Answer:
- a) f(x) = - 20x + 450
- b) 30 pages left to read
Step-by-step explanation:
<u>Given sequence:</u>
The first term is 430 and the common difference is - 20.
a)
<u>Required function is:</u>
- f(x) = 430 - 20Ix - 1) = 430 - 20x + 20 = 450 - 20x
or
b)
<u>Find the number of pages left after 21 days:</u>
- f(21) = 450 - 20*21 = 450 - 420 = 30

We interpret the smudges in your attachment to be dimensions of 1 1/2, 4, and 1 1/2. The volume is the product of these.
V = LWH
V = (4)(1.5)(1.5) = 9 . . . . cubic units
The volume of the prism is 9 cubic units.
Answer:
C
Step-by-step explanation:
1. If it is to the power of a negative, you do the reciprocal, so you know the answer will be 1/y.
2. If it is to the power of 4/3, you know it is ![\sqrt[3]{y} ^{4\\}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%7D%20%5E%7B4%5C%5C%7D)
(y cubed to the power of 4), so the whole answer is 1/
Answer:
total of 36 students
Step-by-step explanation:
only Tennis = 2
only Football = 2
only Baseball = 4
Tennis/Football = 3
Football/Baseball = 14
Baseball/Tennis = 11
All = 6
