F(1)=-12, f(n)=2f(n-1) <br> find first 4 terms

amid [387]

<h3>First four terms are: -12, -24, -48, -96</h3>

============================================

Explanation:

The notation f(1) = -12 tells us that the first term is -12.

The equation f(n) = 2*f(n-1) indicates that we're multiplying the (n-1)th term by 2 to get the nth term. Basically we multiply each term by 2 to get the next term.

-12*2 = -24

-24*2 = -48

-48*2 = -96

So the first four terms are -12, -24, -48, -96.

-----------------------------------

Alternative Approach

f(1) = -12 .... first term

f(n) = 2*f(n-1) ... nth term recursive formula

f(2) = 2*f(2-1) ... plug in n = 2

f(2) = 2*f(1)

f(2) = 2*(-12) ... plug in f(1) = -12

f(2) = -24 ... second term

f(n) = 2*f(n-1) .... resetting for the next computation

f(3) = 2*f(3-1) ... plug in n = 3

f(3) = 2*f(2)

f(3) = 2*(-24) ... plug in f(2) = -24

f(3) = -48 .... third term

f(n) = 2*f(n-1) ... one more reset

f(4) = 2*f(4-1) .... plug in n = 4

f(4) = 2*f(3)

f(4) = 2*(-48) ... plug in f(3) = -48

f(4) = -96 ... fourth term

We get the first four terms to be -12, -24, -48, -96, which was the same as earlier.

Angelica uses the point to represent the location of her house and uses the point to represent the location of a gas station. Ea

PilotLPTM [1.2K]

From the graph, angelica's house is represented by the point (4, 3) and the gas station is represented by the point (10, 8).

The distance between two given points in the xy-plane is given by
$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
where:
$(x_1, y_1)=(4, 3) \ and \ (x_2, y_2)=(10, 8)$

Thus
$d= \sqrt{(10-4)^2+(8-3)^2} \\ = \sqrt{6^2+5^2} = \sqrt{36+25} \\ = \sqrt{61} =7.81$

Therefore, the distance of the gas station from Angelica's house is 7.81 miles.
