Ab=10
a^2+b^2=30
((a+b)^2=a^2+2ab+b^2=a^2+b^2+2*10=30+20=50
Answer:
4.4 hours
Step-by-step explanation:
Let the number of hours = x
Ida needs to hire a singer for her wedding.
For Singer A
Singer A is offering his services for an initial $65 in addition to $13.15 per hour.
65 + 13.15x
Singer B
Singer B is offering her services for an initial $73 in addition to $11.35 per hour.
73 + 11.35x
We equate both singers together
Singer A = Singer B
65 + 13.15x = 73 + 11.35x
We collect like terms
13.15x - 11.35x = 73 - 65
1.8x = 8
x = 8/1.8
x = 4.4444444444 hours
Approximately = 4.4 hours
The two singers will charge the same amount of money after 4.4 hours
Answer:
As we can see the domain is the:"number of minutes water has been added". And from the information given the values for T are between 0 and 60 so then the set of values would be "the set of all real numbers from 0 to 60", and we start from 0 because the time can't be negative.
For the range who represent "amount of water in the pond (in liters)" we need to analyze the possible values for W, since T is defined between 0 and 60 the limits for W are:


So then the set of values for the range are "the set of all real numbers from 300 to 2400" liters.
Step-by-step explanation:
Assuming this complete problem: "The owners of a recreation area are filling a small pond with water. Let W be the total amount of water in the pond (in liters). Let T be the total number of minutes that water has been added. Suppose that
gives as a W function of during the next 60 minutes.
Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.
"
