Answer:
y = 20*4^x
Step-by-step explanation:
to find the value of the constants a and b, we just need to use the points given in the equation and solve the system of equations:
point (0,20): x = 0 and y = 20:
20 = a*b^0 = a*1 = a
a = 20
point (2,320): x = 2 and y = 320
320 = 20 * b^2
b^2 = 16
|b| = 4
b = 4 or b = -4
So we have two exponencial equations that pass through these points:
y = 20*4^x and y = 20*(-4)^x
As the questions asks for just one equation, we can answer y = 20*4^x
Answer:
it is half the area of a square of side length 8
Step-by-step explanation:
area of a square = l × b
= 8 × 8
= 64 cm^2
area of a triangle = b × h ÷ 2
= 8 × 8 ÷ 2
= 64 ÷ 2
= 32 cm^2
