Answer: 0.04
Step-by-step explanation:
The measurement error is calculated as:
= Error / Ideal value
= (2.5 - 2.4) / 2.5
= 0.1/2.5
= 0.04
Therefore, the correct option is D.
15x - 6 = -9
9(x+2) = 9x+2=11x
9+11x=19x
Right???
Answer:
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
Step-by-step explanation:
Given that,
A ball is thrown vertically upward. After t seconds its height is given by the function

where h is height in feet.
Maximum value:
Given function f(x)= at²+bt+c.
- Find the value
- Putting
in the given function. - The maximum value of the given function is
.
Here a= -16 , b=56 and c=0
The ball attains its maximum height when
s.
Putting the value of t in the given function

=49 feet
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
An exponential function is a function in which the independent variable is an exponent. Exponential functions have the general form y = f (x) = ax, where a > 0, a≠1, and x is any real number. The reason a > 0 is that if it is negative, the function is undefined for -1 < x < 1.
It may be the last one......................................... but i'm not sure.
