Answer:
uₙ₊₁ = uₙ + ¹/₂
Step-by-step explanation:
uₙ₊₁ = uₙ + d
u₈ = 3
u₁₀₀ = 49
We can establish the following:
u₉ = 3 + d
u₁₀ = (3 + d) + d = 3 + 2d
u₁₁ = (3 + 2d) + d = 3 + 3d
so...
u₈₊ₐ = 3 + ad
u₁₀₀ = u₈₊₉₂ = 3 + 92d
3 + 92d = 49
92d = 46
d = ¹/₂
∴ uₙ₊₁ = uₙ + ¹/₂
Answer: 4
Step-by-step explanation:
If you made $7 an hour and worked for 40 hours, every day for a year, you would make $14,560 a year and about $1,213.33 a month.
Because 7 x 40 = 280 (which is how much money you make a week.)
And 280 x 52 = 14,560 (because you would work for 52 weeks).
I hope this helped! Good luck and have a great night!
Answer:
x = 30°
Step-by-step explanation:
Since 2 of the sides are congruent then the triangle is isosceles and the 2 base angles are congruent, both 75°
The sum of the 3 angles in a triangle = 180°, then
x = 180° - (75 + 75)° = 180° - 150° = 30°
