Numerals are symbols and figures that are used to denote or represent numbers.

It is false that “for a set of whole numbers, the longest numeral will belong to the largest number”

<h3>How to determine the true statement</h3>

The length of a numeral does not determine the value of the number,

The above statement means that

The whole number with the longest numeral in a set may or may not be the largest.

Take for instance the numbers 8 and 9.

In Roman numerals,

8 is represented with VIII and 9 is represented with IX

The numeral VIII is longer than the numeral IX, but IX is greater than VIII

Hence, the statement is false

The area of a circle, in terms of π, is 196π m2.<br> Find the value of the radius.

AleksandrR [38]

Step-by-step explanation:

if area of circle = pi times radius^2,

area of circle divided by pi = radius^2

so, square root (area of circle divided by 2) = radius.

so, 196pi = m2

approx 616

616=m2

sqrt 616 =m

approx value of radius is 25 or 24.8

How long will it take to earn $1800 in interest if $6000 is invested at a 6% annual interest rate? how many years

Simora [160]

Answer:

Total interest will $1800 after 5 years.

Step-by-step explanation:

It is given that the principle amount is $6000.

Rate of interest rate is 6% per annum.

Total interest is $1800.

Formula for simple interest is

$I=\frac{P\times r\times t}{100}$

Where, P is principle, r is rate of interest in percent and t is time in years.

Substitute P=6000, r=6 and I=1800 in the above formula.

$1800=\frac{6000\times 6\times t}{100}$

$1800=\frac{36000t}{100}$

$1800=360t$

Divide both sides by 360.

$\frac{1800}{360}=t$

$5=t$

Therefore the total interest will $1800 after 5 years.

Find the equation of all tangent lines having slope of -1 that are tangent to the curve y=(9)/(x+1)

fredd [130]

Answer:

$f(x)=\frac9{x+1}\\ f'(x)=-\frac9{(x+1)^2}\\ f'(x)=-1\ \iff\ -\frac9{(x+1)^2}=-1\ \to \ \frac9{(x+1)^2}=1\ \to \ (x+1)^2=9\\ |x+1|=3\ \to \ x+1=3\ \vee\ x+1=-3\\ x_1=2\ \vee\ x_2=-4\\ f(x_1)=f(2)=\frac9{2+1}=3\\ f(x_2)=f(-4)=\frac9{-4+1}=-3$

First tangent line:

$y=f'(x_1)\cdot (x-x_1)+f(x_1)\ \to \ y=-1(x-2)+3\ \to \ y=-x+5$

Second tangent line:

$y=f'(x_2)\cdot (x-x_2)+f(x_2)\ \to \ y=-1(x+4)-3\ \to \ y=-x-7$

Notice: slope of -1 means that both $f'(x_1), \ f'(x_2)$ are equal to -1, so $f'(x_1)=-1 \ and \ f'(x_2)=-1$
