AD and BC are diameters of Circle P. What is the length of

Alekssandra [29.7K]

Answer:

$\widehat {AC} =19.54\:ft$

Step-by-step explanation:

$\widehat {AC} = \frac{\theta}{360\degree} \times 2\pi r$

$\widehat {AC} = \frac{(180-40)\degree}{360\degree} \times 2(3.14) (8)$

$\widehat {AC} = \frac{140\degree}{360\degree} \times 2(3.14) (8)$

$\widehat {AC} = \frac{140}{360} \times 2(3.14) (8)$

$\widehat {AC} =19.5377778$

$\widehat {AC} =19.54\:ft$

A tree is broken at a height of 5 meters from the ground and it's top touches the ground existence of 12 m from the base of the

Gelneren [198K]

Answer:

18 m

Step-by-step explanation:

The given situation is equivalent to a right angled triangle as shown in the diagram attached.

AB is the height at which tree was cut.

And the top touches the ground at a point C.

So,

AB = 5 m and

AC = 12 m

Here, we have to find original height of the tree.

Original height of Tree = AB + BC OR AB + BC' (Because B is the point in height AC' of tree)

Let us consider the $\triangle ABC$ .

As per pythagorean theorem:

$\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow BC^{2} = AB^{2} + AC^{2}\\\Rightarrow BC ^2=5^2+12^2\\\Rightarrow BC = \sqrt{169}\\\Rightarrow BC = 13\ m$

Therefore the answer is :

Height of tree = 5+13 = 18 m

The formula for the height of a ball as a function of time is given by the equation h = -16t^2 + vt + h, where h is the height o

yawa3891 [41]

It's really poor form to use 'h' to mean two different things in two different
places in the same formula. Fortunately, we know what you mean.

H = h + vt - 16t²

You have said that ...
initial height = 5 feet
initial velocity = 20 feet per second, no direction given
time = 1 second

Since you gave us the magnitude of the initial velocity but not its direction,
there are a huge number of possibilities. I'll focus only on two of them:
20 feet per second straight down, and 20 feet per second straight up.

Initial velocity is downward:
H = (5) + (-20) (1) - 16 (1)²
H = 5 - 20 - 16 = 5 - 36 = 31 feet underground after 1 second

Initial velocity is upward:
H = (5) + (20) (1) - 16 (1)²
H = 5 + 20 - 16 = 25 - 16 = 9 feet above ground after 1 second
