A ladder 15 feet long leans against the top of a structure at a 60 degree angle to the ground. What is the height of the buildin
Goshia [24]

Answer:

height of the building is 12.99 feet.

Step-by-step explanation:

given, try to analyse:

  • ladder 15 feet long.
  • 60 degree angle to the ground.

the height of the building is opposite to the angle 60° and given hypotenuse, the ladder of 15 feet long.

using sine rule:

sin(x) = \frac{opposite}{hypotenuse}

sin(60) = \frac{opposite}{15}

opposite = sin(60) *15

opposite = 12.99feet

Therefore the height of the building is 12.99 feet.

Determine the length and midpoint of the segment whose endpoints are (–15, 9) and (–4, 11).
ch4aika [34]
(-15,9) \\&#10;x_1=-15 \\&#10;y_1=9 \\ \\&#10;(-4,11) \\&#10;x_2=-4 \\&#10;y_2=11 \\ \\&#10;\hbox{the length:} \\&#10;l=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(-4+15)^2+(11-9)^2}=\\&#10;=\sqrt{11^2+2^2}=\sqrt{121+4}=\sqrt{125}=\sqrt{25 \times 5}=5\sqrt{5} \\ \\&#10;\hbox{the midpoint:} (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}) \\&#10;\frac{x_1+x_2}{2}=\frac{-15-4}{2}=\frac{-19}{2}=-9.5 \\&#10;\frac{y_1+y_2}{2}=\frac{9+11}{2}=\frac{20}{2}=10 \\&#10;(-9.5,10)

The length of the segment is 5√5, the midpoint of the segment is (-9.5,10).

If y is directly proportional to x^2 and y=18 and x=3,
Svetach [21]

Answer:

Step-by-step explanation:

(i)

y=k*x^2\\\\if\ x=3, y=18 ==> 18=k*9\ ==> k=2\\\\Equation\ is:\ y=2x^2\\

(ii)

x=5 ==> y=2*5²=50

(iii)

32=2*x^2\\x^2=16\\x^2-4^2=0\\(x-4)(x+4)=0\\\\x=4\ or\ x=-4\\
