Answer:

-\frac{2197}{3375}\\\mathrm{Decimal:\quad }\:-0.65096

Step-by-step explanation:

-\left(\frac{13}{15}\right)^3\\\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}\\\left(\frac{13}{15}\right)^3=\frac{13^3}{15^3}\\=-\frac{13^3}{15^3}\\13^3=2197\\=-\frac{2197}{15^3}\\15^3=3375\\=-\frac{2197}{3375}

Answer:

=  \frac{ - 2197}{3375}

Step-by-step explanation:

cube =  {x}^{3}  \\  (\frac{ - 13}{15})  ^{3}  \\  \frac{ - 13}{15}  \times  \frac{ - 13}{15}  \times  \frac{ - 13}{15}  \\ \\   =   \frac{ - 2197}{3375}

hope this helps

In a doctor's waiting room, there are 14 seats in a row. Eight people are waiting to be seated. Three of the 8 are in one family
lianna [129]
There are 14 chairs and  8 people to be seated. But among the 8. three will be seated together:

So 5 people and (3) could be considered as 6 entities:

Since the order matters, we have to use permutation:

¹⁴P₆ = (14!)/(14-6)! = 2,162,160, But the family composed of 3 people can permute among them in 3! ways or 6 ways. So the total number of permutation will be ¹⁴P₆  x 3! 

2,162,160 x 6 = 12,972,960 ways.

Another way to solve this problem is as follow:

5 + (3) people are considered (for the time being) as 6 entities:

The 1st has a choice among 14 ways
The 2nd has a choice among 13 ways
The 3rd has a choice among 12 ways
The 4th has a choice among 11 ways
The 5th has a choice among 10 ways
The 6th has a choice among 9ways

So far there are 14x13x12x11x10x9 = 2,162,160 ways
But the 3 (that formed one group) could seat among themselves in 3!
or 6 ways:

Total number of permutation = 2,162,160 x 6 = 12,972,960

Find the surface area of a sphere with a radius of 1. Use 3.14 for π. Round your answer to the nearest tenth.
Butoxors [25]
The formula for finding the surface area of a sphere is A=4πr^{2}. Since we already have the radius, we just plug that into the equation, like so:
A = 4 x 3.14 x 1^{2}
First, following the rules of PEMDAS, do the exponent, coming out with an answer of 1. Now, multiply 4 x 3.14, which is 12.56. 12.56 x 1 = 12.56.
Rounded to the nearest tenth, your answer is 12.6.
Hope this helps!
