B. We know the area of a triangle is 12 cm2. We also know the height is 6 cm. Find the base of the triangle (hint: you can use the formula in parta) cm help please

The base of traingle is 4cm.

Step-by-step explanation:

Given that the area of triangle is A = 1/2×b×h where b represents base and h is height. So you have to substitute the values into the expressions and solve it :

9514 1404 393

Step-by-step explanation:

If the base of a positive exponential is greater than 1, the function is a growth function. If it is less than 1, the function decays.

Remember that a^-1 = 1/a, so a negative exponential can be transformed to a positive one.

1. y = 2(11/5)^-x = 2(5/11)^x . . . . 5/11 < 1, so decay

2. y = e^(-2x) = (1/e^2)^x . . . . 1/e^2 < 1, so decay

3. y = 1/4e^x . . . . e > 1, so growth

e ≈ 2.71828 . . . an irrational number
