Answer:
emissions = 40·0.65^t
Step-by-step explanation:
The decay factor in an exponential equation is 1+(decay rate), so the equation can be written ...
amount = (initial amount)×(decay factor)^t
where the decay factor applies to 1 unit of time t. Filling in the given values, we find ...
decay factor = 1 +(-35%) = 0.65 . . . . for 1 year
emissions = 40×0.65^t . . . . . million tons, for t in years
Answer:
20in²
Step-by-step explanation:
The area of a triangle is calculated using the formula A = bh/2
"A" means area.
"b" is for the base.
"h" is for the height.
It does not matter which is the base and which is the height, as long as they are perpendicular (at 90°) to each other.
5in can be the height.
8in can be the base.
Put the base and height measurements into the formula.
A = bh/2
A = (8in)(5in)/2 Multiply the measurements and the units.
A = (40in²)/2 Divide by 2
A = 20in² Area of the triangle
When you multiply units, in X in becomes in².
"in" has the exponents 1. When you multiply two "in" with exponent 1, you add the exponents. 1 + 2 = 2.
in¹ X in¹ = in¹⁺¹ = in²
