Answer:
Step-by-step explanation:
1. (sq root of) a^2 if a>0 => √(a^2) = ±a
2. (sq root of) 36x^2 if a>0 => ±6x
Answer:
(a) Find out the a rule to describe the function.
To prove
Let us assume that the days be represted by d .
Let us assume that the height of plant be represted by y.
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
Than the function becomes
y = 12 + 0.5 × d
y = 12 + 0.5d
(b) Find out after how many days will the zucchini plant be 0.195 meter tall .
To prove
Let us assume that the days be represted by d .
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
As
1meter = 100cm
0.195 meter convert into centimeter.
= 19.5cm
Than the equation becomes
12 + 0.5d = 19.5
0.5d = -12 + 19.5
0.5d = 7.5
d = 7.5/10
d = 15 days
Therefore 15 days will the zucchini plant be 0.195 meter tall .
Answer:
D. 80 ft
substitute known values into the equation for area
Answer:
HW → CT
∠ X → ∠ S
∠ D → ∠ L
DW → LT
Step-by-step explanation:
The quadrilateral DXHW is similar to quadrilateral LSCT.
So, side HW of the quadrilateral DXHW matches with the CT side of the quadrilateral LSCT.
And angle ∠ X of the quadrilateral DXHW matches with the angle ∠ S of the quadrilateral LSCT.
Again, angle ∠ D of the quadrilateral DXHW matches with the angle ∠ L of the quadrilateral LSCT.
Finally, side DW of the quadrilateral DXHW matches with the LT side of the quadrilateral LSCT. (Answer)
