Answer:
Therefore the function that models the height of the object after t seconds is given by "H(t) = 15 + 8.5*t + 16.09*t²".
Step-by-step explanation:
Since the object has a initial velocity and it's being accelerated by gravity, than it's height is defined by:
H(t) = H(0) + V(0)*t + 0.5*g*t²
Applying the data from the problem, we have:
H(t) = 15 + 8.5*t + 0.5*32.17405*t²
H(t) = 15 + 8.5*t + 16.09*t²
Therefore the function that models the height of the object after t seconds is given by "H(t) = 15 + 8.5*t + 16.09*t²".
(4) is the y-intercept in the equation, and is where you plot it on the y-axis. (-3) is your slope. If you were to graph it, here is the link to how it looks like.
Answer:
$13.20 or $2.20
Step-by-step explanation:
Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.
11 x .20 = 2.2
Now the answer depends on what you need the answer to be. if you need the total, it's $13.20.
If you need the tip, it's $2.20.
I believe that the last one is true
because the linear equations are
y=ax+b
which means that the point of y-axis is on one side and the slope, point on x-axis and y-intercept are on the other side
good luck
Answer:
$75.38
Step-by-step explanation:
12 : 100 = x : 79.87
x = 79.87 * 12 / 100
x = 0.7987 * 12
x = 9.5844 = discount
Price = 79.87 - 9.5844 = $ 70.2856
7.25 : 100 = x : 70.2856
x = 70.2856 * 7.25 / 100
x = 70.2856 * 0.0725 = 5.095706 = taxes
final price = 5.095706 + 70.2856 = 75.381306
