Answer:
18.85 mm.
7.73 mm^2.
Step-by-step explanation:
The side of the square = sqrt 36 = 6 mm.
Now this side = the diameter of the circle.
So the circumference of the circle = π * 6 = 18.85 mm.
The answer to the second part
= area of the square - area of the circle
= 36 - π *3^2
= 36 - 28.27
= 7.73 mm^2.
The improper fraction for 4 can be anything as long as when the numerator is divided by the denominator it equals 4, so for example 8/2
Answer:
t = 1.068 s
Step-by-step explanation:
given,
a(t) =- k v(t)
speed of the object decreases from 800 ft/s to 700 ft/s
distance = 1400 ft
time for deceleration = ?
a(t) =- k v(t)
integrating both side
..........(1)
since,
![1400= -\dfrac{800}{k}[e^{-kt}-e^0]](https://tex.z-dn.net/?f=1400%3D%20-%5Cdfrac%7B800%7D%7Bk%7D%5Be%5E%7B-kt%7D-e%5E0%5D)
from equation 1
![k= -\dfrac{8}{14}[\dfrac{7}{8}-1]](https://tex.z-dn.net/?f=k%3D%20-%5Cdfrac%7B8%7D%7B14%7D%5B%5Cdfrac%7B7%7D%7B8%7D-1%5D)
putting value of k in equation (1)
t = 1.068 s
Answer: A
Step-by-step explanation:
-12 is made positive so the equation is turned to 12-3 which is 9
Answer:
Step-by-step explanation:
Given
← factor both numerator and denominator
= 
← cancel common factor (1 - 2b) on numerator/denominator
= 
← cancel 6 and 3 by 3
=
