The roof of a building is 9 m high. A rope is tied from the roof to a peg on the ground 12 m away from the wall. What is the length of the rope?

Answers

Answer:

15 m

Step-by-step explanation:

Height of buiding h= 9m

Lenght from building l= 12m

let the length of the rope be x=???

Applying Pythagoras theorem

x^2=h^2+l^2

x^2= 9^2+12^2

x^2= 81+144

x^2=225

square both sides

x=√225

x=15 m

Hence the length of the rope is 15 m

Answers

Answer:

C

Step-by-step explanation:

Because lets say we have a point (1,2)

when reflecting this point over the y-axis it becomes (-1,2) so only the sign of the X value changes. Therefore by writing the system f(x)=g(-x) it changes the X value.

The equation was y = 18x + 300.

IF THE VOLUME OF THE BOX BELOW IS
x3 + 6x2 + 9x + 4
AND THE WIDTH OF THE BOX IS x + 4,
THEN FIND THE LENGTH AND HEIGHT OF
THE BOX

Answers

Answer:

The length of the box is (x + 1)

The height of the box is (x + 1)

Step-by-step explanation:

The given function representing the volume of the box is presented as follows;

V = x³ + 6·x² + 9·x + 4

The function representing the width of the box, W = x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1

x³ + 4·x²

    [tex]{}[/tex]  2·x² + 9·x + 4

    [tex]{}[/tex]  2·x² + 8·x

    [tex]{}[/tex]               x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)

The width of the box = (x + 4)

The length of the box = (x + 1)

The height of the box = (x + 1).
