<span>a. True
The question is pretty much the entire definition of a radian. For an unit circle, its entire circumference is 2π and the entire circle has 2π radians. A quarter circle, or 90°, or π/2 radians, have 1/4th of the circumference. And 2π/4 is π/2. This natural relationship is WHY higher mathematics uses radians for the measurement of angles rather than arbitrary units such as degrees.</span>
Answer:
(0, -2)
Step-by-step explanation:
The slope equation is written as y = mx + b where m is the slope and b is the y-intercept. In this equation the slope, which is m, is -2/3 and the y-intercept is -2, which is the value of b. So the y-intercept on the graph would be found at point (0, -2)
Answer:
72.2%
Step-by-step explanation:
Given data
Initial price= £245
Final price= £883
% increase= Final - Initial / final *100
% increase=883 - 245 / 245 *100
% increase= 638 / 883 *100
% increase=0.722*100
% increase=72.2%
Hence the increase is 72.2%
Answer:
Step-by-step explanation:
perimeter means that you add up all the sides do the perimeter is 41
8x = 44 -4
8x = 40
x = 40/8
x = 5
