Yes because they are at acute angels
Answer: first one a+3
next one 3(a+3)
next one (a+3)-3
next one a*3
part b
D divided by 4
D-4
4 divide by D
4-D
Step-by-step explanation:
Answer:
= - 5.6n + 3.2
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
= u₁ + (n - 1)d
where u₁ is the first term and d the common difference
To find u₁ use the given recursive formula
u₁ = u₀ - 5.6 = 3.2 - 5.6 = - 2.4
from the recursive formula d = - 5.6 , then explicit formula is
= - 2.4 - 5.6(n - 1) = - 2.4 - 5.6n + 5.6 = - 5.6n + 3.2
Yes, I agree with the researcher's method. All the values of in the table correspond to the values of n by using their formula.
Step-by-step explanation:
Step 1:
If we substitute the values of n in the researcher's equation and we get the right values of , we can agree with the researcher's method.
The researcher's formula is Here is the wombat population and n is the number of years.
Step 2:
When n = 1,
when n = 2,
when n = 3,
when n = 4,
when n = 5,
As all the values correspond to the values on the table, I agree with the researcher's method.
