Answer:
700,000
Step-by-step explanation:
okay so to increase something by 7% you have to multiply it by 1.07
so if you divide it by 1.07, you'll find the original price
749,000 ÷ 1.07 = 700,000

Step-by-step explanation:
144/16=9
Each child gets sixteen coins if there are nine children.

Answer:
y" = csc(x)[9cot²(x) - csc²(x)]
Step-by-step explanation:
Step 1: Define
y = 9csc(x)
Step 2: Find 1st derivative
y' = -9csc(x)cot(x)
Step 3: Find 2nd derivative
y" = 9csc(x)cot(x)cot(x) + -csc(x)csc²(x)
y" = 9csc(x)cot²(x) - csc³(x)
y" = csc(x)[9cot²(x) - csc²(x)]
