∑3(1/4)ⁿ⁻¹   ==> replace n by consecutive values, starting with 1
ⁿ=¹
f(1) = 3(1/4)⁰ = 3 x 1 (any number raised to o is equal to 1
f(2) = 3(1/4)¹ = 3 x 1/4
f(3) = 3(1/4)² = 3 x (1/4)²
f(4) = 3(1/4)³ = 3 x (1/4)³
f(5) = 3(1/4)⁴ = 3 x (1/4)⁴
And so on and so forth. Then we have found a pattern that is:

f(n) = 3(1/4)ⁿ⁻¹ 
and with this you can find any number providing you know n

Suppose segment PQ has one endpoint at P (0,0). If T (6,3) is a point 3/10 of the way from P to Q, find the coordinates of Q.
mixer [17]

Answer:

Q(20,10)

Step-by-step explanation:

If point T (6,3) is a point 3/10 of the way from P(0,0) to Q(x,y), then

\overrightarrow {PT}=\dfrac{3}{10}\overrightarrow {PQ}.

Find the coordinates of the vectors \overrightarrow {PT},\ \overrightarrow {PQ}:

\overrightarrow {PT}=(6-0,3-0)=(6,3);\\ \\\overrightarrow {PQ}=(x-0,y-0)=(x,y).

Thus,

(6,3)=\dfrac{3}{10}(x,y),\\ \\(x,y)=\dfrac{10}{3}(6,3)=(20,10).

Harrizon [31]

Answer:

\frac{ - 9}{2}  +  \frac{9}{2}  = 0

\frac{55}{3}  +  \frac{8}{3}  =  \frac{63}{3}

\sqrt{ {0}^{2} +  \frac{ {63}^{2} }{3}  }  =  \sqrt{ \frac{3969}{9} }  =  \frac{63}{3}

Schach [20]
You can use the formula
speed=distance/time
20.88=145/x
x=145/20.88
