Step-by-step explanation:
x = 3/2 + y/2
Answer:
The area is 64ft ^2.
Step-by-step explanation:
I believe this is an isosceles triangle and if so our base will be 16ft and our height will be 8ft, knowing this we can solve for the area.
Use the form A=bh/2
Now plug it in...
A=16x8/2
A=128/2
A=64ft ^2
Hope this helps :)
Answer:
As the height increases, the temperature decreases.
It is decreasing 5°C per kilometer.
At the height 8 km the temperature is 0°.
Answer:
$471.07
Step-by-step explanation:
$123.54 + $98.66
=$222.2
$693.27 - 222.2
=471.07
Answer:
A
Step-by-step explanation:
you can find the vertex of each equation and then compare to the graph
x = -b/2a
A) x = -(-9)/2(1); x = 9/2 or x = 4 1/2
plug 4 1/2 into equation as 'x' to find 'y'
y = (9/2)² - 9(9/2) + 20
y = 81/4 - 81/2 + 20
y = 81/4 - 162/4 + 80/4
y = -81/4 + 80/4
y = -1/4
the only option with a vertex at (9/2, -1/4) is A
