Let the polynomial function g be a function of x. The graph of the polynomial has four zeros at -5, -3/4,0,7. Select all the expressions that could represent g:
A. -4(x+5)(4x+3)(x-7)
B.-4(x+5)(4x+3)(x-7)^2
C. 4x(x-5)(x+3/4)(x+7)
D.4x(x+5)(3x-4)(x-7)
E. -x(x+5)(x+3/4)(x-7)

Can you help me out?

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
