Answer:
The distance between A and B is 13.6
Step-by-step explanation:
Distance formula=√(x2-x1)²+(y2-y1)²
Where
x1=-7
x2=6
y1=-1
y2=-5
Putting in the formula
Distance=√(6+7)²+(-5+1)²
D=√(13)²+(-4)²
D=√169+16
D=√185
D=13.6
4.76 rounded to one decimal place is 4.8
Look at the decimal place you want to round (the 7, since it is the one decimal place).
Then look at the next digit (the 6). If it is 5 or greater, round up. Otherwise, round down.
You round up the 7 up because 6 is 5 or greater.
So you get the answer 4.8
Answer:
D] f(n) = f(n − 1) + (−7)
Step-by-step explanation:
since you already know is an arithmetic series, you have to find the common difference.
87 - 94 = -7
80 - 87 = -7
73 - 80 = -7
the formula for the nth term is f(n) = f(n-1) + d
where f(n-1) is the previous term and d is the common difference, so if youu substitute you get:
f(n) = f(n-1) + d
f(n) = f(n-1) + (-7)
