Standard form of an exponential function is y=ab^x
when x=0, y=3, 3=ab^0, so you can figure out that a=3
when x=-1, y=6, 6=3b^(-1), b^(-1)=2, b=1/2
so the equation is y=3(1/2)^x
Answer:
The diameter is 18 yards
Step-by-step explanation:
Diameter is 2 radius's in our case 9 plus 9 equals 18. But hey don't forget the units so it is 18 yards.
Answer:
(b) 68
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, and . The distance between them is given by:
Diagonal:
Diagonals are a line between opposite points in a square.
In this question, it is between A(0,3) and B(5,0), and between (0,0) and (5,3). Both these diagonals have the same measure, and are the distance between these points. So
Then sum of the squares of its both diagonals is units
Both diagonals measure . Sum of squares is:
The correct answer is given by option b.
Plug in 0 for x to find the y-intercept
0 + 4y = 36
4y = 36
y = 9
y-intercept (0, 9)
Plug in 0 for y to find the x-intercept
x + 4(0) = 36
x = 36
x-intercept (36, 0)
