Answer:
48 ft
Step-by-step explanation:
For the quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the given quadratic, which defines a parabola opening downward, the axis of symmetry defines the time at which the maximum height is reached.
t = -48/(2(-16)) = 1.5
Then the maximum height is ...
f(1.5) = (-16·1.5 +48)1.5 +12 = (24·1.5) +12
f(1.5) = 48
The maximum height the object will reach is 48 feet.
Answer:
n=6, m=6√3
Step-by-step explanation:
n = Opposite leg = sin(30°)*hypotenuse = (1/2)*12 =6
m= adjacent leg = cos(30°)*hypotenuse =((√3)/2)*12=6√3

Find the solution set for y = 2x + 1, given the replacement set {(-2, -3), (-1, -1), (0, 2), (1, 3), (2, 6)} ...?

We have to plug in the values in the equation:
y = 2 x + 1
- 3 = 2 * ( - 2 ) + 1
- 3 = - 4 + 1
-3 = - 3
-------------------
-1 = - 2 + 1
- 1 = - 1
------------------
3 = 2 * 1 + 1
3 = 2 + 1
3 = 3
------------------
Answer:
The solution set is: { ( -2, 3 ), ( - 1 , 1 ) , ( 1, 3 ) }
