Answer:
t = -24*log(2/3)
Step-by-step explanation:
The expression is:
V = 22,500*10^(-t/12)
Replacing with V = 10,000 and isolating t, we get:
10,000 = 22,500*10^(-t/12)
10,000/22,500 = 10^(-t/12)
4/9 = 10^(-t/12)
(2/3)² = 10^(-t/12)
2*log(2/3) = -t/12
-12*2*log(2/3) = t
t = -24*log(2/3)

Answer:
<u>1st graph</u>:
Slope-intercept is y = -7/2x + 3
Point Slope is y + 4 = -7/2(x - 2)
Standard is 7x + 2y = 6
<u>2nd graph</u>:
Slope-intercept is y = 1/2x - 4
Point Slope is y + 2 = 1/2(x - 4)
Standard is x - 2y = 8
<u>3rd graph</u>:
Slope-intercept is y = 3x - 3
Point Slope is y - 3 = 3(x - 2)
Standard is 3x - y = 3
<u>4th graph</u>:
Slope-intercept is y = -2/7x - 4
Point Slope is y + 2 = -2/7(x + 7)
Standard is 2x + 7y = - 28

Sorry this took a while, I was doing other stuff for school. I also had to relearn point slope for this, so it took me some time to figure it out. Hope this helps though :)
Answer:
A = 15Km/hour B = 0Km/Hour C = 60Km/Hour D = 40/Hour
Step-by-step explanation:
To find speed, the equation is distance / time. So, for a, the distance travelled in 2 hours was 30 Km. To make it a unit number, I divided the 30 / 2 and got 15Km/Hour.
For B, there was no distance travelled. So the velocity would be 0.
For C, the distance travelled in half an hour was 30 Km. So the speed would be 60 Km/ Hour.
For D, the distance travelled in 1.5 hours was 60Km. The distance travelled in 1 hour was 40 Km. So the speed would be 40Km/Hour.
