jeyben [28]

Answer:

Step-by-step explanation:

A) What is the speed of the pedestrian BC, CD, and DE?

Speed from B to C = distance/time = (40 - 20) / 4 = 20/4

= 5 km/h

Speed from C to D = distance/time = 0 / 2

= 0 km/h

Speed from D to E = distance/time = (20 - 0) / (10 - 6) = 20/4

= 5 km/h

B) After what time since the stop did he arrive at point E?

Since the stop at D, he arrived at E after (10 - 6) = 4 h

C) Write the formulas for function d(t) for sections BC, CD, and DE

For BC, d = 40 when t = 0 and d = 20 when t = 4

So d(t) = 40 - 5t

For CD, d = 20 when t = 4 and t = 6

So d(t) = 20

For DE, d = 20 when t = 6 and d = 0 when t = 10

So d(t) = 5 * (10 - t) or d(t) = 50 - 5t

How do I Express 18+24 as the product of the GCF and another sum

svp [43]

Answer:

$6(3+4)$

Step-by-step explanation:

We are asked to represent $18+24$ as the product of the GCF and another sum.

First of all, we will find the greatest common factor of 18 and 24.

Factors of 18: 1, 2, 3, 6, 9, 18.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.

We can see that greatest common factor of 18 and 24 is 6. Let us write our given expression as product.

$6\cdot 3+6\cdot 4$

Factor our 6:

$6(3+4)$

Therefore, our required expression would be $6(3+4)$ .
