Answer:

The solution of given equation is (2,5)

Step-by-step explanation:

The equations give to us are:

y - 3 = x

or

y = x + 3

y = x² - 6x + 13

We can find the solution of the given system of equations by substituting each point in both of the equations. The point which satisfies both of the equation will be the solution of the the system of given equation.

Substitute (2,5) in both equations

y = x+3

5 = 2+3

5 = 5

TRUE

y = x² - 6x + 13

5 = 2² -6(2) + 13

5 = 5

TRUE

Similarly, we can also check the rest of the points, which come as FALSE.

Therefore, the solution of given equation is (2,5)

if i want the track to have a circumference of 400 feet what does the diameter of the track need to be?
natta225 [31]

Answer:

The diameter of the track needs to be 127.27 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- The circumference of any circle is C = 2πr, where r is the radius

  of the circle and π is the constant ratio between the

  circumference and the diameter of the circle which

  approximately is 22/7 or 3.14

- The diameter of any circle is twice its radius

* <u><em>Lets solve the problem</em></u>

- The circumference of the track is 400 feet

∵ The circumference = 2πr

∵ π = 22/7

∴ 400 = 2 × 22/7 × r

∴ 400 = 44/7 r

- Divide both sides by 44/7 to find r

∴ r = 63.63

∵ The diameter of the circle = 2r

∵ The radius = 63.63 feet

∴ The diameter = 63.63 × 2 = 127.27 feet

* The diameter of the track needs to be 127.27 feet

Answer:

  $3277.23

Step-by-step explanation:

The future value of the CD with interest at rate r compounded semiannually for t years will be given by ...

  A = P(1 +r/2)^(2t)

where P is the principal value.

For the given rate and time, this is ...

  A = $2000(1 +0.05/2)^(2·10) = $2000(1.025^20) ≈ $3277.23

The value of the CD at maturity will be $3277.23.

Choose all of the transformations that would change a triangle into one that is similar, but not congruent. Which transformation
Vsevolod [243]

You didn't supply a list.  The so-called rigid transformations of translation, rotation and reflection create congruent triangles.

Generally it's dilation by a factor about a point is preserves similarity but not congruency.  Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
