what is the value of the y-coordinate of the y-intercept of the function shown below? f(x)=-4x^2+2x-5

-5

Step-by-step explanation

Given the function  f(x)=-4x^2+2x-5, the y intercept occurs at x = 0

Substitute x = 0 into the function and find y as shown;

f(x)=-4x^2+2x-5

f(0)=-(0)^2+2(0)-5

f(0)=0-5

f(0) = -5

The coordinate point is (0, -5)

Hence the value of the y coordinated is -5

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
