How do I find the maximum profit of -30x2+660x-1500

lina2011 [118]

Answer:

2,130

Step-by-step explanation:

1. solve for x.

$x=-\frac{b}{2a}$

when $ax^{2} +bx+c$

$x=\frac{-660)}{2(-30)}\\\\x=\frac{-660)}{-60}\\\\x=11$

2. place value for X into equation

$y=-30x^{2} +660x-1,500\\y=-30(11)^{2} +660(11)-1,500\\y=-30(121)+7,260-1,500\\y=-3,630+7,260-1,500\\y=3,630-1,500\\y=2,130$

Maximim profit is 2,130.

In the sequence 400, 200, 150, 75, 25...... what number comes next

Scorpion4ik [409]

Answer:

The next term in the sequence = -175

Step-by-step explanation:

Here, the given sequence is : 400, 200, 150, 75, 25...

Now here, in the given sequence,

First Term - Second Term = 400 - 200 = 200

Second Term - Third Term = 200 - 150 = 50

Third term - Fourth Term = 150 - 75 = 75

Fourth term - Fifth term = 75 - 25 = 50

So, following this pattern,

Fifth Term - Sixth term = 200

Or, 25 - Sixth Term = 200

or, Sixth term = 25 - 200 = - 175

Hence, the next term in the sequence = -175
