Are the graphs 8x+3y=6 and 8x-3y=6 perpendicular

1 answer:

4 0

Lines are perpendicular if the slope of one is the negative reciprocal of the other. In this case the slopes are -8/3 and 8/3, so while negative they are not reciprocal. So no, the two lines intersect but are not perpendicular.

Find the MODE of the data set: 5, 3, 7, 3, 9, 1, 7, 11

abruzzese [7]

Answer:

3 and 7

Step-by-step explanation:

The mode(s) of a data set are the numbers which appear most often. In this set, 3 and 7 both appear twice so they are both modes of the data set.

Part C

Ierofanga [76]

Answer:

see attached

Step-by-step explanation:

GeoGebra conveniently computes the point coordinates of the reflected points. In the attached, the reflections are done in the order listed in the table, so A' is reflected across x; A'₁ is reflected across y; A'₂ is reflected across y=x, and A'₃ is reflected across y=-x. The same notation is used for the other points. The values are listed in order, so you can copy them down the column in your table.

Answer: The initial number of transactions is neither an independent nor a dependent variable.

Step-by-step explanation:

Here, The initial number of transactions that took place in the first hour of day is 10 and the number of transactions doubles every hour after that.

If x represents the number of hours and y represents Number of transaction after x hours.

Therefore, The function which represents the situation is,

$y = 10\times 2^x$

Where x is independent variable, while y is dependent variable.

Since initially x=0, y=10 which is the initial transaction.

And, there is not any impact on the value of 10 by changing the values of x or y, Also 10 is not a variable( because it is a constant value)

Therefore neither it is dependent variable nor it is independent.

Help what is the area of this^^ AND HOW DID YOU DO IT SHOW TOUR STRATEGY

lianna [129]

Answer:

784 cm

Step-by-step explanation:

7*8=56

24*8=192

24*7=168 168*2=336

$7^{2}+24^{2}=625$ $\sqrt{625}$ =25 25*8 = 200

56+192+336+200=784

The function f(t) = 4t^2 − 8t + 6 shows the height from the ground f(t), in meters, of a roller coaster car at different times t

andreev551 [17]

Answer:

C - f(t) = 4(t − 1)^2 + 2; the minimum height of the roller coaster is 2 meters from the ground.

Step-by-step explanation:

Here we're asked to rewrite the given equation f(t) = 4t^2 − 8t + 6 in the form f(t) = a(t - h)^2 + k (which is known as the "vertex form of the equation of a parabola.") Here (h, k) is the vertex and a is a scale factor.

Let's begin by factoring 4 out of all three terms:

f(t) = 4 [ t^2 - 2t + 6/4 ]

Next, we must "complete the square" of t^2 - 2t + 6/4; in other words, we must re-write this expression in the form (t - h)^2 + k.

(To be continued)
