Sergio [31]3 years ago
7 0

Step-by-step explanation:

perimeter=2(l+b)

18=2[(x+2)+x]

18=2(x+x+2)

18=2(2x+2)

18=4x+4

collecting like terms

18+4=4x

22=4x

Circle P has center P(2,0) and a radius 20. Circle Q has center Q(0,4) and radius 2. Describe the rule for translating center Q
fomenos
The circle the has a center P(2,0) is bigger than compared to the circle with the center Q(0,4) because the former has a radius 20, while the latter has a radius of only 2. You can view the graph here: 
https://www.desmos.com/calculator/od1pwqylou

(a) Describe the rule for translating center Q onto center P. By moving the center of circle Q overlapping the center of circle P, then we need to move it two units left and 4 units up.

(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P. In getting the scale factor, we need to compare the radius
= 2/10
= 1/10
So, the scale factor is 1/10

(c) Are circles P and Q similar? Explain your answer.
Yes, by applying a dilation value, circle Q can be transformed to circle P, vice versa.

vitfil [10]

Answer:

Area of trapezium = 16.5 cm^2

Step-by-step explanation:

Given:

a = 5 cm

b = 6 cm

h = 3 cm

To Find:

Area of trapezium = ?

Solution:

Area of trapezium = h(a + b)/2

Area of trapezium = 3(5 + 6)/2

Area of trapezium = 3 x 11/2

Area of trapezium = 33/2

Therefore, Area of trapezium = 16.5 cm^2
