Answer:
If you round it to nearest tenth it will be 50
Step-by-step explanation:
14x3.14=49
Answer:
x length
y width
2x=y
2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle
The answer is 12/100 or 12% probability.
The total group is 100 people, with only 12 being moderate that are high school only.
Answer:
A. The value of his investment decreased by 16% during this time period.
Step-by-step explanation:
To answer this problem, suppose an amount n.
After a year in value of the investment is:
Now we calculate the rate of change of n with the following formula:
The value of the investment decreased by 16% with respect to the initial amount.
The correct answer is the option
A. The value of his investment decreased by 16% during this time period.
Answer:
D) f(x) = (1/2)^x
Step-by-step explanation:
at least that is what I think answer D is supposed to be.
I guess the other answer options are actually
A) f(x) = -2^x
B) f(x) = 2^x
C) f(x) = (1/2)^-x
let's look at the most interesting point here : (1, 1/2).
when x=1, then y = 1/2
A fails. because for x = 1 we get y = -2.
B fails. because for x = 1 we get y = 2.
C fails. because for x = 1 we get (1/2)^-1
and that is 1 / 1/2 = 2
so, the only function giving us (1, 1/2) is D, as
(1/2)¹ = 1/2
