$i=\sqrt{-1}$

$5\sqrt{-54}=5\sqrt{9(-6)}=5\cdot\sqrt9\cdot\sqrt{-6}=5(3)\sqrt{(6)(-1)}\\\\=15\cdot\sqrt6\cdot\sqrt{-1}=15\cdot\sqrt6\cdot i=15i\sqrt6$

Answer:

your answer is correct for the reason you state

Step-by-step explanation:

A one-to-one function must pass the horizontal line test: no horizontal line intersects the graph at more than one place.

Here, the horizontal line y=3 intersects at x=1 and x=2, so the test fails.

Carter used 1 1/3 gallons of paint to paint 2/5 of a wall. How many gallons will it take to paint the whole wall? Show your reas

fgiga [73]

Answer:

3 1/3 gallons

Step-by-step explanation:

It is more helpful to think of the wall as 5 sections. if two sections used 4/3, by logic one section uses 2/3 (because 4/3 ÷ 2 = 2/3). since there are 5 sections, 2/3 × 5 you get 10/3. turn it into a mixed fraction and you get 3 1/3.
