F(x)=-4x^2+7x+6 how do you work this

Mathematics
1 answer:
Ainat [17]3 years ago
7 0

There actually isn't anything to 'work'.  There's no question there.

The function simply describes the relationship between two numbers.

It says that whatever you pick for the first number, the second number is

    (-4 times the square of the first one) plus (7 times the first one) plus (6) .

Your teacher may have assigned you something to do with the function,
like draw the graph of it, or find its maximum value (2.9375), or find where
it crosses the x-axis (2.381 and -0.63) or the y-axis (6).

But we can't tell what you've been assigned to do with it.  The function alone,
just as you've posted it, isn't asking a question, and doesn't call for any work.

A hardware supplier manufacturers 3 kinds of clamps types AB &c production restrictions force it to make 10 more type C clam
hichkok12 [17]

Answer:

Hardware supplier will manufacture 60 Type A clamps, 180 Type B clamps and 150 Type C clamps.

Step-by-step explanation:

Given:

Company produces 3 types of clamp

Type A

Type B

Type C

production restrictions force it to make 10 more type C clamps in the total of the other types

Hence We can say that Clamp C is equal to sum of Clamp A and Clamp and 10

framing in equation form we get;

C=A+B+10 \ \ \ \ \ equation \ 1

Also Given:

3 times as many Type B clamps as type A clamps

Hence we can say that Clamp B is equal to thrice of Clamp A.

B=3A \ \ \ \ equation\ 2

Also Given

Total Number of Clamps  = 490

Hence Total  Number of Clamps  is equal to sum of number of Clamps of Type A, Type B and Type C.

Framing in equation form we get;

A+B+C =490 \ \ \ \ equation \ 3

Substituting the equation 1 and Equation 2 in equation 3 we get

A+B+C=490\\\\A+3A+A+B+10=490\\\\A+3A+A+3A+10=490\\\\8A = 490-10\\\\8A=480\\\\A=\frac{480}{8}=60

Now Substituting the Value of A in equation 2 we get;

B=3A = 3\times60 =180

Now Substituting the values of A and B in equation 1 we get:

C=A+B+10 = 60+180+10= 250

Now checking the same we get;

A+B+C=490\\60+180+250=490\\490=490

Hence the Hardware supplier will manufacture 60 Type A clamps, 180 Type B clamps and 150 Type C clamps.
