Answer:
1 day 21 hours 40 minutes
Step-by-step explanation:
5 days 6 hours 20 minutes
- 3 days 8 hours 40 minutes
============================
We will need to borrow minutes from the hours because we don't have enough.
1 hour = 60 minutes
6-1 = 5 hours
20 +60 = 80 minutes
5 days 5 hours 80 minutes
- 3 days 8 hours 40 minutes
==========================
We will need to borrow hours from the days because we don't have enough.
1 day = 24 hours
5 -1 =4 days
5 + 24 = 29 hours
4 days 29 hours 80 minutes
- 3 days 8 hours 40 minutes
==========================
1 day 21 hours 40 minutes
The magnitude of each vector is the Pythagorean sum of its components.
a. |v1| = √(2² + (-6)²) = √40 = 2√10
|v2| = √((-4)² + 7²) = √65
b. To make each vector into a unit vector, divide each component by the vector's magnitude.
u1 = v1/|v1| = (2/(2√10), -6/(2√10))
u1 = (√10/10, -3√10/10)
u2 = v2/|v2| = (-4/√65, 7/√65)
u2 = (-4√65/65, 7√65/65)
Answer:
x= 0
Step-by-step explanation:
Let's first simplify the equation to make the PEMDAS process easier.
8x-10=3x-10+7x
8x-10=10x-10
Now lets start the subtracting and dividing process.
8x=10x
0=2x
0=x
Answer: Letter Choice, (B) ====> 4,256 pi cm^2
Step-by-step explanation:
<u>Formula: Surface Area of Cylinder = (2pi ) (r^2 ) + 2pi (r) (h)</u>
<u>Showing Work:</u>
<u>Radius of the Base ===> 28cm</u>
<u>Height =====> 48cm </u>
(2pi ) (r^2) + 2pi (28)(48)
2 (pi) (r^2) + (circumference) (height)
2( pi) (r^2 + 2)( pi)(r)(h)
2 pi * (2) (r^2 + (2)(r)(h)
2pi * (r^2 + rh)
2(r)(pi)(r + h)
2( 28)(pi)(28 + 48)
56(pi)(76)
4256(pi)^2
<u>Therefore, Your Answer ======> Letter Choice; (B) ======> 4,256pi cm^2</u>
Hope that helps!!!!! : )
