For
|a|>15
assume
a>15
a<-15
so
x+6>15
minus 6
x>9
x+6<-15
minu 6
x<-21
B is answer
Answer:
so the answer from paper is DC
Answer:
A coin toss
Step-by-step explanation:
if you flip one coin repeatedly like 10 to 10000 it can be 0.5
Answer: The correct answer is Volume Cone = one-third pi t squared k
Step-by-step explanation: The first important detail to note here is that both cylinder and cone have the same base and the same height This implies that when writing out the formula for calculating the volume of either of the two shapes, the radius and the height will be the same number or value.
The volume of a cylinder is given as;
Volume cylinder = pi x r squared x h (that is πr²h)
Also the volume of a cone is given as;
Volume cone = one-third x pi x r squared x h (that is 1/3*πr²h)
However, the variables have been changed such that the radius r is now represented by t while the height h is now represented by k.
Therefore the volume of the cone should now be re-written as;
Volume cone = one-third pi t squared k <em>(that is 1/3 *πt²k)</em>
Yes, you're right! The first step is rewriting the equation as
Subtract 
from both sides:
Use the property 
to rewrite the equation as
Divide both sides by 
Alternative strategy:
Consider both sides as exponents of e:
Use 
to write
Divide both sides by a:
Consider the logarithm base b of both sides:
The two numbers are the same: you can check it using the rule for changing the base of logarithms
