Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
Answer: (x+8)(x+2) = x^2 + 10x + 16
Answer:
25.1cm
Step-by-step explanation:
since circumference =
d and d=2r
c=(2*4)
c=8
c=25.132741229
c=25.1cm
Answer:
240
Step-by-step explanation:
First start with the inner most bracket
20 - 6 = 14
Then solve the next bracket
14 + 1 = 15
Then the next
15 x 8 = 120
Then divide by a half (times by 2)
120 / 0.5 = 240
(y² - 3)(y⁴ - 6y² + 9)
y²(y⁴ - 6y² + 9) - 3(y⁴ - 6y² + 9)
y².y⁴ - y².6y² + y².9 -3.y⁴ - 3.(-6y²) -3.( 9)
y⁶ - 6y⁴ + 9y² - 3y⁴ + 18y² -27
y⁶ - 6y⁴- 3y⁴ + 9y² + 18y² - 27
y⁶ - 9y⁴ + 27y² - 27
I hope this helps.
