Step-by-step explanation:
The Tangent-Secant Exterior Angle Measure Theorem states that if a tangent and a secant or two tangents/secants intersect outside of a circle, then the measure of the angle formed by them is half of the difference of the measures of its intercepted arcs. Basically, what that means here is that [tex]x[/tex] equals half of the difference of [tex]30\textdegree[/tex] and the measure of the unlabeled arc.
First, we need to find the measure of the unlabeled arc, since we can't find [tex]x[/tex] without it. We know that the measure of the full arc formed by the circle is [tex]360\textdegree[/tex], so the measure of the unlabeled arc must be [tex]360-30-100-100=130\textdegree[/tex] by the Arc Addition Postulate.
Now, we can find [tex]x[/tex]. Using all of the information known, we can solve for [tex]x[/tex] like this:
[tex]\\x=\frac{1}{2} (130\textdegree-30\textdegree)\\=\frac{1}{2} (100\textdegree)\\=50\textdegree[/tex]
Hope this helps!

AKS 19 -- Dan is driving with an average speed of s. He is driving a total distance of d. What formula represents the total time of his trip? Question 2 options: t=ds t = d s t=ds t=d-s t=sd
Answers
Answer:
[tex]t=\dfrac{d}{s}[/tex]
Step-by-step explanation:
Dan is driving with an average speed of s. He is driving a total distance of d.
The average speed of an object is given by :
Average speed = total distance/total time
Let b the time of his trip
So,
[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]
So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].

The center of a circle is (0, -8). The radius is 9. What is the equation of the circle? Select all that apply.
A. x2 + (y + 8)2 = 3
B. x2 + (y + 8)2 = 9
C. x2 + (y + 8)2 = 81
D. x2 + y2 + 16y = 17
E. x2 + y2 + 16y = -55
Answers
Answer:
x² + (y + 8)² = 81
Step-by-step explanation:
Centre (h,k) = (0,-8)
radius (r) = 9
(x - h)² + (y - k)² = r²
(x - 0)² + (y + 8)² = 9²
x² + (y + 8)² = 81

Given:
Midpoint = (2,-14)
One endpoint = (4,-13)
To find:
The another endpoint.
Solution:
Let (a,b) be the another endpoint.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using midpoint formula, we get
[tex](2,-14)=\left(\dfrac{a+4}{2},\dfrac{b+(-13)}{2}\right)[/tex]
[tex](2,-14)=\left(\dfrac{a+4}{2},\dfrac{b-13}{2}\right)[/tex]
On comparing both sides, we get
[tex]2=\dfrac{a+4}{2}[/tex]
[tex]4=a+4[/tex]
[tex]4-4=a[/tex]
[tex]0=a[/tex]
And,
[tex]-14=\dfrac{b-13}{2}[/tex]
[tex]-28=b-13[/tex]
[tex]-28+13=b[/tex]
[tex]-15=b[/tex]
Therefore, the another endpoint is (0,-15).
solve algebraically
1. y = x^2+ 3x - 5
y = x + 3
2. y = x^2- 4x + 6
y = x + 2
3. y = x^2- 10x + 14
y = 7x - 16
4. y = x^2-24
y = x - 12
5. y = x^2- 8x + 28
y = 4x + 8

Given the function h(x)=-x^2+4x+12, determine the average rate of change of the function over the interval −2≤x≤4.
Answers
Answer:
2
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is
[tex]\frac{f(b) - f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 2, 4 ] , then
f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12
f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0
Then
average rate of change = [tex]\frac{12-0}{4-(-2)}[/tex] = [tex]\frac{12}{6}[/tex] = 2

There is an ordered pair that is the solution of the system of equations shown. The value of one of the variables in the solution of the system can be obtained by using which of the following substitutions?
A) 2 (2c - 1) + 3c = 5, because a = 2c - 1.
B) 2 (1 - 2c) + 3c = 5, because a = 1 - 2c.
C) 2a + 3 (a - 1) = 5, because c = a - 1.
D) 2a +3(1 - a) = 5, because c = 1-a
Answers
Answer:
A
Step-by-step explanation:
The required system that can be obtained by substituting is
2 (1 - 2c) + 3c = 5, because a = 1 - 2c.
Given the system of equation;
2a + 3c = 5
a +2c=1
This system can be solved using the substitution method.
From equation 2:
a = 1 - 2c ...................... 3Substitute equation 3 into 1 will give:
2a + 3c = 52 (1- 2c) + 3c = 5Hence the required system that can be obtained by substituting is
2 (1 - 2c) + 3c = 5, because a = 1 - 2c.

The letters in the word JANUARY were put in a bag and drawn randomly. What is the probability of picking an a?
Answers
Answer: 2/7
Step-by-step explanation:
There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"
2/7
there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.
