Answer:
b 1/4 (n-64)
Step-by-step explanation:
Multiplying the expression by 1 does not change its value:
= (1/4)(4) × (1/4n -16)
= (1/4) × (4(1/4n -16)) . . . . . associative property
= (1/4) × ((4/4)n -4·16) . . . . distributive property
= (1/4)(n -64) . . . . matches choice B
Answer:
16.26
Step-by-step explanation:
I am not completely sure what the problem is asking, but I believe that you are just supposed to take the inverse of sine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then sine. You use the inverse of sine when two sides are given, but you are not given the angle.
It should look like:
, which is approximately 16.26.
Hopefully this is right, if not, please let me know. Good luck.
√12500 = √(125 × 100) = √125 * √100
√125 * √100 = √(5 × 5 × 5) * √(10 × 10)
= 5√5 * 10
= (5*10)√ 5 = 50√5
√12500 = 50√5 ≈ 111.803
