Multiply 7x13 in binary.

Mathematics
1 answer:
scoray [572]3 years ago
7 0

Answer:

1011011

Step-by-step explanation:

The binary multiplication is pretty much like the decimal one, we have just to remember that in the binary system 1+1 = 10.

First, convert 7 and 13 to binary

7 = 111

13 = 1101

now multiply with the same rules as in decimal

        1101x

          111

   --------------

         1101+

       1101  +

     1101

    1111

 -------------

   1011011

The last row of digits are the carry bits.

So 7*13 = 1101*111(binary) = 1011011 (binary)

Find the gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​
Luba_88 [7]

The gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​ is 15x²+6x-1.

<h3>What is the gradient?</h3>

A differential operator is used for a function having a vector value in three dimensions to produce a vector whose three components are the partial derivatives of the function with respect to its three variables.

The given equation for the curve is;

y = 5x³ + 3x² - x + 4​

The gradient of the tangent to the curve is;

\rm y'=\frac{dy}{dx} \\\\ y'= 5x^3 + 3x^2- x + 4 \\\\\ y'=15x^2+6x-1

Hence,the gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​ is 15x²+6x-1.

To learn more about the gradient refer to;
