The height ,h, in feet of a baseball that is popped up into the air is a quadratic function of the time, t, in seconds, since it was hit. an equation that may model this situation is h(t)=4+60t-16t^2. answers the following questions accurately, rounding to two decimals places when needed. how high is the ball when it strikes the bat?

Step-by-step explanation:

The exercise provides you the following Quadratic function:

Then, based on the information given in the exercise, you can conclude that, when the ball strikes the bat, the time in seconds is the following:

Therefore, in order to calculate the height in feet of the ball when it strikes the bat, you need to subsititute into the function and    then evaluate.

Then, you get this result:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
