Everett is 6 ft in tall and casts a shadow 10 ft long. A flag pole next to him casts a shadow of 19 ft. How tall is the flag pole?

Answer:

21

Step-by-step explanation:

Answer:

3 x 21.50= 64.50

3 x 7.96= 23.88

3 x 14.99= 44.97

Altogether equals  133.35

400-133.35= 266.65

Answer:

3 x 21.50= 64.50

3 x 7.96= 23.88

3 x 14.99= 44.97

Altogether equals  133.35

400-133.35= 266.65

Answer:

6 to the 21st power

Step-by-step explanation:

Answer:

diagonal is 11.14 cm

Step-by-step explanation:

We start by writing the equation for the width (w) in terms of the length (L):

w = 2 L - 8

from the area = w * L = 62

we replace w in it:    w * L = (2 L -8) * L = 62

2 L^2 - 8 L = 62

2 L^2 - 8 L - 62 = 0

extract 2 common factor:

2 (L^2 - 4 L - 31) = 0

Using quadratic formula we get:

[tex]L=\frac{4+/-\sqrt{4^2-4(1)(-31)} }{2} \\L=\frac{4+/-\sqrt{140} }{2}\\L=7.916\\or\\L=-3.916[/tex]

So, we pick the positive answer L = 7.916 cm

Then we now know the with of the rectangle as well:

w = 2 * L - 8 = 2 * 7.916 - 8 = 7.832  cm

Now we estimate the diagonal of the rectangle using the Pythagorean theorem:

[tex]diag=\sqrt{7.916^2+7.832^2}\approx11.1356\,\,cm[/tex]

which rounded to two decimal places is 11.14 cm

Answer:

  C, D

Step-by-step explanation:

This equation can be solved any of several ways. One that doesn't require much thought is using the quadratic formula.

For ax² +bx +c = 0, the solutions are ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In the given equation, a=2, b=11, c=5, so this becomes ...

  [tex]x=\dfrac{-11\pm\sqrt{11^2-4\cdot2\cdot5}}{2\cdot2}=\dfrac{-11\pm\sqrt{81}}{4}\\\\x=\dfrac{-11\pm9}{4}=\left\{-\dfrac{20}{4},-\dfrac{2}{4}\right\}=\{-5,-\frac{1}{2}\}[/tex]

The solutions are ...

  C. x = -5

  D. x = -1/2

My personal favorite is using a graphing calculator. The solutions are the x-intercepts of the expression on the left. That is, where its value is zero, as the equation says.

Answer:

+-1, +-2,+-5, +-10

Step-by-step explanation:

you first find all the numbers that can go into the constant which is 10, so negative and positive 1 can go into 10, negative and positive 2 can go into 10 etc.

The possible rational roots of the polynomial equation

[tex]1,-1} , +\frac{1}{2} , -\frac{1}{2} , +2,-2, +5,-5, +\frac{5}{2} ,-\frac{5}{2} ,+10,-10[/tex]

Given :

The polynomial equation is

[tex]2x^{9}-3x^{7}+11x+10=0[/tex]

To find out possible rational roots, we use rational root theorem

Rational root of the form

[tex]\frac{p}{q}[/tex] where p is the constant and q is the leading coefficient

p=10  and q=2

Lets write all the factors of 10  and 2

Factors of 10 are 1,2,5,10

factor of 2 are 1,2

Rational root of the form

[tex]+- factors of \frac{p}{q} =+-\frac{1,2,5,10}{1,2}[/tex]

We consider both positive and negative factors. Ignore the repeated roots

So possible rational roots are

[tex]1,-1} , +\frac{1}{2} , -\frac{1}{2} , +2,-2, +5,-5, +\frac{5}{2} ,-\frac{5}{2} ,+10,-10[/tex]

The average of 20 numbers is zero. Of them, at the most, how many may be greater than zero? Average of 20 numbers = 0. Therefore Sum of 20 numbers = (0 x 20) = 0 It is quite possible that 19 of these numbers may be positive and if their sum is a, then 20th number is (-a).

Answer:84

Step-by-step explanation:

Since each trinagle's interior angles which is the angles in side the triangle always add up to 180 you could add the 2 given and then subtract by 180 so 48+48 which equals 96 then 180-96 which will give you 84 as x

Answer

48+48+x=180    x=84

Step-by-step explanation:

The sum of the 3 interior angles of a triangle is always the sum of 180 degrees.  

In short, this means that all three angles have to equal up to 180 degrees

48+48=96

180-96=84  x=84

To check your answer add

48+48+84 should equal 180. It does

Answer:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

Step-by-step explanation:

For the perimeter, add all the sides together:

4 + 6 + 3 + 5 + 2 = 20 m

Answer:

Step-by-step explanation: Perimeter of  figure is = sum of all sides

                                                                                    = 6m+3m+5m+2m+4m

                                                                                   = 9m+7m+4m

                                                                                    = 16m+4m

                                                                                    = 20m
