Not a function because of the vertical line test.
Domain is [-2,∞] since the left most point is -2 and the right is unbounded.
Range is (-∞,∞) since it is not bounded in terms of y.

A square pyramid and a cube have the same surface area don’t of each side of the base of the Square pyramid is 10 feet the width
o-na [289]

Answer:

The lateral height of the square pyramid is 5.8\ ft

Step-by-step explanation:

step 1

Find the surface area of the cube

The surface area of the cube is equal to

SA=6b^{2}

where

b is the length side of the cube

w have

b=6\ ft

substitute

SA=6(6^{2})=216\ ft^{2}

step 2

Find the lateral height of the square pyramid

we know that

the surface area of the square pyramid  is equal to

SA=B+4(\frac{1}{2}bh)

where

B is the area of the base

b is the base of the lateral triangle (base of the square)

h is the lateral height of the square pyramid

B=(10^{2})=100\ ft^{2}

SA=216\ ft^{2} -----> is the same surface that the cube

b=10\ ft

substitute the values and solve for h

216=100+4(\frac{1}{2}*(10)*h)

216-100=20h

h=116/20=5.8\ ft

9. Which property is illustrated by (6 x 5) x 4 =6 x (5 x 4)?
Advocard [28]

For this case we have that by definition:

(a * b) * c = a * (b * c)

Indicates an example of the associative property of multiplication.

(6 * 5) * 4 = 6 * (5 * 4)\\30 * 4 = 6 * 20\\120 = 120

Similarly, we observe the associative property of multiplication

Answer:

associative property of multiplication
