Answer:
Step-by-step explanation:
olve the line equation for y
:
y = -ax/2 +5
:
therefore, the y-axis intercept is 5
:
area of triangle = (1/2) * base * height
:
(1/2) * base * 5 = 10
:
base = 4 which is the x-axis intercept
:
-a(4)/2 +5 = 0
:
-2a = -5
:
a = 5/2
:
Answer:
A
Step-by-step explanation:
The median AB bisects DC at right angles ,hence BD = 4
Using Pythagoras' identity on the right triangle ABD
The square on the hypotenuse AD is equal to the sum of the squares on the other 2 sides, that is
AB² + BD² = AD², that is
AB² + 4² = 5²
AB² + 16 = 25 ( subtract 16 from both sides )
AB² = 9 ( take the square root of both sides )
AB = = 3 feet → A
