To find this we can divide 315 ÷ 22.5 = 14.
It will take 14 minutes for the balloon to descend 315 feet.
hope this helps!
(−0.0081p)(t)=(15000)(2.718282)
Step 1: Divide both sides by -0.0081t.
−0.0081pt
−0.0081t
=
40774.227427
−0.0081t
p=
−40774.227427
0.0081t
Answer:
p=
−40774.227427
0.0081t
The answer
the only method for finding the answer is computing directly the value of O(20) by replacing n by 20,
since we know that <span>O(n) = 2n - 1
so, we get </span>O(20) = 2*20 - 1 = 40-1=39
the answer is <span>D. 19</span>
A. (-3,5)(0,7)
slope = (7 - 5) / (0 - (-3) = 2/3
y = mx + b
slope = 2/3
(0,7)...x = 0 and y = 7
sub and find b, the y int
7 = 2/3(0) + b
7 = b....this is ur y int (0,7)
so ur equation for this line is : y = 2/3x + 7
b. (6,2)(9,4)
slope = (4 - 2) / (9 - 6) = 2/3
y = mx + b
slope(m) = 2/3
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 2/3(6) + b
2 = 4 + b
2 - 4 = b
-2 = b...this is ur y int (0,-2)
so this equation is : y = 2/3x - 2
so " a " has a slope of 2/3 and a y int of 7 and " b " has a slope of 2/3 and a y int of -2.
ur lines are parallel lines.....parallel lines will have the same slope and different y intercepts <===
1 kg = 1000 g....so 2.5 kg = (2.5 * 1000) = 2500 grams
it cooks 30 minutes per 500 g.....2500/500 = 5...so there are 5 thirty minute periods ....(5 * 30) = 150 minutes....plus the extra 20 minutes....(150 + 20) = 170 minutes....so your answerr is 2 hrs 50 minutes
