The answer is: The product 4 \sqrt{7} is a radical multiplied by an integer and the result is 10.58
 By definition, the set of integers has: negative numbers, positive numbers and zero.
 Radicals are also known as roots and can be written with the symbol: \sqrt[n]{} 
 , where "n" is the index.
 Normally, when a radical is multiplied by an integer, you must simplify it, but in this case you can calculate the result by using your calculator.

Given is 4\sqrt{7}

Given is the multiplication of an integer and a radical term.

Generally, we look for the number given inside radical symbol (square-root sign) and find out if we could simplify it by finding its factors. But here we are given 7 inside square-root. 7 is a prime number, so we can use calculator and find the value of \sqrt{7}

\sqrt{7} = 2.645751311

Now we can multiply the integer number 4 with decimal number 2.645751311 to get the answer.

4 x 2.645751311 = 10.58300524

So, The product of 4 and \sqrt{7} is approximately 10.583

The sine ratio of an angle is the opposite side over the adjacent side.
Agata [3.3K]

Answer:

never

Step-by-step explanation:

In a right triangle, every angle has an opposite side and an adjacent side. And there's always a hypotenuse.

The sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse.

The tangent ratio of an angle is the opposite side over adjacent side, it is not the sine ratio of a triangle.

For example, ABC is a right angled triangle having length of the sides are a,b,c.

So

sine\ C=\frac{a}{c}

10x+9=4x -9 solve <br><br> please help
Neporo4naja [7]

Answer:

x = -3

Step-by-step explanation:

To solve this, you need to isolate the variable x, this means only one side of the equation should have the variable x. To do this, you need to do the opposite operation from what's given (if it's addition, use subraction; if it's multiplication, use division; these work vise versa)

  • Subtract 9 from both sides of the equation. This gives you 10x = 4x - 18.
  • Subtract 4x from both sides of the equation. This gives you 6x = -18.
  • Divide both sides by 6. This gives you x = -3

The final answer is x = -3
