3 (1 - 2v) - V = -1 (3y + 1)

Mathematics

Answer: v =  3 /7 y +  4 /7

Step-by-step explanation:

Step 1: Add -3 to both sides.

−7v+3+−3=−3y−1+−3

−7v=−3y−4

Step 2: Divide both sides by -7.

−7v /−7  =  −3y−4 /-7

v= 3 /7 y +  4 /7

What I would do first is find the base and height of the rectangle and from there you have the diameter of the circle so you can divide that by 2 and you have your radius which you’d be able to find the total area

Differentiating Functions of Other Bases In Exercise, find the derivative of the function.
aniked [119]

Answer:

\dfrac{dy}{dx} = \frac{2x-3}{\ln 16(x^2 - 3x)}

Step-by-step explanation:

We are given the following in the question:

y = \ln {16}(x^2 - 3x)

We have to find the derivative of the given expression.

y = \ln 16(x^2 - 3x)\\\text{Using the log propert}\\\\\log_a b = \dfrac{\log b}{\log a}\\\\dfrac{d(x^n)}{dx} = nx^{n-1}\\\\\dfrac{d(\log x)}{dx} = \dfrac{1}{x}\\\\\text{\bold{Differentiating we get}}\\\\\displaystyle\frac{dy}{dx} = \frac{d(\ln 16(x^2-3x))}{dx}\\\\= \frac{1}{16(x^2-3x)})\frac{d(x^2-3x)}{dx}\\\\=\frac{1}{\log 16(x^2-3x)}(2x - 3)\\\\= \frac{2x-3}{\ln 16(x^2 - 3x)}

\dfrac{dy}{dx} = \frac{2x-3}{\ln 16(x^2 - 3x)}

Solve for y when x=15<br> 4x-3y=51
Naddika [18.5K]
4x - 3y = 51, when x = 15

Plug in 15 for x.

4(15) - 3y = 51

Simplify.

60 - 3y = 51

Subtract 60 from both sides.

-3y = 51 - 60

Simplify.

-3y = -9

Divide both sides by -3.

y = -9/-3

Simplify.

y = 3

Considering the area of the right triangle, it is found that Salome used a scale factor of 1/2 to go from triangle R to triangle T.

<h3>What is the area of a right triangle?</h3>

The area of a right triangle is given by half the multiplication of the lengths of it's sides.

In this figure, we have that the sides have lengths of 4 and 5 units, hence the area is given by:

A = 0.5 x 4 x 5 = 10 square units.

The area is one fourth of the area of triangle R. Since we are dealing with an area, that works in squared units, the scale factor is given by:

S = sqrt(1/4) = 1/2.

Hence Salome used a scale factor of 1/2 to go from triangle R to triangle T.
