Answer 4

hi

Answer 5

5. given a right triangle with length of hypothenuse = 10
using pythagora you know that 10^2 = x^2 +y^2

and you know that area of a triangle equal base time height divide 2 so in this case area = x time y divide 2

100 = x^2 +y^2
A = x*y/2

from these you need calcule the values of x and y for what the area will be maximum

hope helped

Answer 6

okay so square root 50

Answer 7

that's the answer my teacher gave me

Answer 8

for both x and y

Answer 9

@Hero

Answer 10

question 7?

Answer 11

but do you understand why sqrt50 ?

Answer 12

yes about 7.1 is 50 +50=100

Answer 13

7.1^2

Answer 14

bc. 100 = x^2 +y^2

100 = (sqrt50)^2 +(sqrt50)^2

100 = 50 +50

Answer 15

yes

Answer 16

yes and you need to know again that area will be maxim than x=y

ok.?

Answer 17

I know don't feel like typing everything I have but I got the answer

Answer 18

for 7. you need to know the formula of perimeter of a cyrcle

Answer 19

2pir

Answer 20

yes so given that the perimeter increasing 3 m/s what result from this ?

Answer 21

us what you know

2pir increasing 3 m/s

from this result that r increasing 3/(2pi) m/s

do you understand it ?
