Answer:

Step-by-step explanation:

y=(x+5)2−1

Use the vertex form,

y=a(x−h)2+k, to determine the values of a, h, and .a=1h=−5k=−1Find the vertex(h,k(−5,−1)

The radii of earth and Pluto are 6,371 kilometers and 1161 kilometers, respectively. Approximately how many spheres the size of

miskamm [114]

Answer:

165

Step-by-step explanation:

Here we have to use the ratio.

Both earth and Pluto are in similar shapes.

To find the number of sphere the size of Pluto does it take to have the same volume, we need to divide the earth's volume by Pluto's volume.

= Earth's volume/Pluto's volume

= 4/3 π (6371)^3 ÷ 4/3 π (1161)^3

Cancelling out 4/3 π both in the numerator and in the denominator, we get

= (6371)^3 ÷ (1161)^3

= 258596602811 ÷ 1564936281

= 165.24

Approximately 165 spheres the size of Pluto to cover the earth volume.

Thank you.

An architect built a scale model of a shopping mall. On the model, a circular fountain is 27 inches tall and 63 inches in diamet

Rasek [7]

The actual fountain is 6 ft tall.....1 ft = 12 inches...so 6 ft = (12 * 6) = 72 inches

72/27 = 2 2/3....u have a scale factor of 2 2/3 (or 8/3)

so the diameter will be :
63 * 2 2/3 =
63 * 8/3 =
504/3 =
168 inches.....12 inches = 1 ft...so 168 inches = (168/12) = 14 ft <==

Chile plans to add about 40,404 square kilometers of national parkland. Suppose a single piece of land is 40,404 square kilomete

9966 [12]

Answer:

The length of the diagonal is 284 km

Explanation:

1- we get the side length of the side:

We are given that the land has a square shape and an area of 40,404 km²

Area of square = (side)²

40,404 = (side)²

side = +√40,404

side = 201.007 km ≈ 201 km

2- we get the length of the diagonal:

Refer to the attach picture representing the area of land.

We can infer that the two side lengths along with the diagonal of the land form a right-angled triangle.

Therefore, to get the diagonal, we can apply the Pythagorean theorem as follows:

$Diagonal = \sqrt{(201)^2+(201)^2}$

Diagonal = 284.2 ≈ 284 km

Hope this helps :)
