Answer:
A
Step-by-step explanation:
From the diagram:
- P(-4,6)→P'(4,6);
- Q(-7,4)→Q'(7,4);
- R(-6,1)→R'(6,1);
- S(-2,1)→S'(2,1);
- T(-1,4)→T'(1,4).
The general rule of this reflection is
(x,y)→(-x,y)
and this is reflection across the y-axis. The y-axis has the equation x=0.
Answer:
19 in
Step-by-step explanation:
Since, one revolution is equal to the circumference of the wheel.
C= πd
->The wheel of a compact car has a 25-in. diameter. The circumference of the compact car will be:
C= π x 25
C= 25 π in
->The wheel of a pickup truck has a 31-in. diameter. The circumference of the pickup truck will be:
C = π x 31
C= 31π in
Next, is to determine differences in distance 'd' traveled by subtraction the circumferences
d= 31π - 25π
d=6π (since π= 3.14)
d= 6 x 3.14
d=19 in
Therefore, the pickup truck wheel traveled 19in farther in one revolution than the compact car wheel
Standard From =
F(x) = 5x2 - 5
