Answer:
amplitude=5
Step-by-step explanation:
y=a sin x
amplitude =|a|
here a=-5
|a|=5
0.45 Isn't Equal To Any Of These Fractions But It Is Equal To 45/100
Answer:
-3
Step-by-step explanation:
2+(-5)
2-5=-3
that is you solve the equation and trace it on the number line
Answer:
about 5.613 seconds
Step-by-step explanation:
Using the quadratic formula to find the value of t when h = 0, we have ...
at² +bt +c = 0
t = (-b±√(b²-4ac))/(2a)
t = (-72±√(72² -4(-16)(100)))/(2(-16))
t = (-72±√11584)/-32 = (9±√181)/4
Only the positive value of t is of interest.
The coin will hit the stream after (9+√181)/4 seconds ≈ 5.613 seconds.
Step-by-step explanation:
To find the slope you use the slope formula which is y2-y2/x2-x1
And to find the y intercept you use y=mx +b. Yous substitute the slope as m and you substitute a point from the line to find b. Which is the y intercept
