Mathematics

Answer:

y = -x + 2

Step-by-step explanation:

The equation of line is often written in the form;

     y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

 From the given parameters;

        c  = 2

     (1,1) are the coordinates

Let us find the slope of the line;

      1  = m(1) + 2

       1  = m + 2

          m = 1- 2  = -1

The equation of the line is;

         y  = -1x + 2

         y = -x + 2

What is the surface area of a cylinder with the given dimensions?
pogonyaev

Answer:

The surface area of a cylinder with the given dimensions is 571.48 cm^2.

Step-by-step explanation:

To find the surface area, you need to use the formula 2\pi r^2 + h * 2\pi r where r represents the radius and h represents the height. In this problem, the expression would be 7^2 * 3.14 * 2 + 3.14*14*6 = 49 * 6.28 + 3.14 * 84 = 307.72+263.76 = 571.48 cm^2.

Write an equation that can be used to answer the question. Then solve. Round to the nearest tenth if necessary. ​
tensa zangetsu [6.8K]

Answer:

5^2+h^2=12^2, the answer would be ~10.97 ft.

Step-by-step explanation:

I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.

Pythagorean theorem is :

a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.

Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.
