11/8 is 1.375 that times 12 is 16.5 so 16.5 dollars
Problem 1)
The base of the exponential is 12 which is also the base of the log as well. The only answer choice that has this is choice B.
======================================================================
Problem 2)
log(x) + log(y) - 2log(z)
log(x) + log(y) - log(z^2)
log(x*y) - log(z^2)
log[(x*y)/(z^2)]
Answer is choice D
======================================================================
Problem 3)
log[21/(x^2)]
log(21) - log(x^2)
log(21) - 2*log(x)
This matches with choice B
======================================================================
Problem 4)
Ln(63) = Ln(z) + Ln(7)
Ln(63)-Ln(7) = Ln(z)
Ln(63/7) = Ln(z)
Ln(9) = Ln(z)
z = 9
======================================================================
Problem 5)
Ln(5x-3) = 2
5x-3 = e^2
5x = e^2+3
x = (e^2+3)/5
This means choice A is the answer
Hi there!
To find your answer, simply sub in the point and the slope into y-y1=m(x-x1) for y1, x1 and m!
m=-8
point: (1,-8) use this point for x1 and y1
y+8=-8(x-1)
Therefore your equation is y+8=-8(x-1)
Hope this helps!
Answer:
yes
Step-by-step explanation:
Answer:
600 seconds
Step-by-step explanation:
In this case we have to calculate the speed;
Speed = Distance/Time
Speed = 100/20 = 5 mph
Next to get our answer we have to calculate the amount of time
Time = Distance/Speed
Time = 3000/5 = 600 seconds
