Answer:
a = 9, b = 3
Step-by-step explanation:
The exponential function is
y = a
Find a and b by using the points it passes through
Using (0, 9 ) then
9 = a (
= 1 )
a = 9
y = 9
Using (3, 243 ) then
243 = 9b³ ( divide both sides by 9 )
27 = b³ ( take the cube root of both sides )
b = = 3
y = 9 ← exponential equation
Answer:
$5.60
Step-by-step explanation:
Check the picture below, the assumption being that the 6ft line is perpendicular to the 18ft line and thus making a right-triangle.
now, if we just get the whole area of the containing parallelogram and then <u>get the area of the triangle and subtract it from that of the parallelogram's,</u> what's leftover is the area we didn't subtract, the shadead area.
