Answer:
Divide: 2 : 1
8
= 2
1
· 8
1
= 2 · 8
1 · 1
= 16
1
= 16
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1
8
is 8
1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
In words - two divided by one eighth = sixteen.
SO FINAL ANSWER IS 16!!! HOPE THIS HELPS YOU mark me the brainliest if im correct
The answer is < because 7.1983 * 10^1 =71.983
Answer:
Step-by-step explanation:
I'm sure you want your functions to appear as perfectly formed as possible so that others can help you. f(x) = 4(2)x should be written with the " ^ " sign to denote exponentation: f(x) = 4(2)^x
f(b) - f(a)
The formula for "average rate of change" is a.r.c. = --------------
b - a
change in function value
This is equivalent to ---------------------------------------
change in x value
For Section A: x changes from 1 to 2 and the function changes from 4(2)^1 to 4(2)^2: 8 to 16. Thus, "change in function value" is 8 for a 1-unit change in x from 1 to 2. Thus, in this Section, the a.r.c. is:
8
------ = 8 units (Section A)
1
Section B: x changes from 3 to 4, a net change of 1 unit: f(x) changes from
4(2)^3 to 4(2)^4, or 32 to 256, a net change of 224 units. Thus, the a.r.c. is
224 units
----------------- = 224 units (Section B)
1 unit
The a.r.c for Section B is 28 times greater than the a.r.c. for Section A.
This change in outcome is so great because the function f(x) is an exponential function; as x increases in unit steps, the function increases much faster (we say "exponentially").
C. 100 is the aswer i thinck
You can divide 1000 by 4 then multiply a number to get 2500
1000/4= 250
250 x 10 = 2500
