Here are two shapes with the same area. Work out the perimiter of the rectangle.
Lilit [14]
So, we know the perimeter is 24 cm. and the top part is the left part, (x) + 2, but remember, we need to have it be a number that, multiplied by 2, is 24. So, using this formula, the length, (top / bottom) is 7, and x = 5. Because 5 + 5 = 10, and when length is +2, it adds up to 14. 10 + 14 = 24. So, length is 7, width, (left, right) is 5.

What is the 8th term of this geometric sequence 6,48,384,3072
ELEN [110]
Common ratio can be found by dividing the 2nd term by the first
r = 48/6
r = 8

an = a1 * r^(n-1)
n = term to find = 8
a1 = first number = 6
r = common ratio = 8
now we sub
a(8) = 6 * 8^(8-1)
a(8) = 6 * 8^7
a(8) = 6 * 2097152
a(8) = 12582912 <==

A cable installer charges $40. an hour plus a $50.00 service charge. Figure the function c(h) = ?
Hitman42 [59]

Answer:

c(h) = 40*h + 50

Step-by-step explanation:

Let h be the variable that represents the number of hours

As the cable operator charges $40.00 for an hour so for h hours, the expression will be 40*h

And  

Lastly, he has to charge $50.00 must as service charge,

As the number of hours is variable here so the function will be in terms of hours.

So the resulting function will be:

c(h) = 40*h + 50
