Answer:

the table does represent a propor. rela. since y=12x

you can multiply the x values by 12 and that y value will be just that, and in this case, all of them are multiplied by 12.

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$\displaystyle y = \frac{3}{2x^2}$

$\displaystyle \text{Point} \ (1, \frac{3}{2})$

Step 2: Differentiate

[Function] Rewrite [Exponential Rule - Rewrite]: $\displaystyle y = \frac{3}{2}x^{-2}$
Basic Power Rule: $\displaystyle y' = -2 \cdot \frac{3}{2}x^{-2 - 1}$
Simplify: $\displaystyle y' = -3x^{-3}$
Rewrite [Exponential Rule - Rewrite]: $\displaystyle y' = \frac{-3}{x^3}$

Step 3: Solve

Substitute in coordinate [Derivative]: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1^3}$
Evaluate exponents: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1}$
Divide: $\displaystyle y'(1, \frac{3}{2}) = -3$

No work needed, just need answer please.

In-s [12.5K]

Answer:

1 is 27.8%

2 is 41.7%

Step-by-step explanation:

To calculate 1 there is a 10/36 chance (2, 3, 4, 5 out of possible roles of 2 - 12)

To calculate 2 there is a 15/36 chance (2, 3, 5, 7, 11 are prime)

How can you actually divide numbers without subtraction?

Tamiku [17]

#include <stdio.h> #include <stdlib.h>

// Function to perform division (x / y) of two numbers x and y. // without using division operator in the code. int divide(int x, int y)

{ // handle divisibility by 0. if (y == 0)

{ printf("Error!! Divisible by 0"); exit(1);

} // store sign of the result.

int sign = 1; if (x * y < 0)
