Set up a ratio between the tree and Enzo.

5 ft / 6ft = x/21 ft.

Cross multiply:

(5 x 21) = (6 x x)

Simplify:

105 = 6x

Divide both sides by 6:

x = 105 / 6

x = 17.5 feet tall.

Answer:

The equation the circle is given by

{\bf 4x}^{\bf 2}+{\bf 4y}^{\bf 2}-{\bf 8x+0y-60}={\bf 0}

Step-by-step explanation:

The general form of the circle is

x^2+y^2+Dx+Ey+F=0\hfill (1)

Given points are (5,0) , (0,4) and (2,4)

Let the points (5,0) , (0,4) and (2,4) be (x_1,y_1) , (x_2,y_2) and (x_3,y_3) respectively

The equation of the circle passes through given points (5,0) , (0,4) and (2,4)

Substituting the point (5,0) in (1)

(-5)^2+(0)^2+D(5)+E(0)+F=0

25-5D+F=0

5D-F=25\hfill (2)

Substituting the point (0,4) in

(0)^2+(4)^2+D(0)+E(4)+F=0

16+4E+F=0

4E+F=-16\hfill (3)

Substituting the point (2,4) in

(2)^2+(4)^2+D(2)+E(4)+F=0

4+16+2D+4E+F=0

2D+4E+F=-20\hfill (4)

By solving the equations (2) ,(3) and(4) we get the values of D,E and F as below

D=-2  , E=0  and F=-15

substituting the values of D,E and F in (1) we get

x^2+y^2-2x+(0)y-15=0

Now multiplying the above equation into 4 we get

4x^2+4y^2-8x+(0)y-60=0

PLEASE HELP ASAP (8)/(27) a^(15) cube of a monomial
vagabundo [1.1K]

Answer:

2/3a^5

Step-by-step explanation:

we know that 2/7x2/7x2/7 = 8/27

a^15  cube will be a^5

because we know (2^3)^2 = 2^6

so (a^5)^3 = a^15

2/3a^5
