Answer:
2 and 1.
Step-by-step explanation:
Answer: -31
<u>Step-by-step explanation:</u>
f(x) = -x⁴ + 3x³ + x² - 8x - 16
f(3) = -(3)⁴ + 3(3)³ + (3)² - 8(3) - 16
= -81 + 81 + 9 - 24 - 16
= -31
Part A) It depends on how long the experiment will be the domain must start from zero and should go as long as the experiment will last.
Part B) y intercept would be the height of the plant after n days
Part C) 8(1.05)^2 = 8.82, 8(1.05)^6 = 10.72
10.72 - 8.82 = 1.9
6-2 =4
1.9 /4 = 0.475
this means the plant grows at an average of 0.475 cm per day
They would each get 1/4 of a pound (3 divided by 12)
Posted to your other question as well:
So we have:
A)
B)
C)
D)
We need to try x = –6 in each equation until we find a solution that makes both sides of the equation equal.
For A, this gives an undefined result. Logarithms are only defined for bases that are positive real numbers not equal to 1.
For B, this again gives an undefined result. The logarithm of a number is only defined when that number is a positive real number. It would be –21, which is undefined.
For C, we have a defined operation, but
.
Finally, for D, we have
This is true.
