Answer:
The correct option is c.
Step-by-step explanation:
Given that,
u = 7i+4j and v = 2i-3j
We need to find the product of u and v. The dot product of two vectors is given by :

So, the dot product of u and v is equal to 2.
Hello.
The solutions found to radical equations are not necessarily viable. They sometimes result in inequalities, and have to be checked.

Answer:
Therefore
, A=184
Step-by-step explanation:
Given function is

where T(t) is the temperature in °C and t is time in minute and A and k are constants.
She noticed that after 18 minutes the temperature of the pie is 138°C
Putting T(t) =138°C and t= 18 minutes


.....(1)
Again after 36 minutes it is 184°C
Putting T(t) =184°C and t= 36 minutes


.......(2)
Dividing (2) by (1)


Taking ln both sides




Putting the value k in equation (1)





⇒A= 184.
Therefore
, A=184

Answer:
The first Graph
Step-by-step explanation:
-2a-5>3
Add 5 to both sides
-2a>8
Divide both sides by 2
a<4
