Answer
Find out the value of x.
To prove
By using the trignometric identity
As given in the diagram.
Perpendicular = x
Hypotenuse = 6
Put in the above identity
Put in the above
x = 4.6 cm (Approx)
Therefore Option (c) is correct .
The independent variable is the number of sweatshirts sold so it is answer A.
(Money raised is the dependent variable because it depends on the number of sweatshirts sold.)
Answer:
15
Step-by-step explanation:
Rate of change or slope or gradient of a line passes two points (x1, y1) and (x2, y2) could be calculated by:
(y2 - y1)/(x2 - x1)
=> Rate of change of the line passing (1,15) and (3,45):
(45 - 15)/(3 - 1) = 30/2 = 15
We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.
