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.

the ratio of boys to girls at the beach cleanup was 7:8. If there were 43 boys, how many girls were there?
faltersainse [42]
I'm pretty sure there were 48 girls at the beach clean up. 43 ÷ 7 = 6.14 (6 cause there's not gonna be floating males with missing body parts). So we multiply 6 x 8 and we get 48.

svp [43]

Answer:

x= 1/2

Step-by-step explanation:

6x+9=12

Step 1: Subtract 9 from both sides.

6x+9−9=12−9

6x=3

Step 2: Divide both sides by 6.

6x/6= 3 /6

And Your Answer Will Be:

x= 1/2

Help timed test! At which root does the graph...
Anastaziya [24]

Answer:

x = -2

Step-by-step explanation:

The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.

(x - 5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)^2 has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

To find where it will touch the axis set the factor equal to zero and solve.

(x + 2) = 0

subtract 2 from both sides

x = -2
