Using the given information, the equation of the circle with radius 2 and center at (-1 , -5) is (x + 1)^2 + (y + 5)^2 = 4.

The general form of the equation of  circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the general form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (-1 , -5)

r = 2

(x - -1)^2 + (y - -5)^2 = 2^2

(x + 1)^2 + (y + 5)^2 = 4

Step-by-step explanation:

Answer:

7th term = (-1)

rule for the nth term = an = a+(n-1)d

Step-by-step explanation:

a = 5, d = a2-a1 = 4-5 = -1, n = 7

an = a+(n-1)d

a7 = 5+(7-1)(-1)

a7 = 5-6

a7 = (-1)

The equation in slope-intercept form is x – 5y = -12

Given,

y = -5x – 8

This is in slope-intercept form, y = mx + b

Where, m is slope and b is y-intercept.

Here, m = -5

Perpendicular lines have slopes that are negative reciprocals, [tex]m_{p}[/tex] = -1/m

Here we need equation of line through (-2, 2) with slope -1/-5 = 1/5

y = (1/5)x + b

where (-2, 2) is on the line.

2 = 1/5(-2) + b

2 = -2/5 + b

b = 2 + 2/5 = 12/5

therefore, equation we need is:

y = 1/5x + 12/5

that is,

1/5x – y = -12/5

Multiplying 5 in both sides, we get

5(1/5x) – 5y = (-12/5)5

That is, the equation we need is:

x – 5y = 12

A triangle is a shape whose all three angles have a sum of 180 degrees. So from the above definition we know that:

P + Q + R = 180

Q=3P

T=P + 20

Therefore:

P + 3P + P + 20 = 180

5P + 20 = 180

5P = 160

P = 32

Q = 3(32) = 96

R = 32 + 20 = 52

By using the fact that the two angles whose measures are expressed in terms of x are vertical angles, we will see that x = 8.

Then using that we will see that the measure of angle BAC is 63 degrees.

On the given diagram, we can see that the two angles whose measures are expressed in terms of x are vertical angles, thus, these two angles have the same measure, then we can write a linear equation that helps us to find the value of x, which is:

(2x + 3) = (4x - 5)

Solving the linear equation for x we get:

2x + 3 = 4x - 5

3 + 5 = 4x - 2x

8 = 2x

8/2 = x = 4

So we can see that the value of x is 4.

Now we want to find the measure of angle BAC.

We can see that the measure of angle BAC plus the measure of the angle to its right will be a right angle, then we can write:

m∠BAC + (4x - 5)° = 90°

Replacing the value of x we get:

m∠BAC + (4*8 - 5)° = 90°

m∠BAC + 27° = 90°

m∠BAC = 90° - 27° = 63°

We conclude that the measure of angle BAC is 63 degrees.

Based on the elevation that the mountaineer has to climb of 6,282 meters, supplementary oxygen is needed because this distance is above 18,000 feet.

The limit for what is considered extremely high altitude is given in feet so the mountaineer's elevation of 6,282 meters needs to be converted to feet.

1 meter in feet is 3.28084 feet.

6,282 meters in feet is therefore:

= 6,282 x 3.28084

= 20,610.24 feet

This distance is more than the 18,000 feet above sea level which makes it extremely high altitude and so supplementary oxygen is needed.

Step-by-step explanation:

Let's solve your system by substitution.

7a−12b=10;−2a−4b=12

Step: Solve7a−12b=10for a:

7a−12b=10

7a−12b+12b=10+12b(Add 12b to both sides)

7a=12b+10

7a/7=12b+10/7

(Divide both sides by 7)

[tex] \sf \: a = \frac{12}{7} b + \frac{10}{7} [/tex]

Step: Substitute: 12/7b+10/7 for a in−2a−4b=12:

−2a−4b=12

−2(12/7b+10/7)−4b=12

−52/7b + −20/7=12(Simplify both sides of the equation)

−52/7b+−20/7+20/7=12+20/7

(Add 20/7 to both sides)

−52/7b=104/7

[tex] \sf \: \frac{ \frac{ - 52}{7}b }{ \frac{ - 52}{7} } = \frac{ \frac{104}{7} }{ \frac{ - 52}{7} } [/tex]

(Divide both sides by (-52)/7)

b=−2

Step: Substitute −2 for b in a =12/7b+10/7:

The quotient in this Carl multiplies the both value instead of dividing so that is the mistake that made by Carl.

The quotient of 4 divided by 2 1/3 and also explain the mistake that done by Carl

The value of 4  1/3 is 14/3

And the value of 2  1/3 is 7/3

So then we divide 4 2/3 by 2 1/3 is,

[tex]\frac{14 / 3}{7 / 3}=\frac{14}{3} \frac{3}{7}[/tex]

      =2

Carl's mistake is thinking that his quotient (2) is equal to the value of the terms involved in it. In fact, 2 is just a multiplier for 7/3 and doesn't have any specific value associated with it.

Hence, this is the quotient in this Carl multiplies the both value instead of dividing so that is the mistake that made by Carl.
