Answer:
b. 12
Step-by-step explanation:
Answer:
cos3x
Step-by-step explanation:
y" - y' + 9y = 3 sin 3x
here 
will be replaced by 
where 
is coefficient of x
y=cos3x
hence Particular solution is cos3x
Answer:
133m
Step-by-step explanation:
Rate can be defined as the measure of a quantity with time
Rate the professional cyclist travels =380/20
To know the rate rate, in meters will the cyclist travel in 7 seconds then we equate the rate above as
380/20= x/7
Cross multiply
380×7=20X
2660= 20x
X=133m
Hence, the rate rate, in meters will the cyclist travel in 7 seconds is 133m
Answer:
V = 4/3 pi or approximately 4.187 ft^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
The radius is 1 ft
V = 4/3 pi (1)^3
V = 4/3 pi
We can approximate pi by 3.14
V = 4/3 (3.14)
V = 4.186666666 ft^3
Answer:
8x^2 - 2xy + 3y^2
Step-by-step explanation:
Use the FOIL method
8x^2 + 4xy - 6xy + 3y^2
8x^2 - 2xy + 3y^2
