Answer:
448
Step-by-step explanation:
aₙ = a₁ + (n-1)d
a₈ = a₁ + (8-1)d = a₁ + 7d
a₁₂ = a₁ + 11d
a₈ + a₁₂ = 246 = 2a₁ + 18d a₁ + 9d = 123
a₁₀ + a₁₄ = a₁ + 9d + a₁ + 13d = 298 a₁ + 11d = 149
2d = 26
d = 13
a₁ = 6
a₃₅ = 6 + (35-1) x 13 = 448
Calculate the surface area of each candies
The vertex would be (-5, 7).
The parabola would open downwards because of the negative sign at the very beginning of the equation. If that negative sign wasn't there, it would open upwards.
Don't think clever or anything. I just used a simple graphing calculator, and most classes encourage the use of these calculators.
This equals to 2/(1/5)+(1/5)/2.
=2 x 5+1/5 x 1/2
=10+1/10
=10 1/10 <---- This is mixed fraction, since you didn't want decimals.
