The value of a particular rookie baseball card was $2.00 when it was first printed. Five years later, when the player was at his

mash [69]

Let t be the time passed in years and y be the value of baseball card.

You know that

when x=0, then y=2;
when x=5, then y=25;
when x=10, y=8.

The equation in standard form is $y=ax^2+bx+c.$ Substitute given data into the equation:

$a\cdot 0^2+b\cdot 0+c=2,\\\\a\cdot 5^2+b\cdot 5+c=25,\\\\a\cdot 10^2+b\cdot 10+c=8.$

Solve the system of equations:

$\left\{\begin{array}{l}c=2\\25a+5b+c=25\\100a+10b+c=8\end{array}\right.\Rightarrow \left\{\begin{array}{l}c=2\\25a+5b=23\\100a+10b=6\end{array}\right.\Rightarrow$

$\left\{\begin{array}{l}c=2\\a=-0.76\approx -0.8\\b=8.4\end{array}\right.$

Then the parabola equation is

$y=-0.8x^2+8.4x+2.$

Simplify each of the following powers of i. i^99=

Scorpion4ik [409]

I= sqrt (-1)

If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i

99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd

Now check (99+1)/2= 100/2= 50,
50 is even so
i^99 = -i

Given limit of f (x) = negative 4 as x approaches c and limit of g (x) = one-fifth as x approaches c. what is limit of left-brac

sergey [27]

Since the limit of f(x) is non-zero, the limit distributes over the quotient and

$\displaystyle \lim_{x\to c} \frac{g(x)}{f(x)} = \frac{\displaystyle \lim_{x\to c}g(x)}{\displaystyle \lim_{x\to c}f(x)} = \frac{\dfrac15}{-4} = \boxed{-\frac1{20}}$
