If you would like to know the equation that could be used to find Hannah's age, you can calculate this using the following steps:
h ... Hannah's age ... h = a + 2
a ... Anthony's age ... a = h - 2
a + h = 92
h - 2 + h = 92
2 * h - 2 = 92
2 * h = 92 + 2
2 * h = 94 /2
h = 94 / 2 = 47
<span>a = h - 2 = 47 - 2 = 45
</span>
The correct result could be <span>h - 2 + h = 92.</span>
A.
the starting point is where t=0
d(0)=-16(0)^2+96(0)+112
D(0)=112
started from 112 feet
b. max height is vertex
for
y=ax^2+bx+c
the x value of the vertex is -b/2a
so
D(t)=-16t^2+96t+112
t value of vertex is -96/(2*-16)=3
it reaches after 3 seconds
C. simpliy evaluate D(t) for t=3
D(3)=-16(3)^2+96(3)+112
D(3)=-16(9)+288+112
D(3)=-144+400
D(3)=256
max height is 256ft
5 lb of trail mix* (2.5 oz of chocolate pieces/ 1 lb of trail mix)= 12.5 oz of chocolate pieces.
(Note that the unit cancels out so you get the answer)
The final answer is 12.5 oz of chocolate pieces~
Answer:
a.27
Step-by-step explanation:
Using Pythagoras theorem:
x=sqrt(6^2+26^2)
x=26.683..
By rounding, x=27
