Answer:
D.) 38.6 m
Step-by-step explanation:
Use the cosine ratio:

Because we are given the measure of an angle and the length next to it (adjacent), and we need to find the hypotenuse (the hypotenuse is NEVER considered the adjacent side). Insert the values:

Now isolate the variable. Multiply both sides by x:

The x's on the right side cancel each other out. Simplify:

Now divide both sides by cos75°:

The cos75° on the left side cancels each other. Simplify:

Insert this value into a calculator to simplify the value of x:

The hypotenuse is 38.6 m.

Since they are starting with 270, the y intercept is going to be 270, now since they are losing 15 food everyday, the slope is going to be -15 so the final equation is y=-15x+270

Answer:
roots
Step-by-step explanation:
A quadratic equation with real or complex coefficients has two solutions, called roots.
Roots are also called x-intercepts or zeros. ... The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
