Answer:
-5n + 8
Step-by-step explanation:
<u>1. What is the difference?</u>
The sequence goes down by 5. This means that the formula will have -5n in it.
<u>2. Work out the term before the first term.</u>
The first term is 3, and we know that the sequence goes up by 5. So, to get the term before 3 we would add 5.
3 + 5 = 8 Remember, this is positive 8. (+8)
<u>3. Put that term at the end of the equation. </u>
We have -5n already and we just worked out the term before the first one which is positive 8 - so put that at the end of the equation.
-5n + 8 This is our answer!
Just to prove it works:
<em>Substitute: n = term</em>
Lets see if we can get the 3rd term which is -7. (n = 3)
-5(3) + 8
-15 + 8 = -7
See, it works!
The graph is attached.
Answer:
(-2.2, 4) and (8.2, 4)
Step-by-step explanation:
In an ellipse, there is a minor radius and a major radius.
Let major radius be = a
Let minor radius be= b
From the graph, we are given:
Major radius, a = 6
Minor radius, b = 3
Now, let's find the distance from the center to the focus using the formula:
Substituting values, we have:
≈ 5.2
We can see from the graph that center coordinate is (3, 4). Therefore, the approximate locations of the foci of the ellipse would be:
(3-5.2, 4) and (3+5.2, 4)
= (-2.2, 4) and (8.2, 4)
8.379 as a mixed number is 8 and 379 over 1000.

Answer:
Step-by-step explanation:
7 lenthii=38 inches, 10 lenthii=410
410-225.3=184.7
184.7+38=222.7 222.7+38=260.7
260.7- 4 lenthii=225.3
Answer:
H = 45
J = 45
K = 135
Step-by-step explanation:
The total should be 360 degrees, and we know that J and H are the same since, uh I don't know (forgot the vocab word for it).
45 + 45 = 90
360 - 90 = 270
270/2 = 135
135 is the degree for I and K since, uh I don't know (forgot the vocab word for it).
