Answer:
∠B =
Step-by-step explanation:
Given : a=7 b=10 and C is a right triangle
solution :
refer the attached figure .
Since ΔACB is right angled triangle so we will use trigonometric ratios .

Perpendicular = b =10
Base=a=7
Putting value in formula:




Thus ∠B =
Answer:
Step-by-step explanation:
Answer:
y=log_(6)x
Step-by-step explanation:
From the definition of logarithm:
<---> 
In our case, we have

which means that b=6, therefore the inverse function is

which can be rewritten by switching x and y:

Answer:
Step-by-step explanation:
Domain= All real numbers. To get this answer i just plug the x-values into the quadratic formula to get the y-output.
Maximum area=1323/8
Range= y<= 1323/8
