You want the (positive) distance when the height is 0, 0= -d^2 + 10d +5.
You would factor that out(You'd get radicals), and the final answer would be
<span>5±<span>30<span>−−</span>√</span></span><span>
You'd take the only positive one of the two, 5 + srt(30)
I hope I did that right :/</span>
The K-constant variation is the factor of the increase-decrease relationship between the x-variable and y-variable which can be stated as y=k*x or x=y/k<span>. For example, if y variable equal 5 and the x variable equal 2 then the k-constant variation equal 2 (calculation y=k*x --> 5=2*2.5). This constant shows the relationship between the variables.</span>
Distance traveled in the first hour = 50 miles
Distance traveled in the second hour = 72 miles
Distance traveled in the third hour = 46 miles
Total distance = 50 + 72 + 46 = 168 miles
23 miles = 1 gallon
168 ÷ 23 = 7.30 gallons (nearest hundredth)
Answer: 7.30 gallons
Answer:
Step-by-step explanation:
50,000 mm=5,000 cm=500 decimeter=50 m=5 decameter
so both are equal.
Answer:
y = -1x + 1
