Answer:
d ≈ 14.6 units; M (2.5, 2, 6)
Step-by-step explanation:
Using the distance formula for 3-D dimensions, you get the √(213) which equals 14.6
Then, using the midpoint formula for 3-D dimensions, you find the coordinates 2.5 for x, 2 for y, and 6 for z.
Answer:
There is no possible values for the number of whole hours walking dog
Step-by-step explanation:
Let x is the number of hours working as a babysitting (x ≥ 0)
Let y is the number of hours working as a walking dogs person (y ≥0)
We have a system of inequalities:
If Joseph worked 2 hours babysitting:
2+ y ≤ 9 <=> y ≤ 7 (y > 0) and
12x + 6y ≥ 90 <=> y ≥ 11
so there is no possible values for the number of whole hours walking dogs:
Hope it will find you well.
Find an explicit formula for the arithmetic sequence -5,13,31,49,...−5,13,31,49,...minus, 5, comma, 13, comma, 31, comma, 49, co

Answer:
aₙ = a₁ + (n-1) * 18 a₁ = -5
Step-by-step explanation:
aₙ = a₁ + (n-1) * d a₁ = -5 d = 13 - (-5) = 18
a₂ = -5 + (2 - 1) * 18 = -5 + 18 = 13
a₃ = -5 + (3 - 1) * 18 = -5 + 36 = 31
a₄ = -5 + (4 - 1) * 18 = -5 + 54 = 49
