A Comment "If i know the measures of angles C and B, I can find the measures of A and D" is TRUE
Explanation :
If we know angles C and B we can find angles A and D as,
As from figure we know
A+B = 180°
∴ A = 180° - B ... we know B so we get A
Also,
B+C+D = 180° ... as BCD is a triangle
∴ D = 180° - (B+C) ... we know B and C so we get D
Answer:
s = 6 m
Step-by-step explanation:
The value of the velocity v is given as:
m/s
To find s, we have to integrate and apply the initial values of s = o when t = 0:
![\frac{ds}{dt} = 6 sin(2t)\\\\\int\limits^s_0 {ds} = \int\limits^t_0 {6sin(2t)} \, dt\\\\s|^s_o = -3cos(2t)|^t_o\\\\s - 0 = -3cos(2t) -(-3cos(0))\\\\s = -3cos(2t) + 3(1)\\\\s = -3cos(2t) + 3](https://tex.z-dn.net/?f=%5Cfrac%7Bds%7D%7Bdt%7D%20%3D%206%20sin%282t%29%5C%5C%5C%5C%5Cint%5Climits%5Es_0%20%7Bds%7D%20%3D%20%5Cint%5Climits%5Et_0%20%7B6sin%282t%29%7D%20%5C%2C%20dt%5C%5C%5C%5Cs%7C%5Es_o%20%3D%20-3cos%282t%29%7C%5Et_o%5C%5C%5C%5Cs%20-%200%20%3D%20-3cos%282t%29%20-%28-3cos%280%29%29%5C%5C%5C%5Cs%20%3D%20-3cos%282t%29%20%2B%203%281%29%5C%5C%5C%5Cs%20%3D%20-3cos%282t%29%20%2B%203)
When t = π/2, s will be:
s = -3cos(2 * π/2) + 3
s = -3cos(π) + 3
s = -3(-1) + 3
s = 3 + 3
s = 6 m
Answer:
6x - 12
Step-by-step explanation:
6(x-2) => (6 · x) - (6 x 2) => 6x - 12
Y=2x because if u divide 14 by 7 u get 2.
I think it’s the dime. A quarter. And 3 nickels.
10 + 25 +5+5+5 = 50
