Answer:
root(9/31)
Step-by-step explanation:
Since you are writing an inequality, you will want to look for the sign you need to write in place of the equal sign. Since, in the context, it states "less then 60 dollars", you will need to use the < sign. Next, you will need to find the main value, 200, and put it on the left sign of the inequality sign. Since you pay the friend 12 dollars per week, you will want to subtract 12x from 200. Your equation should now be :
200 - 12x < 60
You would then solve. help any?
The domain is all real numbers and the range is all the reals at or above the vertex y coordinate (if the coefficient on the squared term is positive) or all the reals at or below the vertex (if said coefficient is negative).
Answer:
6.32 cm.
Step-by-step explanation:
We can see that the given glass is in form of a cone.
To find the height of liquid in glass we will use formula:
, where,
h= Height of cone.
l= Slant height of cone.
r= Radius of cone.
We can see from our figure that diameter of cone is 6 cm, so radius of cone will be half of 6 cm, that is 3 cm.
We have been given slant height equals to 7 cm.
Let us substitute our values in above formula to find the height of liquid in the glass.
Therefore, the height of liquid in the glass is 6.32 cm.
