The value of a rectangle is 128 cubic yards. The base of the prism has an area of 8 square yards.

san4es73 [151]

Answer:

<h2>16 yards</h2>

Step-by-step explanation:

Given,

Volume of the rectangular prism = 128 cubic yards

Base area of the prism = 8 square yards

Let,

Height of the prism be = h

As we know, 

Base area × height = Volume of the given prism

Therefore, 

By the problem,

=> 8 sq. yd × h = 128 cu. yd

=> 8h = 128

(On dividing 8 from both sides)

$= > \frac{8h}{8} = \frac{128}{8}$

(On Simplification)

=> h = 16

Hence, the height (h) of the prism is 16 yards (Ans)

Explain why the function is discontinuous at the given number

Blizzard [7]

For $f$ to be continuous at $x=5$ , we need to have

$\displaystyle\lim_{x\to5}f(x)=f(5)$

Note that $x\to5$ means that $x\neq5$ , but that $x$ is *approaching* 5. We're told that for $x\neq5$ , we have

$f(x)=\dfrac{x^2-5x}{x^2-25}$

We can write

$\dfrac{x^2-5x}{x^2-25}=\dfrac{x(x-5)}{(x+5)(x-5)}=\dfrac x{x+5}$

and the limit would be

$\displaystyle\lim_{x\to5}\frac x{x+5}=\dfrac5{5+5}=\dfrac5{10}=\dfrac12\neq1=f(5)$

and so $f$ is discontinuous.

Answer:

1,172.3 cm³

Step-by-step explanation:

Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is

V = (πd²/4)h

d = 4 cm

h = 20 cm

Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.

Add

20 + 4 = 24

Then

28,134.4 ÷ 24 = 1172.26

Rounded to the nearest 0.1 or the Tenths Place = 1,172.3

Therefore, 1,172.3 rods will be made per hour.
