This will take 9.2 weeks to grow to 13 cm tall. you simplify 5 1/5 and 1 3/10 and then add the two simplified answers together and get 9.2 weeks and that is your answer
Answer: 140
Step-by-step explanation: 2.5 x 4 = 10
10 x 14 = 140
you multiply the amount of hours she swims for 4 days and then multiply those hours by 14 because the swimming season is 14 weeks long.
Answer:
Step-by-step explanation:
If this is an exponential function, it is of the form
where x and y are coordinates from your table, a is the intial value, and b is the growth/decay rate. To find out what the equation is that represents this data, choose 2 points and solve first for a and then for b. Just a hint: If at all possible, choose the coordinate that gives you an x of 0. You'll see why in a minute.
I chose the first 2 points from your table: (0, .2) and (1, .8). Solving first for a:
The reason to choose the x of 0 as one of your points is because anything raised to the power of 0 is 1. So our equation then becomes:
so
a = .2 Easy enough.
Now use that value along with the other coordinate to solve for b:
b to the first is just b, so,
.8 = .2b
Divide both sides by .2 and you'll get that
b = 4
The equation, then, is
which is growth, since the value for b is greater than 1.
Let's find the value of given expression for x = 5 ~
now, plug in the value of x as 5
so, the equivalent value is 60
