A school located due south of a park is 2.6 miles due east of a lake, as shown in the map. Which expression represents the dista
timurjin [86]

Answer:

The answer to your question is   2.6 tan 40  miles    

Step-by-step explanation:

To solve this problem use trigonometric functions

We must look for a trigonometric function that relates the opposite side (distance from the school to the park) and the adjacent side (distance from the lake to the school).

This trigonometric function is tangent

                    tan 40 = \frac{opposite side}{adjacent side}

Solve for Opposite side

             Opposite side = Adjacent side tan 40

Substitution

                            dSP = 2.6 tan 40

Please help! i can’t write the equation on here so look at the picture.
Anvisha [2.4K]

Answer:

So if x= 1 , y= -20 , z = -5 , we just have to replace those values on the equation

\frac{\sqrt{yz}}{(z-x)^{2}  + y } =  \frac{\sqrt{(-20) * (-5)}}{(-5-1)^{2}  + (-20) } =  \frac{\sqrt{100}}{(-6)^{2}  -20 }  = \frac{10}{16} =\frac{5}{8}

The area rug in your living room is 5 feet longer than it is wide. If the rug is
Romashka-Z-Leto [24]

Answer:

length = 17 ft and width = 12 ft

Step-by-step explanation:

The rug is rectangular .

Let

width = a

length = a + 5

Area of the rug = a × (a + 5) = a² + 5a

The rug is always placed 2 ft from the wall. The illustration describes a rectangle place into another. The space between the rug and the wall is 100 ft².  

The living room

length = a + 5 + 2 + 2= a + 9

width  = a + 2 + 2 = a + 4

area = (a + 9)(a + 4) = a² + 4a + 9a + 36 = a² + 13a + 36

a² + 13a + 36 - (a² + 5a) = 100

a² + 13a + 36 - a² - 5a = 100

8a + 36 = 100

8a = 100 - 36

8a = 64

a = 64/8

a = 8

Dimension of the living room

length = a + 9

length = 8 + 9 = 17 ft

width  = a + 4

width = 8 + 4 = 12 ft

length = 17 ft and width = 12 ft
