Step-by-step explanation:
f(x) = 
The parabola opens up, so has a minimum at the vertex.
Let (h, k) be the vertex
h = -b/2a = - (-144)/2(1) = 57
k = 57^2 - 144(57) = 3249 - 6498 = -3249
Therefore, the vertex is (57, -3249)
The minimum value is -3249
The domain is the set of real numbers.
The range = {y | y ≥ -3249}
The function decreases when -∞ < x < 57 and increases when 57 > x > ∞
The x - intercepts:
= 0
x(x - 114x) = 0
x = 0 or x = 114
x-intercepts are (0, 0) and (0, 114)
When x = 0, then we get the y-intercept. So, 0^2 - 114(0) = 0
y-intercept is (0, 0)
4p - 9 = -193
4p = -193 = 9
4p = -184
p = -184/4
p = -46
The awnser is 96 because you would chose the one bigger or you wouldn't chose the one smaller so choose a medium number 96
Answer:
5/8 cm
Step-by-step explanation:
5/2*3/4=15/8
15/8*1/3=15/24=5/8
Answer:
14.85
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
A =1/2 ( 6.6)(4.5)
A = 14.85
