Answer:
16
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
y(y² + 4y + 16) - 4x(y² + 4y + 16) ← distribute both parenthesis
= y³ + 4y² + 16y - 4xy² - 16xy - 64x
Compare - axy to - 16xy ⇒ a = 16
You are given a set of data regarding the truck with the <span>distance y, in miles, traveled by a truck in x hours:
Time (x) (hours) 1 2 3 4
Distance (y) (miles) 50 100 150 200
I used excel to plot this data and get an equation and the value of r to anwer the following questions.
Part A: The most likely value of the correlation coefficient of the data in the graph is 1, meaning that the distance travelled by the truck and the time it takes to travel is directly related or directly proportional.
Part B: From the graph, i got an equation y = 50x with a slope of 50.
Part C: The table presented above is a correlation because both variables are directly related and forms a straight line rising to the right.</span>
Answer:
72
Step-by-step explanation:
Find the Rule :
2-1=1
3-1.5=1.5= constant
Verification :
1x1.5=1.5
2x1.5=3
9x1.5=13.5
48x1.5=72
What is the rule for input-output table?
An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is: multiply each input number (x-value) by 1.5 to find each output number (y-value)
A negative exponent means to move the decimal point to the left the number of the exponent.
10^-1 you would move the decimal 1 place to the left.
5.401 x 10^-1 = 0.5401
I believe the answer would be 6.96 cm
