That is where the line crosses the x axis or where y=0
set y=0
Bx=A
find x value
divie both sides by B
x=A/B
the x intercept is x=A/B
Jana was prescribed medication. m = 250(0.75)^h
6 hours after Jana took her medication, Allison was prescribed the same.
m=250(0.75)^(h-6)
<span>At any time after she has taken the medication, Allison has how many times more milligrams of medication in her body?
</span>
Same with Jana, Allison's medication content in her body will decrease by 25% after each hour.
Let h = 6
Jana: m = 250(0.75)^6 = 250(0.178) = 44.50
Allison: m = 250(0.75)^6-6 = 250(1) = 250
250 - 44.50 = 205.50
On hour 6, Allison will have 205.5 mg more of the medicine than Jana.
Answer:
120.
Step-by-step explanation:
Since Alex and 4 friends are playing baseball on the same team, and each time they play a game, they switch the batting order to a sequence that has not yet been used, to determine what is the maximum number of games they can play before they have to repeat a batting order they have already used, the following calculation must be performed:
1 x 2 x 3 x 4 x 5 = X
2 x 3 x 4 x 5 = X
6 x 4 x 5 = X
24 x 5 = X
120 = X
Thus, the maximum number of games they can play before they have to repeat a batting order they have already used is 120.
<span> Nina + her 5 friends = 6 people
Then she has 9 apple to share with her and her friends.
Let’s calculate how many apple will each people get when they equally divide it
with each other:
=> 9 – 6 = 3
Thus already have 1 apple each, now, let’s divide the remaining 3 apples
=> 3 / 6 = .5
So they have half of apple each. Let’s add
=> 1 + .5 = 1.5
Each person will get 1.5 apple.
=> 1.5 * 6 = 9</span>
