Answer:
So f(x) is y
y = |x| -4
Put in some numbers for x and see which graph matches the y output.
The first graph.
Answer:
400 ft
Step-by-step explanation:
h(t)= -16t^2 + 160t
The vertex is found at
h = -b/2a where b is the coefficient of t and a is the coefficient of t^2
= -160/(2*-16)
-160/-32
5
The time where the maximum occurs is at t=5
To find the maximum substitute into the function
h(5) = -16 (5)^2 +160*5
= -16*25 +800
=-400+800
= 400
The maximum height is 400 ft
Answer:
4/24
Step-by-step explanation:
We have an arithmetic progression:
An arithmetic progression is a sequence of numbers such that the diference between the consecutive terms is constant.
Explicit formula:
an=a₁+(n-1)*d
a₁ is the first term
d is de common diference
n is the numbers of terms
In this case:
a₁=-9
d=an-an-1=a₂-a₁=-16-(-9)=-16+9=-7
an=-9+(n-1)*(-7)
an=-9-7n+7
an=-7n+-2
a₁=-7*1-2=-9
a₂=-7*2-2=-14-2=-16
a₃=-7*3-2=-21-2=-23
a₄=-7*4-2=-28-2=-30
a₅=-7*5-2=-35-2=-37
a₆=-7*6-2=-42-2=-44
Answer:
7
Step-by-step explanation:
From O(7,4), when you move a point 4 units left, abscissa decreases by 4,i.e it becomes 3 and when you move a point 3 units up, ordinate increases by 3,i.e it becomes 7.
