Find all of the points of the form (x, −x) which are 7 units from the origin.

Morgarella [4.7K]

Answer:

(-7, 0) and (7, 0)

Step-by-step explanation:

<u>All the points that are 7 units from the origin are on the circle:</u>

x² + y² = 7²

<u>The maximum and minimum values of x obtained when y = 0:</u>

x² = 7²
√x² = √7²
x = ± 7

So

min x = -7 and
max x = 7

<u>The points are:</u>

(-7, 0) and (7, 0)

6 (2)^2 = 24

a = 24

b = 6

y-intercept: (0,6)

y-intercept =

Step-by-step explanation:

6(2)^x

6 (2)^0 = 6 (a number ^0 = 1, 6 times 1 = 6)

6 (2)^2 = 6 x 4 = 24

What is the circumference of a circle whose radius is 13?

Inessa05 [86]

Answer:

Circumference, C = 81.68 units

Step-by-step explanation:

Given that,

The radius of the circle, r = 13 units

We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :

$C=2\ \pi r$

$C=2\ \pi \times 13$

C = 81.68 units

So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
