In a certain town there were 171 robberies last year. This year the number of robberies has gone down 39%. How many robberies were there this year, to the nearest whole number?

104 robberies

Step-by-step explanation:

No of robberies last year = 171

Robberies for this year reduced by 39%

Percentage robberies of this year reduced to 39%

39% * 171

= 39/100 * 171

= 66.09

That is to say that this year robberies reduced by 66.09

Therefore this year robberies = 171 - 66.09

= 104.31

= 104 to the nearest

whole number

NOTE: don't forget to put the approximation sign in the final answer

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.

-4, -2, 1, 4

domain = x values

range = y values
