Answer:
Once a month, the female releases an ovum (one egg) or sometimes two (ova). If an ovum has been released, and the couple have sex, a sperm can unite with it, fertilise it and make the first cell of a new baby. Once one sperm has fertilised the ovum, no other sperm can get in. For the sperm it's like a race and there is only one winner.

Answer:
(2x + 3)(x - 7)
Step-by-step explanation:
Rewrite Equations
x=10; y=−5x+30
Step: Solve x=10
for x: x=10
Step: Substitute
10 for x in y=−5x+30:
y=−5x+30
y=(−5)(10)+30
y=−20
(Simplify both sides of the equation)
Answer: x=10 y=-20 (10,-20)
Answer:
A:
Let x represent the price of a ticket and R represent the revenue.
Let r be the number of 1 $ reduction.
So,
=> .......(1)
As given that for every dollar the ticket price is lowered, attendance increases by 3000.
So, if we reduce the ticket price by r dollars, the attendance will increase by 3000r.
Revenue = price of ticket X number of ticket sold
R = .....(2)
Substituting the value of r from (1) in (2) we get;
Solving this we get;
B:
To maximize revenue, we have to find the derivative for
Setting this to zero:
=>
=>
x = 8.5
To maximize the revenue, the price should be $8.50.
C:
When R=0
=>
=> Either x=0 or x=17
x = $0 means there is no price for ticket, that is not possible, so we will neglect it.
And x = $17 means that the ticket price is so high, and no revenue will be generated.
