Answer:

<em>  The answer is \sin^{-1}x = y</em>

Step-by-step explanation:

    We need to find the inverse of the function

     y = sinx

    Taking \sin^{-1} on both sides

    \sin^{-1}y =  \sin^{-1}sinx

     \sin^{-1}y = x

     Substituting x to y and y to x

<em>      \sin^{-1}x = y</em>

     This is the required inverse of the function

     The graph of the function and its inverse is symmetric about y = x

<em>     The answer is \sin^{-1}x = y</em>

A company makes two different-sized ice cream cones. The smaller cones are 3.5 inches tall and have a diameter of 3 inches. The
barxatty [35]

Answer:

The Volume of large cone is  19.545 inches^3 greater than the smaller cone

Step-by-step explanation:

Given:

Size of the small cone =  3.5 inches

Diameter of the small cone  = 3 inches

Size of the large cone =  3.5 inches

Diameter of the small cone  = 3 inches

To Find:

How much greater, to the nearest tenth of a cubic inch, is the volume of the larger cone than the volume of the smaller cone = ?

Solution:

Volume of the small cone :

Radius = \frac{diameter}{2}

Radius = \frac{3}{2}

Radius = 1.5 inches

volume of the cone  =\pi rl

substituting the values,

=>\pi (1.5)(3.5)

=>\pi(5.25)

=> 16.485 inches^3

Volume of the large cone :

Volume of the large cone :

Radius = \frac{diameter}{2}

Radius = \frac{4.5}{2}

Radius = 2.25 inches

volume of the cone  =\pi rl

substituting the values,

=>\pi (2.25)(5.1)

=>\pi(11.475)

=>36.06 inches^3

Now ,

volume of small cone - volume of large cone

=>36.06 - 16.485

=>19.545 inches^3

Help me with 22 and 23
cricket20 [7]

22.

pythagorean theorem says legs a and b and hypotenuse c of a right triangle are related via the equation c²=a²+b². in other words, adding the sum of the squares of the legs get you the square of the hypotenuse

if the hypotenuse is 4 meters long, c = 4.

if one leg is 3 meters long, we can choose either a or b to be 3. it does not really matter. let us choose a = 3. now we have to find b.

if we have c²=a²+b², we can solve for b.

subtract a² both sides to get c²-a²=b², and then square root both sides to get

b = √(c²-a²)

plugging in our info we get

b = √(4²-3²) = √(16 -9) = √7

so the answer is √7 meters for 22


23

two triangles are similar, then the proportion of their sides are the same. the propotion between the smaller triangles' hypotenuse and 2cm leg is 5cm/3cm.

notice how the bigger triangle just have a doubled hypotenuse. therefore, the bigger triangle's x and y are just the corresponding smaller triangle values doubled.

x = 6 and y = 8
