The number of passengers using a railway fell from 190,205 to 174,989 during a 5-year period. Find the annual percentage decreas

lakkis [162]

Answer:

1.65%

Step-by-step explanation:

We will assume the percentage was the same over the 5 years. The number of passengers using a railway is expressed by the formula

$P(t) = P_{o}(1 - r)^{t}$

Where

P(t) is the number of passengers after 5 years

P(t) = 174,989

P₀ is the number of the passengers at the beginning of the period

P₀ = 190,205

r is the rate in percentage r = ?

t is time duration t = 5 years

Substituting these given values into the formula,

$174,989 = 190,205(1 - r)^{5}$

$(1 - r)^{5} = \frac {174,989}{190,205}$

$1 - r = \sqrt[5]{ \frac {174,989}{190,205}}$

$1 - r = \sqrt[5]{0.920}$

$1 - r = 0.9835$

$r = 1 - 0.9835$

$r = 0.0165$

r = 1.65%

The annual percentage decrease over the period of 5 years is 1.65%

5. Two vertices of a rectangle are (8,-5) and (8,7). If the area of the rectangle is 72 square units, name the possible location

Phantasy [73]

Answer:

<u>Given vertices:</u>

(8, -5) and (8, 7)

These have same x-coordinate, so when connected form a vertical segment.

<u>The length of the segment is:</u>

7 - (-5) = 12 units

The area of the rectangle is 72 square units, so the horizontal segment has the length of:

72/12 = 6 units

<u>Possible location of the remaining vertices (to the left from the given):</u>

(8 - 6, -5) = (2, -5)

and

(8 - 6, 7) = (2, 7)

<u>Similarly to previous exercise:</u>

(5, -8) and (5, 4) given with the area of 48 square units

<u>The distance between the given vertices:</u>

4 - (-8) = 12 units

<u>The other side length is:</u>

48/12 = 4 units

<u>Possible location of the other vertices (to the right from the given):</u>

(5 + 4, -8) = (9, -8)

and

(5 + 4, 4) = (9, 4)
