Neveah has created the function of f(x) = 2x+4/3 to represent the growth of her hair, where x represents the number of months si
Andre45 [30]
F(x)=2x+4/3

Replace f(x) by y:
y=2x+4/3

Solving for x:
y-4/3=2x+4/3-4/3

Subtracting the two terms on the left side of the equation:
(3y-4)/3=2x

Dividing both sides of the equation by 2:
[(3y-4)/3]/2=2x/2
[(3y-4)/3]*(1/2)=x
[(3y-4)*1]/[(3)*(2)]=x
(3y-4)/6=x
x=(3y-4)/6

Replace "x" by "f^(-1) (x)" (inverse function) and "y" by "x":
f^(-1) (x) = (3x-4)/6   Inverse function

Then, for x=6 
f^(-1) (6) = [ 3(6)-4]/6
f^(-1) (6) = (18-4)/6
f^(-1) (6)= 14/6
f^(-1) (6) = 7/3

Her hair will have grown 6 after 7/3 = 2.33 months

Answer:

Step-by-step explanation:

Volume of the figure = Base area * height

Base area:

Base area = area of trpezium + area of triangle

<u />

<u>Trapezium:</u>

a, b area the length of parallel sides and h is the height of trapezium.

a = 8 m ; b =  5 m & h = 3 m

\boxed{ \text{ Area of trapezium = $\dfrac{(a +b)*h}{2} $}}

                               =\dfrac{(8+5)*3}{2}\\\\\\=\dfrac{13*3}{2}\\\\\\= \dfrac{39}{2}\\\\\\= 19.5 \ m^{2}

<u>Triangle:</u>

height = 4 m & base = 8 m

\boxed{\text{Area of triangle =$\dfrac{1}{2}*base*height$}}

                           =\dfrac{1}{2}*8*4\\\\\\= 4*4\\\\= 16 \ m^{2}

Base area = 19.5 + 16

                 = 35.5 m²

Volume of the figure = Base area * height

                                     = 35.5 * 14

                                      = 497 m³

A right prism has a volume of 65 cubic inches. The prism is enlarged so its height is increased by a factor of 20, but the other
Helga [31]

Answer:

Volume of a right prism = 65 cubic inches

Its height is increased by a factor of 20.

To find:

The new volume of the prism if the other dimensions do not change.

Solution:

The volume of a prism is:

Volume=Bh

Where, B is the base area and h is the height.

A right prism has a volume of 65 cubic inches.

65=Bh

The height of prism is increased by a factor of 20. So, the new volume is:

Volume=B(20h)

Volume=20(Bh)

Volume=20(65)

Volume=1300

The volume of the new prism is 1300 in³.

Therefore, the correct option is B.
