What units are used to measure both velocity and speed
mylen [45]

Answer:

Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second.  I hope that this is useful information.

Solve: 12^x2+5x-4 = 12^2x+6<br> x=2<br>x = -5<br>x=2x=-5<br>no solution​
omeli [17]

Answer:

x=2

Step-by-step explanation:

12x^2+5x-4 = 12x^2+6

Subtract 12x^2 from each side

12^x2-12x^2+5x-4 = 12^2x-12x^2+6

5x-4 = 6

Add 4 to each side

5x-4+4 = 6+4

5x = 10

Divide each side by 5

5x/5 = 10/5

x = 2

What is the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4?
ruslelena [56]
X) = 3 ln(x)

g(x=2) = 3 ln(2)
g(x=4) = 3 ln(4) = 3 ln(22) = 6 ln2

We have two ordered pairs:

(x,3 ln(2)) and (4,6 ln(2))

The average rate of change is the slope (m) of the secant line connecting the two points:

m = (6 ln2 - 3 ln2)/(4-2) = 3ln(2)/2 ≅ 1.04
