Given :
The value of the surface area of the cylinder is equal to the value of the volume of the cylinder.
To Find :
The relation between height and radius.
Solution :


Now ,

Hence, this is the required solution.
15 hrs a week at 8.95 per hr = (15 * 8.95) = 134.25 gross pay
FICA (7.65%)....0.0765(134.25) = 10.27
fed.tax (9.3%)...0.093(134.25) = 12.49
state tax (5.8%)..0.058(134.25) = 7.79
total taxes : 10.27 + 12.49 + 7.79 = 30.55
savings account money = 30
134.25 - (30.55 + 30) =
134.25 - 60.55 = 73.70...its gonna be the last one because I did a little rounding up above
Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5
thus,
x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2
The answer is option C
Steps of construction:
1. Draw a circle with centre B.
2. Draw a circle with centre C.
3. Both circles intersect each other at a point D
4. Join A and D.
5. So, AD bisects angle CAB.
<em>A </em><em>rough </em><em>figure </em><em>is </em><em>shown</em><em> </em><em>in </em><em>the </em><em>picture</em><em>.</em>
4k^2=5k
4k^2-5k=0
k(4k-5)=0
4k-5=0 => x2=5/4=1.25
k=1.25
