Martins sisters age is 14 I got this My work (could be wrong)
Its pretty simple if they said Their sum of their ages is <u>22</u> all you have to do is 22-6= 14.
Hope this helps If you have any questions ask me in the comments :D
Answer:
Step-by-step explanation:
The initial population of bacteria is 800 and we know that this number is quadrupling every hour.
<u>We're going to find a function in terms of t (time) that gives us the population of bacteria at that time.</u>
Since the population is quadrupling every hour the function in terms of t (where t is expressed in hours) is:
Now we need to find the time when there will be 5,120,000 bacterias. This means the time t when f(t) = 5,120,000
So we have 5,120,000 = 
Therefore, the time when there will be 5,120,000 bacterias will be:

Answer:
Step-by-step explanation:
Next time, please enclose the quantity in the denom. inside parentheses, to eliminate any ambiquity regarding what the divisor is.
2x 2(x)
f(x) = --------------- = -------------------
3x² - 3 3(x - 1)(x + 1)
This is the same as:
2 x
--- * ------------
3 (x-1(x+1)
As x grows large, the 2nd fraction approaches 1/x as a limit, which goes to zero. Hence, the end behavior involves the x-axis as the horizontal asymptote. This agrees with the first answer choice.
Answer:
<h2>Frank speed = 37mi/h</h2><h2>Gregory speed = 59mi/hr</h2>
Step-by-step explanation:
Let the speed of Frank be x and speed of Gregory be y. If Gregory drives 22 miles per hour faster than Frank, then y = 22+x. SInce they they are 216miles apart after 2.25 hours,
Speed = Distance/Time
Total time travelled by them = 2.25hours
Total distance = 216 hours
Total speed = x+y = x+22+x
Substituting this parameters into the formula given to get x we will have;
x+22+x = 216/2.25
2x+22 = 96
2x = 96-22
2x = 74
x = 74/2
x = 37
<em>Hence the speed of Frank is 37miles per hour while that of gregory is 37+22 = 59miles/hour</em>
