If F(x)=2/3x^2+8x, what is the value of f(6)

Mathematics
1 answer:
Delvig [45]3 years ago
5 0

Answer:

f = 2x + 24/ 3

Step-by-step explanation:

Step 1: Divide both sides by x.

fx/x = 2/3 x^2 + 8x/x

f = 2x + 24/3

Your teacher announced a 50-point math quiz for tomorrow. The quiz will have 15 questions with word problems worth 4 points each
koban [17]

Answer:

5  word problems(4points each)      &      10 open (3 points each)

Step-by-step explanation:

O= open response

W= word problems

  W+O =15

4W + 3O = 50

multiply the first by -3 to eliminate O

-3W -3O = -45

4W  + 3O = 50

  AD BOTH

W = 5    ( 5 questions word problems)

O= 10   ( 10 questions open response)

  5x4 = 20

10x3 = 30

      20 + 30 = 50 points

Consider, pls, this solution:
according to the equation y= -3x²+6x+2, where a=-3, b=6 and c=2, and the rule x₀= -b/(2a):
<u>x₀=</u>-6/(-6)<u>=1</u>.

N(t) = 25t + 150 for 0&lt;=t&lt;6, (200 + 80t)/(2 + 0.05t) for t&gt;=8
nadezda [96]

Answer:

1600. This is a maximum limit of fish the pond can host.

Step-by-step explanation:

For \lim_{t \to \infty} N(t), we must take the part of this function valid for high values, i.e., the second part, where t \geq 8\\.

\lim_{t \to \infty} N(t)=\lim_{t \to \infty} \frac{200+80t}{2+0.05t}

Since we have two polynoms both in numerator and denominator, and both of them are of degree 1 (both linear), for high values of t, the main part of each polynom shall be the linear part, neglecting lower degree parts (in this case, constant terms):

\lim_{t \to \infty} \frac{200+80t}{2+0.05t}=\lim_{t \to \infty} \frac{80t}{0.05t}=\frac{80}{0.05} = 1600

This means that the number of fish in a pond has an <em>horizontal asymthote</em>. In other words, there seems to be a natural limit for the number of fish that there will be in the pond as years pass. The maximum number of fish is actually 1600. With this function, no higher than this figure can be reached. This might imply <em>limits in productivity</em>.
