Answer:
a = 9
Step-by-step explanation:
For solve the problem we can use the Pythagorean theorem in this way
a^2 + (3√3)^2 = (6√3)^2
If we solve the equation we have
a^2 + 27 = 108
a^2 = 81
a = +/-9
we take only the the positive value because a length can’t be negative
a = 9

Step-by-step explanation:
a = piR^2
The area of a sector of a given circle is 37.7 m².
Given that, the radius of a circle=4 m and the central angle of a circle=270°.
What is the formula to find the area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula to find the area of a sector is θ/360°(πr²).
Where r is the radius of the circle and θ is the angle of the sector.
Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².
Therefore, the area of a sector of a given circle is 37.7 m².

find the measure of arc VF. (look at the picture provided) please help
Answer:
60degrees
Step-by-step explanation:
Using the theorem that states that angle at the vertex is half the difference of the angles at the intercepted arcs
Angle at vertex can be gotten by taking the difference of 119 and 65
Angle at the vertex = 119 - 65
Angle at the vertex = 54
Hence;
54 = 1/2(168-VF)
Cross multiply
54 * 2 = 168-VF
108 = 168 - VF
VF = 168 - 108
VF = 60degrees
Hence the measure of arc VF is 60degrees

Explain how you went about finding a solution to the problem. We want to go to zoo. 7 adult tickets and 7 kids tickets equal 50 dollars. Adult tickets are twice as expensive as the kid’s ticket. How much do the tickets cost?
Answer:
Cost of Kid's tickets =16.66
Cost of Adult's ticket =33.34
Step-by-step explanation:
Adult Tickets=7
Kids Tickets=7
Both total = 50$
So 14 tickets =50$
Now: Lets the cost of kid's ticket=x
The Cost of Adult's tickets be 2x
=so (x+2x)=50$
=3x=50$
=x=16.67 for 7tickets
Cost of Kid's tickets =16.66
Cost of Adult's ticket =33.34

AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10

PLEASE HELP !!!!!!! what is the coordinate of the vertex of the following parabola: (x-1)^2=12(y+2)
a. (-1, 2)
b. (1, 2)
c. (1, -2)
d. (0, 12)
The coordinate of the vertex of the parabola is option (C) (1,-2) is the correct answer.
What is the equation of the parabola?The set of all points in a plane that are equidistant from a fixed line and a fixed point (not on the fixed line) in the plane is a parabola. The fixed line is the ‘directrix’ and the fixed point is the ‘focus’. The point of intersection of the parabola with the axis is the vertex.
For the given situation,
The equation of parabola is [tex](x-1)^2=12(y+2)[/tex] ------ (1)
The diagram below shows the parabola and the vertex of the equation of parabola.
The general form of the equation of parabola is
[tex](x-h)^{2} =4a(y-k)[/tex]
Here the vertex is (h,k)
Now compare the equation 1 with this general form, we get
⇒ [tex]h=1[/tex] and [tex]k=-2[/tex]
Hence we can conclude that the coordinate of the vertex of the parabola is option (C) (1,-2) is the correct answer.
