with a scale factor

length becomes scale factor * length

area becomes scale factor^2 * area

volume becomes scale factor ^3 * volume

if the diameter is doubled  the scale factor is 2

Volume becomes 2^3 * volume

the volume increases by a factor of 8

22+6[(14-5)÷3(17-14)]
mina [271]

The simplification of the expression is 28. The mistake in your calculation occurred in step 3.

<h3>What is the process involved in simplifying expression involving brackets?</h3>

TO simplify expressions involving brackets, we use a common method called BODMAS (Brackets, Of, Division, Multiplication, Addition, and Subtraction).

This means that we will first solve the expression in brackets first, followed by division, multiplication, addition, and subtraction as the case may be.

Now, from the given information, we have:
= 22+6[(14-5)÷3(17-14)]

solving parameters in the bracket first, we have:
= 22 + 6[(9) ÷3(3)]

= 22 + 6[(9) ÷9]          

  • The above step is where you missed it from your calculation, you must first open all brackets within brackets before solving them.

= 22 + 6[(9) ÷9]    

= 22 + 6[ 1]

= 22 + 6

= 28

Describe the discontinutiy for the function f(x)= x^2+5/x-5
coldgirl [10]

Answer:

f(x) = x² + 5 / x - 5

There is infinite discontinuity at x = 5. At this value, the graph becomes undefined because the denominator is 0.

vampirchik [111]

Answer:

D) 1000

Step-by-step explanation:

<u><em>The options of the question are</em></u>

A) -1000 B) -7 C) 7 D) 1000

we know that

The sea level is the reference value to represent elevation, and it is considered as zero level.

Above sea level is considered positive and below the sea level is considered negative

we have

New Orleans is 7 feet below sea level

so

New Orleans elevation is -7 ft

Oklahoma is 1000 feet above the sea level

so

Oklahoma elevation is +1000 ft

therefore

Oklahoma City's elevation is represented by 1000
