Supplementary angles are angles that add up to 180 degrees.

m<3 + m<4 = 180 degrees

116 + m<4 = 180 degrees.

Subtract 116 from both sides.

m<4 = 64 degrees

Zigmanuir [339]

Answer:

Linear function

Explanation:

Given the scattered plot in the attached image.

We want to identify the type of function that can best model the given scattered plot.

The scattered point as shown in the attached image form a straight line, So, the best type of function that can best model it is a linear function (straight-line graph).

Write a polynomial function f of least degree that has a leading coefficient of 1 and the given zeros. Write the function in sta

NeX [460]

Answer:

$f(x)=x^3+(3+\sqrt{5})x^2+(6\sqrt{5}-18)x$

$f(x)=x^3+3x^2+\sqrt{5}x^2-18x+6\sqrt{5}x$

Step-by-step explanation:

A polynomial function with 3 zeroes is going to be of degree 3, so we're going to have at least least 3 factors of the form $x-a$ , where a is a zero of the function. For three zeroes a, b, and c, we'd have the factors $x-a,\ x-b,$ and $x-c$ , making our function look like
