write the equation from the statement

this is the equation
now we can solve for x where x is the size of the table

Answer:
100
Step-by-step explanation:
f(n+1)=-10 f(n)
f(1)=1
put n=1
f(2)=-10f(1)=-10×1=-10
put n=2
f(3)=-10f(2)=-10×-10=100
Answer:
You first work out the radius, as below:
Area = pi x radius^2
=> radius = sqrt(Area/pi)
Then, you find out circumference C.
=> C = 2 x pi x radius
Hope this helps!

1) Speed is measured in distance units divided by time units, such as miles per hour. Here, you're given the number of miles traveled and the number of hours it takes, so you can figure tha average speed to be
... speed (or "rate of change") = distance/time = 165 mi/(3 h) = 55 mi/h
2) "speed at the moment" 1.5 hours into the flight means ...
... d. an instantaneous rate of change at 1.5
3) To keep their average speed on target, the dragons must travel at higher than their average speed for a while.
Answer:
1:2
Step-by-step explanation:
25:50 can be simplified down to 1:2. Think about ratios like fractions, since 25 can be divided into 50 two times, 25 is 1/2 of 50.
