Vladimir79 [104]

Answer: A commercial bank.

if i could get brainliest that would be great

Step-by-step explanation:

Commercial banks are financial institutions whose functions, among many, are: offering banking services to individuals, groups and companies, to make profit. One of the roles performed by these types of financial institutions is to credit loans to individuals, small businesses, and other groups, and as such, they are the first line to which a small business, such as the one controlled by Glenn and Maggie, would go to, to request a loan to be able to open up their other branches. This bank would give them the loan and allow them to make profit, without having any ties to the banking institution, just as long as they return the investment given to them.

The gross domestic product​ (in billions of​ dollars) can be approximated by ​p(t)equals564 plus t left parenthesis 36 t supersc
nirvana33 [79]

We have been given gross domestic product​ (in billions of​ dollars) can be approximated by P(t)=564+t(36t^{0.6}-101).

(a) In this part, we need to compute the derivative of this function:

P'(t)=\frac{d}{dt}(564+t(36t^{0.6}-103))\\P'(t)=\frac{d}{dt}(564)+\frac{d}{dt}(t(36t^{0.6}-103))\\P'(t)=0+57.6t^{0.6}-103\\

P'(t)=57.6t^{0.6}-103

(b) In this part, we need to find the value of P'(45). So, we will substitute t=45

P'(45)=57.6(45)^{0.6}-103\\P'(45)=565.3924-103\\P'(45)=462.39 Billion dollars per year.

(c) P'(45)=462.39 represents that 45 years after 1960, that is, in 2005, the GCP was changing at a rate of 462.39 billion dollars per year.

What is the value of x in the equation 4x + 8y =40, when y=0.8
Naily [24]

Answer:

x= 8.4

Step-by-step explanation:

y=0.8

4x + 8y =40

4x + ( 8 x 0.8) = 40

4x + (6.4)  =40

4x = 40 - 6.4

4x = 33.6

x = 8.4
