For the series:
- 5 + ( - 1 ) + 3 + 7 + 11
common difference between the numbers is 4 and a 1 = -5
The series in sigma notation:
4
∑ ( 4 i - 5 )
i =0
i’m pretty sure
Slope 2
Slope intercept form y=2x+5
y-int is 5
Slope 4
Slope intercept form y=4x+22
y-int 22
i hope this helps a little buh i’m sorry in advance
I think it’s the last one!
I will right it sideways. you can use this strategy later on if you would like. I put (parentheses) around what is optional to include. the = to the left of the second word number is to show that the number is equal. if there are two different variables you would put a crossed out equal sign.
_______________
eight= 8 l
more than= +
six= 6
times= x
(a)number= n l
_______________
added (to)= +
_______________
one= 1 l
more than= +
= number= n l
_______________
(I tried to do parentheses)
then, you rewrite what you wrote beside the words!
(8+6n)+(1+n)
that is your equation!
Answer:
$95.38
Step-by-step explanation:
step 1
Find the area of one button
The area is equal to
we have
---> the radius is half the diameter
Convert to meters
assume
substitute
step 2
Find the area of 1,00 buttons
Multiply by 1,000
step 3
Find the cost
Multiply $15 per square meter by the total area of 1,000 buttons
