We are to find the graph which best represents the given function:
f (x) = 5 (2)^-x
To be able to solve this, let us write the function of each graph mathematically
and select the correct one.
Graph A:
function f of x equals 5 multiplied by 2 to the power of negative x =>
f (x) = 5 (2)^-x
Graph B:
function f of x equals 5 multiplied by 2 to the power of x => f (x) = 5
(2)^x
Graph C:
function f of x equals 10 to the power of x => f (x) = 10^x
Graph D:
function f of x equals 10 to the power of negative x => f (x) = 10^-x
Therefore based on the mathematical interpretations above, only Graph A is
similar to the given function. Hence the correct answer is:
Graph A
Answer:
thirteen sixteenths
Step-by-step explanation:
Three eighths plus seven sixteenths equals blank
3/8 + 7/16 = ?
= (2*3)+(1*7)/16
= (6+7)/16
= 13/16
13/16 is equivalent to thirteen sixteenths

Answer:
parallelogram
Step-by-step explanation:
Looks like a rectangle, but then angles should be marked =90
But two sides are marked equal that makes it a parallelogram.
(a parallelogram is 4 sided figure where 2 opposite sides are =
