The answer is A

Reasoning;

a1 = first term;
an= an-1 + d
In a sequence you add the first term (a1) with the second term in a repeating linear equation. In this one you need to add 4 to each term so, the equation is;

a1 = 2
an = an -1 + 4

creating:
2 6 10 14 18 22 26...

Viefleur [7K]

Answer:

-15

Step-by-step explanation:

The negative is outside of the absolute value signs/lines. The absolute value is how far the number is from 0. So, it doesn't matter whether or not there is a negative sign inside of the absolute value lines it will always be positive. But, if it's outside of it, then it will be negative.

a leaf hangs from a branch 12 feet in the air. it falls to the ground at a rate of 0.25 feet per second. which graph could repre

Kipish [7]

For this case we have an equation of the form:
$h (t) = (1/2) * (a) * (t ^ 2) + v0 * t + h0
$
Where,
h0: initial height
v0: initial speed
a: acceleration
Substituting values we have:
$h (t) = (1/2) * (- 32) * (t ^ 2) + 0.25 * t + 12
$
Rewriting we have:
$h (t) = -16t ^ 2 + 0.25 * t + 12
$
Note: see attached image
Answer:
$h (t) = -16t ^ 2 + 0.25 * t + 12$
