Answer:
Option (B)
Step-by-step explanation:
From the graph attached,
There are two functions graphed,
y = f(x) and y = h(x)
h(1) = 0 [Output value of function 'h' at the input value x = 1]
Since, g[h(1)] = g(0)
Therefore, value of function 'h' (output value) at (input value) x = 0,
g(0) = -5
Option B will be the correct option.
Answer:
This can be done in a total of 10 ways
Step-by-step explanation:
This is a selection problem.
What we are trying to do is to properly select 3 week long camps from the total 5. we are looking for the number of ways in which we can do this.
Now, since this is a selection problem, the proper mathematical term and approach to use is the COMBINATION
Mathematically, having r items to pick from a total n, the number of ways to do this is nCr ways
which is mathematically equivalent to;
n!/(n-r)!r!
now applying this to the problem at hand, what we have is 5C3
= 5!/(5-3)!3! = 5!/2!3! = (5 *4)/2 = 20/2 = 10 ways
7x9=63/2=31.5
31.5x4= 126
7x7=49
126+49=175
The surface area of the pyramid would be 175cm^2
