Answer:
1. 9-2=7
2. -6-(-4)=-2
Step-by-step explanation:
a=9
b=2
c=-6
d=-4
Answer: B
We all know that area= LxW
The width that is being shown is 8ft. The length is 20ft. Therefore, you multiply 8 x 20 which gives you 160ft squared. Hope this this helps :)
Theres 1760 yards in a mile so divide that by 2.
answer is 880
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:
AB = 7, BC = 7 and AC = 11
Step-by-step explanation:
Let AB = BC = a and CA = b
Now, given that the perimeter of the triangle is 25.
So, 2a + b = 25 ............ (1)
And 4 is the difference between the two unequal sides.
Hence, b - a = 4 .............. (2)
⇒ 2b - 2a = 8 ........... (3)
Now, solving equations (1) and (3) we get, 3b = 25 + 8 = 33
⇒ b = 11
Hence, from equation (2) we get a = b - 4 = 7
Therefore, AB = 7, BC = 7 and AC = 11 (Answer)
