What is h(-2) equal to? h(a) = a+10/4 h(-2) – [1]

Mathematics

For this case we have a function of the form:

y = h (a)

Where:

h (a) = \frac {a + 10} {4}

We must find the value of the function whena = -2. Substituting:

h (-2) = \frac {-2 + 10} {4}\\h (-2) = \frac {8} {4}\\h (-2) = 2

Thus, the value of the function is 2 when a = -2

Answer:

h (-2) = 2

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
