Introduces reflections in the x- and y-axes. ... To see how this works, take a look at the graph of h(x) = x2 + 2x – 3. ... The previous reflection was a reflection in the x-axis. ... f (x – b) shifts the function b units to the right.
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° =
=
=
( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA =
≈ 3.1 ft ( to the nearest tenth )
Answer:
Yes
Step-by-step explanation:
The z-score corresponding to a number or score can be calculated using:

Where x stands for the individual scores, and
