Write an explicit formula for the An, and the n^th term of the sequence 24,-12,6,....
Annette [7]

Answer:

T_n =  -48* (-\frac{1}{2})^{n}

Step-by-step explanation:

Given

24, -12, 6,...

Required

Write a formula

The above sequence shows a geometric sequence because:

r = \frac{-12}{24} = \frac{6}{-12} = -\frac{1}{2} -- common ratio

The equation is determined using:

T_n = ar^{n-1}

Where

a = 24

Substitute values for a and r

T_n = 24* (-\frac{1}{2})^{n-1}

Apply law of indices:

T_n = 24* (-\frac{1}{2})^{n} * (-\frac{1}{2})^{-1}

T_n = 24* (-\frac{1}{2})^{n} * 1/(-\frac{1}{2})

T_n = 24* (-\frac{1}{2})^{n} * 1*-2

T_n =  1*-2*24* (-\frac{1}{2})^{n}

T_n =  -48* (-\frac{1}{2})^{n}

<em>The above represents the explicit formula</em>

Three bags of of potatoes and four cases of corn cost $40. Five bags of potatoes and two cases Of corn cost $34. Find the cost o
TEA [102]
P = potato C = corn

3P + 4C = $40
5P + 2C = $34

Multiply -2 to the 2nd equation to get
-10P - 4C = -68

Add it to the 1st equation

3P + 4C = 40
-10P - 4C = -68
-----------------------
-7P = -28

Solve for P
P = $4

Substitute 4 into P(potato) to find what C(corn) is

In the adjoining figure O is the centre of the circle the tangent to the circle of radius 6 cm from the exterior point P of the
slamgirl [31]

Answer:

Let P be the external point. O be the origin. join O and P get OP and nearest point on the circle from P be A.

Let Q be the point onthe circle  in which, tangent make 90° with radius at Q.

PQ = 8 and OQ = 6

we get a right angled triangle  PQO right angled at Q.

so, OP^2 = OQ^2 + PQ^2= 8^2 + 6^2 = 64 + 36 =1==

therefore OP =10cm

we need nearest point from P, which is PA

PA = OP - OA= 10 -6=4cm
