two minutes after a skydiver opens his parachute, he has descended 1,900 feet. after 5 minutes, descended 4,750 feet. if the distance varies directly with the time, at what rate is the skydiver descending?
Answers
4,750 ft/ 5 minutes= 950 ft/minute.
If the distance varies directly with the time, the skydiver is descending at a rate of 950 feet per minute~
4750/5= 950
Why do you do this? Because you are trying to find the amount of ft per minute.

What is Probability?
Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Jana has a number cube numbered 1 to 6.
When Jana rolls the number cube 1 time, there is an equal chance of getting each number.
Probability that the number is 2 = 1/6
So, there is a 1/6 probability that the number rolled is 2.
Jana plans to roll the cube 78 times.
So the number of times Jana will roll a 2 = 78 × (1/ 6) = 13
Hence the number of times that Jana will roll a 2 in the number cube is predicted as 13.

13x2=26
26-4=22
2x2=4
4+4=8
8x-10=-80
-80 - 22 = -102

Final answer:
To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.
Explanation:
To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.
So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.
Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.
