Answer: im pretty sure you times the inside of the area of the triangle and it should work
Step-by-step explanation:
1) 8
2) 14.5*2=29
3) 7x+5=2*13, 7x+5=26, 7x=21, x=3
4)d(1)=2r,
if r increase 3 times, d(2)=2*(3r)
d(2)/d(1)=(2*3r)/2r=3,
so diameter increases 3 times
Roughly something like this. The y intercept is at (0,1). The x intercept is at (-.5,0). Another point is at (1,3).
Answer:
The dollar bills would encircle earth 65753.1 times
Step-by-step explanation:
We have
Length of dollar bill = 15.5 cm
Total dollar bills = 17 trillion =
Thus the length of 17 trillion dollar bills equals
Now taking shape of earth as a perfect sphere the circumference of earth becomes
Thus the number of times the dollar bills would encircle earth equals
Answer:(theta) =π only
Step-by-step explanation:
-4cos(theta)+1=5
Subtract 1 from both sides
-4cos(theta)+1-1=5-1
-4cos(theta)=4
Divide both sides by -4
-4cos(theta) ➗ -4=4 ➗ -4
cos(theta)=-1
(theta)=cos(inverse)(-1)
(theta)=180
(theta)=π
