Evaluate integral from upper c to left parenthesis x plus y right parenthesis ds where c is the straight-line segment x equals 4 t, y equals left parenthesis 12 minus 4 t right parenthesis, z equals 0 from left parenthesis 0 comma 12 comma 0 right parenthesis to left parenthesis 12 comma 0 comma 0 right parenthesis.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

40 x 50 = 2000
