(x-h)²+(y-k)²=r² is the equation of a circle with radius of r
so if x-h=4 and y-k=3 then
4²+3²=r²
16+9=r²
25=r²
sqrt both sides
5=r
radius is 5 units
Answer:
33.3 Repeating
Step-by-step explanation:
1. You already know that 33 is the whole number so you have 33.
2. 1/3 is converted to .3333333 so you put 33 before the decimal point
3. You get 33.3333333
Hope this helps :)
Answer:
According to logarithmic properties.... The right hand side can be written as
log base 7 (180/3).....which is log base 7 60
So according to the question cancel out the log base 7 from both sides....
Then we get 8r + 20 = 60
That is 8r = 40..
That is r = 5......
Therefore the value of r is 5
-1 = 3x - 7
Add +7 to each side
6 = 3x
Divide each side by 3
X = 2
f(-1) = 3 * 2 - 7
