Answer:
21,845
Step-by-step explanation:
The sum of geometric sequence:
S n = a 1 * ( q^n - 1 ) / ( q - 1 )
where: a 1 = 1,
q = a 2 : a 1 = 4 : 1 = 4
S 8 = 1 * ( 4^(8) - 1 ) / ( 4 - 1 ) =
= ( 65,536 - 1 ) / ( 4 - 1 ) = 65,535 / 3 = 21,845
Y=mx+b
2y-3x=7
2y=3x+7
y=3/2x+7/2
slope(m) = 3/2
In order to find the Y intercept you have to have at least one pair of coordinates from the line and plug it into the slop intercept formula OR you can just look at y=3/2x+7/2 on a graph to see where the line crosses the y-axis with the x value of zero , unfortunately I don't have a graphing calculator and you did not provide coordinates but hopefully this helped c: !
Hey there,
Answer:
Angle sum in triangle = 180 °
14 : 5: 11
Total units = 30u
30 units = 180°
1 unit = 180° / 30
= 6°
14 units = 6 x 14
=84°
5 units = 6 x 5
= 30°
11 units = 11 x 5
= 55°
Hope this helps :D

Answer:
The fencing will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of what comes out 1 foot of fence
45.53 * $7.25 = 330.0925
Round to the nearest hundredth
$330.0925 = $330.09
i think it is 44.4 degrees or 41.1 degrees.
