<u>Answer-</u>

<em>The coordinates of D' are (-1, </em><em>-5</em><em>)</em>

<u>Solution-</u>

The coordinates of D are (-1, 5).

While reflecting any points across the x-axis with coordinates as (x, y) becomes, (x, -y). i.e sign of y-coordinate changes.

The rule is (x, y) → (x, -y)

Applying so, after reflecting point D, its reflection D' will have coordinates as (-1, -5)

Therefore, the y-coordinate is -5.

7. The largest of the Great Pyramids in Egypt was built with a square base,
strojnjashka [21]

Answer:

Difference between the original and current volumes = 4013140.30 cubic feet

Step-by-step explanation:

Largest pyramid has the square base with one edge = 754 feet

Area of the square base = (Side)²

                            = (754)²

                            = 568516 square feet

Volume of the pyramid = \frac{1}{3}(\text{Area of the base})(\text{Height})

                                       = \frac{1}{3}\times 568516\times 481

                                       = 91152065.3 cubic feet

After erosion,

Area of the base = (745)² = 555025 square feet

Volume of the pyramid = \frac{1}{3}(555025)(471)

                                       = 87138925 cubic feet

Difference between the original and current volumes of the pyramid

= 91152065.30 - 87138925

= 4013140.30 cubic feet

Where is the function increasing?<br> A)1 B)3&lt; X C)-infinity &lt; x &lt; 1<br> D)-infinity
eduard

Answer:

A) 1

Step-by-step explanation:

Given:

A graph of a function.

When we analyze the given graph, it is of a <em>parabola</em>.

To find:

The interval of values of x where the function is increasing.

Solution:

First of all, let us learn about the meaning of increasing and decreasing functions.

1. A function y=f(x) is known as increasing  in an interval a when

Value of y keeps on increasing when we move from the value of x from a to b.

2. A function y=f(x) is known as decreasing  in an interval a when

Value of y keeps on decreasing when we move from the value of x from a to b.

On analyzing the given graph , we can see that the graph is decreasing on the interval: -\infty

and is increasing on the interval: 1

When we choose from the options,

The correct answer is option A) 1
