Answer:
145%.
Step-by-step explanation:
Given that the price of an item yesterday was $120, and today, the price rose to $294, in order to find the percentage increase, the following calculation has to be made:
120 = 100
294 = X
((294 x 100) / 120) = X
29,400 / 120 = X
245 = X
245 - 100 = 145
Therefore, the percentage increase of the product was of 145%.
7.875
-3/2 = -1.5
-5 1/4 = -5.25
-1.5 • -5.25 = 7.875
Answer:
Factors of 20: 1, 2, 4, 5, 10, 20.
Step-by-step explanation:
Answer:
i is defined as the square root of -1.
i^2 = -1
i^3 = -i
i^4 = 1
Following the pattern, we see that i^40 = 1, so i^38 is two above, or equal to -1.
So, i^38 = -1.

For the answer to the question above, asking to g<span>raph the six terms of a finite series where a1 = 5 and r = 1.25.
I'll provide the answer with the solutions below.
</span>a1 = 5
<span>a2 = 5*r = 5*(5/4) = 25/4 </span>
<span>a3 = 5*r² = 5*(5/4)² = 125/16 </span>
<span>a4 = 5*r³ = 5*(5/4)³ = 625/256 </span>
<span>a5 = 5*r⁴ = 5*(5/4)⁴ = 3125/1024
</span>I hope this helps
