Answer:

cbrt(x+1)-3=y

Step-by-step explanation:

The inverse of a function is when the domain and range are swapped. So to find the inverse simply swap the x and y in the equation and then solve for y.

$y = (x+3)^3-1\\x=(y+3)^3-1\\x+1=(y+3)^3\\\sqrt[3]{x+1}=y+3\\\sqrt[3]{x+1}-3=y$

Find the area of a sector with a central angle of 140° and a diameter of 9.6 cm. Round to the nearest tenth.

olchik [2.2K]

Answer:

$A=28.1\ cm^2$

Step-by-step explanation:

The area of a circular sector with a central angle θ and radius r is given by:

$\displaystyle A=\frac{1}{2}r^2 \theta$

Note: The angle must be in radians.

We need to find both the radius and the angle in radians.

Diameter = 9.6 cm

Radius r=Diameter/2=4.8 cm

Angle in radians= Angle in degrees*π / 180

θ = 140*π / 180 = 2.4435 rad

Now we calculate the area:

$\displaystyle A=\frac{1}{2}(4.8)^2 2.4435$

$\boxed{A=28.1\ cm^2}$

Georgia adds two proper fractions and gets 8/7 as an answer Work out the two fractions.

LenaWriter [7]

Answer:

1/2 and 9/14

Step-by-step explanation:

Let the first fraction be 1/2

Let the second fraction be x

1/2 + x= 8/7

x= 8/7-1/3

= 16-7/14

= 9/14

Hence the two numbers are 1/2 and 9/14
