Answer:
$0.95
Step-by-step explanation:
Given that weight of the function = x
Given that cost of the postage for mail having weight less than or equal to 1 oz = $0.44
then to find the equation can be written as
C(x)=0.44 where 0<x<=1
Similarly we can write equation for other parts
C(x)=0.61 where 1<x<=2
C(x)=0.78 where 2<x<=3
C(x)=0.95 where 3<x<=3.5
Now we can write them together as piecewise function as shown in below:
to graph that we just draw horizontal lines for each as none equation contains x on the right side .
3.48 oz is less that 3.5 so we will use $0.95.
Answer:
(-4, 3] U (3, 8]
Step-by-step explanation:
The first lines range is (-4,3]
(the round bracket is because the -4 not included ( clear circle) and the square on because the 3 is included in the range ( the filled circle))
second line - range is (3, 8]
So its (-4, 3] U (3, 8]
14%=56%
56%=56/100=0.56
14=0.56 of all
14=0.56 times all
divide both sides by 0.56
25=all
25 performers total
Answer:
(0,1)
Step-by-step explanation:
Let (0,3) lies on f(x), then:
Let
To find the corresponding point that lie on g(x), we substitute x=0
This implies that:
But f(0)=3
We substitute to get:
The required point is (0,1)
Answer:
A
Step-by-step explanation:
Because 4 minutes times 15 equals an hour 3 x 15 is 45.
And 3 minutes times 20 equals an hour 2 x 20 is 40 so the difference is 5
