Answer:
Step-by-step explanation:
I realize that the time is passed.... but FYI
BD is <u><em>Geometric Mean</em></u>
That's mean BD² = 6 × 5 = 30 ⇒ BD = √30
x² = BD² + 6² = 30 + 36 = 66 ⇒ x = √66
y = √55
Dividing 40 into fifths...
40 ÷ 5 = 8
Since 1/5 of 40 is 8, 2/5 of 40 is <u>16</u>.
Irrational as 0.75 x 0.75 x 3.14......
Note that the equation of the circle is
(x-h)² +(y-k)² =r²
where centre is (h,k)
the equation of the circle based on the information given
(x-3)² +(y-4)² =r²
and the point on the circle (3,-2)
substitute into the equation
(3-3)² +(-2-4)² =r²
r=6 or r=-6
since r is radius, we reject r=-6 since radius must be nonnegative.
the radius is 6
4^1= 4. the exponential form is b^e=n, while log is logb n=1.
