The coordinate of the image after being reflected is R(3,4).

When dealing with reflection of a line or shape or a figure in the coordinate plane, especially if it is reflected across the y- axis, you just have to give the opposite of the given (original) x- coordinate in order to give a symmetric figure.

A reflection on the vertical axis is given by the following transformation:

(x, y) -----------------> (-x, y) ----------------> (x ', Y')

Applying the transformation for the point (-3, 4) we have:

(-3, 4) -----------------> (- (- 3), 4) ----------------> (3, 4)

Therefore, the new ordered pair after the reflection on the vertical axis is given by:

(3, 4)

Answer:

the coordinates of the image of vertex R -3.4 after a reflection across the y-axis are:

(3, 4)

Can someone please help me and give me reasoning explanation for this? I’m confused.
sattari [20]
Answer is a. (-13, 12) b. (4, 11)

Step by step

When your rule is
(x,y) ➡️ (x -8, y +2)

a)
You take your input (-5, 10) and add your input rule to that input to get your output.

Input of x is -5, add x rule -8 = -13
Input of y is 10, add y rule +2 = 12

Your output or new coordinate is (-13, 12)

b) You take your input (12, 9) and add your input rule to that input to get your output.

Input of x is 12, add x rule -8 = 4
Input of y is 9, add y rule +2 = 11

Your output or new coordinate is ( 4, 11)

If your rule changes the process is still the same. Remember to watch adding or subtracting negatives. You can use a graph and plot your input and count out your “rule” to double check your work if you want.

The average height of corn stalks in a field is 71 inches with a standard deviation of 4.3 inches. Sketch a normal curve labelin
kvasek [131]

Answer:

The answer is below

Step-by-step explanation:

The empirical rules states that for a normal distribution, 68% of the data falls within one standard deviation from the mean, 95% falls within two standard deviation from the mean and 99.7% falls within three standard deviations from the mean.

Given that:

mean (μ) = 71 inches, standard deviation (σ) = 4.3 inches

One standard deviation = μ ± σ = 71 ± 4.3 = (66.7, 75.3)

Two standard deviation = μ ± 2σ = 71 ± 2*4.3 = (62.4, 79.6)

Three standard deviation = μ ± 3σ = 71 ± 3*4.3 = (58.1, 83.9)

The graph is attached

A sliver of gold has a volume of 0.678 cm3. What is the mass of this sliver of gold?
Aliun [14]

Answer - 13.098 gm

Description -

Dear student,

As we know Density= \frac{Mass}{Volume}

⇒ Mass = Density * Volume

so multiplying given Volume with the Density of gold ,we can calculate the mass of the gold . Density of gold at room temp. is 19.32 grams per cubic centimeter.

so mass of the sliver of gold = 19.32 * 0.678 = 13.098 (ans)

A group of campers is going to occupy 6 campsites at a campground. There are 16 campsites from which to choose. In how many ways
Pachacha [2.7K]

Answer:

The campsites can be chosen in 5,765,760 different ways.

Step-by-step explanation:

Given that a group of campers is going to occupy 6 campsites at a campground, and there are 16 campsites from which to choose, to determine in how many ways the campsites can be chosen, the following calculation must be performed:

16 x 15 x 14 x 13 x 12 x 11 = X

240 x 182 x 132 = X

240 x 24,024 = X

5,765,760 = X

Therefore, the campsites can be chosen in 5,765,760 different ways.
