Answer:
c
Step-by-step explanation:
The answer is B hopefully this helped
To find it it is
ax^2+bx+c
if the first term (a) is 1 then c=b/2
b=-1/4
(-1/4)/2=-1/4 times 1/2=-1/8
k=-1/8
Answer:
330
Step-by-step explanation:
575 - 163 = 412
412 / 1.25 = 329.6
Since we need to exceed the goal and we can only sell whole candy bars, we round 329.6 up to 330.
The sum of the first n terms in a geometric sequence given the first term (a1) and the common ratio (r) is calculated through the equation,
<span>Sn </span>= (<span><span><span>a1</span>(1−<span>r^n</span>) / (</span><span>1−r)
Substituting the known terms,
Sn = (20)(1 - (1/4)^4)) / (1 - 1/4)
Sn = 26.5625
Thus, the sum of the first four terms is 26.5625. </span></span>
