The age of the giraffe when he is 15 feet tall be 1 year 1 month and 16 days.
<h3>What is fraction?</h3>
A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Giraffe height = 6 feet
Height grew in 7 months= 1.75 feet
Giraffe's height in 7 month = 7.75 feet
Giraffe's height, 1 feet= 
month
= 0.9032 months
Giraffe's height, 15 feet= 0.9032 x 15 month
= 13.548 month
= 13 months 16 days approx.
= 1 year 1 month 16 days
Hence, the age of giraffe will be 1 year, 1 month and 16 days

Answer:
B) -1
Step-by-step explanation:
This is the equation of a parabola which can be expressed as
y = a(x-h)² + k (1)
where (h, k) are the coordinates of the vertex which is the minimum or maximum of the graph. Strict definition is where the parabola intersects the line of symmetry ie the line which cuts a shape into half
Parabolas are symmetric around the line of symmetry
Here we see the vertex is at x = 0, y = 9 (0,9) so h=0 and k = 9
Substituting equation (1) we get
y = a(x -0)² + 9 = ax² + 9
To find a all we have to do is choose any point on the parabola, plug its x and y values into the parabola equation above
A convenient point is where the parabola intersects the positive x axis. Here x = 3 and y = 0
Plugging these values we get
0 = a(3)² + 9
a = -9/9 = -1
Answer:
x=11.1
Step-by-step explanation:
6x-4x-20=2.2
2x-20=2.2
2x=22.2
x=11.1
