Answer:
The first term of the geometric series is 1
Step-by-step explanation:
In this question, we are tasked with calculating the first term of a geometric series, given the common ratio, and the sum of the first 8 terms.
Mathematically, the sum of terms in a geometric series can be calculated as;
S = a(r^n-1)/( r-1)
where a is the first term that we are looking for
r is the common ratio which is 3 according to the question
n is the number of terms which is 8
S is the sum of the number of terms which is 3280 according to the question
Plugging these values, we have
3280 = a(3^8 -1)/(3-1)
3280 = a( 6561-1)/2
3280 = a(6560)/2
3280 = 3280a
a = 3280/3280
a = 1
Answer:
See below
Explanation:
You multiply 8 and 6.9
To get 55.2 ounces
Answer:
the answer is A because the cost of the more expensive one is 15+20=35 multiplied by 3 which will give me =$105
And the cheaper one is 15+20=35 multiplied by 1.50 = which is 52.5
so the amount more of the choice for the more expensive one is 105-52.5=52.5.
the answer is 52.50.
Answer:
Option C is correct.
The y-intercept of the graphed function is; 
Explanation:
To find the y-intercept of the graphed function:
The point where the graph crosses the y-axis is call y-intercept.
You can also find the y-intercept by looking at the given graph and seeing which point crosses the y-axis also this point will always have an x-coordinate of 0.
End behavior of a polynomial function is the behavior of the graph of function as x approaches 
or 
Also, the degree and the leading coefficient of a polynomial function determine the end behavior of the graphed function.
therefore, the y-intercept of the graphed function is; (0, -9)
