Answer:
Option A
Step-by-step explanation:
The standard form of an equation of a circle is represented by the formula 
. Remember that 
is the center and 
is the radius squared.
So, the equation of the circle must be 
. Complete the square to change the form of the equations listed in the options and find the one that is equal.
Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:
The end result matches with the equation determined before, so option A is the answer.
This is truly a simple, one-step equation if looked at in the right angle.
You're going to want to multiply 115 by .952:
115
<u> x .952
</u> 230
+ 6050
<u>+ 93500
</u> 109.48
$109.48 is your final answer.
Answer:
-2
Step-by-step explanation:
Put the given value in the equation and solve for x.
f(x) = 12
f(x) = 2(x +8)
12 = 2(x +8) . . . . . use 12 for f(x)
6 = x +8 . . . . . . . . divide by 2
-2 = x . . . . . . . . . . subtract 8
Answer:
b. 9/50
Step-by-step explanation:
•the probability of the selected flight arriving on time: 820/1000 = 0.82
•find the probability of the flights not being selected by subtracting 0.82 from 1.00: 1.00-0.82=0.18
•now you look for the answer that equals to 0.18
50/1 =50 nope
9/50 =0.18 yes
41/50 =0.82 nope
1/4 = 0.25 nope
