We need only focus on the standard equation of a circle centered at the origin with radius r: x^2 + y^2 = r^2. Here, r = 10 and so r^2 = 100.

Thus, in this case, the equation of the circle is x^2 + y^2 = 10^2.

A woodworking artist makes two types of carvings: type X and type Y. He
ivolga24 [154]

Answer:

part C. 3x + 2y <u>< </u>30, 5x + 7y <u><</u> 105

Step-by-step explanation:

Part 1:

spends 3 hours making each type X (3x)-each type x will take 3 hours so as the number of type x increases, the hours will increase by 3.

spends 2 hours making each type Y (2y)-each type y will take 2 hours so as the number of type y increases, the hours will increase by 2.

Part 2:

he can spend up to 30 hours each week making carvings. (<u><</u>30)-because he cannot spend more than 30 hours

Therefore, He has to spend 30 hours or less to make type X and type Y.

3x + 2y <u>< </u>30

Part 3:

His  materials cost him $5 for each type X carving. (5x)-each type x will take $5 so as the number of type x increases, the cost will increase by 5.

His materials cost him $7 for each type Y carving, (7y)-each type y will take $7 so as the number of type y increases, the cost will increase by 7.

Part 4:

he must keep his weekly cost for materials to $105 or less (<u><</u>105)-total cost cannot be more than $105.

Therefore, the total cost of making x and y should be $105 or less.

5x + 7y <u><</u> 105

Hope this helps you

Step-by-step explanation:

43. A "Square" cornfield, which means all 4 sides has the same lenght BxH

164.000 ft^2=404.96 NO

156.816 ft^2=396 Yes

174724 ft^2=418 Yes

215908  ft^2=464.66 NO

44. it's the same here, if the area is 81. then each side of the square is 9

1st figure: it has 12 sides x9 =108

2nd figure: it has 10 sides x9=90

3rd figure: has also 12 sides x9=108

45. 13^3= 13x13x13 = 2197

46. 25^2= 25x25 = 625

47.  15^3= 15x15x15 = 3375

48. 34^2= 34x34 = 1156

49.  5 root121= 5 (11)=55

50. -6.root36= - 6 (6)= -36

51.  10 root3 (8) = 10(2) = 20

52. -4. root 144= -4(12) = -48
