Properties of Logs
logb(x/y) = log<span>bx</span> - log<span>by</span>.
therefore
log5 (4/7)= log5 (4)- log5 (7)
<span>Solve log 5 (4) and log 5 (7) with the base change of the logarithm</span>
<span>log 5 4 = log 4 / log 5 </span>
Use the calculator:
<span>
<span>log 5 4 =0.8613531161
</span></span>
log 5 7 = log 7 / log 5
<span>log 5 7 =1.2090619551</span>
<span>log5 (4/7)= log5
(4)- log5 (7)=-0.347708839</span>
Answer:
Because the line is the shortest path between 2 points
86 feet
Assuming the court is rectangular in shape then
area = length × width
length = area / width = 
= 86 feet
Answer: it is an exponential decay function
Step-by-step explanation:
Since 0.3 is less than 1 then increasing the value of the x will lead to the decrease of the value function y
