Question

a small manufacturers weekly profit in peso is given by P=3xsquared + 70x
find the number of items x
that must be produced to
realize a profit of P4,200

EQUATIONS :
4,200=-3xsquared -70x
+3x squared -70x + 4,200 =0

.. QUESTION .. what will be the answer ..
plz answer , i need it on my retrice !

Answer 1

Simply looking for answer is against our Code of Conduct ( http://openstudy.com/code-of-conduct). We are here to help you understand how to do it, but not help you do your homework.

As, for your question, is the equation ''4,200=-3xsquared -70x'' given in the question or you did it yourself?

Answer 2

nope!

Answer 3

That means it's not given in the question?

Answer 4

was not found ?

Answer 5

i dont know ?

Answer 6

Is the following your workings?
EQUATIONS :
4,200=-3xsquared -70x
+3x squared -70x + 4,200 =0

Answer 7

It's quite strange to me...
In your question:
\(P=3x^2+ 70x\)
find the number of items x that must be produced to realize a profit of 4,200
Put P = 4200 into the equation.
\(4200=3x^2+ 70x\)
\(3x^2+ 70x-4200 = 0\)
Solve it using quadratic formula \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)
Identify a, b and c for your question. Can you do it?

Answer 8

no .. im not good in mth!

Answer 9

Hmm.. the general quadratic equation is
\(ax^2 + bx +c = 0\) Now you have
\(3x^2 + 70x - 4200 = 0\)
Can you compare the two now?

Answer 10

no

Answer 11

What is the coefficient of \(x^2\) ?

Answer 12

x ?

Answer 13

No. Coefficient of \(x^2\) is the number (or a variable, sometimes) in front of \(x^2\).
