Answer:
2nd: 2
4th: -4
11th: -25
Step-by-step explanation:
When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:
A(2) = 5 + (2 - 1)(-3)
A(2) = 5 + (1)(-3)
A(2) = 5 - 3
A(2) = 2
To get the 4th term you substitute in 4:
A(4) = 5 + (4 - 1)(-3)
A(4) = 5 + (3)(-3)
A(4) = 5 - 9
A(4) = -4
And we do the same for the 11th term:
A(11) = 5 + (11 - 1)(-3)
A(11) = 5 + (10)(-3)
A(11) = 5 - 30
A(11) = -25
In mathematics, two variables areproportional if there is always aconstant ratio between them. Theconstant is called the coefficient ofproportionality or proportionality constant. ... x and y are directlyproportional if the ratio yx is constant.
In other words, the constant of proportionality is also the slope, **m**, rate of change, etc.
Answer:
- 4x³ - 33x² + 31x - 3
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x²(- 4x + 3) + 9x(- 4x + 3) - 1 (- 4x + 3) ← distribute all 3 parenthesis
= - 4x³ + 3x² - 36x² + 27x + 4x - 3 ← collect like terms
= - 4x³ - 33x² + 31x - 3
Answer:
-1
Step-by-step explanation:
If a straight line passes through the known points (x1, y1) and (x2, y2), the its slope is given by 
Now, in our case the straight line passes through the points (1.8, - 3.4) and (6.8, - 8.4).
Therefore, the slope of the required straight line will be
