The standard form of the equation of circle is:
(x – h)^2 + (y – k) ^2 = r^2
Where the center being at the point (h, k) and the radius
being r
Substituting the values to the equation:
<span>(-15 - (-7)) ^2 + (y – (-1)) ^2 = 13^2 </span>
64 + (y +1) ^2 = 169
(y +1) ^2 = 105
y + 1 = 10.247
<span>y = 9.247</span>
We will be using the fact that , where is the probability that the first bulb works and is the probability that the second bulb works.
The probability that the first bulb works is . However, when we take one out (given that the first bulb works) we now have 19 working bulbs and 4 bad ones. This means that the probability that the second bulb works is .
Now, we can find our final probability:
Answer:
942 square cm
Step-by-step explanation:
10(n-6)
10n-60
n = 14 so we plugged in
10.14-60
140-60
80 is final value
Some of the math terms are originated from the Latin language.
From these terms are "unit" which actually means one of something and also "plus" which means many things added together.
Other terms of Maths are generated from Greek language as "ply" which means many and "nomial" which means term.
