What does k equal if 485= 1/((k)(5.99x10^-3))

1 answer:

7 0

$k\ne 0$

$485=\frac{1}{(k)(5.99*10^{-3})}\\\\ \frac{485}{1}= \frac{1}{0.00599k}\\\\ 485*0.00599k=1\\\\ k=\frac{1}{485*0.00599}\\\\k\approx 0.3442$

Two motorcyclist A and B, started simultaneously moving towards each other. From the graph given below, find the distance each o

otez555 [7]

Answer:

Distance Covered by Motorcyclist A = 400 kilometers

Distance Covered by Motorcyclist B = 300 Kilometers

Time before they met = 5 hours

Average Speed of Motorcycle A = 80 kilometers per hour

Average Speed of Motorcycle B = 60 kilometers per hour

Step-by-step explanation:

At point t = 5 and d = 300 is their <em>meeting point</em>.

Distance Covered by Motorcyclist A = from 700 to 300 (meeting point), that is 700 - 300 = 400 kilometers

Distance Covered by Motorcyclist B = from 0 to 300 (meeting point), that is 300 - 0 = 300 kilometers

The time before they met went for 5 hours as shown in graph.

Average speed of each motorcycle is given by the slope of the line. We can figure this out easily. We have to find distance traveled per hour.

Average Speed of Motorcycle A = it went 400 km in 5 hours, so 400/5 = 80 kilometers per hour

Average Speed of Motorcycle B = it went 300 km in 5 hours, so 300/5 = 60 kilometers per hour

Find the product. 1.5m6(-2m2)4

Pani-rosa [81]

Step 1 :

Equation at the end of step 1 :

((——•(m6))•(0-2m2))•4

Step 2 :

Simplify —

Equation at the end of step 2 :

((— • m6) • -2m2) • 4

Step 3 :

Equation at the end of step 3 :

3m6

(——— • -2m2) • 4

Step 4 :

Multiplying exponential expressions :

4.1 m6 multiplied by m2 = m(6 + 2) = m8

Canceling Out :

4.2 Canceling out 2 as it appears on both sides of the fraction line

Equation at the end of step 4 :

-3m8 • 4

Step 5 :

Final result :

-12m8
