Answer:
137.24 mm²
Step-by-step explanation:
Big square = 9x9=81
Small rectangle at bottom = 2x3=6
Quarter Circle = 1/4(3.14)(8)(8)=50.24
81+6+50.24=137.24
1)=1 mechanical energy
2)=2 kinetic energy
3)=9 nuclear energy
4)=7 sound energy
5)=6 thermal energy
6)=4 electrical energy
7)=8 chemical energy
8)=3 potential energy
9)=10 energy conversions
10)=5 light energy
Answer:
14
Step-by-step explanation:
Sin(∅) = Opposite angle ÷ hypotenuse.
Sin (45) = 7
÷ hypotenuse
hypotenuse = 7
÷ sin(45)
*********************
Keep in mind
sin(45) = √2÷2
*********************
so we have: Hypotenuse = 7√2 ÷ (√2÷2)
Hypotenuse= 14.
Answer:
15
Step-by-step explanation:
Note: Take note , absolute value will give the magnitude of the value. (Which means ignoring the + / - signs.)
Eg. | - 19 | = 19
Therefore,

Answer:
Step-by-step explanation:
These are "like terms," as both terms contain √5. We add the coefficients together but leave the radical term √5 as is:
√5
+ 6√5
