Answer:

y = x² - 2x - 3

Step-by-step explanation:

y + 4 = C(x - 1)²

To determine C, use x = 4, y = 5

5 + 4 = C(4 - 1)²

9 = 9C, C = 1

y + 4 = (x - 1)² = x² - 2x + 1

y = x² - 2x - 3

Answer:

Step-by-step explanation:

We cannot take the square root of a negative number without using complex numbers. Because of this, both 5x and x+3 must be non-negative in order for the product to be defined.

5x ≥ 0 implies that x ≥ 0
x + 3 ≥ 0 implies that x ≥ -3

Both of these are satisfied if and only if x ≥ 0 (note that if x ≥ 0, then x is automatically greater than or equal to -3). Therefore, the correct answer is x ≥ 0.

model aeroplane is made to a scale of 1 by two of the size of the real plane the area of the wings of the real plane are 40 m sq

4vir4ik [10]

The area of the wings of the model is 100000 square centimeters

<h3>How to determine the model area of the wings?</h3>

The given parameters are:

Scale factor, k = 1/2

Actual area of wings, A = 40 square meters

The model area is calculated as

Model area = Actual area * k^2

This gives

Model area = 40 * (1/2)^2

Evaluate

Model area = 10 square meters

Convert square meters to square centimeters

Model area = 10 * 10000 square centimeters

Evaluate

Model area = 100000 square centimeters

Hence, the area of the wings of the model is 100000 square centimeters
