The ODE appears to be
It's separable; we can write
and integrating both sides yields
Answer:
The cold length of metal rod is 435.14 cm
Step-by-step explanation:
Given as :
The percentage expansion of metal rod = 3.5%
The quantity of expansion = 15.23 cm
Let the cold length be x
So, 3. 5% of x = 15.23 cm
Or, 0.035 × x = 15.23 cm
Or, x = cm
∴ x = 435.14 cm
Hence The cold length of metal rod is 435.14 cm Answer
Any two lines that cross form 2 sets of equal acute angles and 2 sets of obtuse angles. One of each will add to 180o.
obtuse + acute = 180
obtuse = 145
145 + acute = 180 subtract 145 from both sides.
acute = 180 - 145
acute = 35
