5(x - 2) + 3x = 5x - 10 + 3x = 8x - 10
Answer:
989.61
Step-by-step explanation:
Answer: 22j
Explanation:
1) From the graph you can calculate the vector v as folllows:
Translation of the extreme (-5,0) to the origin (0,0) implies add 5 units to - 5.
Then, add 5 units to the x-coordinate of the other extreme: 7 + 5 = 12; and keep the y-coordinate, which is 2.
Therefore, the coordinates of the vector v are (12,2)
2) Now you can find the vector v - 4u applying the operations to the coordinates of the two vectors:
v - 4u = (12,2) - 4(3, -5) = (12,2) - (12,-20) = (12 - 12, 2 + 20) = (0,22)
3) Changing the notation in terms to i, j; that is 0i + 22j = 22j
Answer:
The correct option is 3. The function is a stretch of an exponential decay function.
Step-by-step explanation:
The general form of an exponential function is
where, a is the initial value and b is the growth factor.
If b<1, then it represents a decay function and if b>1, then it represents a growth function.
Let k be a stretch and compression factor.
If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.
In third function
Therefore the function is a stretch of an exponential decay function.
Answer:
(E) 1/5
Step-by-step explanation:
The probability that Harry will be chosen to be the secretary but not the president is 
The probability that Harry will be chosen to be the treasurer but not the president or secretary is 
Thus, the probability that Harry will be either the member chosen to be the secretary or the member chosen to be the treasurer is
