0.25.
Hence:
y = -0.25x + b.
When x = 34, y = -4, hence this is used to find b.
-4 = -0.25(34) + b
b = 4.5.
Hence the function is:
y = -0.25x + 4.5.
f(r) = 0, hence:
-0.25x + 4.5 = 0
x = 4.5/0.25
x = 18
r = 18.
f (0) = s, hence s = 4.5.
Then the value of the product is:
rs = 18 x 4.5 = 81.
