Pls help. What would be the equations for these two problems?

deff fn [24]

Answer: 150,000 = (n - 150)(n + 50)

33,600 = (2w - 40) (w)

<u>Step-by-step explanation:</u>

Let n represent the "number".

then width = n + 50

and length = (n + 50) - 200 --> n - 150

Area = Length x width

150,000 = (n - 150)(n + 50)

************************************************************

Let w represent the width

then width = w

and length = 2w - 40

Area = length x width

33,600 = (2w - 40)(w)

Which function is increasing?? :)

exis [7]

Answer:

$\large\boxed{B.\ f(x)=4^x}$

Step-by-step explanation:

Exponential function $f(x)=(a)^x$ is

increasing if $a > 1\to a\in(1,\ \infty)$

decreasing if $0 < a < 1\to a\in(0,\ 1)$

$A.\ f(x)=\left(\dfrac{1}{4}\right)^x\to a=\dfrac{1}{4}\in(0,\ 1)\to\text{decreasing}\\\\B.\ f(x)=4^x\to a=4\in(1,\ \infty)\to\text{increasing}\\\\C.\ f(x)=(0.4)^x\to a=0.4\in(0,\ 1)\to\text{decreasing}\\\\D.\ f(x)=\left(\dfrac{1}{2}\right)^x\to a=\dfrac{1}{2}\in(0,\ 1)\to\text{decreasing}$
