Students are painting the backdrop for the school play the backdrop is 15 feet wide and 10 feet high every 16 inches on the scal
laiz [17]
Actual:
15 ft wide and 10 ft high.

Area = 15ft * 10ft
Area = 150ft²

Scale drawing.
Every 16 inches represent 5 feet in the back drop.

15ft ÷ 5ft = 3 * 16 inches = 48 inches
10ft ÷ 5ft = 2 * 16 inches = 32 inches

Area = 48 in * 32 in
Area = 1536 in²

Area of the scale drawing is 1,536 square inch.

Solve the quadratic equation for x. What is the product when the roots are multiplied? (x + 2)2 = 1 A) −3 B) −6 C) −9 D) 3
ehidna [41]

Answer:

D

Step-by-step explanation:

To solve the quadratic equation, use the inverse operation to squaring. This will undo the exponent and allows x to be isolated. The inverse operation is the square root. This is called the square root property of equality.

(x + 2)² = 1

√(x+2)² = √1

(x+2) = ±1

x = 1 -2     and   x = -1 - 2

x = -1        and   x = -3

The product of the roots -1 and -3 is -1*-3 = 3

A line segment has (x1, y1) as one endpoint and (xm, ym) as its midpoint. Find the other endpoint (x2, y2) of the line segment i
Levart [38]

Answer: (a) (x_{2},y_{2}) = (3,2)

              (b)  (x_{2},y_{2}) = (19,-7)

Step-by-step explanation: Midpoint of a segment is halfway between 2 endpoints. It is calculated using the formulas:

x_{m}=\frac{x_{1}+x_{2}}{2}

y_{m}=\frac{y_{1}+y_{2}}{2}

Isolating x_{2}:

2x_{m}=x_{1}+x_{2}

x_{2}=2x_{m}-x_{1}

And y_{2}:

2y_{m}=y_{1}+y_{2}

y_{2}=2y_{m}-y_{1}

(a) Replacing values and calculating x_{2}:

x_{2}=(2*2)-1

x_{2}=3

Calculating y_{2}:

y_{2}=[2*(-1)]-(-4)

y_{2}=2

(x_{2},y_{2})=(3,2)

(b) x_{2}=(2*5)-(-9)

x_{2}=19

y_{2}=(2*6)-19

y_{2} = -7

(x_{2},y_{2})=(19,-7)
