Question #1 Matalea created a rectangle where the length was eight more than the width. She then determined that the area of a rectangle could be found by using the function A(x) = x +8x, where x is the width of the rectangle. If the area of the rectangle is 33 in., what is the width of the rectangle?

A rectangular parcel of land has width, w feet. The length of the diagonal, d, between opposite corners is 18 feet more than the length of the parcel. Note that d is lowercase. (a) Express the length, L, of the parcel as a function of d. (b) Express the width, w, of the parcel as a function of d. (c) Express the area, A, of the parcel as a function of d. L = W = A = (d) Suppose a fence is to be built around the perimeter of the rectangular parcel of land. The fencing material will cost $25 per foot. Express the total cost, C, of fencing the parcel as a function of d. C =

Find the x-intercept and y-intercept of the following function y = -7x 16

A rectangular dock that measures 12 feet by 16 feet is treated with auniform strip of nonslip coating along both sides and both ends. How wide isthe strip if one-half of the dock is treated? If we let x represent the width of thestrip, then we can use the equation (16 -2x)(12 - 2x) = 1/2(12)(16) to determinethat the width of the strip is 2 feet. I've been doing well with polynomials I just do not understand visually what "treated along both ends and sides" mean. What is the end of a rectangle? Also, I do not understand the 2 in '2x' (2 times the width of the strip) why is that added? I guess I am more concerned about how the equation actually maps to the real world scenario.

Find the x-intercept and y-intercept of the following function y = 9x + 1 Answer: X = y =

The volume, V, of a sphere in terms of its radius, r, is given by V (r) = 7³. Express r as a function of V, and find the radius of a sphere with volume of 200 cubic feet. Round your answer for the radius to two decimal places. Enclose numerators and denominators in parentheses. For example, (a - b)/(1+n). Include a multiplication sign between symbols. For example, a * . r (V) = 640
