Triangle PQR is transformed to similar triangle P′Q′R′:
Arturiano [62]
Answer: The scale factor of the dilation is 1/3.

In a dilation, we are multiplying all the points by a constant to get a set of new points. The shapes will be similar.

In this case, we are moving from Point P at (-6, 6) to Point P' at (-2, 3).

So how does the point change. Let's write and solve the following equations.

-6k = -2   or 6k = 2
k = 1/3      k = 1/3

In both cases, the point was multiplied by 1/3. This is true of all the points.

Find the value of p if the following pair of equation may have one root common:
Diano4ka-milaya [45]

The value of p if the pair of equations may have one root common is 1.

<h3>What are the roots of the equation?</h3>

Let the equation be ax² + bx + c = 0.

Then the roots of the equation will be

\rm x = \dfrac{-b \pm \sqrt{b^2 - 4 a c }}{2a}

The equations are given below.

2x² + px - 1 = 0 and 3x² - 2x - 5 = 0

The roots of the equation 3x² - 2x - 5 = 0 will be

3x² - 5x + 3x - 5 = 0

(3x - 5)(x + 1) = 0

x = -1, 5/3

At x = -1, the value of p will be

2(-1)² + p(-1) - 1 = 0

2 - p - 1 = 0

p = 1

The value of p if the pair of equations may have one root common is 1.

More about the roots of the equation link is given below.

What is the approximate area of the figure?
Valentin [98]

Answer:

Answer D (2206.5 ft^2) is closest to the calculated answer 2206.85 ft^2.

Step-by-step explanation:

We can break up this figure into a 30 ft by 50 ft rectangle and a circle of diameter 30 ft.

The area of the rectangular part is A1 = (30 ft)(50 ft) = 1500 ft^2.

The area of the circular part is A2 = π(15 ft)^2 = 706.9 ft^2

Thus, the total area is approx A1 + A2, or 2206.86 ft^2 (Answer D)
