Answer:
43,200 serial numbers can be generated
Step-by-step explanation:
The ordering for the letters and the digits are important. For example, 012 constitutes a different serial number than 210. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
How many serial numbers can be generated
3 letters, from the first five of the alphabet
3 digits, from a set of 10
So
43,200 serial numbers can be generated
Answer: 152 degrees.
Step-by-step explanation: Since angle 1 and angle 5 are alternate exterior angles, they are congruent. Thus, angle 5 is also equal to 152 degrees.
Answer:
A. y-axis only
Step-by-step explanation:
We have the graph of as given below.
It can be seen that passes through the points (0,0), (4,0) and (6,0).
Also, the graph is plotted in the 1st and 2nd quadrant symmetrically along the y-axis.
Hence, the axis of symmetry of is the y-axis only.
Answer:
5y-4x= -7 :
Slope = 
= 0.800
<em>x </em>- <em>intercept = </em>
= 1.75000
<em>y - intercept = - </em>
= -1.40000 <------both of these numbers a negative
----------------------------------------------
2y+4y = 14 :
<em>y = </em>
= 2.333
----------------------------------------------
