Answer:

D. EF and GH

Step-by-step explanation:

Common internal tangent : A tangent of two circles is called a common internal tangent when the tangent intersects the line segment joining the center of the circles.

Here, AB, CD, GH and EF are tangent lines of the circles,

But, the intersection of AB and line joining the center as well as the intersection of CD and line joining the center is emptied,

Hence, Option A, B, C can not be correct.

Also, both tangent lines EF and GH can intersect the line segment joining the center of the circles.

Hence, Option 'D' correct

Check the picture below, those red ones

internal tangents are the ones touching both circles and in between

find the difference between the sum of all eight positive intergral divisors of 66 and the sum of all eight positive integral di

katrin [286]

The difference between the sum of all eight positive integral divisors of 66 and the sum of all eight positive integral divisors of 70 is zero.

<h3>How to find the difference between the integral divisors?</h3>

First let's find the integral divisors. We can write 66 as a product of prime numbers as:

66 = 33*2 = 2*3*11

Then the integral divisors of 66 are:

2*3 = 6

2*11 = 22

3*11 = 33

1 (trivially)

66 (trivially)

The sum gives:

2 + 3 + 11 + 6 + 22 +33 + 1 + 66 = 144

For 70 we have:

70 = 7*10 = 2*5*7

Then the integral divisors are:

2*5 = 10

2*7 = 14

5*7 = 35

The sum gives:

1 + 70 + 2 +5 + 7 + 10 + 14 + 35 = 144

Then the difference between these two sums is:

144 - 144 = 0

What's -8.2 x 10 to the fifth power? Please explain your answer. Thank you!

Stolb23 [73]

First lets find -8.2 x 10 = -82 know we find 82^5 which is 82*82*82*82*82

-82*-82=6724 and then 6724*-82= -551368 and then -551368*-82 =45212176 and then 45212176*-82= -3707398432 and finally -3707398432 is our answer i checked the calc to after i did the hard math that took me forever i had some help from the calc and i got this hopefully this helps

The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is , where l represents t

Gekata [30.6K]

Answer:

A. 7 in.

Step-by-step explanation:

We have been given that the perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is , where l represents the length of the rectangle and w represents the width of the rectangle.

We know that perimeter of rectangle is 2 times the sum of width and length of rectangle.

$\text{Perimeter}=2(l+w)$

$\text{16 in}=2(l+w)$

$\frac{\text{16 in}}{2}=\frac{2(l+w)}{2}$

$\text{8 in}=l+w$

To be a rectangle length cannot be 8 as length and width of the rectangle is 8 inches.

Therefore, 7 inches the possible value for the length of the rectangle.

If A: B = 5:7 and B: C = 3: 5, then A :B: C is:

mel-nik [20]

Answer:

15:21:35

Step-by-step explanation:

to find this answer you must find a ratio in which both bs are the same

multiple a:b by 3 and b:c by 7

15:21 21:35

then you can put the bs together

15:21:35

that is your answer

Determine the intervals on which the function is increasing, decreasing, and constant

max2010maxim [7]

I believe it's increasing on all fronts, because if you start from the right, you see that the y values always increase, hence they are increasing. They do it for when x<0 and when x>0. So, it should be increasing on all real numbers
