Answer:
Step-by-step explanation:
<u>Given recursive formula:</u>
- a₁ = -1
- aₙ = - 3aₙ₋₁ + 6 for n ≥ 2
<u>The first 4 terms are:</u>
- a₁ = - 1, given
- a₂ = - 3*(-1) + 6 = 3 + 6 = 9
- a₃ = - 3*(9) + 6 = - 27 + 6 = - 21
- a₄ = - 3*(-21) + 6 = 63 + 6 = 69
Answer:
3) 162 ft² || 4) 38.25 mm²
Step-by-step explanation:
3)
area of triangle = 0.5 * base * height
= 0.5 * 27 * 12
= 162 ft²
4) area of triangle = 0.5 * base * height
= 0.5 * 8.5 * 9
= 38.25 mm²
Answer:
The answer is 17 and no
Step-by-step explanation:
#11 The room is a cube so...
cube root the volume 4913
³√4913=17
The length of the room is 17 feet.
#12
Square root 121
√121=11
Since the car is 13 feet the car will not fit in the garage which is 11ft.
So here are your variables:
# of adult tickets= x
# of student tickets 2x
so x+2x= 246 and solve
3x=246
x=82 adult tickets were sold
