What letter stays the same when reflected over the x-axis

1 answer:

6 0

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:

Robert is inspecting a shipment of 22 inch pipes. The length of the pipes may vary by 1%. What is the range of allowable lengths

Slav-nsk [51]

Answer:

The allowable lengths of pipe is from 21.78 inch to 22.22 inch.

Step-by-step explanation:

The length of the each pipe in the shipment = 22 inch

The variation in the length of pipes = 1%

⇒The allowable length of pipe in the inspection = 22 inch ± 1%

Now, 1% of 22 = $\frac{1}{100} \times 22 = 0.22$

So, 22 inch + 1% = 22 inch + 0.22 = 22.22 inch

and 22 inch - 1% = 22 inch - 0.22 = 21.78 inch

⇒ 22 inch ± 1% = 22.22 inch and 21.78 inch

Hence, the allowable lengths of pipe is from 21.78 inch to 22.22 inch.

Use the graph below to answer the following question:

larisa [96]

ANSWER

B) -1

EXPLANATION

From the graph,

f(1)=3 and f(4)=0.

The average rate of change from x=1 to x=4 of this function is,

$= \frac{f(4) - f(1)}{4 - 1}$

Substitute the functional values

$= \frac{0 - 3}{3}$

Simplify

$= \frac{-3}{3} = -1$

The correct choice is .
