Answer:

Given a function y=f(x) its first derivative – the rate of change of y with respect to x – is defined by: dydx=limh→0[f(x+h)−f(x)h]. Finding the derivative of a function by computing this limit is known as differentiation from first principles

Answer:

see explanation

Step-by-step explanation:

Given f(x) then the derivative f'(x) is

f'(x) = lim( h tends to 0 ) \frac{f(x+h)-f(x)}{h}

      = lim( h to 0 ) \frac{\frac{3}{x+h}-\frac{3}{x}  }{h}

     = lim( h to 0 ) \frac{3x-3(x+h)}{hx(x+h)}

     = ( lim h to 0 ) \frac{3x-3x-3h}{hx(x+h)}

     = lim( h to 0 ) \frac{-3h}{hx(x+h)} ← cancel h on numerator/ denominator

     = lim( h to 0 ) \frac{-3}{x(x+h)} ← let h go to zero, then

f'(x) = - \frac{3}{x^2}

A man buys a racehorse for $20,000 and enters it in two races. He plans to sell the horse afterward, hoping to make a profit. If
victus00 [196]

Answer:

The expected profit is $10,600.

Step-by-step explanation:

The expected profit can be calculated as the sum of the possible outcomes weighted by their probability of occurrence.

In this case, there are four possible outcomes:

1) The horse win both races. The value of the horse will be $100k-$20k=$80k.

The probability of this outcome is:

P(ww)=P(w1)*P(w2)=0.2*0.3=0.06

2) The horse win the first race, but lose the second one. The value will be $50k-$20k=$30k.

The probability is:

P(wl)=P(w1)*(1-P(w2))=0.2*(1-0.3)=0.2*0.7=0.14

3) The horse lose the first race, but win the second one. The value will be $50k-$20k=$30k.

The probability is:

P(lw)=(1-P(w1))*P(w2)=(1-0.2)*0.3=0.8*0.3=0.24

4) The horse lose both races. The value will be $10k-$20k=-$10k.

The probability is:

P(lw)=(1-P(w1))*(1-P(w2))=(1-0.2)*(1-0.3)=0.8*0.7=0.56

Then, the expected profit can be calculated as:

E(x)=\sum\limits^4_{i=1} {p_ix_i}\\\\E(x)=0.06*80,000+0.14*30,000+0.24*30,000+0.56*(-10,000)\\\\E(x)=4,800+4.200+7,200-5,600=10,600

Please help me with the question below
nata0808 [166]

Answer:

4

Step-by-step explanation:

If Judge is x years old and Eden is 6 years older, then Eden is x + 6 years old.

The second part tells us that Eden will be twice as old as Judge in two years.

This means that in two years: (Eden's age) = 2 * (Judge's age).

Since we know that Eden's age can be represented as x + 6 and Judge's age can be represented as x, we can write this: x + 6 = 2 * x

Simplify the equation:

x + 6 = 2x

6 = x = Judge's age (in two years)

If Judge is 6 two years later, then he must be 4 now.

To check our work, we can just look at the problem. Judge is 4 years old and Eden is 6 years older than Judge (that means Eden is 10 right now). Two years later, Eden is 12 and Judge is 6, so Eden is twice as old as Judge. The answer is correct.
