Answer:
Option B is correct.
sum of given geometric series is, 255
Step-by-step explanation:
Evaluate the geometric series: 
we can write this as:

Formula for the sum of the geometric series:
for r > 1
where
a is the first term
n is the number of terms
r is the common ratio
In the given series:
common ratio (r) = 2>1, n = 8 and first term(a) = 1
Since,

and so on...
then substitute the given values in [1] we have;

or

Therefore, the sum of given geometric series is, 255
C. y=2(1/4)^x
B is just a linear functions and the other two aren't exponential functions
Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
From the question the original line is
y=1/4x+5
Comparing with the general equation above
Slope = 1/4
Since the lines are parallel their slope are also the same
Slope of parallel line = 1/4
So the equation of the line using point
(2,-9) and slope 1/4 is
<h3>

We have the final answer as

Answer:
Sin B = 5/13
Cos B = 12/13
tan A = 12/5
Step-by-step explanation:
Sin B = opposite side/ hypotenuse
Sin B = 5/13
Cos B = adjacent side / hypotenuse
= 12/13
tan A = opposite side /adjacent side
= 12/5
Y=x+5
x+y=33
x+x+5=33
2x+5=33
2x=28
x=14
