Answer:

the slope I think is -6/1. because a slope is rise(-6) over run(1). negative because the line goes down

Answer:

6/-1,,,,,,= -6

Step-by-step explanation:

Rise over run. You rise(go up) 6 and you run(go left) 1, and since your going left its negative, so -6

A contaminant is leaking into a lake at a rate of R(t) = 1700e^0.06t gal/h. Enzymes that neutralize the contaminant have been ad

olasank [31]

Answer:

16,460 gallons

Step-by-step explanation:

This is a differential equation problem, we have a constant flow of contaminant into the lake, but also we know that only a fraction of that quantity of contaminant remains because of the enzymes. For that reason, the differential equation of contaminant's flow into the lake would be:

$\frac{dQ}{dt} =1700exp(0.06t)*exp(-0.32t)\\\frac{dQ}{dt} =1700exp(-0.26t)\\$

Then, we have to integrate in order to find the equation for Q(t), as the quantity of contaminant in the lake, in function of time.

$\int\limits^0_t {dQ}=\int\limits^0_t {1700exp(-0.26t)dt}\\Q(t)=\frac{1700}{-0.26} exp(-0.26t)+C \\$

Now, we use the given conditions to replace them in the equation, in order to solve for $C$

$t_{0} =0\\Q_{0}=10,000\\Q_{0}=-6538exp(-0.26*0)+C\\C=10,000+6538=16538$

Then, we reorganize the equation and we replace t for 17 hours, in order to determine the quantity of contaminant at that time:

$Q_{t} =-6538exp(-0.26t)+16538\\Q_{17} =-6538exp(-0.26*17)+16538\\Q_{17} =16460 gallons$

The Hu family goes out for lunch, and the price of the meal was $48. The sales tax on the meal is 7%, and the family also leaves

mr Goodwill [35]

Answer:

The total cost of the meal is $58.56.

Step-by-step explanation:

The question is asking for problem solving with percentages. In order to multiply by a percentage, we must first convert the percentage to a decimal by diving the percent by 100. Since the Hu family is going to leave a 15% tip on the pre-tax amount of $48, we will need to multiply 48 x .15 = $7.20. The Hu family must also pay a 7% sales tax on the cost of the meal. In order to find the cost of the meal, including tax, we take the price of 48 x 1.07 = $51.36, which would be the original cost plus an additional 7% tax. Lastly, we would need to include the tip to the post-tax total: $51.36 + $7.20 = $58.56.
