Answer:
The function g(x) simply takes the value x and turns it into its reciprocal value . Thus, for instance, the number 5 becomes , and becomes 2. Note that any value of x works in this function as long as is defined. As mentioned, fractions work as well as whole numbers, both for positive and negative values; the only value that does not work is 0, since is undefined (how many times can 0 go into 1?). Thus, the domain of the function is all x in where x ≠ 0. Let's look at the graph of the function also.
Step-by-step explanation:
The function f simply takes in input value x, multiplies it by 2, and then adds 3 to the result. We can therefore consider what constitutes the set of numbers that the function can accept as an input and what constitutes the set of numbers that the function can yield as an output.
For any square the area is given by
where
is the length of one side. (This comes from the general rectangle formula
with
).
To solve for
we take the square root of both sides:
Now we can substitute known values:
Answer:
95.4%
Step-by-step explanation:
Z(low)=-2 0.022750132
Z(upper)=2 0.977249868
Step-by-step explanation:
108 = 60%
1% = 60%/60 = 108/60 = 1.8
100% = 1%×100 = 1.8×100 = 180
how many do not study French ?
the remainder of the students. that is 40% (100% - 60%) or 72 students (40×1.8 or simply 180-108).
Answer:
C x=6
Step-by-step explanation:
4x-5=19
+5 on both sides
4x=24
divide both sides by 4
x=6
