[tex]\large\boxed{x^2+y^2-10x+6y-47=0}[/tex]

Step-by-step explanation:

The equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have the center (5, -3) and the radius r = 9.

Substitute:

[tex](x-5)^2+(y-(-3))^2=9^2\\\\(x-5)^2+(y+3)^2=81[/tex]

Use

[tex](a\pm b)^2=a^2\pm2ab+b^2[/tex]

[tex]x^2-2(x)(5)+5^2+y^2+2(y)(3)+3^2=81\\\\x^2-10x+25+y^2+6y+9=81\\\\x^2+y^2-10x+6y+(25+9)=81\\\\x^2+y^2-10x+6y+34=81\qquad\text{subtract 81 from both sides}\\\\x^2+y^2-10x+6y-47=0[/tex]

Here Angle O is equal to Angle O as they are vertical angles across a vertex.

Answer:

The correct option is 2.

Step-by-step explanation:

From the given figure it is clear that the lines DE║RK, in triangle ODE and triangle OKR,

[tex]\angle DOE=\angle KOR[/tex]                         (Vertical opposite angles)

[tex]\angle ODE=\angle OKR[/tex]                         (Alternate interior angles)

[tex]\angle OED=\angle ORK[/tex]                         (Alternate interior angles)

By using AA property of similarity,

[tex]\triangle DOE\sim \triangle KOR[/tex]

D is correspondence to K, O is correspondence to O, E is correspondence to R.

O ↔ O

Therefore the correct option is 2.

Answer:

8 - 2x

Step-by-step explanation:

|2x -8| , x < 4

Two conditions:

(a) |2x - 8| =   (2x - 8) if (2x - 8) ≥ 0

(b) |2x - 8| = -(2x - 8) if (2x - 8) < 0

If x < 4, (2x - 8) <0, so condition (b) applies.

|2x - 8| = -(2x - 8) or

|2x - 8| = 8 - 2x

The equivalent expression is 8 - 2x.

[tex]lim_{x \to \: 0}( {x}^{2} - 1) = - 1[/tex]

EXPLANATION

The given limit is

[tex] lim_{x \to \: 0}( {x}^{2} - 1) [/tex]

To evaluate this limit by direct substitution,

We put x=0 in the function.

This implies that that ,

[tex] lim_{x \to \: 0}( {x}^{2} - 1) = {0}^{2} - 1[/tex]

This simplifies to,

[tex] lim_{x \to \: 0}( {x}^{2} - 1) = 0 - 1[/tex]

[tex] lim_{x \to \: 0}( {x}^{2} - 1) = - 1[/tex]

This means that as x-values approach zero, the function approaches -1.

Answer:

-1

Step-by-step explanation:

For direct substitution, all you have to do is fill in the limit for x and solve... so the limit would be 0 in this case.

The answer is Undefined

Answer:

undefined

Step-by-step explanation:

The y-axis is a vertical line.

The point [tex](0,y_1)[/tex] and[tex](0,y_2)[/tex] lies on the y-axis.

The slope of this line is

[tex]=\frac{y_2-y_1}{0-0}[/tex]

[tex]=\frac{y_2-y_1}{0}[/tex]

Division by zero is undefined.

All vertical lines have undefined slopes because they are parallel to the y-axis.

Therefore the slope of m is undefined.

Answer:

Part 1) [tex]a^{b+2}=(x)(a^{2})[/tex]

Part 2) [tex]2a^{3b}+a^{2b}+a^{b}=2x^{3}+x^{2}+x[/tex]

Step-by-step explanation:

Part 1) Given that [tex]a^{b}=x[/tex] evaluate the following

[tex]a^{b+2}[/tex]

we know that

[tex]a^{b+2}=(a^{b})(a^{2})[/tex]

Remember that when multiplying two powers that have the same base, you can add the exponents

[tex]a^{b}=x[/tex]

so

substitute

[tex]a^{b+2}=(x)(a^{2})[/tex]

Part 2) Given that [tex]a^{b}=x[/tex] evaluate the following

[tex]2a^{3b}+a^{2b}+a^{b}[/tex]

we know that

[tex]2a^{3b}+a^{2b}+a^{b}=2(a^{b})^{3}+(a^{b})^{2}+a^{b}[/tex]

Remember that

[tex]a^{b}=x[/tex]

so

substitute

[tex]2a^{3b}+a^{2b}+a^{b}=2x^{3}+x^{2}+x[/tex]

The answer is 5.55

Step-by-step explanation:

To round 5.5454 to 2 decimal places, you look at the third and fourth decimal places. Since the digit in the fourth decimal place is 5 or greater, you round up the digit in the third decimal place, resulting in 5.55.

To round 5.5454 to 2 decimal places, we look at the digit in the third decimal place (5) and the digit in the fourth decimal place (4). Since the digit in the fourth decimal place is 5 or greater, we round up the digit in the third decimal place.

The rounded value will be 5.55.

Therefore, 5.5454 rounded to 2 decimal places is 5.55.

Answer:

Last option: [tex]A=2\pi rh[/tex]

Step-by-step explanation:

 If  the shell of a bass drum was cut down one side and laid flat, the resulting shape would be a rectangle.

The area of a rectangle can be calculated with the formula:

[tex]A=l*w[/tex]

Where l is the lenght and w is the width.

In this case, the lenght of the rectangle obtained (the lenght of the shell)  is the circumference of the drum.

Remember that the circumference of the circle can be calculated with:

[tex]C=2\pi r[/tex]

Where r is the radius of the circle.

Then:

[tex]l=2\pi r[/tex]

The width is the height of the shell:

[tex]w=h[/tex]

Then, substituting into [tex]A=l*w[/tex], you get:

[tex]A=2\pi rh[/tex]

The number of angles that are alternate exterior angles with angle 5 is equal to 1.

In Mathematics,  parallel lines are two lines that are cut through by a transversal and they always have the same (equal) distance apart and never meet.

In Mathematics, the alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed lie outside the two (2) parallel lines, are located on opposite sides of the transversal, and are congruent angles.

In conclusion, we can logically deduce that both m∠5 and m∠11 are alternate exterior angles because they lie outside the two (2) parallel lines and are located on opposite sides of the transversal.

50x2=x

50 represents the red candies.

2 represents the other half of candies.

x represents the total amount of candies.

Hope this helps!

The equation representing the total number of candies in Meghan's jar, where x is the total, is x/2 = 50, giving us 100 candies in total. For Jenny's chocolates, Jenny initially had 14 chocolates before she ate two and gave half of the remaining to Lisa.

If Meghan discovered that half of the candies were red and she had 50 red candies, then to find the equation representing the total number of candies in the jar, we assign x to represent the total number. Since half of x is 50, the equation is x/2 = 50. To find x, we multiply both sides of the equation by 2, resulting in x = 100. Therefore, Meghan has 100 candies in total in her jar.

To address the question about Jenny and her chocolates: Initially, Jenny has some number of chocolates. When she eats two chocolates and gives half of the remainder to Lisa, and Lisa ends up with six chocolates, we can determine how many Jenny started with. Lisa's six chocolates represent half of what remained after Jenny ate two, which implies there were 12 before giving to Lisa, and so initially, Jenny had 14 chocolates.

Step-by-step explanation:

Sony paid for two scarves = $ 25

We are given that one scarf cost $3 more than the other

Let the cost of one scarf be x

So, cost of another scarf = x+3

Since the total cost is $25

So, [tex]x+x+3=25[/tex]

[tex]2x+3=25[/tex]

[tex]2x=22[/tex]

[tex]x=\frac{22}{2}[/tex]

[tex]x=11[/tex]

So, cost of one scarf = $11

Cost of another scarf = x+3=11+3=14

Hence the cost of the expensive scarf is $14

False. Correct equation: [tex]\(2n - 7 = -5\)[/tex]. Your proposed equation [tex]\(7 - 5n = -5\)[/tex] does not accurately represent the relationship.

The answer is False.

Here's why:

1. The statement "seven less than twice a number" can be represented as [tex]\( 2n - 7 \)[/tex], where [tex]\( n \)[/tex] is the number.

2. The equation for "seven less than twice a number is negative five" should be [tex]\( 2n - 7 = -5 \)[/tex], as the phrase "is negative five" translates to the equation being equal to [tex]\( -5 \)[/tex].

3. Your proposed equation, [tex]\( 7 - 5n = -5 \)[/tex], is incorrect because it represents a different relationship. It suggests that [tex]\( 7 \)[/tex] subtracted by [tex]\( 5n \)[/tex] is equal to [tex]\( -5 \)[/tex], which does not align with the given statement.

4. To correct the equation, simply rewrite it as [tex]\( 2n - 7 = -5 \)[/tex], which accurately represents the relationship described in the statement.

Therefore, the statement is false because the given equation does not correctly represent the phrase "seven less than twice a number is negative five."
