Step-by-step explanation:
I got it right so this should help
if you want the explanation i can give that to u just comment
Opposite/adjacent= cosine
cos B= opp/adj
cosB= 7/12
B=cos^-1 (7/12)
(Type it into a graphing calculator)
B=54.3 degrees
Make sure your calculator is in degree mode and you use the inverse cosine.

Answer:
Wasim has enough money.
Step-by-step explanation:
1. find the area of the garden path:
600 cm x 120 cm = 72,000 sq. cm
2. find the area of each stone:
it is a square of 30 cm by 30 cm, so:
30 cm x 30 cm = 900 sq. cm
3. find how many stones can fit in the path:
72,000 / 900 = 80 stones
4. multiply that by the price of each stone:
80 stones x $2.50 = $200
Wasim's budget is $220 and the stones will only cost $200, so it is within the budget
Average rate of change over an interval =
(difference in value of the function between the
beginning and end of the interval)
divided by
(length of the interval).
Example:
If the function was 200 pounds at the beginning, and 98 pounds 3 hours later,
then the average rate of change is (98 - 200) / 3 = -34 pounds per hour.
