Step-by-step explanation:
area of rectangle = l × h
= 9 × y
= 72
9 × y = 72
y = 72÷9
y = 8cm
area of circle = 50.27cm²
total area of the logo = 2(50.27) + 72
= 100.54 + 72
= 172.54cm²
Answer: I think the answer would be (2, -1)
Answer:
b) trapezoids
Step-by-step explanation:
a trapezoid has atleast one pair of opposite parallel sides
Answer:
= 2n - 3
Step-by-step explanation:
Note the difference in consecutive terms is constant, that is
1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 2
This indicates that the terms are an arithmetic sequence with
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 1 and d = 2, thus
= - 1 + 2(n - 1) = - 1 + 2n - 2 = 2n - 3
