Answer:

120\ cm^2

Step-by-step explanation:

The area (A_t) of a triangle is equal to half the product of its length (L) because of its height (h).

A_t = 0.5h*L

The base of the triangles is L = 4\ cm

The height of the triangles is h = 5\ cm

Then the area of one of the triangles is:

A_t = 0.5(4)(5)\\A_t = 10\ cm^2

The figure is formed by 12 equal triangles, then the area of the figure (A_f) is:

A_f = 12(A_t)\\A_f = 12(10)\\A_f = 120\ cm^2

What is the domain of f(x) = cos(x)?
malfutka [58]

Answer:

Domain of the function f(x) = cos x : ( - infinity , + infinity)

Step-by-step explanation:

Let the given function f(x) = cos x

We need to find the domain set of the given function f(x) = cos x

Domain is the set of all possible value of x for which the function f(x) is defined.

Now, as the given function f(x) is defined for all the real values of x.

Domain of the function f(x) = cos x : ( - infinity , + infinity)

Hence, Domain : ( -∞ , +∞ )

Also, the graph of the given function f(x) = cos x is attached below :

Now, form the graph also we can see the graph of given function f(x) = cos x can attain all the real values starting from -infinity to +infinity

What is the probability that a leap year selected at random will contain either 53 thursdays or 53 fridays?
sergij07 [2.7K]
<span>There are 366 days in a leap year
 In a week there are 7 days, so total no of days= 7*52=364 days.
  Here 52 represents number of weeks.
  Now last two days can be combination of two days say like Monday and Tuesday or Tuesday and Wednesday and so on.
 So in total 7 combinations are possible.
 Out of there can be 3 combinations containing Thursday or Friday.
 Hence, the probability is 3/7.
 Hence the answer is 3/7</span>
