ANSWER

Option A

EXPLANATION

When a circle has it's center at (h,k) and and radius r units, then its equation in standard form is

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

The given circle has its center at (6,-1) and its radius is r=4 units.

We plug in these values to get

[tex]{(x - 6)}^{2} + {(y - - 1)}^{2} = {4}^{2} [/tex]

[tex]{(x - 6)}^{2} + {(y + 1)}^{2} =16[/tex]

We now expand to obtain

[tex] {x}^{2} - 12x + 36 + {y}^{2} + 2y + 1 = 16[/tex]

[tex] {x}^{2} + {y}^{2} - 12x +2 y + 36 + 1 - 16 = 0[/tex]

[tex]{x}^{2} + {y}^{2} - 12x +2 y + 21 = 0[/tex]

The correct option is 10....

Step-by-step explanation:

The formula of circumference of the circle is:

C = 2πr

where C is the circumference of the circle

r = radius

In this question we have given the circumference and we have to find out the radius:

Thus substitute the values in the formula:

C = 2πr

20π= 2πr

Move 2π to the L.H.S.

20π/2π = r

Cancel out π by π and 20/2 by the table of 2

Therefore we have:

10=r

Thus the correct option is 10....

Final answer:

The measure of the other angle that is complementary to a 13º angle is 77º.

Explanation:

If two angles are complementary, it means they add up to 90 degrees. In this case, one angle is given as 13º. To find the measure of the other angle, we subtract the given angle from 90º because complementary angles sum up to 90 degrees.

So, if we let x represent the measure of the other angle, the equation becomes:

13° + x = 90°

To find x, we subtract 13 from both sides:

The calculation would be:

90º - 13º = 77º.

Therefore, the measure of the other angle is 77º.

Hence, the correct answer is:

Answer:

10u+t=18+10t+u

(If this doesn't match one of the equations, please post your options so I can put it in the form of one of your options.)

Step-by-step explanation:

Let there be a number [tu] where t is the tens and u is ones digit.

t+u=16.

Now we reverse the number [ut] is 8 more than [tu].

[ut]=18+[tu]

So [ut]=10u+t because u is the tens  and t is the ones digit

and [tu]=10t+u because t is the tens and u is the ones digit.

The equation you are looking for is

10u+t=18+10t+u.

Let's solve it just for fun:

Subtract u on both sids:

9u+t=18+10t

Subtract 10t on both sides:

9u-9t=18

Divide both sides by 9:

u-t=2

The system is:

u-t=2

u+t=16

--------------add!

2u  =18

u=9

If u=9 and u+t=16, then t=7.

395.2

Step-by-step explanation:

Area of a trapezoid is:

A = ½ (a + b) h

where a and b are the top and bottom lengths and h is the height.

If 7.6 refers to the entire side length, then the area is:

A = ½ (2.6 + 7.6) (4)

A = 20.4

If 7.6 refers only to the length right of the right angle, we can use Pythagorean theorem to find the length on the left:

x² + 4² = 5²

x = 3

So the whole side length is 3 + 7.6 = 10.6.  That means the area is:

A = ½ (2.6 + 10.6) (4)

A = 26.4

Final answer:

To solve the equations using substitution, isolate y from the first equation, substitute it into the second, solve for x, and then use the value of x to find y. The solution to the system is x = -1 and y = -5.

Explanation:

To solve the system of equations by substitution, we will first isolate y in one of the equations and then substitute it into the other equation.

Step 1: Isolate y in the first equation.

We have y = 3x - 2. This equation is already solved for y, so we can use it as our substitution.

Step 2: Substitute y into the second equation.

Our second equation is x - y = 4. We substitute y with 3x - 2 to get x - (3x - 2) = 4.

Step 3: Solve for x.

Now, we simplify and solve for x:

x - 3x + 2 = 4

-2x + 2 = 4

-2x = 4 - 2

-2x = 2

x = -1

Step 4: Substitute x back into the first equation to solve for y.

Using x = -1 in the first equation y = 3x - 2, we get:

y = 3(-1) - 2

y = -3 - 2

y = -5

Therefore, the solution to the system of equations is x = -1 and y = -5.

Answer:

So (L,W) possibilities are:

(1,4),(4,1),(2,3),(3,2)

That makes 4 possibilities.

Step-by-step explanation:

The perimeter of a rectangle is P=2L+2W where L is the length and W is the width.

We have that P=10, so 10=2L+2W.

10=2L+2W

10=2(L+W)  By factoring using the distributive property.

2(5)=2(L+W)  I factored 10 as 2(5).

If 2(5)=2(L+W), then 5=L+W.

Whole numbers are {0,1,2,3,4,5,6,7,8,9,10,...}. They are your counting numbers and 0.

I think they want natural numbers {1,2,3,4,...}.  This is also just called the counting numbers. The reason I think they want this because if one of the dimensions is 0, we won't actually have a rectangle.

So now looking for numbers from this set that satisfy: L+W=5.

L+W=5

1+4=5

4+1=5

2+3=5

3+2=5

So (L,W) possibilities are:

Final answer:

The equation of the line through (7, -4) and (-1, 3) has a slope of -7/8. It can be written in a point-slope form as y + 4 = -7/8(x - 7), and in slope-intercept form as y = -7/8x + 25/8.

Explanation:

To write the equation of the line that passes through the points (7, –4) and (–1, 3), the first step is to find the slope of the line. The slope (m) is given by the rise over run, which is the change in y divided by the change in x:

Now that we have the slope, we can use the point-slope form which is given by the formula:

We can choose one of the points for x1 and y1; let's use (7, -4):

Therefore, the point-slope form of the line is:

Now, to convert this into the slope-intercept form (y = mx + b), we just solve for y:

After simplifying the constant term:

The slope-intercept form is y = -7/8x + 25/8, where -7/8 is the slope and 25/8 is the y-intercept.

I will split it up for us

y*y= y^2

-3*y= -3y. \

y*-4= -4y. / -7y

-3*-4= 12

y^2+12-7y

The product of (y-3)(y-4), is y^2 - 7y + 12.

To find the product of (y-3)(y-4), we will use the FOIL method, which stands for First, Outer, Inner, Last. This method is used to multiply two binomials.

First: Multiply the first terms of each binomial: y × y = y^2.

Outer: Multiply the outer terms: y × -4 = -4y.

Inner: Multiply the inner terms: -3 × y = -3y.

Last: Multiply the last terms of each binomial: -3 × -4 = 12.

Adding these products together, we get: y^2 - 4y - 3y + 12. Simplifying by combining like terms, the final product is: y^2 - 7y + 12.
