Answer:
415.48 or 132.25 pi cm
Step-by-step explanation:
23 divided by 2 is 11.5 so that is the radius. Then you multiply the radius by pi. Or you can do 11.5 x 11.5 if you are trying to find the solution without pi.
Y=x^2-5, solve for x
y+5=x^2
x=√(y+5) so
f^-1(x)=√(y+5)
Answer:
3 1/5 minutes per meter
Step-by-step explanation:
To find the rate in minutes per meter, divide the number of minutes by the number of meters:
(2.4 min)/(0.75 m) = 3.2 min/m = 3 1/5 minutes per meter
With lower case numbers and numerals from 0-9 there are about <u>4,738,381,338,321,616,896 possible passwords.</u>
<u></u>
Add up the number of possible numbers and letters.
There are 26 letters in the alphabet, 0-9 would mean 10 digits. Which is 36.
The length of the password she wants is 12.
36 to the power of 12 = 4738381338321620000
4738381338321620000
4 = 3/4m -6
add 6 to both sides
10 = 3/4m
divide both sides by 3/4
m = 10 / 3/4 = 10 *4 = 40 /3 = 13 1/3
