Answer:

21 cm.

Step-by-step explanation:

V = π r^2 h

1029π = π * 7^2 * h   The π is common so:

1029 = 7^2 h

h = 1029 / 49

= 21 cm.

Answer:

Height is 21cm

Step-by-step explanation:

Volume of the cylinder = 1029pi

Base area = 7x7xpi = 49pi

Therefor the height = 1029pi/49pi=1029/49 = 21cm

The correct answer is {1, 2, 5, 6}.

A intersect B would be {3, 4}; the complement of this is everything else.

The table below shows selected points from a function.
FrozenT [24]

Answer:

<em>True </em>

Step-by-step explanation:

<em>Rate Of Change Of Functions </em>

Given a function y=f(x), the rate of change of f can be computed as the slope of the tangent line in a specific point (by using derivatives), or an approximation by computing the slope of a secant line between two points (a,b) (c,d) that belong to the function. The slope can be calculated with the formula

\displaystyle m=\frac{d-b}{c-a}

If this value is calculated with any pair of points and it always results in the same, then the function is linear. If they are different, the function is non-linear.

Let's take the first two points from the table (1,1)(2,4)

\displaystyle m=\frac{4-1}{2-1}=3

Now, we use the second and the third point (2,4) (3,9)

\displaystyle m=\frac{9-4}{3-2}=5

This difference in values of the slope is enough to state the function is non-linear

Answer: True

Three fourths of a number p less than two is five sixths of another number r plus five solve for r
maw [93]
r = -3/4p - 18/5 
(or you could put 3.6 or 3 3/5 instead of 18/5)

2 - 3/4p = 5/6r + 5 
-5                     -5
-3 - 3/4p = 5/6r
 /(5/6)       /(5/6) 
-18/5 - 3/4p = r 
-3/4p - 18/5 = r
