(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
No, 4/5 does not equal to 5/10.
Because:- When you try to see if it is proportional, it does not equal it.
4/5 ≠ 5/10
Simplify to make sure.
4/5 ≠ 1/2
4/5 is NOT equal to 1/2.
Therefore, our final answer is that 4/5 does not equal 5/10.
Answer:
or ≈6.59
Step-by-step explanation:
We can first begin by simplifying each of the numbers with exponents. Recall that in a fraction exponent, the numerator is the power, while the denominator is the root.
Take 
for example. The '2' in the fraction means we must take the square of 25. √25 = 5.
The '3' in the fraction means we take the power, which means we must cube '5'.
5³ = 125. Therefore, = 125. Use this process for the other numbers:
The new fraction would look like:
Which simplifies to:
or ≈6.59

Answer:
sqrt(2) ≈1.414213562
Step-by-step explanation:
Distance is found by the formula
d =sqrt ( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (-1/8 - 7/8)^2 + (7/8 --1/8)^2)
sqrt( (-8/8)^2 + (7/8 +1/8)^2)
sqrt( (-1)^2 + (1)^2)
sqrt ( 1 +1)
sqrt(2)
