Answer:
The last expression is correct
Step-by-step explanation:
We have been given the following expression for simplification;
The bases of the two expressions are the same. They are both equal to 4. When multiplying numbers with the same base, we simply add their exponents. In this case our exponents are;
4 and -9
adding them we have;
4 + (-9) = -5
The simplified expression thus becomes;
Answer:
2
Step-by-step explanation:
Identify the coordinates as x1, y1 and x1, y2. Solve by using the formula of slope(gradient)
112 is correct, 56 times 2.
Answer:
The equation that represents the population after T years is
Step-by-step explanation:
Population in the year 2018 ( P )= 7,632,819,325
Rate of increase R = 1.09 %
The population after T years is given by the formula
-------- (1)
Where P = population in 2018
R = rate of increase
T = time period
Put the values of P & R in above equation we get
This is the equation that represents the population after T years.
$305.25 divided by $9.25 equals 33, so he worked 33 hours... hope this helped.
