Answer:
Common ratio = 1/2 and first term = 384
or common ratio = -1/2 and first term = -384.
Step-by-step explanation:
T6/T4 = r^5 / r^3 where r = the common ratio and T6 and T4 are 6th and 4th terms
r^5 / r^3 = 12/48
r^2 = 1/4
so r = +/- 1/2.
The 4th term = a r^3 where a = first term.
If r = 1/2:-
48 = a *(1/2)^3 = a/8
a = 8*48
= 384.
if r = -1/2, then a = -384
Answer:
it is increase
234-24 = 210
210/24=8.75 x 100
875%
Step-by-step explanation:
<h3><u>
The value of x is equal to 21.</u></h3>
13 = 5 + 2(x - 17)
<em><u>Distributive property.</u></em>
13 = 5 + 2x - 34
<em><u>Add 34 to both sides.</u></em>
47 = 5 + 2x
<em><u>Subtract 5 from both sides.</u></em>
42 = 2x
<em><u>Divide both sides by 2.</u></em>
x = 21
Answer:
R=0.39789 ft
Step-by-step explanation:
For the perfectly mowed lawn, after one revolution, you want the lawnmower to be exactly one lawnmower's width closer to the pole. This implies that one lawnmower width should wrap around the circumference of the pole every revolution. So for this lawnmower we want:
2πR=2.5
⇒R=2.5/2π
R=0.39789 ft
