a = 10000

r = 0.4 = 4/10 = 2/5

a_9 = ar^8 = 10000 × 2^8/5^8

a_9 = 10000 × 256/(25 × 25 × 25 × 25)

a_9 = 6.5536

Some one help me on this one

The answer is III only, or D. 


We can start to solve this by knowing what the HL theorem means. The HL theorem, like its name implies, shows says that if a hypotenuse and leg of a triangle are congruent to the hypotenuse and leg of a different triangle, then the triangles are congruent. The only triangle that we see a hypotenuse congruent in is in figure III. In figure II, those congruent sides are both legs while in figure I we just see 2 congruent angles. Now in figure III, we can also see that two legs are congruent because of the reflexive property. That means that the answer is III, or D.

svp [43]

Answer:

  5 mph

Step-by-step explanation:

The relation between speed, distance, and time is ...

  speed = distance/time

Filling in the given values, we find the speed to be ...

  speed = (1/4 mi)/(1/20 h) = (1/4)(20/1) mi/h = 5 mi/h

Elena's speed is 5 miles per hour.
