Answer:
2a + 4b = 44
a+b=15
Step-by-step explanation:
Call a the number of chickens, b the number of horses
We have: 2a + 4b = 44
a + b = 15
=> 2(a+b) = 30
<=> (2a + 4b) - (2a + 2b) = 14
2b = 14
=> b = 7
=> a = 8
So 8 chickens, 7 cows.
We know that
<span>Trinomial of degree 35 means a polynomial
that
a) Having three terms
b) highest degree is 35
examples
x</span>^35+x³+3
x^35+2x-8
x^35+x²+2
etc
Answer:
-1/4 & 1/4
Step-by-step explanation:
(-1/4)^2 = (-1)^2 / (4)^2 = 1/16
4^2 = 16
(-4)^2 = 16
(-8)^2 = 64
(1/4)^2 = (1)^2 / (4)^2 = 1/16
hope this helps! <3
Answer:
c
Step-by-step explanation:
Answer:
- geometric
- common ratio: -5
- a[n]=-5a[n-1]; 625
Step-by-step explanation:
<h3>A.</h3>
We start this problem the way we start all problems: we read the problem statement and observe the given data and relationships.
Here, we observe that the given numbers are all multiples (powers) of 5, <em>with alternating signs</em>. We know that an arithmetic sequence cannot have alternating signs, so this is <em>not an arithmetic sequence</em>.
We are familiar with the first few powers of 5, so we recognize the terms have a common ratio of -5. If terms have a common ratio, they are a geometric sequence, so this is a geometric sequence.
__
<h3>B.</h3>
As we observed in Part A, the common ratio is -5.
__
<h3>C.</h3>
The full recursive formula will include the initial value in the sequence:
a[1] = -5
a[n] = -5·a[n-1]
Then the next value is ...
a[4] = -5·a[3] = -5·(-125)
a[4] = 625
