16. The Pythagorean Theorem states that a ^ 2 + b ^ 2 = c ^ 2 if a and b represent the lengths of the legs of a right triangle a

nd c represents the length of the hypotenuse. aFind the length of the hypotenuse if the lengths of the legs are 9 cm and 12 cm. b. Find the length of each leg of an isosceles right triangle whose hypotenuse is 10 cm Round the nearest tenth of a centimeter

Step-by-step explanation:

a. Pythagoras formula stated above

so 9²+12²

81+144 is 225

√252 is 15cm

b. in this question well have to use surds

an isosceles triangle had a 90 and 2x45 degree angles

we hypotenuse is 10cm

√a²+a² =10cm

√2a² is 10cm which makes

a√2 equals 10

then rearrange

a=10/√2= 5√2

the answer is 5√2

Find the domain for the particular solution to the differential equation dy dx equals the quotient of 3 times y and x , with ini
Svetach [21]
For this case we have the following difference equation:
 dy / dx = 3xy

 Applying separable variables we have:
 dy / y = 3xdx

 Integrating both sides we have:
 \int\ ({1/y}) \, dy =  \int\ {3x} \, dx
 ln (y) = (3/2) x ^ 2 + C

 applying exponential to both sides:
 exp (ln (y)) = exp ((3/2) x ^ 2 + C)

 y = C * exp ((3/2) x ^ 2)
 For y (1) = 1 we have:
 C = 1 / (exp ((3/2) * 1 ^ 2))

C = 0.2
 Thus, the particular solution is:
 y = 0.2 * exp ((3/2) x ^ 2)

 Whose domain is all real.
 Answer:
 y = 0.2 * exp ((3/2) x ^ 2)
 Domain: all real numbers

Hatshy [7]

Answer:

8:07 am

Step-by-step explanation:

It takes 9 minutes to walk from his house to the bus station.  It then takes 92 minutes for the bus to travel from Birmingham to Coventry.  After arriving, he takes 12 minutes to reach his workplace.  This takes a total of 113 minutes.

9 + 92 + 12 = 113

Convert 113 minutes to hours and minutes.

113 - 60 = 53

1 hr and 53 min

He has to be at work by 10.  Subtract the time it takes to get to his work by the time he has to get there.

10 - 1 hr = 9

9 - 53 min = 8:07

The latest time he can leave is 8:07.
