An ellipse is drawn with major and minor axes of lengths 10 and 8 respectively. using one focus as a center, a circle is drawn that is tangent to the ellipse, with no part of the circle being outside the ellipse. compute the radius of the circle.

  2

Step-by-step explanation:

The distance between foci is the root of the difference of the squares of the axes lengths:

  d = √(10² -8²) = √36 = 6

Then the radius of the circle is half the difference between this and the length of the major axis:

  r = (10 -6)/2 = 4/2

  r = 2

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
