Differentiating Exponential Functions In Exercise, find the derivative of the function.

Mathematics

aleksandrvk [35]3 years ago
6 0

Answer:

Derivative of the function will be -2e^x

Step-by-step explanation:

We have given the expression y=\frac{10}{1}-2e^x=10-2e^x

We have to find the derivative of the function

So \frac{dy}{dx}=\frac{d}{dx}10-2\frac{d}{dx}e^x

We know that derivative of any constant value is 0

So \frac{dy}{dx}=\frac{d}{dx}10-2\frac{d}{dx}e^x=0-2e^x=-2e^x

So derivative of the function will be -2e^x

5y(2x-1)=y(x+2)+20, x=3​
Shkiper50 [21]

Answer:

y=1

Step-by-step explanation:

5y(2x-1)=y(x+2)+20, x=3

5y(2(3)-1)=y(3+2)+20

5y(6-1)=y(5)+20

5y(5)=5y+20

25y=5y+20

25y-5y=20

20y=20

y=20/20

y=1

mestny [16]

Answer:

The value of Mary's investment after two years = £12362.7

Step-by-step explanation:P = Principal / initial amountR = rate of interest per cent per yearT = number of yearsA = final amount at the end of T yearsThen:A = P*(1 + R/100)^2In our example:P = £12000R = 1.5 per cent per yearT = 2 yearsThus:A = 12000*(1 + 1.5/100)^2   = 12000*(1 + 0.015)^2   = 12000*(1.015)^2    = 12000*(1.030225)    = 12362.7Value of investment after two years = £12362.7
