Laura estimated the total cost of attending a private four-year university using the information in the table. category estimated cost – 1 year tuition $29,500 room and board $9,600 books $2,125 lab and facilities fees $850 laura received a grant that will pay for 30% of her annual estimated tuition and a scholarship that will pay for her books. what is the minimum laura should expect to contribute to her college education for all four years?

1/6

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
