A van is travelling due east at a speed of 28 miles per hour. If the van started off 154 miles directly north of the city of Smithville, how fast is the distance between the van and Smithville changing when the van has travelled 38 miles

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
