QUESTION 1 1.1.
A quadratic pattern has a second term equal to 1, a third term equal to -6 and a fifth
term equal to - 14.
1.1.1. Calculate the second difference of this quadratic pattern.
(5)
1.1.2. Hence, or otherwise, calculate the first term of the pattern.
(2)

answer:

c 60% on edg

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
