Answer:He worked for 4 hours
Explanation:
The vertices of △XYZ are X(4, 5), Y(4, 13), and Z(8, 9). Find an equation of the circle circumscribed about △XYZ.
An equation is ???
NEEED HELPPP PLEASEEE
Answer:
The equation of the circle is (x - 4)² + (y - 9)² = 4²
Explanation:
The center radius form of the equation of the circle is (x - h)² + (y - k)² = r²
Therefore, given the coordinates of the vertices of the inscribed triangle, we have points on the circumference includes;
X(4, 5), Y(4, 13), Z(8, 9)
Hence, we have;
(4 - h)² + (5 - k)² = r² = h²- 8·h - 10·k + k² + 41..........(1)
(4 - h)² + (13 - k)² = r² = h² - 8·h + k² - 26·k +185.....(2)
(8 - h)² + (9 - k)² = r² = h² - 16·h -18·k + k² +145.........(3)
Subtracting equation (1) from (2), we have;
-(16·k -144) = 0
∴ 16 k = 144
k = 9
Subtracting equation (1) from (3), we have;
-(8·h + 8·k - 104) = 0
Which gives;
8·h + 8·k - 104 = 0, where k = 9 gives
8·h + 8×9 - 104 = 0
8·h - 32 = 0
h = 32/8 = 4
Plugging in the values of h and k in equation (3), we have;
(8 - 4)² + (9 - 9)² = r²
4² = r²
∴ r = 4
The equation of the circle is (x - 4)² + (y - 9)² = 4².

Which characterization accurately describes BOTH regular fossils and index fossils?
Answer:A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata.
Answer:
A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. A index fossil must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, Zone fossil is used when the fossil have all the characters stated above except wide geographical distribution, they are limited to a zone and can't be used for correlations of strata.
Explanation:
I really hope that helped. I don't know much about fossils though.

Lucinda has 9 ounces of flour. A batch of cupcakes requires 1/3 ounce of flour. A batch of muffins requires 1/4 ounce of flour. How many more batches of muffins than batches of cupcakes can Lucinda make with her flour?
Answer:
9 more muffins
Explanation:
Lucinda has 9 ounces of flour.
To make a cupcake she requires 1/3 ounce of flour, therefore the number of cupcakes she can make from 9 ounces of flour can be given by:
(1/3)x = 9 where x is the number of cupcakes.
Therefore, x = 9 × 3 = 27 cupcakes
To make a muffin she requires 1/4 ounce of flour, therefore the number of muffins she can make from 9 ounces of flour can be given by:
(1/4)y = 9 where y is the number of muffins.
Therefore, y = 9 × 4 = 36 muffins
The number of more muffins she can make more than cupcakes from her flour = 36 - 27 = 9 more muffins
Answer:
15more batches
Explanation:
9 divided by 1/3 = 27
9 divided by 3/4 = 12
27- 12 = 15

What are the major physical characteristics of the Asian continent? Provide an example of each type of landform.
Answer:
Explanation:
The Asian continent is home to diverse landscapes including deserts, mountains, and tropical paradises. The Gobi desert in China and Mongolia is the largest desert in Asia. The Himalayan mountains in India, Bhutan, Nepal, and Pakistan is the largest mountain range in the world. Hong Kong City in Hong Kong (or disputed territory of China) is considered one of the most beautiful tropical cities representing the diverse culture of the Chinese.
Answer:
The sheer size of the Asian continent subdivides it into several sections with distinct physical characteristics. Asia divides into Central Asia, South Asia, Southeast Asia, North Asia, and East Asia. Its landforms include peninsulas, mountains, plateaus, plains, deserts, and islands. Asia also has four peninsulas, one of which is Korea. The Himalayas and Urals are some of Asia’s most well-known mountain ranges, and the Himalayas are the world’s tallest. The Tibetan Plateau rests in Asia. The Ganges Plain houses a very large percentage of the world’s population. East Asia is home to the largest Asian desert, the Gobi Desert. Sri Lanka is a famous island.
