Answer:
Step-by-step explanation:
The function for this problem is: h(t) = -16(t)^2 + vt + s h= the height t= time v= velocity s= starting height With the information given, we know that the starting height is 0, since it was from the ground, and the velocity of the ball is 35 feet per second. Inserting the these information into the equation, we get: h(t) = -16(t)^2 + 35t Now the question asks to find the maximum height. It can be done by using a grapher to graph the maximum of the parabola. It could also be done by finding the vertex, which would be the maximum, of the graph by using x= -b/(2a), where b is equal to 35 and a is equal to -16. We get x=35/32, the x-value of where the vertex lies. You can use this value as the t-value in the previous equation to find the h-value of the vertex. When you do, you get h= 19.1 feet, or answer D.

9. Draw a model with 3x4 model and shade in 9 squares; say its 75%
Answer:
35x.08
Step-by-step explanation:
35x.08 equals 2.8 which means there is a tax of $2.08 so your total would be $37.08
We can see that the two triangles share an angle and all their sides are parallel, thus by Tales theorem, they are in Tales position, which proves that they are congruent.
we can see from figure that:
call x and y the unknown segments TA and TN, then we have:
3.3/(3.3 + x) = 6/8
8*3.3 = 6(3.3 + x)
x = 1.1
and then the proportion still holds for those sides as well as AN and RI
we also have:
y/(y + 1.6) = 6/8
8y = 6y + 9.6
y = 4.8
<span>and then the proportion still holds for those sides as well as AN and RI</span>
