I can't imagine why the variable in the exponent isn't 'n'.
To me, that's the only way this makes sense, and I'm
going to handle it as if the exponent is (n - 1) .
First term: n = 1
A(1) = -2 · 5¹⁻¹ = -2 · 5⁰ = -2 · 1 = -2 .
Fourth term: n = 4
A(4) = -2 · 5⁴⁻¹ = -2 · 5³ = -2 · 125 = -250 .
Eighth term: n = 8
A(8) = -2 · 5⁸⁻¹ = -2 · 5⁷ = -2 · 78,125 = -156,250 .
The first choice on the list looks like the correct one.
Plot all points on the coordinate plane and combine these points by lines to get triangle ABC (see attached picture for details).
Write the equation of side AB:
To find y-intercept you have to substitute x=0, then:
The point 
is the point where line AB intersects y-axis.
Just count the number of zeros and move the decimal that many times . (ex: 7x100= 700 or 7x100.= 7.000
The answer is 48 you basically just do 8 times 6 if I’m right.
Answer:
angle 5 is 61°
angle 7 is 61°
Step-by-step explanation:
1. angle 7 + angle 8 = 90° Because they are complementary angles
2. Because of point 1 above, angle 5 + angle 6 = 90°
3. since given angle 6 = 29°
so, angle 5 = 90° - 29° = 61°
4. since given angle 5 = angle 8
so, angle 8 = 61°
5. from point 1 above,
angle 7 + 61° = 90°
so angle 7 = 29°
