Answer:
Step-by-step explanation:
Your question is unclear. What are "major intercepts"?
x²/81 + y²/64 = 1
The major axis is horizontal.
0²/81 + y²/64 = 1
y-intercepts = ±8
x²/81 + 0/64 = 1
x-intercepts = ±9
(184-94)/5=18
This means that she fills up 18 liters every minute. Thus she will be done in->
184(original amount)+(2 minutes (time passed during first data point)*18(rate of water)=184+36=220
To find the total time taken we divide 220 by 18 which is 220/18=12 2/9
Answer:
8

I dont really get the question so i thought it was 15 - 7??
Answer:
Anna's walk as a vector representation is
and refer attachment.
Step-by-step explanation:
Let the origin be the point 1 from where Ann start walking.
Ann walks 80 meters on a straight line 33° north of the east starting at point 1 as shown in figure below,
Resolving into the vectors, the vertical component will be 80Sin33° and Horizontal component will be 80Cos33° as shown in figure (2)
Ann walk as a vector representation is 
Thus, Anna's walk as a vector representation is 
To find the area to the right of a positive z-score, begin by reading off the area in the standard normal distribution table. Since the total area under the bell curve is 1, we subtract the area from the table from 1. For example, the area to the left of z = 1.02 is given in the table as .846.
