4. 1 less than twice the square of a number

Mathematics
1 answer:
givi [52]3 years ago
5 0

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D

A fried chicken franchise finds that the demand equation for its new roast chicken product, "Roasted Rooster," is given by q = 3
sdas [7]

Answer: E(p) = 6/7√37/q

Step-by-step explanation: if q = 37/p^0.85, then we are to make p the subject formula.

Now multiply both sides by p^0.85, we will have

P^0.85q = 37

Divide through by q, we get

P^0.85 =37/q

But 0.85 = 6/7

So we take the 6/7 root of both sides, we get

P = 6/7√37/q

Therefore E(p) = 6/7√37/q
