to make a perpendicular function from another we must take its slope and make two transformations
the slope of y=1/3x is 1/3
the transformations:
1.
reverse the number
2.
and change the sign
ok we have the slope now need the general equation of the line
where m is the slope , b a cut point and (x,y) a point
so, we have the slope=-3 , and the point (2,-3) we can replace to find b
now we can replace b and the slope to have the final equation
Answer:
A
Step-by-step explanation:
Note
One thing you should automatically notice is that x is larger, much larger than 20. x is the hypotenuse of a right triangle
Formula
Sin(18) = opposite side / hypotenuse
Givens
Sin(18) = 0.30902
opposite = 20
hypotenuse = x
Solution
sin(18) = 20 / x Multiply both sides by x
x sin(18) = 20*x /x
x sin(18) = 20 Divide by sin(18)
x sin(18) / sin18 = 20/sin(18)
x = 20 / 0.30902
answer: x = 64.72
Answer:
- 16
Step-by-step explanation:
The way this is given, you have to find the second term before you can fine the third.
a2 = d(n - 1) * (-2)^2
a2 = 2 * (-2)^2
a2 = 2 * 4
a2 = 8
a3 = d(3 - 1) * (-2)^3
a3 = 2 * (-2)^3
a3 = 2 * - 8
a3 = - 16
