Answer:
±1/30
Step-by-step explanation:
Notice that both 16 and 14400 are perfect squares; 16 = 4² and 14400 = 120².
Thus, √(16/14400) = √(4/120)² = ±4/120 = ±1/30.
This is the set of square roots of +16/14400.
The square roots of -16/14400 are ±i(1/30) (which are imaginary roots).
Answer:
Step-by-step explanation:
compare with (x-h)²+(y-k)²=r²
(x-0)²+(y-1)²=1²
h=0,k=1,r=1
center is (0,1) and radius=1
Answer:
(2,-7)
Step-by-step explanation:
Plug in the numbers to test and see if it gives you -17 and -8.
Option 1. 2(-4)+3(2)
= -8+6 = -2. Not it.
Option 2. 2(2)+3(-7)
4 - 21 = -17 Works. Try the second equation to make sure.
3(2)+2(-7)
6-14 = -8. Works.
(2,-7) is the answer.
