A tree 12m high is broken by the wind in such a way that its top touches the ground and makes an angle 60° with the ground. at w

Katena32 [7]

The height of broken part of tree from ground is 5.569m.

Justification:

Let BD is a tree of height 12 m.

Suppose it got bent at a point C and let the part CD take the position CA, meeting the ground at A.

i.e., CD = AC = h m

Broken part makes 60° angle from ground

So, ∠BAC = 60°

Now, height of remaining part of tree = (12 – h)m.

In right angled ∆ABC,

sin 60° = BC/AC

⇒ √3/2 = (12 - h)/h

⇒ √3h = 2(12 – h)

⇒ √3h = 24 – 2h

⇒ √3h + 2h = 24

⇒ h(√3 + 2) = 24

⇒ h(1.732 + 2) = 24

⇒ h(3.732) = 24

⇒ h = 24/3.732 = 6.4308 m

Hence, height of broken tree from ground

⇒ BC = 12 – h

⇒ 12 – 6.4308 = 5.569m

Hence, tree is broken 5.569 m from ground.

My little sister need help with this problem. Annabelle arranged her 42 building blocks into 3 rows of 14 blocks. Then, she rear

Tcecarenko [31]

Annabelle could arrange her blocks in one row of 42 building blocks as 1 times 42 = 42.

She could also arrange her blocks in 2 rows of 21 blocks because 2 times 21 is also 42.

In 1994, the moose population in a park was measured to be 3000. By 1998, the population was measured

dem82 [27]

Answer:

P(t) = 100t +2600

4100 in 2005

Step-by-step explanation:

You are given two points for (year, population) = (t, p):

(4, 3000), (8, 3400)

It is useful to use the two-point form of the equation for a line.

p = (p2 -p1)/(t2 -t1)(t -t1) +p1

p = (3400 -3000)/(8 -4)(t -4) +3000

p = 400/4(t -4) +3000

p = 100t +2600

P(t) = 100t +2600 . . . . written in functional form

In 2005, the population is predicted to be ...

P(15) = 100×15 +2600 = 4100

Margaret makes bracelets and sells them to tourists. the function s(t) approximates how many bracelets margaret makes per hour.

Fantom [35]

The units for the composite function s(w(h)) is bracelets over a week when the function s(t) approximates how many bangles Margaret makes per hour and the function w(h) represents how many hours per week Margaret spends making the bracelets.

To define the unit of the composite function s(w(h)), we first need to find the units of the functions s(t) and w(h).

The function s(t) represents the number of bangles per hour, so its unit will be bangles over an hour.

The function w(h) represents the hours per week spent on making the bracelets, so its unit will be hours over a week.

Now, we can define the unit of the composite function s(w(h)).

To find the unit of the composite function we follow these steps:-

s(w(h)),

= s(hours over a week) {replacing the function w(h) by its units},

= (bangles over an hour(hours over a week)) {replacing the function s(t) with its units},

= bangles over a week {Simplifying}.

Thus, the units for the composite function s(w(h)) is bracelets over a week when the function s(t) approximates how many bangles Margaret makes per hour and the function w(h) represents how many hours per week Margaret spends making the bracelets.

Can I get help on this one

ivann1987 [24]

Answer:

150

Step-by-step explanation:

The angle as a whole is 180 degrees. 150 and 30 are supplementary angles because they add up to equal 180.
