Answer:
Step-by-step explanation:
If t is the number of days since Sofia took the medication of 10 mg, then the amount of medication in her system after t days will be 
.
So, the concentration of medicine in blood decreases by a factor of one half every day.
If we count the number of days from today and Lexi takes 10 mg of the same medicine four days later then the amount of medicine left on her body after t days will be . (Answer)
Answer: The height of the kite above the point at which the string is held is 
feet.
Step-by-step explanation:
Given : A kite is being flown at 
. The string of the kite is 120 feet long.
Let AB denote the string of kite and AC be the height of the kite above the point at which the string is held.
Now, in right Δ ABC
hence, The height of the kite above the point at which the string is held is feet.
2 consecutive even integers : x and x + 2
4(x) + 3(x + 2) = 20
4x + 3x + 6 = 20
7x + 6 = 20
7x = 20 - 6
7x = 14
x = 14/7
x = 2
x + 2 = 2 + 2 = 4
so ur first number (x) = 2 and ur second number (x + 2) = 4
Let x represent the number.
.. x^2 +x = 2
.. x^2 +x +1/4 = 9/4 . . . . add 1/4 to complete the square
.. x +1/2 = ±3/2 . . . . . . . .square root
.. x = -2, 1
Numbers meeting that requirement are -2 and 1.
Answer:
$0.63
Step-by-step explanation:
Raoul saves $14.50 each month for 3 months. Total amount saved is 14.50 * 3 = $43.50
He earned an interest of $0.33.
The total amount of money he has is thus: 43.50 + 0.33 = $43.83
Hector puts $3.60 each week for 12 weeks. Total amount save by Hector is thus 3.60 * 12 = $43.2
Now we are asked to get how much money Raoul has. To get this, we simply subtract the amount of money Hector has from that of Raoul
That would be 43.83 - 43.2 = $0.63
