The sequence is an geometric progression;
Nth=a₁r^(n-1)
a₁ is the first term=-1
r=ratio=a₂/a₁=6/-1=-6
Nth=-1(-6^(n-1)
NTh=an
a₁=-1(-6⁰)=-1
a₂=-1(-6¹)=6
a₃=-1(-6²)=-36
a₄=-1(-6³)=216
therefore this serie is rising at an increasing fast speed, it is an geometric progression.
Answer:
Part A: 480 ounces of water are left in the water tank.
Part B: he will drink 3 tanks of water in 30 days.
Step-by-step explanation:
Part A:
5x8x16 = 6x16 = 1/2x8x16
=640 = 96 = 64
=480
Part B:
4x30 divided by (5x8) = 120 divided by 40 = 3

1) A figure formed by line segments only is called a <u>polygon</u><u> </u> .
2) Perimeter of a regular polygon is <u>Number </u><u>of </u><u>sides </u><u>×</u><u> </u><u>Measure </u><u>of </u><u>each </u><u>side </u><u>.</u>
3) Perimeter of a irregular polygon is <u>sum </u><u>of </u><u>all </u><u>sides </u><u>.</u>
4) Two circles with same centre but different radii is called <u>Concentric </u><u>circles</u><u>.</u>
5) Ratio of circumference of circle to its diameter is <u>pie </u> and is named by Greek letter <u>π </u>.
6) Distance around the circle is called<u> </u><u>circumference</u><u>.</u>
7) A chord of the circle contains exactly <u>two points</u> on a circle.
8) 1 hectare = <u>1</u><u>0</u><u>,</u><u>0</u><u>0</u><u>0</u><u> </u><u>m²</u>

Answer:
x=5
Step-by-step explanation:
I was working on this problem also.
Maybe my version will help, too.
You need to sketch f given the information you have.
f'(x) is approximately a a cubic polynomial which means f will look like a quartic (think W)
f slopes down (negative slope) to x=2 and then slopes down again...this is a horizontal tangent.
f then slopes down to to x=5 where is has a minimum and then slopes up.
