A = length x width
15,000 = (w + 30) x w
15,000 =
+ 30w
0 =
+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5
. Because distance cannot be negative, the width is -15 + 5
meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
Triangle area= b*h/2
Plug in the values:
25*8/2
200/2
100
Final answer: 100 ft^2
Answer:
I'm not sure but i thinks it's
Slope = -1/2
Y intercept = 7
We have been given gross domestic product (in billions of dollars) can be approximated by 
.
(a) In this part, we need to compute the derivative of this function:
(b) In this part, we need to find the value of P'(45). So, we will substitute t=45
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.
