Since this is a right triangle, we could use the pythagorean theorem: a²+b²=c² where this problem already gave us a=10 and b=√60, and we want to solve for c.
10²+(√60)²=c² ← 10² is 100, and the square cancels out the square root on the 60
100 + 60 = c²
160 = c² ← To isolate c, we take the square root of both sides
√160 = c ← √160 is the same as 4√10
Answer: 4√10

Answer: 5808000 ways
Step-by-step explanation:
When it comes to selection, the combination formula is used to calculate the number of ways an item can be selected.
Using the combination formula of picking "r" items from a total of "n" items, the number of ways become:
nCr = n! /(n-r)! × r!
Hence,
to choose 3 different beverages from possible 12 = 12C3 = 220
to choose 3 different appetizers from possible 12 = 12C3 = 220
to choose 3 different deserts from possible 10 = 10C3 =120
Total number of ways to choose this meal = 220 × 220× 120 = 5808000 ways
Answer:
y = 1/3(x-5)
Step-by-step explanation:
To find the inverse of a function switch the x and y and then solve for y.
x = 3y + 5
x-5 = 3y
(x-5)/3 = y
Or
y = 1/3(x-5)
