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.

What are all the exact solutions of 2 sin^2 x- sin x = 0
alexandr1967 [171]
Factor:

2sin^2x-sinx = 0

sinx(2sinx - 1) = 0

Therefore the solutions are when:

sin x = 0
And
sinx = 1/2

So sinx = 0
is true when x = 0 and pi  and all the angles coterminal with these points.  Thus, the answer is x = pi*n, (where n is some integer)

sinx = 1/2
is true when x = pi/6 and 5pi/6 and the angles coterminal with these points.
Thus, the answer is x = pi/6 + 2pi*n (where n is some integer)
and x = 5pi/6 + 2pi*n (where n is some integer)

The original price of a stove is $570.00. If it has a 25% discount, find the selling price. *
Rom4ik [11]

Answer:

$357.50

Step-by-step explanation:

25%×570.00

(25/100)×570.00

= $142.50

S.P= O.P-D.P

= (570.00-142.50)$

= $357.5
