Find the set of points in the plane where each function is discontinuous. Be sure you can explicitly write out what these points are! Then choose the shape of the set of points where the function is discontinuous. a. f(x, y) 60 + 3y 9x - 4y The set of points at which f(x, y) is discontinuous is ?
b. f(x, y) бу 22 + 3 The set of points at which f(x, y) is discontinuous is ?
c. g(x, y) = 6x2 + 3y2 22 17:+ 72 The set of points at which g(x, y) is discontinuous is ?
d. g(x, y) 6 3x +9y2 The set of points at which g(x, y) is discontinuous is ?

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
