Answer:
x=3.414 and x=0.59 is the desired answer.
Step-by-step explanation:
We are given a quadratic equation as : 
on dividing both side by 2 we have the equation as
on solving for the roots of the equation using the quadratic formula we get that 
and 
x=2+1.414 and x=2-1.414
Hence , x=3.414 and x=0.586≈0.59.
The sub dives 37 feet....thats -37...it rises 16 ft....-37 + 16 = -21...then dives 18 ft.....-21 - 18 = - 39 ft
so the net change is -39 ft
Answer:
L=80
W=20
Step-by-step explanation:
Perimeter = 2×L+2×w
L=w+60
Perimeter - 2×60 = 4×w
200-120 = 80
80/4= w = 20
L=w+60 = 80
The volume of the cylinder in terms of π is 18,095.5736 square yards,
the volume of the cylinder by using π equals 3.14 is 18.086.4 square yards.
Step-by-step explanation:
Step 1; The volume of any cylinder is given by π times the product of the square of the radius (r²) and the height (h). The given cylinder has a radius of 12 yards and a height of 40 yards.
The volume of any cylinder = π × r² × h.
Step 2; The value of π equals 3.14159263588. So substituting this value in the equation to calculate the volume we get
The volume of the given cylinder = 3.14159263588 × 12² × 40 = 18,095.5736 square yards.
Step 3; If we substitute the value of π as 3.14 in the equation to calculate the volume, we get
The volume of the given cylinder = 3.14 × 12² × 40 = 18.086.4 square yards.
20-10=10 therefore X=10
10+10=20
