You drop a ball from a height of 0.5 meters. Each curved path has 52% of the height of the previous path. a. Write a rule for th
Verizon [17]

Answer:

a) a_n = 50 (0.52) ^ {n-1}

b) a_6 = 50 (0.52) ^ 5 = 1.90\ cm

Step-by-step explanation:

If each curved path has 52% of the previous height this means that \frac{a_{n+1}}{a_n} = 0.52

Then the radius of convergence is 0.52 and this is a geometric series.

The geometric series have the form:

a_n = a_1 (r) ^ {n-1}

Where

a_1 is the first term of the series and r is the radius of convergence.

In this problem

a_1 = 0.5 meters = 50 cm

r = 0.52

a) Then the rule for the sequence is:

a_n = 50 (0.52) ^ {n-1}

b) we must calculate a_6

a_6 = 50 (0.52) ^ 6-1\\\\a_6 = 50 (0.52) ^ 5 = 1.90\ cm

What are the values of x and y?
tresset_1 [31]

Step-by-step explanation:

y is easy.

it is the Hypotenuse (baseline) of the small right-angled triangle created by the height (8) of the main triangle, the segment 6 of the main Hypotenuse and y.

so, Pythagoras :

y² = 8² + 6² = 64 + 36 = 100

y = 10

x is a bit more complex.

I think the easiest way to get it is to know that the height of a right-angled triangle to the Hypotenuse is the square root of the product of both segments of the Hypotenuse.

so, if we call the segments of the Hypotenuse a and b with a = 6, we have

x = a + b = 6 + b

height (8) = sqrt(a×b) = sqrt(6b)

therefore,

6b = height² = 8² = 64

b = 64/6 = 32/3 = 10 2/3 = 10.66666666...

so,

x = 6 + 10.66666... = 16.666666666...

round it to what is needed. e.g. 2 positions after the decimal point (hundredths) ? then it would be 10.67
