8) The price of a gallon of gasoline is increasing by 1¢ per week. If the price is $3.08 per gallon today, what will it be in ten weeks?
A) Linear; $3.18
B) Exponential; $3.11
C) Exponential; $3.40
D) Linear; $3.17

i belive those are the ones that are under 90 degreese.

70.30

step-by-step explanation:

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
