Answer:
x = 23.1
Step-by-step explanation:
The parallel lines make the left segments proportional to the right segments. This lets us write the equation ...
x/14 = 33/20
Multiplying by 14, we get ...
x = 14(33/20) = 7(33/10) = 23.1
Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
Answer:
A) The slope of a line is basically the steepness of it or it can be defined as the change in y for a unit change in x along the line.
B) -1
Step-by-step explanation:
The point here are ( -2,6 ) and ( 0,4 ).
Here 
,
And 
,
Answer:
c
Step-by-step explanation:
Answer:
<em>Subtract 225 from both sides. You have a
2 (or b
2
) =
400
. Square root on both sides. Therefore, a
2
(or b
2
), i.e. the other leg, is </em>
<em>20 cm.</em>
