Answer:
m = 9
Step-by-step explanation:
The slope of a line can be found through rise-over-run: dividing the change in y-coordinate over the change in x-coordinate -- (y₁ - y₂) ÷ (x₁ - x₂)
That looks like this: (-2 - 7) ÷ (-7 + 6) --> subtracting negative = adding positive
Add: -9 ÷ -1
Divide: 9
150/75 = 2 hours
150/60 = 2.5 hours
150/50 = 3 hours
150/20 = 7.5 hours
Answer:
The area is 12.56, and the circumference is 12.56.
Step-by-step explanation:
For the area,
We need to use the formula A=3.14*radius*radius
So we plug it in, and we get 3.14*2*2, which is 12.56 centimeters squared.
For circumference, we need to do,
C = 3.14*diameter
To find the diameter we need to do 2 (radius) x 2 which is 4
Plugging it in that would be 3.14 * 4 which is 12.56
So, in this case, the area is 12.56, and the circumference is also 12.56.
Answer:
Angle is 37.21 degree
Step-by-step explanation:
Given Data
|A|=2.93
|B|=3.00
A×B=-4.95k+1.94i
Angle=?
Solution
|A×B|=|A|×|B|Sinα
First for |A×B|
|A×B|=
|A×B|=
|A×B|=5.316
|A×B|=|A|×|B|Sinα
Sinα=
Sinα=
α=37.21 degree
