Answer:
you have to find only one example in which the conjecture is not true.
450. To find the rate you would do 1800 divided by 4 which is the hours without wind. 1800/4 =450
the vertex form is (x+2)^2 - 9 and the vertex is (-2, -9)
Answer:A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
Step-by-step explanation:
Sin (2 pi/3) = sqrt(3)/2
you can get this from the unit circle
