Answer:

b

Step-by-step explanation:

complex solutions occur in conjugate pairs, hence

\sqrt{7} + 5i , then \sqrt{7} - 5i is also a solution

Answer:

Option b). the other solution to the function is \sqrt{7}-5i

Step-by-step explanation:

In a given quadratic function f(x) = ax² + bx + c, if b² - 4ac < 0 then bothe the solutions of the function will have two complex roots.

Roots of this function will be the complex conjugates.

Since one root of the equation is given as \sqrt{7}+5i

Then other solution will be its complex conjugate as \sqrt{7}-5i

Therefore, Option B) will be the answer.

If the perimeter of a square is 20, what is the length of the diagonal ?
Rina8888 [55]

Answer:

Step-by-step explanation:

if you know that the perimeter is 20,

then you have to divide by 4 to get the length of one side

20/4=5.

Draw the diagonal and write in it's length as x.

Use Pythagorean formula

Then know that a2+b2=c2

and use the two side lengths as a and b.

This gives you the equation

5^2+5^2=x^2.

Do the calculations and solve the equation.

25+25=x^2

50=x^2

√50=x.

Therefore x=√50 where x equals the length of the diagonal.
