Let's calculate r of this G.P: (-20)/(4) = - 5(100)/(-20) = - 5So r = -5
The formula to find the nth term of a GP is;
a(n) = a(r)ⁿ⁻¹
<u />a₆ = a(r)⁶⁻¹
a₆ = 4(-5)⁵ = -12500<u />
Answer:
To find angle y you subtract the two angles form 180 degrees because it is a straight line. Then you subtract angle y and 72 from 180 because a triangle adds up to 180 degrees and you get angle x.
Hope this helps, ask if you have any more questions!
Answer:
represents the radius (in cm) of a circle whose circumference is 15 cm
if 
, then a represents the circumference (in cm) of a circle whose radius is 15cm
Step-by-step explanation:
In a circle the following relationship can be posed:
Let g be a function that determines the radius of the circle from the value of its circumference, so, you have:
Thus, represents the radius (in cm) of a circle whose circumference is 15 cm. You have to 
.
On the other hand, if , then 
represents the circumference (in cm) of a circle whose radius is 15cm. You have to

Answer:
b. (0,-3) (1,-5) (-1,-1)
Step-by-step explanation:
we only have to replace the first part of the parenthesis by x and the second part by y, and see if equality is met
y = -2x - 3
a.
(0,-3) (-1,-4) (-1,-5)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
-4 = -2(-1) - 3
-4 = 2 -3
-4 = -1
WRONG OPTION
b.
(0,-3) (1,-5) (-1,-1)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
-5 = -2(1) - 3
-5 = -2 -3
-5 = -5
-1 = -2(-1) -3
-1 = 2 -3
-1 = -1
CORRECT OPTION
c.
(0,-3) (1,4) (-1,-5)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
4 = -2(1) -3
4 = -2 -3
4 = -5
WRONG OPTION
d.
(0,-3) (1,-4) (-1,-5)
y = -2x - 3
-3 = -2(0) -3
-3 = -3
-4 = -2(1) -3
-4 = -2 -3
-4 = -2
WRONG OPTION
