Question

X³-23x²+142x-120 please send me answer

Answer 1

Answer:

$given \: \: f(x) = x {}^{3} - 23x {}^{2} + 142x - 120 \\ on \: \: x = 1 \: \: the \: \: function \: \: becomes = 1 {}^{3} - 23 \times 1 {}^{2} + 142 \times 1 - 120 \\ 1 - 23 + 142 - 120 = 143 - 143 = 0 \\ it \: \: means \: \: (x - 1) \: \: is \: \: factor \: \: of \: \: this \: \: \: function. \\ now \: \: divide \: \: this \: \: f(x) \: \: with \: \: (x - 1) \\ on \: \: \: splitting \: \: we \: \: get \: \: other \: \: form \: \: of \: \: f(x) \: \: as \: \: (x - 1)(x {}^{2} - 22x + 120) \\ (x - 1)(x {}^{2} - 10x - 12x + 120) \\ (x - 1)(x(x - 10) - 12(x - 10) )^{2} \\ (x - 1)(x - 10)(x - 12) \: \: \: \: ans.$

Hope it will help you.

Answer 2

Goodevening, hope this would be helpful...

Step-by-step explanation:

Rivers flowing into Earth’s gorges create waterfalls that are natural wonders, drawing millions of visitors. But Earth’s largest and most powerful waterfall doesn’t attract many tourists. That’s because it lies beneath the ocean, under the Denmark Strait, which separates Iceland and Greenland.

The waterfall – known as the Denmark Strait cataract – under the Denmark Strait near the southern tip of Greenland – begins 2,000 feet (600 meters) under the ocean surface and plunges to a depth of 10,000 feet (3,000 meters), nearly a 2-mile (3.2 km) drop.

The Denmark Strait cataract is more than 3 times the height of Angel Falls in Venezuela, which is considered Earth’s tallest waterfall (on land). And the Denmark Strait cataract carries an estimated 123 million cubic feet (3.5 million cubic meters) of water per second. That’s equivalent to almost 2,000 Niagara Falls at peak flow.

Angel Falls in Venezuela, the tallest waterfall on land, is 3 times shorter than the Denmark Strait cataract, and Niagara Falls carries 2,000 times less water, even during peak flows. Image via beautifulworld.com.
