Which conic section is represented by the following equation? –5x2 10xy – 5y2 2x – y 4 = 0 circle ellipse parabola hyperbola.

Answers

Answer 1

A conic section can be an ellipse, a parabola or a hyperbola.

The equation of the conic section represents a hyperbola

How to determine the conic section

The equation of the conic section is given as:

[tex]\frac{-5x^2}{10} - \frac{5y^2}{2} = 1[/tex]

The equation of a hyperbola is represented as:

[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1[/tex]

By comparing the given equation of the conic section and the general equation of a conic section, we can see that both equations are similar in some aspect

Hence, the equation of the conic section represents a hyperbola

The population of fish in an aquarium can be modeled after exponential growth. If there were originally 3 fish and after 6 weeks there were 31 fish, how many fish would there be after 14 weeks?​

Answers

Answer:

The population in 14 weeks is 232 fishes

Step-by-step explanation:

The equation for exponential growth is f(x) = a·(1 + r)ˣ

Where;

a = The starting population size = 3

r = The rate at which the population of grows

x = The number of periods to of change of the population

Therefore, we have;

f(6) = 31 = 3 × (1 + r)⁶

31/3 = (1 + r)⁶

㏑(31/3) = 6㏑(1 + r)

(㏑(31/3))/6 =㏑(1 + r)

1 + r = e^((㏑(31/3))/6) ≈ 1.476

1 + r ≈ 1.476

Therefore, the population in 14 weeks is given as follows;

f(14) = 3 × (1.467)¹⁴ ≈ 232.574

Given that we the information is with regard of living things, such that there are no fractions, we round down to the nearest whole number as follows;

f(14) ≈ 232

The population in 14 weeks = 232 fishes.

im givin away myy last of points here is my question anyone can answer dis even people who just want points: Charise is buying 6 packets of seeds to plant in her garden. Each packet of seeds is $2.19. Estimate her total cost by rounding. Is the estimate an underestimate or an overestimate?

$12; underestimate
$18; underestimate
$12; overestimate
$18; overestimate

Answers

Answer:

It would be $12 overestimate

Step-by-step explanation:

$2.19 rounded to one significant figure would be $2.00

$2.00 multiplied by 6 would be $12

However since 19 cents is over $2, this means it's a definite overestimate

answer is sixteen (16)

Use PEMDAS, aka parenthesis, exponents, multiplication/division, addition/subtraction from left to right in order.

Start with the parenthesis and do the addition within the parenthesis.

Since you can do either multiplication or division before the other, read the equation from left to right and do it in that order.

Step-by-step explanation:

1. Write the following in exponential form and as a multiplication sentence using only 10 as a factor
(e.g., 100 = 102= 10 x 10).
a. 1,000
b. 100 x 100
2. Write the following in standard form (e.g., 4 x 102 = 400).
a. 3 x 102=
C.
800 - 103 =
I
b. 2.16 x 104 =
d. 754.2 - 102 =

Answers

Answer:

1. a. 1,000 = 10³ = 10 × 10 × 10

b. 100 × 100 = 10² × 10² = 10 × 10 × 10 × 10

2. a. 3 × 10² = 300

b. 2.16 × 10⁴ = 21,600

c. 800 ÷ 10³ = 0.8

d. 754.2 ÷ 10² = 7.542

Step-by-step explanation:

3. a. 1,000

There are 3 zeros in 1000. This is equivalent to 10 raised to the power of 3. Writing this in multiplication sentence using 19 as the only factor, we would have:

1,000 = 10³ = 10 × 10 × 10

b. 100 × 100

Using the same logic as explained in (a) above, we would have:

100 × 100 = 10² × 10² = 10 × 10 × 10 × 10

2. a. 3 × 10²

Convert 10² to 100 and multiply both numbers

3 × 10² = 3 × 10 × 10 = 3 × 100 = 300

b. 2.16 × 10⁴

2.16 × 10 × 10 × 10 × 10 = 2.16 × 10,000

Multiplying both numbers, since we have 4 zeros, move the decimal point 4 places to the right.

2.16 × 10,000 = 21,600

c. 800 ÷ 10³ = 800 ÷ 10 × 10 × 10

800 ÷ 1,000

There are 3 zeros in 1000, since we are dividing, move the decimal point 3 places to the left.

800 ÷ 1,000 = 0.8

d. 754.2 ÷ 10² = 754.2 ÷ 10 × 10

754.2 ÷ 100

Move the decimal point 2 places to the left.

754.2 ÷ 100 = 7.542

Step-by-step explanation:

The length of arc KNJ is the circumference of the entire circle minus the measure of the 48 degree arc.

How are the areas of the smaller squares related to the area of the biggest square? Do you notice something?



If a = the side of one small square and b = the side of the other small square and c = the side of the biggest square, then how could you write an equation using a, b, and c with exponents?

This is the Pythagorean Theorem for all Right Triangles. ____________________

Answers

Answer:

The sum of area of two smaller squares is equal to the area of bigger square

An equation using a, b, and c with exponents is [tex]c^2=a^2+b^2[/tex]

Step-by-step explanation:

Let a be the side of the smallest square , b be the side of other smaller square and c be the side of biggest square

Area of square with side a = [tex]Side^2 = a^2[/tex]

Area of square with side b = [tex]Side^2 = b^2[/tex]

Area of square with side c =[tex]Side^2 = c^2[/tex]

Refer the attached figure

In triangle ABC

[tex]\angle A = 90^{\circ}[/tex]

So, We can use Pythagoras theorem over here

AB = a = Base

AC = b = Perpendicular

BC = c = Hypotenuse

[tex]Hypotenuse^2=Perpendicular^2+Base^2\\c^2=a^2+b^2[/tex]

So, The sum of area of two smaller squares is equal to the area of bigger square

An equation using a, b, and c with exponents is [tex]c^2=a^2+b^2[/tex]

An experiment involves rolling a standard die. The experiment was performed 100 times, and the results are shown in the following frequency table. Result Frequency 1 14 2 19 3 16 4 16 5 17 6 18 What is the experimental probability of rolling a 1?

Step-by-step explanation:

first a quick check that we really deal with 100 events (experiment results).

14+19+16+16+17+18 = 100

perfect.

so, based on this particular die its own probabilty distribution of the 6 different possible outcomes shows that there might be some imbalances inside the die, or its outside dimensions are not exactly the same, or simply the process of rolling the die is not neutral (not fully random).

in any case, it seems there are some deviations from the normal expected behavior of 1/6 per number.

so, the observed experimental probabilty of rolling a 1 is

A designer is adding a pendant to a jewelry collection. The shape of the pendent can be defined by the equation y = StartFraction 1 Over 20 EndFraction x squared EndFraction. If the largest dimension of the pendant is 10 cm wide, what is the greatest length? 1. 25 cm 2. 50 cm 5 cm 10 cm.

Answers

The greatest length of the considered pendent is given by: Option A: 1.25 cm

What does graph of a function represents?

Suppose the considered function is [tex]y = f(x)[/tex]

Then, we will plot points as [tex](x,y) =(x,f (x))[/tex] for all values of 'x' which are in domain of the function.

For this case, the given function's graph (the graph of [tex]y = \dfrac{x^2}{20}[/tex] ) is shown below.

We're given that the largest dimension is of 10 units.

Let this be the line segment parallel to the x-axis, intersecting y-axis at [tex]y = y_0[/tex]

Now, since the curve is symmetric over (as for x or -x, we get same y), so the line segment that is parallel to x axis also intersects the graph at symmetric places. Let those points be in front of [tex]x_0[/tex] and [tex]-x_0[/tex]

For those inputs, the output is [tex]y = y_0[/tex],

Also, we have length of the line segment as of 10 units, this is the difference between those symmetric inputs.

Thus, we get two equations:

[tex]x_0 - (-x_0) = 10[/tex]

[tex]f(x_0) = y_0 = \dfrac{x_0^2}{20}[/tex]

From first one, we get:

[tex]x_0 = 10/2= 5[/tex]

Thus, we get:

[tex]f(x_0) = y_0 = \dfrac{x_0^2}{20}\\\\f(5) = y_0=\dfrac{25}{20} = 1.25[/tex]
Since the length of y_0 is the shortest distance from x-axis to that parallel line segment, this is the second dimension needed.

Thus, the greatest length of the considered pendent is given by: Option A: 1.25 cm
