Answer:
$11.04
Step-by-step explanation:
To calculate the tip, you would find 20% of 55.22 by doing this:
55.2 x 0.20 = ?
You will then get 11.04, and that is the tip.
Hope that helps :>
Answer:
The height of ball is 17 ft at t=0.55 and t=1.14.
Step-by-step explanation:
The general projectile motion is defined as
Where, v is initial velocity and y₀ is initial height.
It is given that the initial height is 7 and the initial upward velocity is 27.
Substitute v=27 and y₀=7 in the above equation to find the model for height of the ball.
The height of ball is 17 ft. Put h(t)=17.
On solving this equation using graphing calculator we get
Therefore the height of ball is 17 ft at t=0.55 and t=1.14.
Answer:
3.5 degrees celcius for first 8 days
To find the lengths of a right triangle, we can use what is called Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse.
13^2 + b^2 = 17^2
169 + b^2 = 289
b^2 = 120
b = 11.0 cm
The length of the other leg of the triangle is 11.0 cm (rounded).
Hope this helps!
Using a linear function, it is found that the costs are given as follows:
- With r rides: C(r) = 20 + 4r.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the price of admission and the price per ride, the y-intercept is of 20 and the slope is of 4, the cost for r rides is given by:
C(r) = 20 + 4r.
Hence, for 6 rides, the cost is given by:
C(6) = 20 + 4 x 6 = $44.
