A(n)=ar^(n-1) and we can find the rate upon using the ratio of two points...
50/1250=1250r^2/1250r^0
1/25=r^2
r=1/5 so
a(n)=1250(1/5)^1=250
...
You could have also found the geometric mean which is actually quite efficient too...
The geometric mean is equal to the product of a set of elements raised to the 1/n the power where n is the number of multiplicands...in this case:
gm=(1250*50)^(1/2)=250
Answer:
See below
Step-by-step explanation:
You have not provided the options.
But I will explain how you can work it.
Coterminal angles are two or more angles that have the same terminal side in standard.
If you want to find an angle that is coterminal with 98°, you keep adding or subtracting 360°.


Therefore 488°, 818°, -262° are examples of angles that are coterminal with 98°
Answer:
B. 2.75 mph
Step-by-step explanation:
If it took him 2 hours to walk 5.5 miles, 5.5 ÷ 2 = 2.75, which is what he walked in a single hour, meaning he was walking 2.75 mph
