Answer:
the total area is 15.6 square units
Step-by-step explanation:
hello,
you can find the total area dividing the shape into two known shapes
total area= area of the trapezoid +area of the semicircle
then
step one
find the area of the isosceles trapezoid using
where
a is the smaller base
b is the bigger base
h is theheight
A is the area
let
a=2
b=5
h=4
put the values into the equation
Step two
find the area of the semicircle
the area of a circle is given by
but, we need the area of half circle, we need divide this by 2
now the diameter of the semicircle is 2, put this value into the equation
find the total area
total area= area of the trapezoid +area of the semicircle
so, the total area is 15.6 square units
Have a good day.

Answer:
$210.25
Step-by-step explanation:
A set of
elements has
possible subsets, where two classes of those sets are the empty set (1) and all the possible singleton sets (
). So a set of
elements has
possible subsets with more than one elements. For Q1 take
.
Q2a. Assuming not containing the same digits twice also includes not numbers with three or four of the same digit, and assuming digits are chosen from the usual 0-9, there are
possible strings.
Q2b. The first three digits can be chosen freely from 0-9, while the last digit has to be one of 0, 2, 4, 6, or 8. This means you have
possible strings
Q2c. Any such string will take the form
,
,
, or
, where
has 9 possible choices (0-9 excluding 9, since we want exactly three 9s in any such string). So there are
possible strings.
