In which step did the student first make an error?
Answer: Step 2
Step 2 should be:
−3y = -45 + 6z
Step-by-step explanation:
it seems we are dealing with subtraction, as the differences between the 1st and second, and between the 2nd and 3rd numbers are equal : -7
so, we can assume that the sequence is created by always subtracting 7.
a1 = 352
a2 = a1 - 7 = 352 - 7 = 345
a3 = a2 - 7 = a1 - 7 - 7 = 352 - 7 - 7 = 338
an = an-1 - 7 = a1 - 7(n-1) = 352 - 7(n-1)
a43 = 352 - 7(43-1) = 352 - 7×42 = 352 - 294 = 58
The answer is 5% I’m pretty sure. I just subtracted $40-$30 :)
Answer:
156 ft
Step-by-step explanation:
Put 8 where t is, and do the arithmetic.
-16·8² +1180 = -1024 +1180 = 156
The height of the object at 8 seconds is 156 feet.
