Answer:
Step-by-step explanation:
Given is a differential equation as

Divide this by t to get in linear form

This is of the form
y' +p(t) y = Q(t)
where p(t) = 1/t
So solution would be

siubstitute y(1) = 16

It will be 4 16 because it a circle on square timing 94 Fahrenheit
Answer:
<h2>18mins</h2>
Step-by-step explanation:
This problem is on combined work rate
given that
Marta can vacuum the house in 30 min
then her rate= 1/30
Also, her daughter will take 45 min to vacuum the house
her daughter's rate will be = 1/45
then the combined work rate is
1/30+1/45=1/T
30+45/30*45=1/T
75/1350= 1/T
1/18=1/T
This means that they will both take 18 minutes working together to vacum a house
