find the acceleration at the instant when the velocity is at 0
A) 2 hours 48 minutes
B) 2 hours 59 minutes
C) 3 hours 11 minutes
D) 3 hours 22 minutes
Answer:
C) 3 hours 11 minutes
Step-by-step explanation:
We are given that Jill has a hot tub that holds 1,260 gallons of water.
Draining the hot tub is modeled by the equation :
Now we are asked to find how long will it take to drain the hot tub
So, substitute y = 0 in equation :
So, it will take 3.17780580076 hours
Now 1 hour = 60 minutes
So, 0.17780580076 hours =
= minutes
≈ 11 minutes
So, it will take 3 hours and 11 minutes
Hence it will take 3 hours and 11 minutes to drain the hot tub .
The cost of 300g of potatoes and 300g of carrots varies depending on the location and the time of year. However, in general, potatoes are typically cheaper than carrots.
According to the USDA National Nutrient Database, the average price for a pound of potatoes in the United States in September 2023 was $0.62, while the average price for a pound of carrots was $0.77. This means that 300g of potatoes would cost about $0.36, while 300g of carrots would cost about $0.44.
Therefore, the difference in cost between 300g of potatoes and 300g of carrots is about $0.08.
However, it is important to note that these prices are just averages and may vary depending on the specific store or market. It is also important to keep in mind that the price of both potatoes and carrots can fluctuate throughout the year.
calculate the overall percentage increase in sales
Answer:
increase 15% = 1+(15/100)=1.15
increase 1.8% =1+(1.8/100)=1.018
evolution coefficient: 1.15*1.018=1.1707
overall percentage increase
(1.1707-1)*100=17.07%
Step-by-step explanation:
Answer:
D. 6
Step-by-step explanation:
The line of best fit represents the relation between two variables, usually indicated as x and y, where "x" is the independent variable and "y" is the dependent variable.
The general form of equation of the line of fit y = mx + b, where "m" represents the slope and b represents the y-intercept.
The given line of best fit of a scatter plot is y = 6x - 9
Now compare the given equation with the general and find the slope.
When we comparing, we get m = 6 which is the slope of the given equation.
Therefore, answer is D. 6
