Answer:
Shapes are similar when one can be scaled to be like another one. Circles are always the same shape and they only vary in size. A very small circle can be expanded to be the same size as any other without changing it's shape, only size. However this is not true for ovals since they come in different shapes.

Answer:
3/4
Step-by-step explanation:
There is 2 Os and 8 in total.
So the probability of selecting O is 1/4
As the question asks everything but O, you subtract that answer from 1. 1-1/4=3/4
150,000 = 50000a^20
a^20 = 150000/50000 = 3
a = 20th root of 3 = 1.056467
Required equation is P = 50000(1.056467)^t
Answer:
3/2
-4
Step-by-step explanation:
y = mx + c
m = slope = y2 - y1 / x2 - x1
= -4 -2 / 0 - 4
= -6/-4
= 3/2
c = y intercept
y when x = 0
c = -4
Answer:
a. y = 1/(x + 2) + 3
Step-by-step explanation:
From the description of the function, it is seen that the curve has an asymptote at x = -2. Asymptotes are typical from rational functions. The only option that matches this feature is y = 1/(x + 2) + 3
Moreover, replacing x = 0 into the equation, we get:
y = 1/(0 + 2) + 3 = 3.5
And replacing y = 0 into the equation, we get:
0 = 1/(x + 2) + 3
-3 = 1/(x + 2)
x + 2 = -1/3
x = -1/3 - 2
x = -2.33 ≈ -2.5
