The packaging lists a model airplane’s length as 10.5 in. It also gives the scale as 1:83. What is the length of the actual airp

Kruka [31]

Since the scale is 1:83, the real airplane is 83 times longer than the model airplane.

real length = 10.5 in * 83 = 871.5 in

Now we convert 871.5 in into ft.
1 ft = 12 in, so 1 in = 1/12 ft
We divide the number of inches by 12 to find the number of feet.

871.5 in = 871.5/12 ft = 72.625 ft

Wayne's gym locker is a rectangular prism with a width and height of 12

Gnom [1K]

Answer:

Volume = (2890 and 5/8) inches^3

Step-by-step explanation:

Height = 12 and 1/2inches = 25/2

Width = 12 and 1/2inches = 25/2

Length = 6 inches > width = 6 + width

= 6 + (12 and 1/2) = 18 and 1/2

Length = 18 and 1/2 inches = 37/2

Volume of prism = length × breadth × height

Volume of rectangular prism = (25/2)×(25/2)×(37/2)

Volume of rectangular prism = (23125/8) inches^3

Volume of rectangular prism = (2890 and 5/8) inches^3

Which of the following is a polynomial with roots negative square root of 5, square root of 5, and 3?

Alex Ar [27]

Answer:

$x^{3}-3x^{2}-5x+15$

Step-by-step explanation:

The roots of the given polynomial are: $-\sqrt{5}, \sqrt{5}, 3$

Since, $-\sqrt{5}, \sqrt{5}, 3$ are the roots of the polynomial, according to the factor theorem, $(x - (-\sqrt{5})), (x-\sqrt{5}), (x-3)$ would be the factors of the polynomial.

Since we have the factors of the polynomial, we can multiply them to get the desired polynomial.

Let the polynomial be represented by P(x), so

$P(x) = (x - (-\sqrt{5}))(x-\sqrt{5})(x-3)\\\\ P(x)=(x +\sqrt{5})(x-\sqrt{5})(x-3)\\\\ P(x)=(x^{2}-(\sqrt{5} )^{2})(x-3)\\\\ P(x)=(x^{2}-5)(x-3)\\\\ P(x)=x^{3}-3x^{2}-5x+15$
