This would be simplified as following: r^2 t^4
25 and 65 because 90 and 90 makes a square
Answer:
(-∞, ∞)
Step-by-step explanation:
Given,

Then (fºg)(x) would be ,

Since this is a polynomial, we know domain of a polynomial is all real number.
Therefore the domain of this (fºg)(x) is (-∞, ∞).
Answer:
1: C, ten from each class
2: 27
3: the numbers are counted incorrectly.
4: 5.5 hours
5: 6 hours
Step-by-step explanation:
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
