(1 point) let f(x, y)=x2ex2 and let r be the triangle bounded by the lines x=2, x=y/3, and y=x in the xy-plane.(a) express ∫rfda as a double integral in two different ways by filling in the values for the integrals below. (for one of these it will be necessary to write the double integral as a sum of two integrals, as indicated; for the other, it can be written as a single integral.)∫rfda=∫ba∫dcf(x, y)dy dxwhere a= , b= , c= , and d= .and ∫rfda=∫ba∫dcf(x, y)d d +∫nm∫qpf(x, y)d dwhere a= , b= , c= , d= , m= , n= , p= , and q= .(b) evaluate one of your integrals to find the value of ∫rfda.∫rfda=

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
