A) is 2x
b) is $x^{3}$
c) is -2x

I think these are correct.
$log_{10}1000^{x] = log_{10}10^{2x}=2x$
I did similar things to get other answers
$1000^{log_{10}x} = 10^{3log_{10}x}=10^{log_{10}x^{3}}=x^{3}$

rjkz [21]

$\bf y=-27(x+4)^3+1\implies 0=-27(x+4)^3+1
\\\\\\
-1=-27(x+4)^3\implies \cfrac{-1}{-27}=(x+4)^3\implies \cfrac{1}{27}=(x+4)^3
\\\\\\
\sqrt[3]{\cfrac{1}{27}}=x+4\implies \cfrac{\sqrt[3]{1}}{\sqrt[3]{27}}=x+4\implies \cfrac{1}{3}=x+4\implies \cfrac{1}{3}-4=x
\\\\\\
-\cfrac{11}{3}=x$

A rectangular soccer field is 80 meters wide and 110 meters long. The coach asks players to run from one corner of the field to

seraphim [82]

Answer:

Step-by-step explanation:

Goven the length of the field = 110m

Width = 80m

The length of the diagonal is expressed using the pythagoras theorem;

d² = l² + w²

d² = 110² + 80²

d² = 12100 + 6400

d² = 18500

d = √18500

d = 136.01

Hence the players have to run 136.01m diagonally
