A civil engineer is mapping the overhead clearance of his family’s property on a coordinate grid. The ground is represented by t

he x-axis and the base of the house is at the origin. There are two trees on the property. One tree is 10 feet from the base of the house and is 14 feet tall. The other tree is 13 feet from the base of the house and is 9 feet tall. What is the distance from the base of the house to the closest treetop? Round your answer to the nearest tenth.

We are given
x1 = 10 ft
y1 = 14 ft
x2 = 13 ft
y2 = 9 ft

We are asked to find the distance between the base of the house to the closest treetop.

So,
d1 = √(10² + 14²) = 17.20
d2 √(13² + 9²) = 15.81

The distance is 15.81 ft to the closest treetop which is the tree 13 feet from the base of the house.

Answer:

15.8 feet

Step-by-step explanation:

The base of the house is at the origin.  This makes the ordered pair representing it (0, 0).

The top of the shorter tree is represented by the ordered pair (13, 9).  The top of the taller tree is represented by the ordered pair (10, 14).

We will use the distance formula for each.

For the shorter tree:

d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\=\sqrt{(9-0)^2+(13-0)^2}\\\\=\sqrt{9^2+13^2}\\\\=\sqrt{81+169}\\\\=\sqrt{250}\approx 15.8

For the taller tree:

d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\=\sqrt{(14-0)^2+(10-0)^2}\\\\=\sqrt{14^2+10^2}\\\\=\sqrt{196+100}\\\\=\sqrt{296}\approx 17.2

The smaller distance is 15.8.

You are dealt two cards successfuly without replacement from a shuffled deck of 52 playing card. Find the probability that first
katen-ka-za [31]

The simplified expression is (\frac{4}{663})

Step-by-step explanation:

Here, the total number of cards in a given deck = 52

let E : Event of drawing a first card which is King

Total number of kings in the given deck = 4

So, P(E) = \frac{\textrm{The total number of king}}{\textrm{The total number of cards}} = \frac{4}{52}  = (\frac{1}{13} )

Now, as the picked card is NOT REPLACED,

So, now the total number of cards = 52 - 1 = 51

Total number of queen in the deck is same as before = 13

let K : Event of drawing a second card which is queen

So, P(K) = \frac{\textrm{The total number of queen}}{\textrm{The total number of cards}} = (\frac{4}{51}  )

Now, the combined probability of picking first card as king and second as queen  = P(E) x P(K)  = (\frac{1}{13}) \times(\frac{4}{51}) = (\frac{4}{663} )

Hence, the simplified expression is (\frac{4}{663})
