Answer:
2
Step-by-step explanation:
a₃ = -2
a₇ = -10
The nth term of an arithmetic sequence is:
a = a₁ + d (n − 1)
Therefore:
-2 = a₁ + d (3 − 1) = a₁ + 2d
-10 = a₁ + d (7 − 1) = a₁ + 6d
Subtract the equations:
8 = -4d
d = -2
Plug into either equation to find the first term.
-2 = a₁ + 2(-2)
a₁ = 2
The formula for area of a square is Area = side^2.
You are given the area, so now you have 97,818 = Side^2.
To find Side, take the square root of both sides:
Side = √97818
Side = 312.76 miles.
Rounded to the nearest mile is 313 miles.
I think it’s 3 because it’s just how I think it is I’m probably not correct but I think it’s 3
Answer:
(-2,-6)
-2
Step-by-step explanation:
To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have
-2
this is the x coordinate of the vertex.
Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)
This is the y coordinate
which means we have (-2,-6)
the axis of symmetry is just the x coordinate of the graph
which is -2
Answer:
$ 322
Step-by-step explanation:
x = his paycheck
x - 1/2x + 55 = 216
1/2x + 55 = 216
1/2x = 216 - 55
1/2x = 161
x = 161 * 2
x = $ 322 <===
