Answer:
1,0472 rad
Step-by-step explanation:
ANGLE MEASURES
Generally two measuring systems are used:
1. The sexagesimal system, whose unit is the degree: º
A sexagesimal degree is the amplitude of the angle resulting from dividing the circumference into 360 equal parts.
2. The radial system whose unit is the radian: rad
A radian is the measure of the center angle of a circle whose arc length coincides with the length of its radius.
<u>CONVERSION OF GRADES TO RADIANS
</u>
To convert an angle of degrees to radians or vice versa, what must be done is a rule of three, considering that:
360° = 2π radians
Calculation
(60° * 2π rad) /360° = 1.0472 rad
Let s be the speed of the boat in still water.
Let c be the speed of the current.
s - c = 48/6 = 8
s + c = 48/4 = 12
Adding the two equations, we get:
2s = 20
s = 10
The answer is 10 miles per hour.

Answer:
c. P= 1/6; a=8
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by
where
P is the initial value or y-intercept (this vale cannot be equal to zero)
a is the base of the exponential function ( in a exponential growth function the value of a is greater than 1)
<u><em>Verify each case</em></u>
case A) P=6; a = 1/8
Is not a exponential growth function, because a < 1 (is a decay exponential function)
case B) P=6; a = 1
Is not a exponential function
case C) P= 1/6; a=8
Is a exponential growth function, because a > 1 and P is not zero
case D) P=1/6; a = 1/8
Is not a exponential growth function, because a < 1 (is a decay exponential function)
Answer:
8;45
Step-by-step explanation:
When you divide 360 by 8, you get 45 degrees, which means the octagon (8 sides) has an angle rotation of 45.
