Answer:
Here is the complete question:
For which pair of functions is the exponential consistently growing at a faster rate than the quadratic over the interval 0<=X<=5.
Answer is C (the third option)
Step-by-step explanation:
Basically in exponential growth a quantity may increase over time. When a quantity increases of decreases by equal or same percent over equal period of times this means that the quantity increases or decreases exponentially. I have attached the image of the correct option.
We have that
7x^2 + 4x - 8 = 14-----------------> 7x²+4x-22=0
Step 1
Solving<span> a </span><span>second degree equation
</span>x1=[-b+√(b²-4ac)]/2a
x2=[-b-√(b²-4ac)]/2a
a=7
b=4
c=-22
then
x1=[-4+√(4²-4*7*(-22))]/(2*7)-----------> [-4+√(632)]/(14)
x1=-(-4+25.14)/14=1.51
x2=[-4-√(4²-4*7*(-22))]/(2*7)-----------> [-4-√(632)]/(14)
x2=-(-4-25.14)/14=-2.08
the solutions of the system is
x1=1.51
x2=-2.08

using a graph tool
see the attached figure
the answer is
the numerical expressions is
x1=[-b+√(b²-4ac)]/2a
x2=[-b-√(b²-4ac)]/2a
Answer:
A = 60 cm²
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = lb ( l is length , b is breadth )
Here l = 15 and b = 4 , then
A = 15 × 4 = 60 cm²
Scale Factor = 1:12
It means, for every in in the model, it is equivalent to 12 inches in the real.
Dimensions of the real Car = 132 * 66
So, Dimensions of the model = 132/12 * 66/12 = 11 * 5.5
In short, Your Answer would be: 11 * 5.5 cm
Hope this helps!
