Answer:
C, 105 Degrees
Step-by-step explanation:
So the two opposite sides of a parallelogram is equal to each other and the two adjacent angles are supplementary. So if (x+40)+3x=180, this means that 4x+40=180. This gives us 4x=140, so x=35. If we plug it back into the equation it ascertains as such: 3(35)= 105. The answer for this question and angle O is 105 degrees, or C.
Answer:
D)
Step-by-step explanation:
for each equation, substitute zero for 'x' and solve for 'y' (this will be the y-int)
A) y-int = 2
B) y-int = 0
C) y-int = 1
D) y-int = 1.5
Answer:
67.3°C
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt


When raised to the third power, it is the number times itself three times.
-2(-2) = 4
4(-2) = -8
