If you work out the constants it says:
25+x²=100
Which simplifies to x=√75 or x=-√75
Answer: b
Step-by-step explanation: The graph shows that the maxiumum x is -1 and it can go lower. You plug them in and b is the right answer.
Answer:
S.A. = 981.7 ft^2
Step-by-step explanation:
radius = 25 ft
S.A. = 1/2πr2
S.A. = 1/2π(25)^2
S.A. = 981.7
Answer:
64 Chickens
Step-by-step explanation:
1. Add up the percents
19% + 28% + 13% = 60%
2. Subtract from 100%
100% - 60% = 40%
3. Multiply the total number of animals by the percent of chickens
160 * .4 = 64 Chickens
The answer is (rounded to the nearest tenth) about 5.7 and since neither 18 or 2 have a perfect square, so this is irrational.
