H(x) = (8x)/x(x^2 - 81)
hx = 2^3(x^2 - 81)
hx = 2^3 • x^2 - 2^3 • 81
Answer:
24
Step-by-step explanation:
Statistically... this is just a permutation of 4
Answer:
This is the same as writing y = 650(0.907)^t
=====================================================
Explanation:
Exponential equations can be of the form y = a*b^t
- a = initial amount
- b = growth or decay factor
In this case, we have
- a = 650 mg to start with
- b = 1 - 0.093 = 0.907 as the decay factor
If we had exponential growth, then we'd compute 1 + 0.093 instead.
Based on those values, we go from y = a*b^t to y = 650(0.907)^t which is the same as writing
Other exponential forms are possible, but I think this form is the most intuitive. The 0.907 means that 90.7% of the sample remains after each year.
Answer:
100 texts
Step-by-step explanation:
Let the amount of text messages be x. Since we are looking at making both plans equal, we add the fixed monthly charges to the number of messages multiplied by the cost.
The total amount charged by Totally will be 30 + 0.2x
The total amount charged by Gnarly will be
40 + 0.1x
Now since we are trying to get the number of text messages that make both charges equal, we equate the two charges and that is:
30 + 0.2x = 40 + 0.1x
40 - 30 = 0.2x - 0.1x
0.1x = 10
x = 10/0.1 = 100 texts
Answer:
12
Step-by-step explanation:
to make 1 cup with 1/4 cup you need to put 4.
therefore;
number of 1/4 cups needed = 3x4=12
