Answer:
I will provide the steps below.
Step-by-step explanation:
First, You will need to plug in the 8.
2(8)-(1/-3)=-5
Multiply
16-(-1/3)=-5
If we have two negitive it turns into possitive.
16+1/3=-5
16+1/3=-5
This statement is not true becuase if y=8 the equation will be (16+1/3)=5
*Make sure your giving me the right eqution otherwise this statment is false.*
Answer:
30 square feet
Step-by-step explanation:
To find the area of a right triangle you use the formula (leg x leg)/2. So to find the area, first you need to have both of the leg measurements, so you need to use Pythagorean's theorem. After using the theorem, you get 12 feet for the measurement of the other leg, so you multiply 12 by 5. 12 times 5 is 60, so you divide that by 2 (as seen in the original formula) and get your answer of 30.
Answer:
2010.
Step-by-step explanation:
We have been given an exponential growth formula 
, which represents number of passengers traveling by airplane since 1990.
To find the year in which 900 million passengers will travel by airline, we will equate the given formula by 900 and solve for t as:
Take natural log of both sides:
Using property 
, we will get:
This means that in the 20th year since 1990, 900 million passengers would travel by airline.
Therefore, 900 million passengers would travel by airline in 2010.
