c. -8
Step-by-step explanation:
Given:
a = 5, b = 8, and c = 1
To evaluate, plug in the values into the expression given.
Thus:
Answer:
Step-by-step explanation:
The value of the function f(x) at x=a can be determined by substituting a instead of x into the function expression.
1. When x=-1, then
f(-1)=2\cdot (-1)^3-3\cdot (-1)^2+7=-2-3+7=2.
2. When x=1, then
f(1)=2\cdot 1^3-3\cdot 1^2+7=2-3+7=6.
3. When x=2, then
f(-1)=2\cdot 2^3-3\cdot 2^2+7=16-12+7=11.
Answer:
The rate of Yvone's hair growth is 3.1 cm per month.
Step-by-step explanation:
WIth the data from Yvonne's hair we can create a sequence that goes as follows:
A = {47, 50.1, 53.2, 56.3, 59.4,...}
This is an arithmetic sequence, the numbers are related to each other by a common difference, in other words to find the next number we just need to add a constant "r". To find this constant we can subtract any adjacent numbers on this sequence, this is shown below:
r = 50.1 - 47 = 3.1
r = 53.2 - 50.1 = 3.1
r = 56.3 - 53.2 = 3.1
and so on.
The rate of Yvone's hair growth is 3.1 cm per month.
