Answer:
3,14
Step-by-step explanation:
3x+5=6x-4
x=3
y=3x3+5
y=14
x,y=3,14
14=3x3+5
14=6x3-4
14=14
14=14
(x,y)=3,14
Answer:
Step-by-step explanation:
You know how Soh Cah Toa applies to right triangles; you can assign the adjacent side = 4 and hypotenuse = 7
CosФ = (adjacent) / (hypotenuse)
Then with the Pythagorean theorem
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
b = √(33)
So "b" is the opposite side.
SinФ = (opposite) / (hypotenuse) = √(33)/7
TanФ = (opposite) / (adjacent) = √(33)/4
The population of the bacteria 96 minutes from now is 12.
Answer:
.31 g / mL
Step-by-step explanation:
Density = mass / volume
Sample 3
mass = 7 1/4 = 7.25
Volume 23.1
Density = 7.25/ 23.1 = .313852814
To the nearest hundredth
.31 g / mL
