The standard form of the circle equation 4x² + 8x + 4y² + 32y +52 = 0 is (x + 1)² + (y + 4)² = 2²

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have an equation that represents the circle:

4x² + 8x + 4y² + 32y +52 = 0

Divide by 4 on both the sides:

x² + 2x + y² + 8y + 13 = 0

x² + 2x + 1 - 1 + y² + 8y + 4² - 4² + 13 = 0

x² + 2x + 1 + y² + 8y + 4² - 1 - 16 + 13

(x + 1)² + (y + 4)² = 4

(x + 1)² + (y + 4)² = 2²

Thus, the standard form of the circle equation 4x² + 8x + 4y² + 32y +52 = 0 is (x + 1)² + (y + 4)² = 2²

Answer:

sub(2，-6)into y=mx+C

-6=-1(2)+C

C=-4

equation=y=-x-4

Answer:

y = -x - 4

Step-by-step explanation:

Given:

a line with a slope of -1, passing through the point (2,-6)

Point-Slope Form: y - y₁ = m(x - x₁)

where:

(x₁, y₁) is the given point

m is the slope

Substitute the given values into the formula:

⇒ y - y₁ = m(x - x₁)

⇒ y - (-6) = -1(x - 2)

⇒ y + 6 = -1(x - 2) [distribute -1 through the parentheses]

⇒ y + 6 = -x + 2 [subtract 6 from both sides]

⇒ y + 6 - 6 = -x + 2 - 6

⇒ y = -x - 4

Check your work:

⇒ y = -x - 4 [substitute 2 for x, and -6 for y]

⇒ -6 = -2 - 4 [simplify]

⇒ -6 = -6 ✔

Therefore, the equation of the line is: y = -x - 4

3x^{2} -16x-19

Step-by-step explanation:

If we are going to be simplying this problem, then we need to take it step by step.

Start off by using the distributive property, and then combining like terms. Keep in mind the square, and make sure that gets sorted out correctly.

Answer:

(3x - 19) • (x + 1)

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

((3•((x-5)2))+14•(x-5))-24

STEP

2

:

Equation at the end of step 2

(3 • (x - 5)2 + 14 • (x - 5)) - 24

STEP

3

:

Trying to factor by splitting the middle term

Factoring 3x2-16x-19

The first term is, 3x2 its coefficient is 3 .

The middle term is, -16x its coefficient is -16 .

The last term, "the constant", is -19

Step-1 : Multiply the coefficient of the first term by the constant 3 • -19 = -57

Step-2 : Find two factors of -57 whose sum equals the coefficient of the middle term, which is -16 .

-57 + 1 = -56

-19 + 3 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -19 and 3

3x2 - 19x + 3x - 19

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (3x-19)

Add up the last 2 terms, pulling out common factors :

1 • (3x-19)

Step-5 : Add up the four terms of step 4 :

(x+1) • (3x-19)

Which is the desired factorization

The only problem is you may also go bankrupt before you're able to double your bet enough times.

If the game's events are independent,  similar to flipping a coin,  then the probability never changes, it's still a 1 out of 5 chance of winning each time.

The coin has no memory,  so it will always have the same probability on each flip.

If the games' events are like that,  a losing streak doesn't mean a win is now more likely.

But if the events are not independent,  it may make sense to increase the bet.  

for example,  a bag has 10 coins and 2 are worth 100.  You reach in and pull out 5 coins, all worth only a penny each.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Your odds of getting one of the 2 $100 coins is now much greater than the original 1 out of 5 chance.

 You originally had a 2 out of 10 chance on the first draw.  But now it's up to 2 out of the remaining 5 or 40% chance of winning.  

There is another reason someone may wish to double their bet.  If you doubled your bet each time you lost,  you would eventually recoup all your losses.  It can work.

The only problem is you may also go bankrupt before you're able to double your bet enough times.

That risk is usually considered too great to double your bets on independent events.

After all the conditions you applied from the statement given you will get the original number as 16.08.

An algebraic equation is when two expressions are set equal to each other, and at least one variable is included.

Given that, if you subtract 0.3 from a certain number, add 0.4 times the original number to the result and then add another 2.78, you'll get 25.

We need to find the original number.

Let us take the original number as x.

Now, subtract 0.3 from the original number.

That is x-0.3.

0.4 times the original number is 0.4x.

Add 0.4 times the original number to the result.

That is, x-0.3+0.4x=1.4x-0.3

Now, add 2.78 to the result. That is 1.4x-0.3+2.78=1.4x+2.48.

As a result, you'll get 25. That is 1.4x+2.48=25

⇒1.4x=22.52

⇒x=16.08

Therefore, the equation of the hyperbola with a given origin has vertices at (0, ±9) and foci at  (0, ±10) is [tex]\frac{x^{2} }{81}-\frac{y^{2} }{19} =1[/tex].

Given, that a hyperbola centred at the origin has vertices at (0, ±9)  and foci at  (0, ±10).

In mathematics, a hyperbola is a type of smooth curve lying in a plane, defined by its geometric properties or by equations for which it is the solution set. A hyperbola has two pieces, called connected components or branches, that are mirror images of each other and resemble two infinite bows.

The formula for a hyperbola centred at the origin is [tex]\frac{(x-h)^{2} }{a^{2} } -\frac{(y-k)^{2} }{b^{2} } =1[/tex]

Where (h, k) is the center = (0, 0)

Distance from centre to vertices a = 9 ⇒ a² = 81

Distance from centre to vertices which is given from the foci c = 10

⇒ c² = 100

Using the Pythagorean formula, c²= a²+ b²

Substituting the values 100 = 81 + b²

So we get, b²= 100 - 81 = 19

Substituting the values in the standard form [tex]\frac{x^{2} }{81}-\frac{y^{2} }{19} =1[/tex].

Therefore, the equation of the hyperbola with a given origin has vertices at (0, ±9) and foci at  (0, ±10) is [tex]\frac{x^{2} }{81}-\frac{y^{2} }{19} =1[/tex].

Answer:

[tex]f(4)=e^{4}-3[/tex]   or   [tex]f(4)\approx51.5981500331...[/tex]

Step-by-step explanation:

The following is a general explanation of functions, what they mean, and how to evaluate them.  The simplifications and calculations at the end are based on the clarification from your comments that [tex]f(x)=e^{x}-3[/tex] .  If [tex]f(x)[/tex] is equal to something else, the simplifications/calculation will obviously be a little different, and the answer will likely be different, but the general process will be the same.

In the equation [tex]f(x)=e^{x}-3[/tex] , the left side of the equation is saying several things at once.

Names

The first character, "f", is the name of the function.

The name of a function tells you which set of directions you should look for to apply to an input.  Some functions have names that are more than one letter, and even might give a hint as to what they do, for instance I might name a certain function [tex]squareroot[/tex], and based on the name, you might guess what the equation for [tex]squareroot(x)[/tex] might look like.

Mathematicians often use "f" as a function name between different problems over and over and over again, unless they come up with a special function that is worth giving a special name to.  

Input

The rest of the characters after the name of the function, are "(x)" which is a pair of parentheses to contain the input, and the input itself.

Again, mathematicians often use "x" as a generic input over and over and over again, until we actually know which number we want to put into the function.

Output

Even though we've already discussed every character in the notation on the left, there is actually one more thing that the left side of the equation is saying:  Altogether, "f(x)" is the output of the function, when the input "x" is put in.  I feel it's worth stating, because it's often glossed over.

The equation itself

Next in the equation is the equals sign, which means that the left side of the equation, which is the output "f(x)", is equal to the stuff on the right.

The right side of the equation is the rule to follow describing what f(x) does to an input, and can help you calculate the output.

For instance, if I asked what p(4) was, it is clear that there is an input of 4, but without knowing what the function "p" does, there's no way to know what the function will give as an output when one inputs "4".  This is why the right-hand side of the equation for a function is important.

To evaluate any function, we take an input, apply the function, and simplify/calculate the output.

In this case, the question asks for [tex]f(4)[/tex], meaning that the "input" is "4".  

In this case, the question gives an explanation of what the function does through a rule given in equation form.

Given your clarification of the given function,  [tex]f(x)=e^{x}-3[/tex] , meaning a generic input (in this case "x") is put into the function "f" and the output is found by doing the arithmetic on the right side of the equation (exponentiating the number by "e", and then subtracting 4)

Notice that in the expression  [tex]f(4)[/tex], the "x"  was replaced with "4".  So, we need to substitute "4" where we see an "x" in the rule on the right hand side of the equation rule, and simplify and/or calculate (calculate, like with a calculator)

So, to evaluate the expression [tex]f(4)[/tex], simply substitute, and simplify/calculate.

Simplifying (no calculator)

To simplify without a calculator, we substitute "4".  Any time you make a substitution, use parentheses.  Then, try to simplify.

[tex]f(4)=e^{(4)}-3[/tex]

[tex]f(4)=e^{4}-3[/tex]

As it turns out, this is as much as we could simplify things here (without a calculator).  So, if an exact answer is needed, this would be it.

Calculating (with a calculator)

To calculate with a calculator, we substitute "4".  Any time you make a substitution, use parentheses.  Then, try to simplify.

[tex]f(4)=e^{(4)}-3[/tex]

[tex]f(4)=e^{4}-3[/tex]

[tex]f(4)=54.5981500331...-3[/tex]

[tex]f(4)=51.5981500331...[/tex]

So calculating with a calculator, the output of the function "f", for an input of "4", is approximately 51.598.
