Answer:

- 13.077

Step-by-step explanation:

Here we have to calculate the square root of a certain number using the help of the calculator or a square root table.

The given expression is $- \sqrt{ 171 }$ .

Now, using calculator $\sqrt{ 171 } = 13.076696$

Now, $- \sqrt{ 171 } = - 13.076696$

miss Akunina [59]

Answer:

The volume of the pyramid is $V=187\ ft^{3}$

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base of the pyramid

H is the height of the pyramid

we have

$B=93.5\ ft^{2}$

$H=6\ ft$

substitute

$V=\frac{1}{3}(93.5)(6)=187\ ft^{3}$

Find the equation of the ellipse with the following properties.

zalisa [80]

Equation of an ellipse:

(x-h)²/a² + (y-k)²/b² = 1
Since it passes through the origin (0,0) , then h = k = 0 hence the equation:
(x-0)²/a² + (y-0)²/b² = 1
x²/a² + y²/b² = 1

2a = major axis = 2.|5| + |-5| = 10. then a = 5 and a² = 25
2b = minor axis = 2.|3| + |-3| = 6. then b = 3 and b² = 9

Then the final equation is:
x²/25 + y²/9 = 1
