Answer:

Difference = 2.25°

Step-by-step explanation:

Here we are given that at depth the Temperature T is inversely proportional to the depth x.

$T$ ∝ $\frac{1}{x}$

$T= 4500 \times \frac{1}{x}$

Where 4500 is constant

Now we have to find the difference in the temperature at 1200 mts and 3750 mts

1. x=1200

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{1200}$

$T= 3.75$

2. x=3750

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{3750}$

$T=1.2$

Hence Difference is

T = 3.75 -1.20

= 2.25

Therefore The difference of the temperature at 1200 mts and 3750 mts is T=2.25°

A rectangle is (x+10)ft by (x+4)ft. If a square of length xft on a side is cut from the rectangle, represent the remaining area

Andrei [34K]

Answer: $A(x)=14x+40$

Step-by-step explanation:

Given : The dimension of a rectangle is (x+10)ft. by (x+4)ft.

Then, Area of rectangle will be :-

$A_1(x)=(x+10)\times(x+4)=x^2+(10+4)x+40\\\\\Rightarrow\ A_1(x)=x^2+14x+40$

If a square of length xft on a side is cut from the rectangle, then the area of the square :-

$A_2(x)=x^2$

Now, the remaining area in the form of a polynomial function A(x) will be :-

$A(x)=A_1(x)-A_2(x)\\\\=x^2+14x+40-x^2=14x+40$

Hence, the remaining area in the form of a polynomial function A(x) will be :-

$A(x)=14x+40$
