Answer:
- C) (x, y) ⇒ (-x, y)
- D) (x, y) ⇒ (x, y+4)
Step-by-step explanation:
ΔDEF is a reflection and translation of ΔABC.
You know it is a reflection because the corresponding vertices have opposite orientations: CCW vs. CW. You know it is a horizontal reflection because the line EF corresponding to vertical line BC is still vertical.
You know a vertical translation is involved because corresponding vertices are all offset vertically from each other by the same amount (4 units).
Answer:
The rider is 15.91 seconds 50 ft above the ground after reaching the low point
Step-by-step explanation:
We can evaluate the angle α
using trigonometry applied to the orange small triangle with height 50-30 = 20 ft and hypotenuse equal to the radius r = 25ft
Now
So 50
ft of height corresponds to the total angle:
= 2.498 radians
Now the angular velocity
To describe 2.498 rad it will take:
t = 15.91
s
Answer:
Step-by-step explanation:
The answer is
72% of his earnings is $18x 72 / 100 = $12.96
Tyrone works 40 hours per week
in one month
he works 40*4=160 hours
so 1 hour is for $12.96 net
160 hours for x=?
x=$2073.6
his total monthly cash inflow is $2073.6 - $1,800=$273.6
Answer:
Step-by-step explanation:
This basically the general formula of Slope point form for the linear equation.
Defining the slope of the line and a point on the line (not actually the y-intercept)
(x1,y1) = Point on the line
m = slope on the line
