A number that has only 2 factors

Mathematics
1 answer:
IrinaK [193]3 years ago
3 0

Answer:

I'm pretty sure that all of the Prime numbers only have two factors. Let's say 3 for an example.

Step-by-step explanation:

The number 3 only has the factors of 3 and 1.

The two factors are itself (of course) and 1 (any number can go into one).

Another way to do this if you had to find out an answer like this.

3x1=3. Any number that can go into itself times 1 has only 2 factors.

Or at least I think. This is probably wrong. So Sorry if it is.

klio [65]
So i'm assuming your eqtn is    h = -16t^2 + 27t + 10
and we're looking for t = ?    when  h = 0

=>  16t^2 - 27t - 10 = 0
        (16t + 5)(t - 2) = 0

t = 2  and t = -5/16

The profit that a vendor makes per day by selling x elephant ears is given by the function P(x)= -0.004x^2+3.2x-200. Find the nu
dezoksy [38]

Answer:

The number of elephant ears that must be sold to maximize profit is 400.

Step-by-step explanation:

Given that,

The profit that a vendor makes per day is given by

P(x)= - 0.004x² +3.2 x -200

where x is number of elephant ears.

P(x)= - 0.004x² +3.2 x -200

Differentiating with respect to x

P'(x)= - 0.008x+3.2

Again differentiating with respect to x

P''(x) = -0.008

For maximum or minimum P'(x)=0

- 0.008x+3.2=0

⇒0.008x=3.2

\Rightarrow x=\frac{3.2}{0.008}

⇒ x = 400

P''(x)|_{x=400} = -0.008

Since at x=400, P''(x)<0, the profit is maximize.

P(400) = -0.004×400²+3.2×400-200

          =440

The number of elephant ears that must be sold to maximize profit is 400.
