Answer:

49π

Step-by-step explanation:

πr^2   <---- The formula for the area of a circle.

let "a" represent area of the circle.

a = π × 7^2

Simplify by the use of the exponent.

7^2 = 49

Your answer:

49π

We are asked to find the reference angle for a standard angle of 334°

Recall that the reference angle is the angle that is measured with respect to the x-axis.

First, we need to find out in which quadrant the given standard angle lies.

334° lie in the 4th quadrant (180° to 360°)

So, the reference angle can be found as

Therefore, the reference angle is 26°

If the new line passes through the point (-6, 2), let's use x = -6 and y = 2 in the equation and then solve it for 'a':

Therefore the value of 'a' is 5.

The perimeter of a rectangle is given by:

P = 2w + 2h

Where:

w = width = 2x

h = height = x

P = 18

Replacing the data into the equation:

18 = 2(2x) + 2(x)

18 = 4x + 2x

18 = 6x

Solving for x:

x = 18/6

x= 3

Therefore:

w = 2(3) = 6m

h = 3m

---------------------------------------------------------------------------------

P = x + 2x + (x + 3)

23 = 3x + x + 3

23 = 4x + 3

Solving for x:

23 - 3 = 4x

20 = 4x

20/4 = x

5 = x

Therefore its sides are:

x = 5 ft

2x = 2(5) = 10ft

x + 3 = 5 + 3 = 8ft

The two European nations took control of the regions in the Middle East that had been controlled by the Ottoman Empire are Britain and France.

The Ottoman Empire had long held the top position among Islamic nations in terms of geography, culture, and theology. Due to the division of the Ottoman Empire after the war, Western powers like Britain and France came to dominate the Middle East, and the modern Arab world and the Republic of Turkey were established.

The Turkish National Movement initiated opposition to these forces, but it did not extend to the other post-Ottoman states until the time of quick decolonization following World War II.

The equation of a circle whose center is (a, b) and which has a radius r is given as:

(x - a)² + (y - b)² = r²

For the circle with endpoints at A(-2,3) and B(4,5).​

The center (a, b) of the circle is calculated as:

The center, (a, b) = (1, 4)

The diameter(D) of the circle is the distance between the endpoints A(-2,3) and B(4,5).​

The diameter of the circle = √40

Radius = Diameter / 2

r = d/2

r = √40 / 2

Substituting a = 1, b = 4, and r = √40 / 2 into the general equation of a circle:

The general equation of the circle is:

We are given the following equation.

we are asked to find an equation for "t". To do that, we are going to solve for "t", first by subtracting "p" on both sides, like this:

Now we will divide both sides of the equation by "pr"

A thus we found a relationship for "t".

The answer is C

x = 1, y = 3

The given system of equations is:

y = 4x - 1.......................(i)

y - 2x = 1..................(ii)

Substitute equation (i) into equation (ii)

4x - 1 - 2x = 1

4x - 2x = 1 + 1

2x = 2

x = 2/2

x = 1

Substitute x = 1 into equation (i)

y = 4x - 1

y = 4(1) - 1

y = 4 - 1

y = 3

The solution to the system of equations is x = 1, y = 3

Answer:

u = -2

Explanation:

Given the expression;

7 - 6u = 5u + 29

We are to find the value of u;

Collect like terms;

-6u - 5u = 29 - 7

-11u = 22

Divide both sides by -11;

-11u/-11 = 22/-11

u = -2

Hence the value of u is -2

The solution of u in the equation is,

⇒ u = -2

Given that;

the expression is,

⇒ 7 - 6u = 5u + 29

Now, We have to find the value of u;

⇒ 7 - 6u = 5u + 29

Combine like terms;

⇒ -6u - 5u = 29 - 7

⇒ -11u = 22

Divide both sides by -11;

⇒ -11u/-11 = 22/-11

⇒ u = -2

Therefore, the value of u is -2.

According to the given data we have the following equation:

6x+y=12

To rewrite the following equation in slope-intercept form we would have to make the following steps:

6x+y=12

Move 6x to the other side, by doing this it would change its sign

So,

y=-6x + 12

So, equation in slope-intercept form would be y=-6x + 12

We have this number and we have to sort them from least to greatest.

We start by expressing them in decimals in order to compare them easily.

Take into account some of them are irrational, so they will be expressed approximately by a decimal (for example, pi).

Then, we have:

The least will be the negative numbers of this group, so we start with the negative value with the most absolute value: -3.27.

Then, we continue with -2.

Then, we start with the positive values: 3.07, pi, 13/4, sqrt(12) and 22/2.

Then, we can write them in order as:
