Answer:
[(x + 3) (x + 7)] / (3x + 21)
= [(x + 3) (x + 7)] / [3 (x + 7)]
= (x + 3) / 3
The denominator can't be equal to 0 therefore:
3 (x + 7) ≠ 0 ⇔ x + 7 ≠ 0 ⇔ x ≠ -7
The range of x-values extrapolation occurs in between x < 0 and x > 6
We have given that,
On a graph, points are at (0, 15), (1, 17), (3, 18), (4, 20) and (6, 22).
<h3>
What is the range?</h3>
The Range is the difference between the lowest and highest values.
Therefore we can conclude that the,
range of x-values extrapolation occurs in between x < 0 and x > 6.

Let X(t)=the position function with respect to time, t.
We're given:
X(0)=12 (from graph)
v(0)=0
X(2.5)=7
There is enough information to construct X(t).
In general,
X(t)=kt^2+v(0)(t)+x0
where initial velocity=v(0)=velocity at time 0 = 0 (given)
x0=initial position at time 0 = 12 (from graph)
Substituting values, the position equation is
X(t)=kt^2+12
Substituting given value X(2.5)=7 => 7=k(2.5^2) + 12
Solve for k to get k=(12-7)/6.25 = -4/5
The position equation now becomes
X(t)=-4t^2/5+12
For t=25,
X(25)=-4(25^2)/5+12=-500+12 = 488 m
h is the plants hight and y is the plants age
A plants hight is 1.6 times it’s age
Equation: h = 1.6 y
Answer
h = 1.6 y
Answer:
- The perimeter of the whole square is <u>19.79898987</u> (to be exact).
- The area of the whole square is <u>24.5</u>
(Use Sine and Cosine to find the side lengths.)
