4.	the temperature recorded at 12 noon was 15 degrees above zero if it decreases at rate of 3 degree Celsius per hour until midnight at what time will the temperature be 9 degree Celsius before 0 and what would be the temperature at midnight
Answer» Answer:8 pm. Step-by-step EXPLANATION:As it decreases by a constant rate we can easily find the TIME in which the temperature was -9°Celsius. Difference between starting and ending temperature=15-(-9)=15+9=24°Celsius So the temperature decreases by 24 degrees . As it REDUCES by 3 degrees each HOUR, the number of HOURS =24/3=8 hours Therefore the time at which it was -9°Celsius= 8 hours after 12 noon =8 pm.

Find the value of k for which the following quadratic equation has two equal roots2x^+kx+3=0

Answer»

Step-by-step explanation:

given equation is :-

2x+kx+3=0

a=2

b=k

c=3

D=b^2-4ac

D= (k) ^2 -4(2)(3)

D = k^2-24

For equal roots, DISCRIMINANT

k^2-24=0

k^2=24

k =+√24

k = +2√6

A number consists of two digits, the difference of whose digits is 3. If 4 times the number is equal to 7 times the number obtained by reversing the digits, find the number.

Answer»

Step-by-step explanation:

let the NUMBER be 10x+y

given x-y=3

A.T.Q

4(10x+y)=7(10y+x)

40x+4y=70y+7x

33x=66y

33x-66y=0

x-2y=0

from (i) y=x-3

putting the VALUE we get

x-2(x-3)=0

x-2x+6=0

-x=-6

(x=6)

substituting the values,

x-y=3

6-y=3

(y=3)

HENCE the number is 10x+y i.e.,

10(6)+3=63 ans.
