Answer:
Speed is 171.6 ft/s and distance is 1716 feet
Step-by-step explanation:
Given that,
The speed of a parachute = 117 miles per hour.
1 mph = 1.47 ft/s
117 mph = 171.6 ft/s
We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,
d = vt

Hence, this is the required solution.
Answer:
4+3=3+4
Step-by-step explanation:
The commutative property of addition says that, the order in which you add two real numbers does not matter.
Let
, then
a+b=b+a
From the given options;
4+3=3+4
shows the commutative property of addition
Y = 2x + 12
2(4) + 12 = 8 + 12 = 20
She spends $20
Answer:
A ski lift is modeled by the function f(x) = (0.2)(–2x 3 + 23x 2 + 25x + 50), where x is the time in seconds. When it comes out of the first stop, it is now climbing toward its highest point from the ground. During which time interval will the ski lift reach a height over 50 feet above the ground?
