What is the solution of log, 729= 3? Of 18 81

1 answer:

5 0

Answer:
Solution
Step-by-step explanation:
Rewrite logx729= 3 is an exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)= y is equivalent to b^y = x.
X^3 = 729
Take cube root on both side and we get
x= 3√729
now we firstly simplify the 3√729
Rewrite 729 as 9^3
x = 3√9^3
pull terms out from under the redical, assuming positive real numbers
x=9
verify each of the solution by substituting them into logx729=3 and solving.
x= 9

a student played a computer game 500 times and won 370 of these game. he then won the next "x" games and lost none. he has now w

a_sh-v [17]

So, this is a proportion problem. If we express 75% as a fraction (3/4ths), we have:

$\frac{370+x}{500+x}=\frac{3}{4}$

Since he won all of his games, we add the number won (x), to the number previously won and divide it by the total games played which is just the previous games played plus the number of current games played, so since he lost no games we still add x to the denominator as well. Solving this gives us:

$4(370+x)=3(500+x) \implies\\ 1480+4x=1500+3x \implies \\ x=20$

That x value is 20.

Write an expression describing all the angles that are coterminal with 141°.

MA_775_DIABLO [31]

<span>The coterminal angles of angle A are given by adding k times 360° to it, where k is an integer, positive or negative. Similarly, all angles that are coterminal with 141° are given by 141° + k * 360° where k is a positive or negative integer. That is 141° + 360°, 141 + 2*360° , 141+3*360° and so on and 141° - 360°, 141° -2*360°, 141° - 3*360° and so on. 9720)</span>
