Answer:
The value of height of the building h = 509.2 feet
Step-by-step explanation:
From the Δ A B C
⇒ h = y 
° ------- (1)
From Δ A B D
⇒ h = ( y + 300 ) 
° ------- (2)
Equation 1 = Equation 2
⇒ y ° = ( y + 300 ) °
⇒ 0.46 y = 0.36 y + 109.2
⇒ 0.1 y = 109.2
⇒ y = 1092 feet
Put this value of y in equation ( 1 ) we get,
⇒ h = 1092 × tan 25°
⇒ h = 509.2 feet
This is the value of height of the building.

Answer:
the function is EVEN because f(x)= f(-x)
Step-by-step explanation:
Key to find if a function f(x) is even or odd is to replace the x with -x
if the results comes out to be f(x) then it is even function
if the results comes out to be -f(x) then it is odd function
where as graphically even f(x) will be symmetric around the y-axis and odd f(x) will be symmetric around the origin.
In given case f(x)=7
if we replace x with -x in above equation then results is 7
f(-x)= 7
hence f(x)= f(-x) = 7

Answer:
552.6 because 15% × 3684 = 552.6
3684 × 0.15 = 552.6
Answer:
IQR = 3
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box , that is Q₃ = 62.5
Q₁ is the value at the left side of the box. that is Q₁ = 59.5
Then
IQR = Q₃ - Q₁ = 62.5 - 59.5 = 3
