A tree of 14 m height is broken by the wind so that its top
touches the ground and makes an angle 60° with the ground. Find
the length of the broken part of the tree.

Answer:

QR = 14.00 cm to the neatest hundredth.

Step-by-step explanation:

This is a right triangle with < P = 90.

So QR is the hypotenuse.

< Q is the angle opposite to the line PR.

sin Q = opposite/hypotenuse = PR/QR

sin 40 = 9/QR

QR = 9/sin40

= 14.002 cm.

[tex]\text{Endpoints of diameter,}~~ A(4,6)~ \text{and}~ B(-3,-1)\\\\\text{Diameter,}~AB = \sqrt{(4+3)^2+(6+1)^2}\\\\~~~~~~~~~~~~~~~~~~~=\sqrt{7^2+7^2}\\\\~~~~~~~~~~~~~~~~~~~=7\sqrt2\\\\\text{So , radius}~ = \dfrac{AB}2 = \dfrac{7\sqrt 2}2 =4.9~\text{units.}\\\\\text{Hence the answer is B.}[/tex]

Step-by-step explanation:

Using the formula:

Sin☆=Perpendicular ÷ Hypotenus

Sin☆ = 35 ÷ 48

Sin☆ = 0.7291666667

☆ = Sin^-1 (0.7291666667)

☆ =46.8165782066

where ☆= Degree.

Hence final answer is 46.816

Answer:

the difference of the numbers are 217 and 55.

Step-by-step explanation:

a+b=272

a/b=3…52

a=3b+52

4b+52=272

4b=220

b=55

a=272-55=217

Answer:

5

Step-by-step explanation:

[tex]\frac{2}{3} +\frac{1}{6}= \frac{ }{6} \\[/tex]

Here LCM will be 6. (We made the denominator same)

so, now the equation will be :

[tex]\frac{2}{3}+\frac{1}{6} \\\\ =\frac{4}{6} + \frac{1}{6}[/tex]

= 5/6

So, the value in the red box is 5.

Hope it helps!

Answer:

a) growth

b) 3%

c) 6 years (since the beginning of the decade)

Step-by-step explanation:

Given:

The population P (in thousands) of Austin, Texas during a recent decade can be approximated by [tex]y=494.29(1.03)^t[/tex] when t is the number of years since the beginning of the decade.

General form of an exponential function: [tex]y=ab^x[/tex]

where:

If [tex]b > 1[/tex] then it is an increasing function

If [tex]0 < b < 1[/tex] then it is a decreasing function

a) The model represents exponential growth as 1.03 > 1

b) The annual percent increase of the population is 3%

1.03 - 1 = 0.03

0.03 x 100 = 3%

c) To estimate when was population about 590,000 set y = 590 and solve for t:

[tex]\implies 590=494.29(1.03)^t[/tex]

[tex]\implies \dfrac{590}{494.29}=(1.03)^t[/tex]

Take natural logs of both sides:

[tex]\implies \ln\left(\dfrac{590}{494.29}\right)=\ln (1.03)^t[/tex]

[tex]\implies \ln\left(\dfrac{590}{494.29}\right)=t\ln (1.03)[/tex]

[tex]\implies t=\dfrac{\ln\left(\dfrac{590}{494.29}\right)}{\ln (1.03)}[/tex]

[tex]\implies t=5.988069001...[/tex]

Therefore the population was about 590,000 6 years since the beginning of the decade.

Answer:

108.8yd²

Step-by-step explanation:

Area of a Side Angle Side triangle : Area = 1/2 ( a × b ) × sin(c)

where a and b = the side lengths and c = the angle

Here the given side lengths are 23yds and 9.5yds and the angle given has a measure of 85° so a = 23, b = 9.5 and c = 85

Area = = 1/2 ( a × b ) × sin(c)

a = 23 , b = 9.5 and c = 85

Area = 1/2 ( 23 × 9.5 ) × sin(85)

==> multiply 23 and 9.5

Area = 1/2 ( 218.5 ) × sin(85)

==> multiply 1/2 and 218.5

Area = 109.25 × sin(85)

==> multiply sin(85) and 109.25

Area = 108.8yd²

Note: When the triangle is not a right triangle ( when there is no 90° angle ) we have to use a special formula in order to find the area. Here this is given a side an angle and a side, when given a side an angle and another side you can solve using the formula Area = 1/2 ( a × b ) × sin(c)

Answer:

  13. x=11; MN=65°; NP=115°; NQP=245°

  15. x=9; AD=108°; BC=23°; DC=139°; DBC=221°

Step-by-step explanation:

The marked arcs are congruent, so we can equate the given expressions for their measures:

  10x -45 = 6x -1

  4x = 44 . . . . . . . . . add 45-6x

  x = 11 . . . . . . . . . . divide by 4

The arc measures are found by using the value of x in the corresponding expression. Arcs around a circle total 360°.

  arc MN = (10(11) -45)° = 65°

  arc NP = 180° -65° = 115°

  arc NQP = 360° -NP = 245°

__

The sum of arcs around a circle is 360°. We can use this fact to write an equation involving the given expressions. Clockwise from A, we have ...

  90 +(2x +5) +(17x -14) +12x = 360

  31x = 279 . . . . . . . subtract 81, collect terms

  x = 9 . . . . . . . . . divide by 31

The arc measures are found by using the value of x in the corresponding expression.

 arc AD = 12(9)° = 108°

  arc BC = (2(9) +5)° = 23°

  arc DC = (17(9) -14)° = 139°

  arc DBC = 360° -DC = 221°

Answer:

Step-by-step explanation:

The experimental probability of choosing Grace is 13.6% (17/125*100)

The theoretical probability of choosing Grace is 16.67% (1/6)

Each probability would change because they depend on the data set so if the data set changes, that means the probability will also change depending on the amount it changes.

Answer: A= 42 degrees

Step-by-step explanation:

A= 180-90-48=42 (degrees)

Answer:

A= 42 degrees

a = 27

c= 40.4

Step-by-step explanation:

48 - 90 = 42 (we know the remaining angle area is 90 because its a right triangle and a traingle is 180 degrees)

to find the answer of a we need to use tan(48) and when you convert that to radians you get 1.1106 ish tan is opposite over adjacent and we know the opposite is 30 but we dont know a so we put [tex]\frac{30}{a}[/tex] = 1.1106 and put a on both sides so you divide 30 by 1.1106 and dget 27.0124 and round to the nearest tenth to get 27

to find c you need to find the hypotanuse which is [tex]a^{2}[/tex]+[tex]b^{2} =c^{2}[/tex]

30 squared is 900 add that to 27 squared which is 729 and you get 1629

find the square root of 1629 to get 40.3608 and then round that to the nearest tentth to get 40.4

Answer:

355 miles

Step-by-step explanation:

Figure out how far the car travelled in 1 hour - 3 hours can be divided by 3 for 1 hour, so do the same for the miles - 213 / 3 = 71 miles.

So we know the car travelled 71 miles in 1 hour.

Now just multiply the miles by 5 to figure out the answer - 71 * 5 = 355 miles

Step-by-step explanation:

The volume of the solid whose base is a circle centered at the origin with a radius r is 16r³/3 cubed unit.

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form, with the value of center point in the coordinate plane and measure of radius.

The equation of the circle can be given as,

[tex]x^2+y^2=r^2[/tex]

Here, (r) is the radius of the circle.

Rewrite this equation as,

[tex]y^2=r^2-x^2\\y=\sqrt{r^2-x^2}[/tex]

This will give you the half the length of the side. Thus, the length of the side of the square is,

[tex]s=2y=2\sqrt{r^2-x^2}[/tex]

The area of the square it square of its side. Thus, the area of the square is,

[tex]A(x)=s^2\\A(x)=(2\sqrt{r^2-x^2})^2\\A(x)=4(r^2-x^2})[/tex]

The volume of the solid can be got by integrating the area of the cross-section.

[tex]V=\int\limits {A(x)} \, dx[/tex]

Here, A(x), provides the area of the square at the point x. Thus,

[tex]V=\int\limits {A(x)} \, dx\\V=\int\limits_{-r}^r {4(r^2-x^2)} \, dx\\V=[ {4(r^2x-\dfrac{x^3}{3})}]^r_{-r}\\V= {4(r^2(r)-\dfrac{(r)^3}{3})}- {4(r^2(-r)-\dfrac{(-r)^3}{3})}\\V=4[r^3-\dfrac{r^3}{3}}+ {r^3-\dfrac{r^3}{3}]\\V=\dfrac{16r^3}{3}[/tex]

Thus, the volume of the solid whose base is a circle centered at the origin with a radius r is 16r³/3 cubed unit.
