Answer:

1. a = 5, b = 8

2. d = 2

Step-by-step explanation:

1. The sum of adjacent angle is 180 degree

115 + 8b +1 = 180

8b = 180 -116

b = 8

Similarly

14a - 5 + 115 = 180

14a = 180 -110

14a = 70

a = 14

2. Intersecting diagonals divide each other into equal halves

3d + 5 = 5d + 1

2d = 4

d = 2

Find a polynomial function p of lowest degree, having rational coefficients, with the given zero. 5i

weqwewe [10]

If we have one zero of +5i, we also have to have its conjugate which is -5i. Therefore, the factors that we will FOIL to get that polynomial are (x+5i)(x-5i). That distribution results in $x^{2} -25 i^{2}$ . I'm sure by now you know that i squared is equal to -1, so -25(-1) = 25. So our polynomial is $x^{2} +25=y$

State the domain of the rational function.

Makovka662 [10]

$f(x)=\dfrac{12}{13-x}$ is undefined where the denominator is zero. The domain is all values of x for which the function is defined.

The domain of f(x) is all real numbers except 13.
