Answer:
f(0) =4
f(6) =8
Step-by-step explanation:
f(0) = ?
We know 0 is less than 5 so we use the first part of the step function
f(0) = 0+4
= 4
f(6) = ?
6 is between 5 and 7 so we use the second part of the step function
f(6) =8
Answer:
630
Step-by-step explanation:
The sum of an arithmetic sequence is given by ...
Sn = n(2a1 +(n-1)d)/2
For the sequence of numbers of bales, we have ...
a1 = 123, d = -11, n = 7
so the total number of bales in 7 trips around the field is ...
S7 = 7(2·123 +6(-11))/2 = 630
The total number of bales made is about 630.
_____
123 + 112 + 101 + 90 + 79 + 68 + 57 = 630
Answer:
x=1/2
Step-by-step explanation:
Set up the equation: 2x-1=0
Add one to both sides. 2x=1
Divide two by both sides: x=1/2
Therefore, x =1/2, or .5
Answer:
Step-by-step explanation:
L.C.M. of 5,2=10
so it should be of dimensions 10×10×10
it should have 5 cuboids in first row.
then it will make a cuboid 5×10×5
5 cuboids in the second row on top of first row .
Then it will make 5×10×10 cuboid
To make 10×10×10
double the cuboids to make the length=10 and height=10..
so in all 20 cuboids are needed.
2 rows of 5 cuboids on the floor and 2 rows of 5 cuboids on the top.
in all 10 cuboids of dimensions 5×2×5
so 9 more cuboids are needed to make a c
Answer:
there is a greater chance that she selects a even number because there are 4 even numbers and 3 odd numbers
