Answer:
The answer would be A. 1 1/5
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Step-by-step explanation:
An expression becomes an equation by adding an equal sign to the end of the expression and if there's a number on the other side of the equation. For example, 4+3 becomes an equation if you put 4+3=7. Or, 4+3=2+5. Good luck!
It should be 78.11 because you have to subtract 7% from 83.99
hopefully this helps :)
Answer:
The equation for height is
Step-by-step explanation:
we are given
An iron ball is bobbing up and down on the end of a spring
So, height function must be trigonometric in nature
So, we can use formula
now, we can find A , B and D
Calculation of A:
maximum height 46 inch
minimum height =18 inch
so,
Calculation of B:
It takes the ball 2 seconds to go from its maximum height to its minimum height
So, half of time period is 2 sec
now, we can use period formula
we can find B
Calculation of D:
Max=46
min=18
now, we can plug these values into formula
and we get
