Note the squares... 13 is possible because it is a sum of two squares (integers) 9 + 4 .. use (0,3) & (2,0) ... get the square roots and place on different coordinate axes... for a simpler value. but there is none for 15... there is one for 18 ... 18 = 3^2 + 3^2 ... try (0,3) ,(3,0) , (3,6), (6,3).

Calculate dy/dx when y = (x2 + 2)e 4x as the derivative of a product, letting u = x2 + 2 and v = e4x . Which of the following is
Vera_Pavlovna [14]

Answer:

D. du/dx = 2x

Step-by-step explanation:

Given to find dy/dx where;

y=(x^{2} +2)e^4^x

Then when you let;

u=x²+2    and

v=e^{4x}

Then

In  u=x²+2  du/dx = 2x------------------------step 1

In e^4x, dv/dx = e^4x * d/dx (4x)

=e^4x *4 = 4e^4x------------------------------------step 2

I need some help with this question.

The scale factor will be 1.5. The corresponding angles are congruent because the size is changed not the angles.

<h3>What is dilation?</h3>

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

Adnan wants a larger garden.

He draws the triangle ΔPQR to show his original garden.

He wants to enlarge a garden, so he uses a dilation to form the image of the triangle ΔPQ'R'.

He uses vertex P as the center of the dilation.

The ratio of the corresponding sides will be given as

PQ'/PQ = Q'R'/QR = R'P/RP = 1.5

The scale factor will be 1.5.

The corresponding angles are congruent because the size is changed not the angles.

More about the dilation link is given below.
