The function below models the correlation between the number of hours a plant is kept in sunlight (x) and the height (y), in mm, to which it grows:y = 4 + 2x
What does the y-intercept of this function represent?
The original height of the plant was 4 mm.
The original height of the plant was 2 mm.
The height of the plant increases by 2 mm for every hour of sunlight it receives.
The height of the plant increases by 4 mm for every hour of sunlight it receives.

Answers

Answer 1
Answer: Remember that the y-intercept is obtained when the value of x is set to zero. This means that the y-intercept is the value of the height without sunlight yet. This also refers to the original height of the plant. This gives:

y = 4 + 2(0) = 4

So, the original height of the plant is 4 mm.

The formula also indicates that when sunlight is present, a height of 2mm is increased every hour of sunlight exposure.

What are the real or imaginary solutions of the polynomial equation? x^3 = 216

Answers

x^3 = 216
this means that
x = 216^1/3
x = 6 (real solution)

x = -3 -3^(3/2)i (imaginary solution)
x = -3 +3^(3/2)i (imaginary solution)


x³ = 216 
∛x³ = ∛216
x = 6

Answer:

Lesson 1 Unit 2: Roots and Radical Expressions

1 = a (no real root)

2 = c (-0.05)

3 = c (6lg^3l)

4 = d (5x^7y^8)

5 = a (3x^2/5y)

5/5 100%

Step-by-step explanation:


First we write down this expression:
\sqrt{36* g^(6) }
We notice that 36 is a square of 6 so we write:
\sqrt{ 6^(2)*g^6 }

Now, square root we imply on each of factors (g^6 and 6 ^2)
we get.
6*|g^3|
The reason for absolute value is because of variable g.

Answer is C.
