Answer:
a=-4000m+39000
Step-by-step explanation:
From the given table, we can see that the difference between any consecutive altitude is 4000 ft.
31000 - 35000 = -4000
27000- 31000 = -4000
23000-27000 = -4000
Hence, it represents an arithmetic sequence with a = 3500 and d = -4000
The general term of an arithmetic sequence is given by
Answer:
x = 1
x = -5/8 + i* root( 39) / 8
or x = -5/8 - i* root( 39) / 8
Step-by-step explanation:
(x+x)^2 × -(x×(-1))=4+x-x^2
solve for x, show work.
(x+x)^2 × -(x×(-1)) = 4+x-x^2
Simplify:
(2x)^2 * (-(-x)) = 4 + x - x^2
4x*x * (-(-x)) = 4 + x - x*x
4*x*x*x = 4 + x - x*x
4*x*x*x - 4 = x *(1 - x)
4* (xxx - 1) = x * (1- x)
4* (x - 1)*( x*x +x + 1) = x (1 - x)
4( xx + x + 1) = -x
x = 1 is a solution.
4xx + 4x + 4 = -x
4xx + 5x + 4 = 0
x = -5/8 + root(25 - 4*4*4) / 2*4
x = -5/8 + i* root( 39) / 8
or x = -5/8 - i* root( 39) / 8
also x = 1
Answer:
$10.5
Step-by-step explanation:
4(5.25) = $21 (total amount of money spent)
we want to divide that by 2 because we want to find the cost of one pizza
21/2 = $10.5
The answer is 95ft
1. Set up an equation 52-x=-43
2. Subtract 52 from both sides -x=43-52
3. Simplify -x=-95
4. x=95
All the best (if you don't understand the equation let me know if you want help)
