Answer:
10.3% or so
Step-by-step explanation:
Just divide the number you want to figure out what percentage it is (3) by the total number (29) and take the decimal for your percentage and round if needed.
(3/29)
Answer:
3) 441 m² (C)
Step-by-step explanation:
the square root of 29² - 20² is = 21 (side length of Q
21 is all of the side lengths since it's a square.
so multiply 21 by itself:
21x21= the area of q= 441 m²
(A)
Solve for the first variable in one of the equations, then substitute the result into the other equation.
v=3
w=−7
(B)
Solve for the first variable in one of the equations, then substitute the result into the other equation.
t=11/6
u=1/9

Rates of change are the change of a quantity over another.
The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
The given parameters are:
-- the amplitude
--- the period
The position of the mass is modeled by:
Where:
So, we have:
becomes
Differentiate
When t = 2.1, we have:
Approximate
Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
