k = 13 is the value of k in quartic equation.
What does the term "quartic equation" mean?
An equation of the fourth degree, often known as a quartic equation, is one that reduces a quartic polynomial to zero. in which a 0. A quartic function's derivative is a cubic function.
Let α = 7x
β = 6x
α + β = 7x + 6x = k/3 ............1
13x = k/3
αβ = 7x × 6x = 14/3
42x² = 14/3
x² = 14/3 × 42
x² = 1/9
x = 1/3
now putting value of x in 1
7/3 + 6/3 = k/3
1/3( 7 + 6 )= k/3
k = 13

Answer:
Approximately 149 cubic centimeters of water
Step-by-step explanation:
step 1
Find the volume of water in the tank
The volume of a rectangular prism is equal to
we have
substitute
step 2
Find the volume of the cylindrical container
The volume of the cylinder is equal to
we have
---> the radius is half the diameter
substitute
step 3
To find out how much water is still in the tank, subtract the volume of 10 containers of water from the volume of the tank
so
therefore
Approximately 149 cubic centimeters of water
Answer:
Mikhail is 50 years old.
Step-by-step explanation:
Let m represent how old Mikhail is.
110 = (m + 10) + m
Combine equal variables.
110 = 2m + 10
Get the variable alone by cancelling out the 10.
110 - 10 = 2m
Simplify.
100 = 2m
Divide.
m = 50
