but you can find the area by squaring one side

Answer:

2 + i and + √5

Step-by-step explanation:

Since P(x) is a quartic equation, it has 4 roots.

Since 2 - i and -√5 are two of its roots, then its conjugate pairs of 2 + i and + √5 are its other two roots.

So, its other two roots are 2 + i and + √5

Answer:

39.25 unit²

Step-by-step explanation:

Radius of circle = diameter/2 = 10/2 = 5

Area of a circle = πr²

Area of ½ circle = ½ πr² = ½ x (22/7) x 5²

Area = 39.25 unit^2

Answer:

option B is correct

Step-by-step explanation:

Answer:

20 ft

Step-by-step explanation:

Keep in mind that, both ratios are the same, let the length of the shadow be x, then you can make an equation that 30/ 40 = 15 / x, then 30x = 15 * 40 = 600, so x = 20.

Answer:

Step-by-step explanation:

C = 147 ft.  The relevant formula is C = 2(pi)r, and here C = 147 ft = 2(pi)r.

The relevant area formula is A = (pi)r^2.  If we solve the above formula for r we get

         147 ft

  r = ------------    and so  r^2 (needed to calculate the area) is

           2pi

          147^2 ft^2

r^2 = ------------------

                4(pi)

                                      147^2 ft^2

and so the area is  A = ---------------- = 7203/pi

                                           3 pi

                                                                    C                           C^2

Alternative method:  C = 2pi*r so r = -------------- and r^2 = -------------

                                                                 2 pi                           4pi^2

                                                                               C^2             C^2

then the area of the circle is A = pi(r^2) or pi*-------------- = ---------------

                                                                             4pi^2               4pi

                                                                        (147 ft)^2

and in this case the area of the circle is A = --------------

                                                                              4 pi

or A = 1720 ft^2

Answer:

[tex]v = \frac{5.4mT}{6T - 37}[/tex]

[tex]v = -1.701*10^8[/tex]

Step-by-step explanation:

Given

[tex]T = \frac{37v}{6v-5.4m}[/tex]

Solving (a): Make v the subject

[tex]T = \frac{37v}{6v-5.4m}[/tex]

Cross Multiply:

[tex](6v-5.4m)T = 37v[/tex]

Open bracket

[tex]6vT - 5.4mT = 37v[/tex]

Collect Like terms

[tex]6vT - 37v= 5.4mT[/tex]

Factorize:

[tex](6T - 37)v= 5.4mT[/tex]

Make v the subject

[tex]v = \frac{5.4mT}{6T - 37}[/tex]

Solving (b):

[tex]T = 4.5[/tex]

[tex]m = 7 * 10^7[/tex]

So, the expression becomes:

[tex]v = \frac{5.4mT}{6T - 37}[/tex]

[tex]v = \frac{5.4*7*10^7*4.5}{6*4.5 - 37}[/tex]

[tex]v = \frac{170.1*10^7}{27 - 37}[/tex]

[tex]v = \frac{170.1*10^7}{-10}[/tex]

[tex]v = -17.01*10^7[/tex]

[tex]v = -1.701*10*10^7[/tex]

[tex]v = -1.701*10^8[/tex]

Answer:

12.6ft³

Step-by-step explanation:

Hey There!

So the first thing we need to do is find the formula for volume of a cone

[tex]V=\pi r^{2} \frac{h}{3}[/tex]

r = radius

h = hypotenuse

Now all we have to do is plug in the hypotenuse and the radius

[tex]V=\pi 2^{2} \frac{3}{3}[/tex]

2²=4

[tex]\frac{3}{3} =1[/tex]

4xπ=12.5663706144

And now we just round to the nearest tenth

so we can conclude that the volume of the cone is 12.6ft³

Answer:

The length is 30 cubic yards.

Step-by-step explanation:

To find volume you use equation V=LxWxH

Since we already know the height, width, and volume we can input them into the equation.

18,720=L x 24 x 26

As you can see, the length is still unknown.

To figure it out though, you can multiply the height and width of the prism,

24 x 26 = 624

And then divide the volume, 18,720 by it.

18,720/624 = 30

Thus, your length is 30 cubic yards.
