Answer:
I'm sorry is there a chart/graph, etc. to give us more information?
Without the added information there is no way for me to answer.
If you repost this question with a picture I would be more than happy to help.
Answer: yes, because it is useful to describe changes in the behavior of the thing we are describing.
Step-by-step explanation:
A piecewise function f(x) is a function that is "different" depending on the range of the values of x, this is for example:
y = x -----> if x < 0
y = x^2 ----- if x ≥ 0
This is used to represent changes in the behavior of the thing we are describing.
For example, suppose an object that is moving with constant velocity, the velocity graph will be a constant line.
Now, the object suddenly, at a time t = t0 accelerates to a constant acceleration A, now the graph of the velocity is a linear graph with slope equal to A.
So this situation can be represent this with a piecewise function:
V(t) = c -----> if t < t0
V(t) = c + A*t -----> if t ≥ t0
So the answer is yes, we can.
Answer:
b= 26
Step-by-step explanation:
there are 2 triangles
area of the right angles triangle
1/2bh= 1/2 x3 x4 = 6cm²
for the next triangle we use pythagoras theorem to calculate the height
3²+4² = h² = 9+16 = 25
h = √25 =5
1/2bh = 1/2 x 5 x8 = 20
adding the two areas will give the area of the figure = 20 + 6 = 26
