Answer: [tex]\angle G=23\°[/tex]
Step-by-step explanation:
Remember that an inscribed angle is defined as an angle formed by two chords and whose vertex lies on the circle.
By definition, the measure of an inscribed angle is:
[tex]Inscribed\ Angle=\frac{Intercepted\ Arc}{2}[/tex]
You know that:
[tex]Intercepted\ Arc=AD = (6x -80)\\\\Inscribed\ Angle=\angle G=(x + 2)[/tex]
Then, you need to substitute values and solve for "x":
[tex](x+2)=\frac{(6x -80)}{2}\\\\2(x+2)=6x-80\\\\2x+4=6x-80\\\\4+80=6x-2x\\\\84=4x\\\\x=\frac{84}{4}\\\\x=21[/tex]
Substituting the value of "x" into [tex]\angle G=(x + 2)\°[/tex] you get:
[tex]\angle G=(21 + 2)\°=23\°[/tex]
Answer:
The measure of <G = 23°
Step-by-step explanation:
From the figure we can write,
The measure of <G is half the the measure of arc AD
To find the value of x
We have AD = (6x - 80)° and <G = (x + 2)°
6x - 80 = 2(x + 2)
6x - 80 = 2x + 4
6x - 2x = 4 + 80
4x = 84
x = 84/4 = 21
To find the measure of <g
m<G = x + 2
= 21 + 2 = 23°
Therefore the measure of <G = 23°

the center of a circle is A(-3, 3) and B(1, 6) is on the circle. Find the area in terms of pi.
Answer:
[tex]\large\boxed{A=25\pi}[/tex]
Step-by-step explanation:
The formula of an area of a circle:
[tex]A=\pi r^2[/tex]
r - radius
We have the center A(-3, 3) and the point on the circle B(1, 6).
The radius is equal to the distance between the center and the any point on the circle.
The formula of a distance between two points:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute:
[tex]r=\sqrt{(1-(-3))^2+(6-3)^2}=\sqrt{4^2+3^2}=\sqrt{16+9}=\sqrt{25}=5[/tex]
[tex]A=\pi(5^2)=25\pi[/tex]
The area of the circle centered at A(-3, 3) and passing through B(1, 6) is 25π square units.
Explanation:The subject of this problem is geometry, specifically about the area of a circle.To find the area of a circle, we need to know the radius. Since B is on the circle, AB is the radius. The area (A) of a circle is found using the formula A = πr², where r represents the radius of the circle. Here, the radius of the circle can be determined by finding the distance between the center A(-3, 3) and a point on the circle B(1, 6).
The formula for distance between two points in a plane is √[(x₂ - x₁)² + (y₂ - y₁)²]. Substituting values, we get r = √[(1 - -3)² + (6 - 3)²] = √[(4)² + (3)²] = √[16 + 9] = √25 = 5. Therefore, the radius is 5.
Substitute r = 5 in the area formula: A = π * (5)² = 25π square units.

The isosceles trapezoid is part of an isosceles triangle with a 42 degree vertex
What is the measure of an obtuse base angle of the trapezoid? The diagram is not drawn to scale
PLEASE HELP ME SOLVE Questions 5. And 6. !!! Please
Answer:
the measure of the obtuse base angle of the trepezoid is 111.
Step-by-step explanation:
An isosceles triangle has one vertex angle and two congruent base angles. Also, we know that the sum of all angles in a triangle must equal 180 degrees. So we can say that:
Vertex Angle + Base Angle + Base Angle = 180.
Vertex Angle + 2 x (Base Angle) = 180.
2 x (Base Angle) = 180 - Vertex Angle
2 x (Base Angle) = 180 - 42
2 x (Base Angle) = 138
Base Angle = 69
Also, we know that angles on one side of a straight line always add to 180 degrees.
So we can say that:
Base Angle + ? = 180
? = 180 - Base Angle
? = 180 - 69
? = 111
So, the measure of the obtuse base angle of the trepezoid is 111.

A sphere has a radius of 3m. Calculate its surface area and round to the nearest hundredth for your final answer.
a. 125.63 sq. m
b. 113.04 sq. m
c. 120.3 sq.m
d. 123.8 sq.m
Answer:
B
Step-by-step explanation:
formula s =4*pi*r^2
s=4(3.14)(3^2)
s = 12.56(9)s= 113.04
Solve the inequality 171>-6x and graph the solution what does the graph look like
To solve the inequality, you need to isolate/get x by itself:
171 > -6x Divide -6 on both sides [dividing/multiplying a negative number on
-28.5 < x [dividing/multiplying a negative number in an inequality causes the sign (<, >, ≤, ≥) to flip]
-28.5 < x [x is a number greater than -28.5]
So your graph should have an open circle at -28.5 (the first small line next to -28), and the arrow pointing to the right since x is greater than -28.5 (increasing) The 1st option is your answer
[use the o---> and put it at -28.5]

Step-by-step explanation:
Simplifying:
-2(p + 4)² − 3 + 5p
-2(p² + 8p + 16) − 3 + 5p
-2p² − 16p − 32 − 3 + 5p
-2p² − 11p − 35
This is also the standard form.
Answer:
-2p^2 - 11 p - 35
Step-by-step explanation:
Please, use " ^ " to indicate exponentiation. Thus:
–2(p + 4)^2 – 3 + 5p
Now perform the exponentiation first, obtaining:
-2(p^2 + 8p + 16) - 3 + 5p, or
-2p^2 - 16 p - 32 - 3 + 5p
Now rearrange these terms in descending order by powers of p:
-2p^2 - 11 p - 32 - 3, or
-2p^2 - 11 p - 35

What is the equation of the line with an x-intercept of -2 and a y-intercept of 1
Answer:
y = 2x + 1
Step-by-step explanation:
This line goes through the points (-2, 0) (the x-intercept) and (0, 1) (the y-intercept).
As we move from -2 to 0, x increases by 2, and at the same time y increases from 0 to 1, that is, by 1. Thus, the slope of this line is m = rise / run = 2/1 = 2.
Starting with the slope-intercept formula for a straight line:
y = mx + b becomes y = 2x + 1. (We had already found b.)
The equation of line is x - 2y + 2 = 0.
What is Equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.
Here, x-intercept = -2
y- intercept = 1
Now, equation of line
x/a + y/b = 1
x/-2 + y/1 = 1
(x - 2y)/-2 = 1
x - 2y = -2
x - 2y + 2 = 0
Thus, the equation of line is x - 2y + 2 = 0.

The statement "If A, then B" can best be described as
O
A. If Ais false, then B must be false
O
B. If A is true, then B might be true.
O
C. If Ais false, then B might be false
D. If A is true, then B must be true.
Answer:
D
Step-by-step explanation:
This is called "implication". So if A (is true), then B MUST be true. If B is false, the implication is false. In all other cases, the implication is true. Suppose A is false, then it doesn't matter what B is, the implication is true, since we don't care what B is.
It's a bit confusing I suppose. Below is a truth table using P and Q in stead of A and B.
Final answer:
The correct answer is D: If A is true, then B must be true. This represents a logical conditional where the statement is true unless the antecedent A is true and the consequent B is false.
Explanation:
The statement "If A, then B" is a logical conditional, which can be represented as A
ightarrow B in logical notation. This statement best matches option D: If A is true, then B must be true. In logic, the only time a conditional statement is false is when the first part (the antecedent A) is true and the second part (the consequent B) is false. Otherwise, the statement is considered true, regardless of the individual truth values of A or B. This includes when A is false; the truth value of B does not affect the truth value of the conditional in this case. Therefore, if A is true, the conditional obliges B to also be true for the statement to remain true.

What is the x-value of the solution to the system of equations?
5x + 4y = 8
2x – 3y = 17
oooo
Answer:
x = 4
Step-by-step explanation:
Simplify the equation 5x + 4y = 8 to get y = 2 - [tex]\frac{5}{4}[/tex] x
then substitute the y into 2x - 3y = 17 to get the answer. sorry im not good at explaining but it should be right.
To find the x-value of the solution to the system of equations, we can use the method of substitution. Solve one equation for x, substitute it into the other equation, and solve for y. Finally, substitute the value of y back into the expression for x to find the x-value.
Explanation:To find the value of x in the system of equations, we can use the method of substitution. Firstly, solve one of the equations for x or y. Let's solve the second equation for x:
2x - 3y = 17 → 2x = 17 + 3y → x = (17 + 3y)/2
Now substitute this value for x into the first equation and solve for y:
5((17 + 3y)/2) + 4y = 8 → 17 + 3y + 4y = 8 → 17 + 7y = 8 → 7y = -9 → y = -9/7
Finally, substitute the value of y back into the expression we found for x:
x = (17 + 3(-9/7))/2 → x = (17 - 27/7)/2 → x = (119/7 - 27/7)/2 → x = 92/7/2 → x = 92/14 → x = 46/7
Therefore, the x-value of the solution to the system of equations is 46/7.

find the real zeros x4-11x2+18=0
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3
Final answer:
The real zeros of the polynomial equation x^4 - 11x^2 + 18 = 0 are found by factoring the equation as a quadratic in x^2, which yields the real zeros x = 3, x = -3, x = √2, and x = -√2.
Explanation:
To find the real zeros of the polynomial equation x4 - 11x2 + 18 = 0, we can attempt to factor it. Notice that the equation resembles a quadratic in form, with x2 taking the place of x. If we let y = x2, our equation becomes y2 - 11y + 18 = 0, which is a quadratic equation.
Factoring the quadratic equation gives us (y - 9)(y - 2) = 0. Thus, the solutions for y are y = 9 and y = 2. Since y = x2, we now solve for x by finding the square roots of these solutions.
For y = 9, the values of x are x = 3 and x = -3. For y = 2, the values of x are x = √2 and x = -√2. Therefore, the real zeros of the original polynomial equation are x = 3, x = -3, x = √2, and x = -√2.
