To calculate the velocity, we use the given expression above which is <span>s(t) = −16t^2 + 144. First, we calculate the time it takes to reach the ground. Then, differentiate the expression and substitute time to the differentiated expression.
</span>s(t) = −16t^2 + 144
0 = -16t^2 + 144
t = 3
s'(t) = v = -32t
v = -32(3)
v = -96
Note: negative sign signifies that the object is going down
Answer:
they are congruent so 47 is also the measurement for its corresponding angle(aka the corner that doesn't have a variable)
and in a triangle, interior angles add to 180 so 47+x+y=180
90 + 43 = 133
+47= 180
so your answer is a

6/42 = n/7
Multiply by 7.
42/42 = n.
n = 1.
numerator = 42.
7 is the distance from school to his aunt
44/5=8.5
8.5-1.5=7
