The conic section represented by the given equation is Circle.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Standard form of a circle is,
(x - h)² + (y - k)² = r²
where, (h, k) is the center of the circle and r is the radius of the circle.
Expanding, we get,
x² - 2hx + h² + y² - 2ky + k² = r²
x² - 2hx + y² - 2ky + (h² + k² - r²) = 0
The given equation is,
5x² – x + 5y² – 3y + 4 = 0
This is same as the standard form of the circle.
Hence the given equation is that of a circle.

Good luck on your quiz :)
Graph (a) represents an exponential decay.
Here, two graph are shown and we have to check which represent exponential decay.
What is exponential decay?
Exponential decay occurs when a quantity decreases by the same factor over equal intervals of time.
Now,
From the graph, we have
In graph (a), as x increases the function decreases.
Hence this graph shows exponential decay.
In graph (b), as x increases the function increases.

Isabel has just started a photo-sharing website and she is preparing for a presentation for an investor. Her site has 150 users and is growing by 25 users per day. Her competitor's site has 600 users and is growing by 10 users per day.
Answer: See Explanation
Step-by-step explanation:
Your question isn't well analysed but I guess that you want to calculate when both of them will have same number of users.
Let the number of days that both of them will have thesame number of competitors be x.
Therefore,
150 + 25x = 600 + 10x
25x - 10x = 600 - 150
15x = 450
x = 450/15
x = 30
They'll have same competitors by the 30th day.
The number of competitors will be:
= 150 + 25x
= 150 + 25(30)
= 150 + 750
= 900

Find the length of CD.
PLEASE HELP quickkkk
Answer: see below
Step-by-step explanation:
Just apply Proportionality Theorem at correct time, with correct proportions, It tells, the ratio of two corresponding arms always equal.
So, 1) AB/BC = AJ/JI
2.5/2.25 = AJ/1.8
AJ = 2.5* 1.8 / 2.25
AJ = 2
2) BC/CD = JI / IH
2.25/CD = 1.8/1.2
CD = 2.25 * 1.2 / 1.8
CD = 1.5
3) CD/DE = IH/HG
1.5/3.5 = 1.2 / HG
HG = 1.2 * 3.5 / 1.5
HG = 2.8
4) For GF, we should use "Pythagoras Theorem"
h² = a² + b²
GF² = 6.5² - 6²
GF² = 42.25 - 36
GF = √6.25
GF = 2.5
5) Perimeter = 2.5 + 2.25 + 1.5 + 3.5 + 6.5 + 2.5 + 2.8 + 1.2 + 1.8 + 2
P = 26.55
6) Area = 1/2 * b * h
A = 1/2 * 9.65 * 10.3
A = 49.70

What is Scatterplots?Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.
Given is a scatterplot.
A scatterplot is positive if an increase or decrease in one of the quantity results in the corresponding increase or decrease in the other quantity.
If it is opposite, then the relation is negative.
Here, when the x value increases, y value is also increasing.
So the relationship is positive.
A scatterplot show a linear relationship, if the values are closely resembling in a line.
Here the points are closely resembling on a line.
So it is linear.

Answer:
1) k = -10
2) n = -4
3) a = -9
Step-by-step explanation:
1) -4 = 6 + k
*we want to get k alone, so we will subtract 6 from both sides*
-4 = 6 + k
-6 -6
-10 = k
*in order to check this, we will plug the value we found for k, -10, into the original equation*
-4 = 6 + k
-4 = 6 + (-10)
-4 = -4
*this is correct because -4 = -4, so that is how we check*
2) -4n = 16
*we want n alone, we must divide by -4 on both sides*
-4n = 16
n = -4
*in order to check this, we plug what we found for n, -4, into the original equation*
-4n = 16
-4(-4) = 16
*a negative multiplied by a negative is a positive!*
16 = 16
*this is correct because 16 = 16*
3) 3/4a = -12
*we want a alone, so we will multiply by the negative reciprocal to get rid of the fraction on the left side*
a = -12 times 3/4
a = -9
*in order to check this, we will plug what we found for a, 9, into the original equation*
3/4a = -12
3/4 (-9) = -12
-12 = -12
*this is correct because -12 = -12*

A fast bi-level train travels from Washington, D.C. to Perryville Maryland. If this train traveled 75 miles in about .75 hours, what was the speed of the train
Answer:100 mph
Step-by-step explanation: it’s always distance divided by time. lol
The train travels to a distance of 75 miles in 0.75 hours, then the speed of the train will be equal to 100 miles per hour.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data mentioned in the question,
Distance (d) traveled by train = 75 miles
Time (t) taken by train to travel the distance = 0.75 hours
Then, use the equation of speed (s),
[tex]Speed =\frac{Distance}{Time}[/tex]
s = 75/0.75
s = 100 miles per hour.
