Answer:

Step-by-step explanation:

VOLUME...

1) π*r^2*h

π*(2.5)^2 *h

(π)*(2.5)^2* 6

= 117.8

2) π*r^2*h + 1/2 *[(4/3) · π · r3]

(π)*(3)^2* 3 + 1/2 *[(4/3) · π · 3^3]

        84.8+ 56.5 = 141.41

3) (1/3) π*r^2*h

(1/3) π*3^2*h

3^2 + h^2 = 36

h = sqrt(27) = 5.1

(1/3) π*3^2*5.1

= 48.06

For each function shown:
yaroslaw [1]

Answer:

Step-by-step explanation:

Function (1) has been given as,

y = 0.5 + 3x

Table for the points on this function,

x        0         1          2          3         4

y       0.5     3.5       6.5      9.5     12.5

y_2-y_1=3.5-0.5=3

y_3-y_2=6.5-3.5=3

There is a common difference of 3 each successive term of y from the previous term.

Therefore, starting point of the function is (0, 0.5)

There is a linear growth of 3 with the increase in the value of x.

Function (2),

y = 3(0.5)ˣ

x       0         1          2           3           4

y       3        1.5     0.75     0.375   0.1875

Starting point of the function will be (0, 3)

There is a common ratio of 0.5 in each successive term to the previous term.

\frac{y_2}{y_1}=\frac{1.5}{3}=0.5

\frac{y_3}{y_2}=\frac{0.75}{1.5}=0.5

Function (2) increases exponentially with a common ratio of (0.5) with the increase in x.

How can you determine whether a number is a solution of an equation ?
raketka [301]
Solution or an equation? A solution should have the equal sign next to it. And an equation should have with an unknown solution till you solved it. For ex:

5,534,234              9+9 
Solution                    equation

Also solutions won't have an equation. Like that.
