Answer:
sqrt(24)
Step-by-step explanation:
The square root of 24 is between 4 and 5 since we know that 4 square is 16 and 5 squared is 25. 16 < 24 < 25.
Cheers.
Divide 110 by 5 to get 22 or choice A.
You do this because at the end of the day he has 5 times more so we do the inverse to get the beginning or divide by 5.
Answer: For number 1, the lines intersect, and for number 2, the lines are perpendicular.
Step-by-step explanation:
Perpendicular lines are lines that intersect to form a right angle, as shown for number 2, and intersecting lines are lines that intersect, creating obtuse and/or acute angles.
Answer:
35 students brought their lunch to school on Thursday
Step-by-step explanation:
700 students
Convert 5% to a decimal
5% = 0.05
Then multiply
700 * 0.05 = 35
It will take 15 years for the population to quadruple
Step-by-step explanation:
The formula for continuously compounding rate is , where
- A is the future amount
- P is the initial amount
- r is the interest as a decimal
- t is the time in years
Assume that the initial population is P
∵ The initial population = P
∵ The growth rate = 9% ⇒ compounded continuously
∴ r = = 0.09
∵ The population will quadruple in t years
∴ A = 4P
- Substitute these values in the formula
∵
∴
- Divide both sides by P
∴
- Insert ㏑ to both sides
∴ ㏑(4) = ㏑( )
∵ ㏑( ) = n
∴ ㏑ (4) = 0.09 t
- Divide both sides by 0.09
∴ t = 15.4
∴ t = 15 years to the nearest whole number
It will take 15 years for the population to quadruple
