Answer:

The length of the slide is 10 feet.

Step-by-step explanation:

To find the length of the slide you have to use the formula:

a^2 + b^2 = c^2 (^2 means squared)

In this case:

a= 6 and b=8 c= unknown

6 squared (6 times 6) is 36

8 squared (8 times 8) is 64

Add these two numbers to get:

36+64=100

6^2+8^2=100

However, the length of the slide in not 100 feet. In order to find the correct length you must find the square root of 100. Which is 10.

What number times itself equals 100? 10.

The length of the slide in 10 feet.

12,963 rounded to the nearest hundredth

ladessa [460]

9514 1404 393

Answer:

12,963.00 (in the US)
12,96 (some other places)

Step-by-step explanation:

In the US, a decimal point is represented by a period. This value is interpreted as an integer with no fractional part, so the fractional part is zero:

12,963.00

Some other places, a comma is used to identify the beginning of the decimal fraction. In that form, this number has a fractional part that has 3 as its thousandths digit. The value of 3 is less than 5, so the number is simply truncated at the hundredths place.

12,96

If the thousandths digit were 5 or greater, then 1 hundredth would be added to the truncated number.

Answer: 5.18 pound per square inch

Step-by-step explanation:

According to pressure law, the pressure of a gas is directly proportional to the temperature

P1/T1 = P2/T2

where P1 is the initial pressure = 6 pounds

T1 is the initial to temperatures = 440°F

P2 is the final pressure = Z

T2 is the final temperature = 380°F

Thus, let final pressure be Z

P1/T1 = P2/T2

6/440 = Z/380

0.0136 = Z/380

Make Z the subject formula

Z = 380 x 0.0136

Z = 5.18 pound per square inch

Thus, the final pressure at 380°F is 5.18 psi (pound per square inch)

The inequality boils down to

|y| > y

By definition of absolute value, we have

• |y| = y if y ≥ 0

• |y| = -y if y < 0

So if y ≥ 0, we have

y > y

but this is a contradiction.

On the other hand, if y < 0, we have

-y > y ==> 2y < 0 ==> y < 0

and no contradiction.

Now replace y with (x + 1)/(x - 1) + 1. Then you're left with solving

(x + 1)/(x - 1) + 1 < 0

(x + 1 + x - 1)/(x - 1) < 0

2x/(x - 1) < 0

The left side is negative if either 2x > 0 and x - 1 < 0, or 2x < 0 and x - 1 > 0. The first case reduces to x > 0 and x < 1, or 0 < x < 1. In the second case, we get x < 0 and x > 1, but x cannot satisfy both conditions, so we throw this case out.
