92
given 2a² + 5b²
substitute given values for a and b into the expression
2(- 6)² + 5(2)² = (2 × 36 ) + (5 × 4) = 72 + 20 = 92
Answer:
x = 13
Step-by-step explanation:
First start with the blank equation

Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.

Then solve
25 + 144 = 
169 =

c = 13
Answer:
88 Inches
Step-by-step explanation:
For any bicycle tire of a given diameter, the approximate distance moved by the bicycle each time the wheel goes around is determined by the circumference of the circular wheel.
Since the diameter =28 Inches
Circumference =
The bicycle moves 88 Inches forward each time the wheel goes around.
Answer:
0
Step-by-step explanation:
Plug in 11 for m. Remember to follow PEMDAS. First solve the parenthesis, then multiply.
m = 11
7(m - 11) = 7(11 - 11) = 7(0) = 0
0 is your answer.

Answer:
Required largest volume is 0.407114 unit.
Step-by-step explanation:
Given surface area of a right circular cone of radious r and height h is,
and volume,

To find the largest volume if the surface area is S=8 (say), then applying Lagranges multipliers,
subject to,

We know for maximum volume
. So let
be the Lagranges multipliers be such that,



And,



Substitute (3) in (2) we get,



Substitute this value in (1) we get,



Then,

Hence largest volume,
