PLEASE HELP A local boutique sells water bottles for a set price, plus an additional fee for each letter that customers would like engraved on their water bottle. The pricing for up to 4 engraved letters is shown in the table below. Write an equation in slope-intercept form to represent the relationship between the number of letters and the total cost.
#of letters = 0, 1, 2, 3, 4
Total cost= 18.99,1 9.34, 19.69, 20.04, 20.39

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x

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 > ?

Select the correct answer. which exponential function has an x-intercept? oa. (x) - 100x-5-1 ob. (x) = 3x4+2 oc. kx) = 7x-1 + 1 od. 1(x) =-3x+1 - 3
