Answer:
root by squares +pie=6.98765
Step-by-step explanation:
Answer:
To solve this problem, we can use a system of equations.
We know the quadratic expression has the form
Using points (1,12) and (4,0), we can form the following system to find a and b.
We need to divide the second equation by -4 and sum both equations
Then, we use this value to find the other variable
<h3>Therefore, the quadratic function that models the situation is</h3>
or
According to this expression, after 2 seconds, the height is 16 feet.
1/3 x + 2 =y , that’s the answer
<h3>#a</h3>
∠XBC= 55°
[ By corresponding angles]
- Corresponding angle are the angles which hold sane relative position as another angle but somewhere else on the figure.
<h3>#b</h3>
∵ XB and XC are equal, ∠XBC=∠BCX
<h3>Now, With angle sum property of triangle: </h3>
