Given that AE is a tangent of the circle with the center at B, BC = 3.5, and AE = 24, which is the length of EC?

1 answer:

5 0

We are actually given here a right triangle where EC is the hypotenuse. The length of one side is AE = 24, and the other side AC is simply twice BC, so AC = 7:

EC^2 = AE^2 + AC^2

EC^2 = 24^2 + 7^2

EC = 25

Answer:

The slope = 3/4

Step-by-step explanation:

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$m=\frac{6-3}{2-(-2)}=\frac{6-3}{2+2}$

m = 3/4

Arturiano [62]

Answer:

1,757,600,000

Step-by-step explanation:

company consists of 3 letters followed by 5 numbers how many different account numbers are possible if repetitions of letters and digits are allowed.

We have 26 lettrs and 10 digits

So, the possible out comes for each one of the letters = 26

And the possible out comes for each one of the numbers = 10

∵ repetitions of letters and digits are allowed.

So, the possible accounts are = 26³ * 10⁵ = <u>1,757,600,000</u>
