Find the value of X in this hexagon
Answer:
x = 130°
Step-by-step explanation:
number of sides = 6
the sum of the total interior angles = (6 x 180) - 360 = 720°
x = 720 - 125 - 120 - 100 - 120 - 125 = 130°

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.

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

Answer:
79 degrees.
Step-by-step explanation:
There are 7 total temperatures, 68, 82, 81, 82, 74, 75, and 91 degrees. To find the mean, we add all of the temperatures together and divide it by the number of tempuratures-- 7.
68+82+81+82+74+75+91 = 553.
553 / 7 = 79.

Graph y = x2 - 8x + 13
Answer:
Step-by-step explanation:
From the given x^2 - 8x + 13 we can find several points to graph to represent this quadratic function.
The y-intercept is (0, 13) and stems from letting x = 0.
b
The axis of symmetry is x = - -----
2a
-8
Since a = 1 and b = -8, the axis of symmetry is x = - ------- = 4
2(1)
and so the vertex is at (4, 4^2 - 8(4) + 13), or (4, -3)
If you want to go the extra mile, find the roots of the given equation. These are also your x-intercepts. One such intercept is (2. 0).
Plot these points and draw a smooth curve through them.

8a-3=8a+35
-8a -8a
-3 does not equal to 35
NO SOLUTIONS
Answer: 8a=38+8a²
Step-by-step explanation:
8a-3=5(a+7)+3a
8a-3=5a+35+3a
8a-3=8a²+35
8a=35+3+8a² (I moved 3 to put it with 35 because they are the same, I couldn't do the same for 8a and 8a² because of the 2)

Quintaveous’s father gave him a baseball card collection for his birthday. He told
Quintaveous that its current value is $250 and that each year the value will grow at
a rate of 10%. What is the approximate value of the card after 6 years?
Group of answer choices
$310
$500
$133
$443
Answer:
the approximate value after 6 years is $443
Step-by-step explanation:
The computation of the approximate value after 6 years is shown below:
= Current value × (1 + rate of interest)^number of years
= $250 × (1 + 0.10)^6
= $250 × 1.1^6
= $442.8903
= $443
Hence, the approximate value after 6 years is $443
Therefore the last option is correct

You roll a 6-sided die.
What is P(5)?
Answer:
1/6
Step-by-step explanation:
you have a 6 sided die that is numbered 1, 2, 3, 4, 5, and 6.
you roll it once, so the probability that you will roll a five is 1/6
this is because you only want one specific number so that goes on the numerator of the fraction.
then, you have to multiply how many sides you have on the die to the number of rolls. in this case we have one roll and six sides. so the six goes on the denomerator side of the fraction

Give your answer as an integer.
Answer:
8 m/s.
Step-by-step explanation:
18 miles = 18*8/5 = 28.8km
28.8 km = 28.8 * 1000
= 28,800 m.
There are 3600 seconds in an hour.

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.
