Answer:
Step-by-step explanation:
A column vector is shown in the form where x is how many spaces to move in the positive x direction y is how many spaces move in the positive y direction.
The vector b moves 4 spaces to the right (which is in the positive direction of x) and doesn't move up or down in the y direction which is 0, so the column vector is
Answer:
y(x)=2866.59*(1.06)^x
Step-by-step explanation:
Let the exponential equation be y=a*b^x. Using y(7) and y(4) we can find the value of b, y(7)/y(4)=b^3=4300/3619, b=1.06. Next, y(4)=a*(1.06)^4=3619, a=2866.59. The equation is y(x)=2866.59*(1.06)^x

Answer:
Number of jars filled is 3 (approximately 4).
Step-by-step explanation:
Initial amount of salt = 1/2 cup.
Amount of salt left = 1/9 cup.
Amount of salt used = 1/2 - 1/9
=
= 7/18
The size of each jar = 1/10 cup.
Amount of salt used = size of the each jar x number of jars filled
7/18 = 1/10 x number of jars filled
number of jars filled = 7/18 ÷ 1/10
= 7/18 x 10/1
= 70/18
= 3
= 3.9
The number of jars filled is approximately 4.
