Step-by-step explanation:
f(1)= 64+6(1)
=64+6
=70.
thus, f(1) = 70
f(n)=f(n-1)+?
1=(1-1)+70
1=0+70
=70-1
=69
Just incase u need the work. Its C.
Area of entire circle = (pi)(r^2) and r = d/2:
<span>A =(3.142)((3.2^2) = 32.17m^2 </span>
<span>Portion of circle in sector: </span>
<span>185degrees/360degrees = 0.514 </span>
<span>Multiply: </span>
<span>0.514(32.17m^2) = 16.5m^2 to 1 dp </span>
<span>a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

Answer:
length of the legs is 
Step-by-step explanation:
the both sides of the length of the legs of a right triangle are equal
So it form a isosceles triangle 45- 45- 90 degree triangle
the ratio of 45-45-90 degree triangle is 
xsqrt(2) is the side opposite to 90 degree
so 

Divide both sides by square root (2)

multiply square root (2) at the top and bottom


length of the legs is
