Which equation represents the parabola shown on the graph?
y2 = 1.5x
x2 = 1.5y
y2 = 6x
x2 = 6y
The equation represents the parabola is x² = 6y.
What is Equation of Parabola?Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. The topic of conic sections includes parabola, and all of its principles are discussed here.
The general equation of a parabola is given by y = a(x – h)² + k
We have equations.
The graph's parabola is a vertical parabola that is open vertically and has its vertex at the origin.
So, the equation of the parabola is equal to
x² = 4ay...............(1)
and, the equation of the directrix is y= -a.
her, the directrix is y= -1.5
Now, the equation for the parabola is
x² = 4(1.5)y
x² = 6y

You are going to design a deck or a dock for your cottage. Your deck/dock must be a composite shape made out of 3 shapes - 2 will be "glued” together and 1 will be "cut out” of the other(s). You must use 3 different geometric shapes. Design your deck/dock by including a diagram with
measurements. Make sure your measurements are realistic! You will need material to make your deck/dock so determine the area of your deck/dock so you will know how much material you will need and how much space you will have to use.

Find the value of x.
Answer:
8
Step-by-step explanation:
6x+1 = 9x-23
add 23 to both sides
subtract 6x from both sides
3x=24
x=8
Answer:
8 =x
Step-by-step explanation:
The angles are the same so
6x+1 = 9x-23
Subtract 6x from each side
6x+1-6x = 9x-6x-23
1 = 3x-23
Add 23 to each side
1 +23 = 3x-23+23
24 = 3x
Divide by 3
24/3 = 3x/3
8 =x

In the year 2006, a person bought a new car for $18000. For each consecutive year after that, the value of the car depreciated by 15%. How much would the car be worth in the year 2009, to the nearest hundred dollars?
Please i need answer now
Answer:
Step-by-step explanation:
Use the exponential function
[tex]v(t)=a(b)^t[/tex] where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:
[tex]v(t)=18000(.85)^t[/tex] We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):
[tex]v(t)=18000(.85)^3[/tex] and simplifying a bit:
v(t) = 18000(.614125) so
v(t) = 11054.25
Round however you need to.

Joan is buying airline tickets for her family. Each airline ticket costs $232 with a baggage fee of $13. The airline
charges a booking fee of $45 for the entire set of tickets. Joan spent a total of $1,515. If x represents the number of
tickets, which equation can be used to find the value of x?
O 245+45x = 1,515
O 232x+45x - 1,515
O 232x+45= 1,515
452455
Answer:
232x + 45 = 1,515
Step-by-step explanation:
45 is a one time fee for book several tickets at one. 232 is the cost of each ticket and 232 get x because we dont know how many family members Joan bought tickets for.

Suppose the 100 people in society X all know the same 10 facts, while the 10 people in society Z specialize, with each person knowing 5 unique facts as well as 5 facts also known by the other 9 members of the society. If the standard of living is roughly equivalent to the average number of social facts known per person, which society has a higher standard of living
Answer:
29 times
Step-by-step explanation:
Given :
Society X ;
Population = 100
Number of facts known = 10
Average fact known per person = known fact / population = 10 / 100 = 0.1
Society X:
Population = 19
Common fact known by 9 = 5
Specialized fact, known by 10 = 5 * 10 = 50
Total facts = common + specialized = 55
Average fact known per person = 55 / 19 = 2.8947368 fact per person
Number of times society Z is better :
2.8947368 / 0.1 = 28.947 times
Approximately 29 times

Zeyad has a bag of 40 marbles. 10 of them are red. 12 are blue. 18 are white. He reaches into the bag without looking. What is the probability that Zeyad will select a white marble?
Answer:
9/20
Step-by-step explanation:
There are 40 marbles
18 are white
P( white marble) = number of white marbles / total number of marbles
= 18/40 = 9/20
if GJ = 11a and IJ = a + 10, find the value of a that makes quadrilateral FGHI a parallelogram
Note: Consider J is the intersection point of diagonals of quadrilateral FGHI.
Given:
[tex]GJ=11a[/tex]
[tex]IJ=a+10[/tex]
To find:
The value of a that makes quadrilateral FGHI a parallelogram.
Solution:
We know that the diagonals of a parallelogram bisect each other.
If FGHI is a parallelogram and J is the intersection point of diagonals, then
[tex]GJ=IJ[/tex]
[tex]11a=a+10[/tex]
[tex]11a-a=10[/tex]
[tex]10a=10[/tex]
Divide both sides by 10.
[tex]a=\dfrac{10}{10}[/tex]
[tex]a=1[/tex]
Therefore, the required value of a is 1 units.
