<h2>Answer = </h2><h2>=  \frac{1}{y {}^{5} x {}^{2} }</h2>

Step-by-step explanation:

Greetings !

simplify for variable y first

apply exponent rule

a {}^{b} .a {}^{c}  = a {}^{b +c \\   } \\  y {}^{ - 8}y {}^{5}  = y {}^{ - 8 + 3}

Add/subtract the numbers -8+3=5

= y {}^{5}

Apply exponent rule

a {}^{ - b}  =  \frac{1}{a {}^{b} }

Thus,

y {}^{ - 5}  =  \frac{1}{y {}^{5} }

secondly, simplify for the variable x

Apply exponent rule as we made on y

x {}^{ - 2}

x  {}^{ - 2}  =  \frac{1}{x {}^{2} }

multiply bot the values we get

Hope it helps!

Use distanc formula
distance betwen ponts (x1,y1) and (x2,y2) is
D=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}


distance from art to gass is
from (6,1) to (4,4)
input to find
D=\sqrt{(4-6)^{2}+(4-1)^{2}}=√13

distance from cemetary to animal is
from (3,-4) to (6,-2)
D=\sqrt{(6-3)^{2}+(-2-(-4))^{2}}=√13

how does √13 compare with√13
they are equal




compare dissacne betwen police and stadium then police and art

police to stadium is
(0,-4) to (-2,3)
D=\sqrt{(-2-0)^{2}+(3-(-4))^{2}}=√53= aprox 7.28011

police to art is
(0,-4) to (6,1)
D=\sqrt{(6-0)^{2}+(1-(-4))^{2}}=√61= aprox 7.81025



from police to art is longer by (7.81025-7.28011=0.53015) 0.53015 units

What is the median of 76, 84, 93, 67, 82, 87, and 76?
Ahat [919]
The median of a set of numbers is the midpoint of the set if you were to organize the numbers from least to greatest or greatest to least. So, all we have to do is rearrange the numbers from least to greatest and find the midpoint:
67   76   76   82   84   87   93
count 3 in from both sides and the remaining number is 82, which is the median.

The explicit rule for a sequence and one of the specific terms is given. Find the position of the given term.
baherus [9]

Answer:

14

Step-by-step explanation:

Given :

f(n) = 3.75n − 27.5

f(n) = 25

Put f(n) = 25 in the equation :

25 = 3.75n - 27.5

25 + 27.5 = 3.75n

52.5 = 3.75n

52.5 / 3 75 = n

14 = n

The position of the term is 14
