8x3 + 10x2 – 8x + 1

Answer:
D.
Step-by-step explanation:
You know that 0.25 went to 2.00. That means that it's a 1.75 jump. In order to jump the other two prices up and keep the ratio the same, you must also jump them 1.75.
0.05 + 1.75 = 1.80
0.10 + 1.75 = 1.85
To double check the ration we can look back on the original. 0.05 to 0.10 is a scale of 0.05. 0.10 to 0.25 is a scale of 0.15
Then we look at our new one. 1.80 to 1.85 is a scale of 0.05. 1.85 to 2.00 is a scale of 0.15.
The ratios stayed the same, so this is the correct answer.

Answer:
Even Function
Solution:
For an even function:
f(x) = f(-x)
For an odd function:
f(x) = -f(x)
Since f(-x) = f(x), the given function is an even function.
Answer:
The answer is (1,2) I'm pretty sure that is the answer if it is not please tell me I'll check.
Answer:
Option (C)
Step-by-step explanation:
In the given circle, AB is a chord passing through the center O.
Therefore,chord AB is a diameter of the circle and OC is the radius.
AO = OB = OC
OC⊥AB, and length of OC = 7 cm
By applying Pythagoras theorem in right ΔBOC,
BC² = OC² + OB²
BC = 
= 
= 
≈ 9.9 units
Therefore, Option (C) will be the answer.
