ratio of perimeter is the same as ratio of sides so perimeter would be 1:4

since area is in square units you need to square the ratio (1:4)^2 which is 1:16

In Exercise, find the derivative of the function.<br> y = e5x
mariarad [96]

Answer: The derivative of the function y=e^{5x} is 5e^{5x} .

Step-by-step explanation:

We know that the derivative of e^{ax} with respect to x is given by :

\dfrac{d}{dx}(e^{ax})= a e^{x}    (1)

The given function is y=e^{5x}

Differential both sides with respect to x , we get

\dfrac{dy}{dx}=\dfrac{d}{dx}(e^{5x})

\Rightarrow\ \dfrac{dy}{dx}=5e^{5x} ( Using (1))

Therefore , the derivative of the function y=e^{5x} is 5e^{5x} .

For Problems 9-10, simplify the expressions using properties of operations. 9. (4x – 7.2) + (-5.3x-8) 10. (t - 1) – (-7t + 2)
mafiozo [28]

The given expression is : (4x – 7.2) + (-5.3x-8)

Simplify :

Open the brackets :

(4x – 7.2) + (-5.3x-8) = 4x - 7.2 - 5.3x - 8

Arrange the variable and constant terms together :

(4x – 7.2) + (-5.3x-8) = 4x - 5.3x - 8 - 7.2

Solve the variable and constant terms together :

(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2

Since, the variable and constant term can not solve together so the above equation is the simplest form:

(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2

Answer : (4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
