1.B - - original function is y = sqrt(x). If we make sqrt(x+4), we will move the original function to the left 4. If we make sqrt(x+4)+3, additionally the original function will be moved up 3.
2.D - original function is y = sqrt(x). If we make sqrt(x-7), we will move the original function to the right 7. If we make 5*sqrt(x-7), additionally the original function will be expanded throw the y-axis.
3.E - original function is y = x^5. If we make -x^5 (multiply x^2 by -1), we will reflect the original function over the x-axis. If we make -x^5 - 4 , we additionally will move the original function down 4.
4.C - original function is y = x^2. If we make (x-3)^2, we will move the original function to the right 3. If we make x^2 - 5 , we will move the original function down 5.
5.A - original function is y = x^2. If we multiply x^2 by 1/3, function will be compressed about the y-axis.
Answer:
4.4 L
Step-by-step explanation:
Given:
Water required for every 2 miles = 1 quart
Total distance traveled = 15 km
Now,
1 km = 0.621 miles
thus,
15 km = 0.621 × 15 = 9.32 miles
Therefore,
Quarts of water required for 15 km (9.32 miles) = 
= 4.66 quarts
also,
1 quart = 0.95 L
therefore,
4.66 quarts = 4.66 × 0.95 = 4.427 ≈ 4.4 L
Answer:
$3
Step-by-step explanation:
Martin get's $8 EVERY WEEK
So, in 5 weeks, he will get:
8 * 5 = $40
He saves up all the 5 weeks, so he has all the money.
After 5 weeks, he has:
$40
Now, he decides to buy a helmet for $37. So the amount remaining is:
40 - 37 = $3
So, Martin has $3 currently
