Simply each equation is manipulated by the x in the way that the function is telling you to

x = a
f (a) = 8 + 2(a)^2

x = a + h
f (a + h) = 8 + 2( a + h) ^ 2

the last case is represented by two scenarios
x = a + h ... x = a/h

f (a + h) - f( a / h) =
(8 + 2(a + h) ^2) - (8 + 2(a / h)^2)

(Please Help Will mark brainliest) What is the total surface area of the triangular prism?
PolarNik [594]

Answer:

63m^2

Step-by-step explanation:

Find the area of each base

2.5(10)= 25

1.5(10) = 15

2(10) = 20

Add them together

20 + 15 + 25 = 60

Now find the area of the triangles at each side

2(1.5)(1/2) = 1.5

Since there are two triangles, multiply the area by 2

1.5(2) = 3

Add the areas together

60 + 3 = 63

There's your answer

A solid right circular cone of diameter 14cm and height 8cm is melted to form a hollow sphere. If the external diameter of the s
pshichka [43]

Answer:

Step-by-step explanation:

Diameter of cone=14 cm

so, Radius of cone= 7cm

     Height of cone= 8cm

     ∴ Volume of cone= 1/3*pi*r^2*h

                                 =1/3*pi*49*8 cm^3

In Sphere, External Radius R=5cm

         Let, Internal Radius = r  

   Volume of Sphere = External Volume- Internal Volume

                                 = 4/3*pi*R^3-4/3*pi*r^3

                                 =4/3*pi[R^3-r^3]

                                 =4/3*pi[5^3-r^3]

But During Conversion Volume Remains Same

    So, Volume of Sphere=Volume of Cone

           4/3*pi[125-r^3]= 1/3*pi*49*8

           4[125-r^3]=49*8

             [125-r^3]=49*2

              r^3=125-98

              r^3=27

              so, r =3 cm

          Internal Radius= 3cm

   So, Internal Diameter=3*2= 6cm
