Answer:
Perimeter = 60ft = 2(4x + x)
breadth = 6ft
length = 24ft
Step-by-step explanation:
Perimeter = 2 (L + B)
L =length
B = Breadth
x= breadth
4x = length
Perimeter = 60ft = 2(4x + x)
Dividing both sides by 2 :
30ft= 4x + x
30ft = 5x
divide both sides by 5
6ft= x
breadth = 6ft
length = 4x= 4 x 6 = 24ft
Answer:
y=x^2-4x-3
Step-by-step explanation:
y= (x-2x -1)(х+3)
= x^2+3x-2x^2-6x-x-3
= -x^2-4x-3
Answer:
-10 -12 -14 -16 -18 -20 -22 -24 -26 -28
Given:
.
Exponential regression model is
![y_1\sim a(b)^{x_1}](https://tex.z-dn.net/?f=y_1%5Csim%20a%28b%29%5E%7Bx_1%7D)
To find:
The exponential regression representing the population of Lazy Town as a function of time in years.
Solution:
Exponential regression model is
...(i)
We have,
.
Substituting
and
in (i), we get.
![y_1\sim 8000(0.9)^{x_1}](https://tex.z-dn.net/?f=y_1%5Csim%208000%280.9%29%5E%7Bx_1%7D)
Therefore, the exponential regression representing the population of Lazy Town as a function of time in years, is
.
