" e+7 " means the same thing as " x 10⁷ ".
They both mean "move the decimal point 7 places that way ===> ."
So take the 3.82 and do that to it.
If there aren't enough places to move the decimal point far enough,
then add some zeros onto the end of the 3.82 before you move
the point.
Answer:
3/10
Step-by-step explanation:
u divide the fractions and u got a decimal I change the decimal and got 3 so I changed it to a fraction and got 3/10
Answer:
False
Step-by-step explanation:
2cos^2(4x) - 1 = cos(8x)
cos(8 *pi/12) = cos(2pi/3) = cos(pi - pi/3) = - cos(pi/3)= 1/2, which is not 0
cos(8x) = 0
==> 8x = 0 or pi
==> x = 0 or pi/8
Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
Answer:
The correct option is (c).
Step-by-step explanation:
The combined formula is given by :
...(1)
h is height
V is volume
r is radius
It is clear from formula (1) that h varies directly with V and inverse;y with the square of r.
Hence, the correct option is (c).
