*Silly and/or spam answers will not be tolerated*
stepladder [879]

Answer:

-1/8

Step-by-step explanation:

lim x approaches -6     (sqrt( 10-x) -4) / (x+6)

Rationalize

   (sqrt( 10-x) -4)      (sqrt( 10-x) +4)

    ------------------- * -------------------

       (x+6)                 (sqrt( 10-x) +4)

We know ( a-b) (a+b) = a^2 -b^2

a= ( sqrt(10-x)   b = 4    

(10-x) -16

-------------------

(x+6) (sqrt( 10-x) +4)    

-6-x

-------------------

(x+6) (sqrt( 10-x) +4)

Factor out -1 from the numerator

-1( x+6)

-------------------

(x+6) (sqrt( 10-x) +4)

Cancel x+6 from the numerator and denominator

-1

-------------------

(sqrt( 10-x) +4)

Now take the limit

lim x approaches -6    -1/ (sqrt( 10-x) +4)

                                      -1/ (sqrt( 10- -6) +4)

                                      -1/ (sqrt(16) +4)

                                      -1 /( 4+4)

                                        -1/8

Stolb23 [73]
Given that the metal strip is being installed around a bench that 6ft long 2ft wide. The metal required will be given by:
P=4(L+W)
=4(6+2)
=4(8)
=32 ft
Therefore we conclude that we need a metal strip that is 32ft long

Which has the least value for 9? *
marishachu [46]

Answer:

0.1039

Step-by-step explanation:

Obtain the place value of 9 in each value and choose the smallest :

1.95

9 is the first digit after the decimal point ; which is equal to 0.9 = tenth place

0.1039

9 is the 4th digit after the decimal point ; which is equal to 0.0009 = ten thousandth place

3.092

9 is the second digit after the decimal point ; which is equal to 0.09 = hundredth place

2.009​

9 is the third digit after the decimal point ; which is equal to 0.009 = thousandth place

Hence the smallest value of 9 among the options given resides in 0.1039 (ten thousandth place).
