John is adding a curved edge to the landscaping in front of the high school. The curve is an arc of a circle with a radius of 16

8090 [49]

By definition, the arc length is given by:
S = R * theta
Where,
Theta: central angle
R: radio
Substituting the values we have:
S = (1600) * (π / 8)
Rewriting we have:
S = 200π feet
S = 628.3185307 feet
Round to the nearest foot:
S = 628 feet
Answer:
The length of the curve to the nearest foot is 628 feet.

Evaluate log(-13)<br> Correct answer will get brainliest

Sedaia [141]

if given log(a)=b, where no base is stated, we assume base 10, or $log(a)=log_{10}(a)$

also, $log_a(b)=c$ translates to/can be written equivilently as $a^c=b$

therefore, given

$log(-13)=?$ where we want to find ?

assume base 10 and translate

$10^?=-13$

since we cannot raise a positive number to any real power and give a negative number, ? is not a real number and therefore, there are no real solutions

if we do want to find a solution, we can use Euler's idendity

$e^{\pi i}=-1$ where i is the complex number i=√-1 and e is euler's number
