Answer:
see explanation
Step-by-step explanation:
To find the zeros let h(t) = 0, that is
t² + 4t + 3 = 0 ← in standard form
(t + 3)(t + 1) = 0 ← in factored form
Equate each factor to zero and solve for t
t + 3 = 0 ⇒ t = - 3 ← smaller t
t + 1 = 0 ⇒ t = - 1 ← larger t
(2)
given a parabola in standard form : ax² + bx + c ( a ≠ 0)
Then the x- coordinate of the vertex is
= - 
h(t) = t² + 4t + 3 ← is in standard form
with a = 1 and b = 4, thus
= - 
= - 2
Substitute t = - 2 into h(t) for y- coordinate
h(- 2) = (- 2)² + 4(- 2) + 3 = 4 - 8 + 3 = - 1
Vertex = (- 2, - 1 )

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
When you shift down by 5 units, you are basically -5ing to every value in the bottom part of the chart.
For the bottom of the chart, I get:
0,2,8,14
While the top is
1,2,3,4 as nothing changes here.
The only chart like this is A.
Answer:
8x +4y
Step-by-step explanation:
6x + 3y + 2x + y
1) add similar variables together.
2) 6x + 2x = 8x
3y + (1)y = 4y.
3) y by itself basically means 1y, since in front of every variable theres an invisible 1.
Answer:
The infant should be given 700 mg of Claforan every 8 hours.
Step-by-step explanation:
This question involves proportional measures, and asks how many mg of Claforan the infant should be given every 8 hours.
For each kg, the infant should be given 50 mg of Clarofan. The infant weighs 14 kg, so he should be given 14*50 = 700 mg of Claforan every 8 hours.
