Answer:
EZ PZ bruh
Step-by-step explanation:
First one, -25/4 ÷ -5 5/4
change the second mixed fraction into an improper one
=> -25/4 ÷ -25/4; dividing a number by itself gives you '1'
=> 1
second question,
=> -3/21 × -3; multiply the numerator with the other numerator, and since there is nothing given in the denominator of the second number mean its 1, hence multiply the denominator with the other denominator, and we get:
=> 9/21; we simplify this fraction and get: 3/7

Answer:
Option 1:(x-4)^2+y^2=100
Step-by-step explanation:
Given center = (h,k) = (4,0)
The point (-2,8) lies on circle which means the distance between the point and center will be equal to the radius.
So,
The distance formula will be used:
Hence radius is 10.
The standard form of equation of circle is:
(x-h)^2+(y-k)^2 = r^2
Putting the values
(x-4)^2+(y-0)^2=10^2
(x-4)^2+y^2=100
Hence option 1 is correct ..
