Answer:
7.6 for delta math trust me
Step-by-step explanation:
The standard form for the equation of a circle is :
<span><span> (x−h)^2</span>+<span>(y−k)^2</span>=r2</span><span> ----------- EQ(1)
</span> where handk are the x and y coordinates of the center of the circle and r<span> is the radius.
</span> The center of the circle is the midpoint of the diameter.
So the midpoint of the diameter with endpoints at (2,-5)and(8,-9) is :
((2+(8))/2,(-5+(-9))/2)=(5,-7)
So the point (5,-7) is the center of the circle.
Now, use the distance formula to find the radius of the circle:
r^2=(2−(5))^2+(-5−(-7))^2=9+4=13
⇒r=√13
Subtituting h=5, k=-7 and r=√13 into EQ(1) gives :
(x-5)^2+(y+7)^2=13
Answer:
21
Step-by-step explanation:
You need to use the rule that they gave you (1.5t+3). Since t represents the time in weeks, replace t with 12. Now multiply. 1.5x12=18. 18+3=21
Answer:
finance charge refund is $91.53
Step-by-step explanation:
given data
finance charge F = $476
time t = 12 month
no of payment n = 5
to find out
finance charge refund
solution
we will apply here finance charge refund formula that is
finance charge refund = F × 
put here value we get
finance charge refund = 476 × 
finance charge refund = 476 × 
finance charge refund = 476 × 
finance charge refund = 476 × 0.1923
finance charge refund = 91.53
so finance charge refund is $91.53
Think of it like this, if there are 13 cards numbered 1-13 and you need to find the probability of pulling a multiple of 3.
Then start by laying out all your options.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
Then find all of the multiples of 3
3, 6, 9, 12
There are 4 multiples of 3 out of all of the cards so you have a 4 out of 13 chance to pull a card with a multiple of 3 on it.
Answer = 4/13
