Answer:
A. Yes, (0,0) satisfies both inequalities.
Step-by-step explanation:
The given inequalities are;
and
For (0,0) to be a solution to the given system of inequalities then it must satisfy both inequalities.
We substitute (0,0) into the system of inequalities to obtain;
This implies that;
; True
and
This implies that;
: True
Since (0,0) satisfies the two systems, it is a solution.
The correct choice is A.
Answer: 9.9 years.
Step-by-step explanation:
If interest is compounded continuously, then formula to compute final amount A = , where P =initial amount, r= rate of interest , t=time.
Given: P= $61,000, r= 1.9% =0.019 , A = $ 73600
Substitute all values in formula
Taking natural log on both sides
Hence, the required time = 9.9 years.
Answer:
Sandwich sells for $4.76 .
Step-by-step explanation:
As given
It costs $2.80 to make a sandwich at the local deli shop.
To make a profit, the deli sells it at a price that is 170% of the cost.
170% is written in the decimal form
= 1.7
Thus
Sandwich selling cost = 1.7 × Cost of making
Put all the values in the above
Sandwich selling cost = 1.7 × $ 2.80
= $4.76
Therefore the Sandwich sells for $4.76 .
