Answer #3 is correct

6 is the common ratio (r)
first term is -2/3 (a)
the general equation is f(x)=a(r)^x-1
so plug in the number
f(x)=-2/3(6)^x-1

2√m^2 if m is greater than or equal to 0

iris [78.8K]

Answer:

$\displaystyle \boxed{|2m| }$

Step-by-step explanation:

we are given that

$\displaystyle 2 \sqrt{ {m}^{2} }$

since m is greater than or equal to 0 it's a positive number therefore, the square root of m is defined and recall that √x²=|x| thus

$\displaystyle \boxed{2 |m|}$

remember that,|a|•|x|=|ax| hence,

$\displaystyle \boxed{ |2m|}$

and we're done!

At the mall, buying a pair of shoes and buying a book are independent events.The probability that a shopper buys shoes is 0.15.

IRISSAK [1]

Answer:

The probability that a shopper buys shoes and a book is 0.015

Step-by-step explanation:

we are given

The probability that a shopper buys shoes is 0.15

so, we have

$p(s)=0.15$

The probability that a shopper buys a book is 0.10

so, we have

$p(b)=0.10$

the probability that a shopper buys shoes and a book can be written as

p(s∩b)

we are given that

s and b are independent

so,

p(s∩b) $=p(s)\times p(b)$

now, we can plug values

p(s∩b) $=0.15\times 0.10$

p(s∩b) $=0.015$

What is the distance between the points (-4,0) and (-7, -14) ?

vlada-n [284]

Answer:

Step-by-step explanation:

(-4,0) ; (-7, -14)

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(-7-[-4])^{2}+(-14-0)^{2}}\\\\ =\sqrt{(-7+4)^{2}+(-14)^{2}}\\\\=\sqrt{(-3)^{2}+(-14)^{2}}\\\\=\sqrt{9+196} \\\\=\sqrt{205} \\\\=14.3178$
