Answer:
(a) 4.152698
(b) 3.215557
Step-by-step explanation:
(a)
n=4, so :
Each subinterval has length :
Therefore the subintervals consist of:
![[1,5], [5,9], [9,13]](https://tex.z-dn.net/?f=%5B1%2C5%5D%2C%20%5B5%2C9%5D%2C%20%5B9%2C13%5D)
Now, the midpoints of these subintervals are:
Hence:
(b)
n=4, so :
Each subinterval has length :
Therefore the subintervals consist of:
[1,5], [5,9], [9,13]
The endpoints of the subintervals consist of:
5,9
Hence:
Answer:
A: Right (90º)
B: Acute (below 90º)
C: Obtuse (above 90º)
D: Acute (below 90º)
Step-by-step explanation:
First, let's take a look at the formula to figure this out.
m = y2 - y1/x2 - x1
y2 would be -5, and y1 would be 8. -5 - 8 = -13.
x2 is -6, and x1 is also -6. -6 - -6 would be -12.
So, now we must divide -13 and -12, which results in 1 1/12.
Looking at the image of the cube you can see the outer edges would have paint on 2 sides and the corners would have paint on n3 sides.
The only ones with paint on one pace is the center cubes.
There are 6 sides to a cube and there would be 6 center pieces.
Answer: 6
So 6 is to 9
6:9
16 is to x
16:x
they are eual so change to fraction and solve
6/9=16/x
multiply both sides by x
6x/9=16
multil yboth sides y 9
6x=144
divide by 6
x=24
answer is 24 hours
