Distance = rate*time, or
distance = (average speed)* time, so
average speed = distance/ time.
average speed = 205 mi / (3/12) h = 205 mi/ (1/4)h = 205*4 mi/h=
= 820 mi/h
It is looks to high for speed of the truck,
probably time should be 3.12 h,
then
average speed = 205 mi / (3.12) h ≈ 65.71 mi/h.
That looks close to real life.
Answer:
Studying a foreign language improves knowledge of English and vocabulary.
Step-by-step explanation:
The intersection of the diagonals of a parallelogram is always the midpoint of each of the diagonals, which means all we have to do is grab two opposite vertices and average their coordinates.
<span>Let's use W and Y. </span>
<span>(-1 + 6)/2 = 2.5 </span>
<span>(7 + -2)/2 = 2.5 </span>
<span>So our point is (2.5,2.5) </span>
<span>We could also use X and Z. </span>
<span>(8 + -3)/2 = 2.5 </span>
<span>(7 + -2)/2 = 2.5 </span>
<span>Again, we get (2.5,2.5)</span>
Translations are transformations that change the position of the graph of a function. The general shape of the graph of a function is moved up, down, to the right or to the left. The translations are considered rigid transformations.
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
We have then:
f (x) = 2 ^ x
g (x) = f (x) + k
if k = 2
then,
the graph of g (x) is shifted vertically 2 units up
Answer:
the graph of g (x) is shifted vertically 2 units up
