Answer:
(a) The unit of 70.5 is lbm/ft^3 and the unit of 8.27×10^-7 is in^2/lbf
(b) density = 0.1206g/cm^3
(c) rho = 0.1206exp(8.27×10^-7P)
Step-by-step explanation:
(a) The unit of 70.5 is the same as the unit of rho which is lbm/ft^3. The unit of 8.27×10^-7 is the inverse of the unit of P (lbf/in^2) because exp is found of a constant. Therefore, the unit of 8.27×10^-7 is in^2/lbf
(b) P = 9×10^6N/m^2
rho = 70.5exp(8.27×10^-7× 9×10^6) = 70.5exp7.443 = 70.5×1.71 = 120.6kg/m^3
rho = 120.6kg/m^3 × 1000g/1kg × 1m^3/10^6cm^3 = 0.1206g/cm^3
(c) Formula for rho (g/cm^3) as a function of P (N/m^2) is
rho = 0.1206exp(8.27×10^-7P) (the unit of 0.1206 is g/cm^3)

Answer:
The correct option is A) 3 square inches;
.
Step-by-step explanation:
It is given that the length of the frame is (2x-3) and the width is (x-2)
The area of the rectangle is: 
Where, A is the area l is the length and w is the width of the rectangle.
Put
and
in the area of the rectangle.

The area of the frame expressed as a polynomial is
.
Now substitute x=3 in
.

The area of the frame is 3 square inches.
Hence, the correct option is A) 3 square inches;
.

thousandths place: 456.2991
Answer:
make the denominators ( bottom number ) the same and whatever u do to that do to the top
Step-by-step explanation:
e.g ½ - ⅓
make the common denominator 6
to get from 2 to 6 u times by 3 so it wud be 3/6
and then to get from 3 to 6 u times by 2 so do the same to the numerator (top number) so u get 2/6
3/6 take away 2/6 is 1/6
