Answer:
x = 10
Step-by-step explanation:
The arc size (100) is the same size as the central angle (<AOC)
The angle labeled 5x is 1/2 of the central angle.
Since the central angle = 100o the 5x angle = 50 degrees.
5x = 50 Divide by 5
5x/5 = 50/5
x = 10
Im assuming you mean 4 more than 3 times the width so we'll make the width x and the length 3x + 4
perimeter is all of the sides added together so our equation is 2(x) + 2 (3x + 4) because there are two sides for length and two for width. we expand this equation to: 2x + 6x + 8 which equals 8x + 8. this is equal to 18.4 so 8x + 8 = 18.4
subtract each side by 8: 8x = 10.4
divide each side by 8: x = 1.3
if x = 1.3 then the width = 1.3
if the width = 1.3 then the length = 7.9 because 3(1.3) + 4 = 7.9
area is length times width so 1.3 x 7.9 = 10.27
The area is equal to: 10.27
C 9 because 18divid by 2 is 9 and 27 divided by 3 is 9
Answer:
As x-approaches infinity, we get a rational function whose denominator becomes bigger and bigger while the numerator is constant
Step-by-step explanation:
The basic exponential functions are of the form:
where b is a constant.
Horizontal is the horizontal line the graph of a function approaches when as x-values approaches infinity.
For exponential growth functions, as x-approaches negative infinity the function approaches zero, i.e y=0.
For exponential decay functions as x-approaches positive infinity the function approaches zero.
The reason is that, in each case we get a rational expression whose denominator grows bigger and bigger, while the numerator remains constant.
