Answer:
We conclude that he have 84 possible complete trips to Tech.
Step-by-step explanation:
We know that he live 9 (rectangular) blocks from Tech. The trip is 3 blocks north and 6 blocks west. We calculate number of possible complete trips to Tech. We know that
We calculate
We conclude that he have 84 possible complete trips to Tech.
Answer:
a₁₅₇ = 1,088
Step-by-step explanation:
aₙ = a₁ + d(n-1); where 'd' if common difference
a₁₅₇ = -4 + 7(156)
= -4 + 1092
= 1,088
Answer:
y = -2x^2 -4x +5
Step-by-step explanation:
The vertex is at (-1,7) and the y intercept is at (0,5)
The vertex form of a parabola is
y = a(x-h)^2 +k
where (h,k) is the vertex
y = a(x--1)^2 +7
Then substitute the point into the equation
y = a(x+1)^2 +7
5 = a(0+1)^2 +7 +7
Subtract 7 from each side
5-7 = a(1)^2
-2 = a
y = -2(x+1)^2 +7
Now FOIL
y = -2 (x^2 +2x+1) +7
Then distribute
y = -2x^2 -4x-2 +7
y = -2x^2 -4x +5
45 is the new mean. If u add 5 to each, then u will gat 40, 50, 60, and 30. Add all of the, up, and divide by 4. U get 180/4, which is 45.
