f(x) = x^2

1st transpose: f(x) = x^2 +7

2nd dilate: f(x) = 9(x^2+7)

3rd reflect: f(x) = 9x^2 + 63

f(x) = x^2

shift f(x) up 7 units means adding 7 to f(x)

so now f(x) = x^2 +7

vertically stretch the function by a factor of 9 means multiplying f(x) by 9

so now f(x) = 9(x^2+7)

f(x) = 9x^2 + 63

reflect across the y-axis means x becomes -x in f(x)

so now f(x) = 9(-x)^2 + 63

f(x) = 9x^2 + 63

In a survey of 2000 people, 50% of them visited the country A and 40% of them
denis23 [38]

Step-by-step explanation:

n (U)=2000

n (A)=50% of 2000

=(50÷100)×2000

= 1000

n( B) = 40%

= (40÷100)×2000

= 800

n(AuB)(compliment) = 15%

=(15÷100)×2000

=300

The perimeter of a rectangular piece of plastic is 30 millimeters. The area is 54 square millimeters. What are the dimensions of
Delvig [45]

Answer:

6 mm and 9 mm are the dimensions of the piece of plastic.

Step-by-step explanation:

Keep in mind the formulas for the area and perimeter of a rectangle:

A = lw

P = 2 (l + w)

List the factors of 54:

1, 2, 3, 6, 9, 18, 27, 54

POSSIBLE DIMENSIONS of the piece of plastic:

1 mm and 54 mm:

Area - 54 mm^2

Perimeter - 110 mm

2 mm and 27 mm

Area - 54 mm^2

Perimeter - 58 mm

3 mm and 18 mm

Area - 54 mm^2

Perimeter - 42 mm

6 mm and 9 mm

Area - 54 mm^2

Perimeter - 30 mm

The rectangular piece of plastic with the dimensions 6mm and 9 mm corresponds with the area and perimeter of the piece of plastic mentioned. So these are the correct dimensions.

Hope this helps!
