Explanation:
Acceleration can be found by dividing the change in velocity by the time.
(<em>v </em>is the final velocity, <em>u</em> is the initial velocity, <em>t </em>is the time).
The velocity increased from 22 m/s to 236 m/s in 5 seconds. Therefore:
Substitute the values into the formula.
Subtract in the numerator.
- 236 m/s-22 m/s=214 m/s
Divide.
The acceleration of the object is <u>42.8 meters per square second.</u>
Answer:
The answer is below
Explanation:
Given that f(x) = x√3.
A function can be vertically stretched or compressed by multiplying it by a positive constant. If the constant is greater than 1, it is vertically stretched and if the constant is less than 1 it is vertically compressed.
If a function f(x) = x is compressed or stretched by a constant a, then the new function g(x) = a f(x)
If a function f(x) = x is translated a units down, then the new function g(x) = f(x) - a
If a function f(x) = x is translated a units left, then the new function g(x) = f(x-a)
If f(x) = x√3 is compressed vertically by a factor of 1/3. The new function is
If it is then translated 3 units left and 7 units down, the transformed function g(x) is:
