Answer:x=7
Step-by-step explanation:
Here AD=6
AB=6 (tangents drawn from external point to a circle are equal)
Then BC=13-6=7
Now, CE=BC=7(tangents drawn from external point to a circle are equal)
EF=14-7=7
EF=FG=x=7(tangents drawn from external point to a circle are equal)
Answer:
I do not know the equations given but here's my equation and solution:
9x = 174°
x = 19 1/9°
Step-by-step explanation:
(3x + 2) + 2(3x + 2) = 180°
3x + 2 + 6x + 4 = 180°
9x + 6 = 180°
9x = 174°
x = 19 1/9

y-4=3(x-0)
y-4=3x
y=3x+4
Answer:
739.47
Step-by-step explanation:
height - h, radius -r
V=hπ²r=5×3.14²×15=739.47
F(t) = (t^-1) - t
Taking derivative:
<span>f'(t) = d/dt(t^-1) - t) = d/dt(t^-1) - d/dt(t) </span>
<span>f'(t) = -1(t^-2) -1
= -t^-2 - 1 </span>
<span>f'(t) = v(t),
It can be also written as :
-1/t^2 - 1 </span>
<span>So v(3) = -1/(3^2) - 1 = -1/9 - 1 = -10/9</span>
