Answer:
Perimeter of the windows is P = 4s, or (here) P = 4(x+9) ft.
Step-by-step explanation:
If the area of the square is x^2 + 18x + 81 (ft^2), then the length of one side is given by the square root of that, and is x + 9 (ft). Note that (x + 9)^2 = x^2 + 18x + 81.
The perimeter of a square window of side length s is P = 4s.
Here, the perimeter of the square is P = 4(x+9) (ft).
Answer:
From the picture when the input of f(x) is 6 the output is 8
So it's just the reverse f^-1(8) when the input is 8 the output is 6
So f^-1(8) = 6
Hope this helps you
Answer:
<u>In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. </u>
<u>The abbreviation is sin. sin θ = opposite / hypotenuse.</u><u>2 cosA sinB = sin(A + B) − sin(A − B) 2 cosA cosB = cos(A + B) + cos(A − B) 2 sinA sinB = cos(A − B) − cos(A + B)</u>

Answer:
891 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of cross- section and h is the height (
The cross- section is a trapezium with area (A) calculated as
A = 
h ( a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 9, a = AB = 14 and b = CD = 8 , thus
A = × 9 × (14 + 8) = 4.5 × 22 = 99 cm² , thus
V = 99 × 9 = 891 cm³
Answer:
A) Vol_10_cubes = 2*(5^4) inch^3
B) Area_10_cubes = (2^2)*3*(5^3) inch^2
Step-by-step explanation:
A)The volume of a cube, as all sides are equal:
Vol_cube = (side)^3
side = 5 inches
Vol_cube = 5^3 inch^3
Since we have 10 cubes
10 = 2*5
Vol_10_cubes = 2*(5^4) inch^3
B) A cube has six faces, each with area equal to its squared side
Area_cube = 6*(side)^2
Area_cube = 6*(5)^2 inch^2
Area_10_cubes = 2*5*6*(5)^2 inch^2
Area_10_cubes = (2^2)*3*(5)^3 inch^2
