The velocity v(t) of a 140 pound skydiver is approximated by v(t)=140/1.1 *(1−e^24.2t/140) where t is in seconds after jumping from a plane. what is the skydiver's terminal velocity? that is, in terms of the constants of the problem limt t→∞ v(t)= how long after jumping does it take the skydiver to reach 52 percent of the terminal velocity? \

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
