One solution to a quadratic function, h, is given. -4 + 7i

Which statement is true?

A. Function h has no other solutions.

B. The other solution to function h is -4 − 7i.

C. The other solution to function h is 4 − 7i.

D. The other solution to function h is 4 + 7i.

The answer isn't A. Function h has no other solutions.

I hope this helps.

B. The other solution to function is .

Step-by-step explanation:

From Algebra, we remember that quadratic functions of the form has solutions of the form:

, where both are complex if and only if .

Hence, if one solution of the quadratic function is , then the other solution is . The correct answer is B.

taxicab circle radius 9 has 4(9) = 36 points

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
