Answer:
Temp after 6 minutes: 125 degrees Temp after tt minutes: 65 + 10t
Step-by-step explanation:
65 x 10(6) = 125
I think the answer is $113.1. The question was confusing so sorry if it’s wrong.
Answer:
3.81 s
Step-by-step explanation:
Let's consider the following formula that represents the journey of a falling object.
d = 3 t + 5 t²
where,
- d is the distance measured in feet
- t is the time measured in seconds
We can find the time that it will take to travel 84 feet by replacing d = 84 in the equation.
84 = 3 t + 5 t²
5 t² + 3 t - 84 = 0
We have a = 5, b = 3 and c = -84. We apply the second grade solving formula.
x₁ = 3.81 and x₂ = -4.41
Since the time cannot be negative, the answer is t = 3.81 s
The area of a square is the side of the square squared or A= s^2 (s meaning side of the square)
Perimeter or the 4 sides is P= 4 x s
Since the area is 6561, plug that into the area formula so you get 6561= s^2
Next, take the square root of both sides of the equation because that is the opposite of squaring a number)
When you do that you get s = 81
Now that you know s, plug it into the Perimeter formula P= 4 x 81
The perimeter or distance around the park is 324 meters.
