Answer:
The answer is 7.2368421053 .
Option C
The solution of equation x^2+3x+4=0 is x= -3+- square root of -7/ 2
Solution: Need to identify correct option for solution of the equation x^2 + 3x + 4 = 0.
Given equation is quadratic equation. We can find solution of this equation using quadratic formula.
According to quadratic formula for general equation solution of the equation is given by
The given equation is So in our case, a = 1, b = 3 and c = 4
On applying quadratic formula we get
As i is square root of -1,
Hence correct option is C that is roots of quadratic equation
Step-by-step explanation: Tell me if i'm wrong

formula used to calculate shear stresses due to bending, τ = VQ/It. We have just read the internal shear force, V, off of the shear diagram. We also already calculated the moment of inertia for this particular section.
τ=6000N
Answer:
it would be 2x-6
Step-by-step explanation:
since you don't know what the value of "the number" is you would put a variable, x. and there is 2 of this number.
then 6 less would be -6 of this variable.
One rotation is equivalent to the circumference of the tire. In other words, if the tire makes one complete rotation and the bicycle has traveled a distance equal to the circumference of the tire.
Solution:
C = 3.1416 which is the pi (d)
C = 3.1416 (27)
C = 84.82
The circumference is about 84.82 inches. To find the distance the bicycle will travel in 10 rotations then multiply the circumference by 10.
84.8 (10) = 848.2
So, the bicycle will travel about 848.2 inches in 10 rotations.
