f(n) = (3)n − 1; f(5) = 81
f(n) = 4(3)n + 1; f(5) = 2,916
f(n) = 4(3)n; f(5) = 972
f(n) = 4(3)n − 1; f(5) = 324
Answer:
answer is C f(n) = 4(3)n; f(5) = 972
Step-by-step explanation:

The graph is an illustration of an exponential function
The true statement is (d) [tex]\mathbf{f(n) = 4(3)^{n-1}}[/tex], [tex]\mathbf{f(5) = 324}[/tex]
An exponential function is represented as:
[tex]y = ab^{x-1}[/tex]
From the graph, we have the following points
[tex](x_1,y_1) = (1,4)[/tex]
[tex](x_2,y_2) = (2,12)[/tex]
So, we have:
[tex]y = ab^{x-1}[/tex] --------- [tex](x_1,y_1) = (1,4)[/tex]
[tex]4 = ab^{1-1}[/tex]
[tex]4 =ab^0[/tex]
[tex]4 =a \times 1[/tex]
[tex]4 =a[/tex]
[tex]a = 4[/tex]
[tex]y = ab^{x-1}[/tex] --------- [tex](x_2,y_2) = (2,12)[/tex]
[tex]12 = ab^{2-1[/tex]
[tex]12 = ab[/tex]
Substitute [tex]a = 4[/tex]
[tex]12 = 4b[/tex]
Divide both sides by 4
[tex]3 = b[/tex]
[tex]b =3[/tex]
Recall that:
[tex]y = ab^{x-1}[/tex]
So, we have::
[tex]y = 4(3)^{x-1}[/tex]
Express as a function of n
[tex]\mathbf{f(n) = 4(3)^{n-1}}[/tex]
Substitute 5 for n, to calculate the 5th term
[tex]\mathbf{f(5) = 4(3)^{5-1}}[/tex]
[tex]\mathbf{f(5) = 4(3)^4}[/tex]
[tex]\mathbf{f(5) = 324}[/tex]
Hence, option (d) is correct

Noah bought 4 tacos and paid $6. At this rate, how many tacos could he buy for $15?
Answer:
10
Step-by-step explanation:
each taco is 1.50$ 15$ divided by 1.50$ is 10
Answer:
He can buy 10 tacos with $15.
Step-by-step explanation:
You can do a cross multiplication process. Think in this way:
If he buys 4 tacos for $6, then how many tacos can he get in $15? When you do the cross multiplication process, you'll find that he can get 10 tacos with $15.

Triangle GHJ with vertices G(-2,4), H(3,6), and J(3,-2) is dilated by a factor of centered at the origin. What are the coordinates of G' after the dilation? 63,4) (2,4) . 3) O 12 2 3 3 3 (3,-4)
Answer:
The answer would most likely be the second one because that one makes the most sense here.
Step-by-step explanation:
When a triangle is dilated, the size of the triangle changes.
The coordinate of G' after dilation is: (a) [tex]\mathbf{(-\frac 23,\frac 43)}[/tex]
The vertices are given as:
[tex]\mathbf{G = (-2,4)}[/tex]
[tex]\mathbf{H = (3,6)}[/tex]
[tex]\mathbf{J = (3,-2)}[/tex]
The scale factor (k) is given as:
[tex]\mathbf{k =\frac 13}[/tex]
So, the image of G is calculated as:
[tex]\mathbf{G' = k \times G}[/tex]
This gives:
[tex]\mathbf{G' = \frac 13 \times (-2,4)}[/tex]
[tex]\mathbf{G' = (-\frac 23,\frac 43)}[/tex]
Hence, the coordinate of G' after dilation is: (a) [tex]\mathbf{(-\frac 23,\frac 43)}[/tex]
