The two hexagonal pyramids are similar.

spayn [35]

Answer: The approximate surface area of the larger pyramid is 159.31 ft².

Step-by-step explanation:

A pyramid is a solid,

And, When two solids are similar then the ratio of their surface area is the square of the scale factor of similarity.

Here, the scale factor of similarity

$=\frac{\text{Height of larger pyramid}}{\text{Height of smaller pyramid}}$

$=\frac{15}{6}$

Thus, by the above property,

$\frac{\text{ The surface area of larger pyramid}}{\text{The surface area of the smaller pyramid}}=(\frac{15}{6})^2$

It is given that, the smaller pyramid has a surface area of 25.49 ft²,

$\implies \frac{\text{ The surface area of larger pyramid}}{25.49}=\frac{225}{36}$

$\text{ The surface area of larger pyramid} = \frac{25.49\times 225}{36}$

$=\frac{5735.25}{36}$

$=159.3125\approx 159.31\text{ square ft}$

Laura is graphing an absolute-value function in the form

Ilya [14]

Answer:

The equation of the function is;

y = |x-3| -3

Step-by-step explanation:

Here, we want to give the absolute-value function

For the minimum value to be -3, it means that k is negative

since the domain is the set of all real numbers, then we do not have any undefined value for the range y

So, the equation is ;

y = |x-3| - 3
