Answer:
y = -5x + 19
Step-by-step explanation:
Note that the equation of any line parallel to y= -5x+7 has the same form as y= -5x+7, but a different constant. Knowing that this new line passes thru (2,9), we determine the value of this constant as follows: 9 = -5(2) + C, or 9 = -10 + C. Then C = 19, and the equation of this new line is
y = -5x + 19
Answer:
Step-by-step explanation:
We use trig to answer these questions:
sin x = opposite side of a triangle / hypotenuse
cos x = adjacent side / hypotenuse
Construct a right triangle with hypotenuse 4 m and lower angle 68 degrees.
The height of the top of the ladder is then defined by:
sin 68 degrees = height / 4 m, which yields (4 m)(sin 68) = height =
3.71 m
and the distance of the bottom of the ladder from the wall as follows:
cos 68 degrees = horizontal distance / hypotenuse =
1.50 m
Answer:
4
Step-by-step explanation:
f(x) = 4 ^ ( x-2)
Let x=3
f(3) = 4 ^ ( 3-2)
= 4 ^ 1
= 4
