Write 2 different equations with a sum of 9/5.
Julli [10]
Two possible equations are:

\dfrac{5}{5} +   \dfrac{4}{5}   = \dfrac{9}{5}

\dfrac{2}{5} +   \dfrac{7}{5}   = \dfrac{9}{5}

How would you explain to a friend , the process for finding the total surface area of a cylinder using the net of a cylinder?
Artemon [7]

The toal surface area of a cylinder is 2πrh+2πr²

Step-by-step explanation:

The "net" of any geometrical shape refers to the two-dimensional equivalents of the three-dimensional object.  

e.g. geometrical net of a cylinder would consist of two circles (one each at top and bottom) and a rectangle extending from bottom to the top in a curvilinear manner.

Hence, the Total surface area (TSA) of the cylinder can be found

by considering cylinder to be made of three parts

  • the circle at the bottom
  • the circular tube which extends for height "h" of the cylinder
  • the circle at the top (considering it is closed cylinder)

The surface area of a circle (for 2-dimensional figures surface area is the same as area since the thickness factor is 1)= πr²

Since there are two circles= surface area (combined)= 2πr²

Moreover, this circle extends to height h. Hence, the combined surface area of the circle extending to height h (int he forms of the tube)= circumference*height= 2πrh

hence TSA= 2πrh+ 2πr²

Given f''(x) = - 16 sin(4x) and f'(0) = - 4 and f(0) = - 2.<br><br> Findf(1) =
cestrela7 [59]

Answer:

The complete equation is f(x) = \sin 4x -8\cdot x -2. f(1) = -10.756

Step-by-step explanation:

Let be f''(x) = -16\cdot \sin 4x, we need to determine the formula of f(x) by integrating twice:

f'(x) = \int {(-16\cdot \sin 4x)} \, dx

f'(x) = -16\int {\sin 4x} \, dx

We apply the following algebraic substitution in expression above:

u = 4\cdot x and du = 4\,dx

f'(u) = -4\int {\sin u} \, du

f'(u) = 4\cdot \cos u + C_{1}

f'(x) = 4\cdot \cos 4x + C_{1}

We use the same approach to determine f(x):

f(x) = \int {(4\cdot \cos 4x)} \, dx + \int {C_{1}} \, dx

f(u, x) = \int {\cos u} \, du + C_{1}\int \, dx

f(u,x) = \sin u + C_{1}\cdot x + C_{2}

f(x) = \sin 4x + C_{1}\cdot x + C_{2}

If we know that f'(0) = -4 and f(0) = -2, the integration constants are obtained below:

4 + C_{1} = -4

C_{1} = -8

C_{2} = -2

The complete equation is f(x) = \sin 4x -8\cdot x -2. (Angles are measured in radians) Then:

f(1) = \sin 4 - 8- 2

f(1) = -0.756-8-2

f(1) = -10.756
