Answer:
The required equation is 
.
Step-by-step explanation:
If a quadratic equation is 
, then the quadratic formula is
The given quadratic equation is
Here, a=1, b=-9 and c=-20.
Substitute a=1, b=-9 and c=-20 in the above quadratic formula.
Therefore the required equation is .
According to the question requirements
v= 4/3*pi*r^3
dv/dt = 4*pi*r^2*dr/dt
when
d= 1.7
r= 0.85
and
dv/dt = 2
2= 4*pi*(0.85)^2*dr/dtthus the the speed of increasing of the balloon's diameter is
dr/dt = 1/(2pi*(0.85)^2)

Answer:
2nd option
Step-by-step explanation:
Consider the coordinates of T(- 3, 3 ) → T' (3, - 1 )
- 3 → 3 is 6 units right in the positive x-direction
3 → - 1 is 4 units down in the negative y- direction
Then translation rule is
(x, y ) → (x + 6, y - 4 )
Answer:
49.4 degrees
Step-by-step explanation:
SOHCAHTOA
tan x = opposite / adjacent
tan x = 7 / 6
using graphing calculator, you get x = 49.398 round to tenth = 49.4 degrees
