We can identify vertical lines by seeing if two points that fall on the line have the same x-coordinate.

If they do, then it is a vertical line.

The slope of vertical lines are always undefined.

We're given the following points:

These points have the same x-coordinate, revealing that this is a vertical line. Therefore, it has an undefined slope.

Answer: 4.95

Step-by-step explanation:

54.25÷6.2−3.8=

54.25/6.2−3.8=

8.75-3.8=

8.75-3.80=

8-3+0.75-0.80=

5-0.05=4.95

The quadratic equations are y = 2(x + 4)(x - 5) and y = -2(x + 4)(x - 5)

From the question, we have the following parameters that can be used in our computation:

Solutions = -4 and 5

A quadratic equation is represented as

y = a * (x - solutions)

Using the above as a guide, we have the following:

y = a(x + 4)(x - 5)

When the parabola opens up, a > 1

So, an instance is

y = 2(x + 4)(x - 5)

When the parabola opens down, a < 1

So, an instance is

y = -2(x + 4)(x - 5)

Answer:   To find the average rate of change, divide the change in y-values by the change in x-values

Step-by-step explanation:

Answer:

GHJ = 19

JHK = 54

Step-by-step explanation:

first we setup an equation 73=x+2+3x+3 and solve for x

step 1 combine like terms

73=4x+5

step 2 subtract each side by 5

68=4x

step 3 divide each side by 4

x=17

then if we want to find what each angle equals we just plug in 17 to x

17+2=19 so angle GHJ equals 19

3x17=51+3=54 so angle JHK equals 54

To find the surface area of a rectangular prism you must multiple the length and the width. You can choose the top and do 2(L*W) and one of the square sides 2(L*W) and the front 2(L*W) and add it all up.

2(L*W)+2(L*W)+2(L*W)= surface area

There is a 2 because there are two side of a rectangular that are the same. Since there are 6 sides on a rectangle. Only 3 pairs are similar.

Answer: 5/7

Step-by-step explanation: 7/5 is 1.4, which doesn't make sense as an answer here because it's a number greater than one, while we're looking for a number that can be made into a simple fraction, decimal or percent. 5 x 7 = 35, which also doesn't make sense for the same reasons but also because the answer is a division problem and this is multiplication. 7/7 equals one, which doesn't make sense because Melissa hasn't finished 100% of her homework yet.

The location of √ 7 on a number line between 2 and 3.

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in primary mathematics. Every number line point is considered to correspond to a real number and every real number to a number line point.

A number line is a long straight line with numbers marked at equal intervals. On a number line, we can argue that as we move to the right, the value of numbers increases. This signifies that the numbers on the right are more than those on the left.

A number line shows how numbers are related. It's a line with check marks next to each number. The numerals get smaller as you move left on the number line. The numbers grow larger as you move closer to the number line.

In this case, ✓7 is 2.65. This number can be found between 2 and 3. This should be the true statement since the options aren't given.

All you need to know to solve this problem is the pythogorean theorem. If you draw an imaginary line to make a triangle and a rectangle, you already know the height is 4. To find the base, you know that the bottom length is 9 and the top is 6 so 9-6 =3, which is the length of only the left side of the imaginary line.

So 4^2 + 3^2 = c^2

25 = c^ 2

5 = c

Answer:

hours

Step-by-step explanation:

12 hours on an analog clock. there are 60 minutes in an hour, not 12.

Answer:

Please check the explanation.

Step-by-step explanation:

Let the coordinates of the point F be (x, y).

When a point F(x, y) is reflected over the x-axis, the x-coordinate of the point F remains the same, and the y-coordinate of the point reverses the sign.

Thus, the rule of reflection over the x-axis:

F(x, y)   →    F'(x, -y)

Here,

F'(x, -y) would be coordinates of point F after the reflection over the x-axis.

Let say, the point F(1, 2).

The coordinate of the point F after the reflection over the x-axis would be:

F(1, 2)   →    F'(1, -2)

Thus, F'(1, -2) would be the coordinates of point F after the reflection over the x-axis.

Using transformation rules, it is found that the correct option is:

Rodney can sue the organizers of the ice hockey match for negligence. The reason is that the organizers did not provide proper safety measures even after knowing that the spectators are at high risk of injury.

In the given situation, the one-meter high hard clear plastic screen surrounding the rink was not enough to protect the spectators. The organizers of the ice hockey match have the responsibility of ensuring the safety of the spectators. While they did put up a hard clear plastic screen, it was not enough to protect Rodney. They should have taken additional measures such as erecting a higher barrier or providing protective gear to the spectators. Since Rodney has been attending the matches for fifteen years and has only seen a puck hit into the crowd on ten occasions.

The organizers knew the potential risk and should have taken steps to prevent such an incident. The fact that no one was injured in the past does not absolve the organizers of their responsibility. It is their duty to ensure the safety of the spectators at all times. In this case, they failed to take adequate safety measures, which resulted in Rodney's injury. Therefore, Rodney has a valid case of negligence against the organizers of the ice hockey match. In conclusion, Rodney can sue the organizers of the ice hockey match for negligence because they failed to provide proper safety measures to prevent an incident such as this from occurring. Therefore, Rodney has a strong case of negligence against the organizers of the ice hockey match, and he is likely to succeed in his claim. The organizers should take this opportunity to review their safety measures and ensure that such incidents are prevented in the future.

Based on the given informations, the change in y as t changes from 1 to 6 is approximately 3.870. Therefore the correct option is (A).

To find the change in y as t changes from 1 to 6, we need to integrate the given function with respect to t over the interval [1, 6] and then find the difference between the values of the integral at the two endpoints.

∫₁⁶ 6e\(.^{(-0.08(t-5)^2)}\)  dt

We can use the substitution u = t - 5 to simplify the integral:

∫₋₄¹ 6e\(.^{(-0.08u^2)}\)  du

Unfortunately, there is no closed-form solution for this integral. We can use numerical integration methods, such as Simpson's rule or the trapezoidal rule, to approximate the integral. Using Simpson's rule with a step size of 1, we get:

∫₋₄¹ 6e\(.^{(-0.08u^2)}\) du ≈ 3.870

Therefore, the change in y as t changes from 1 to 6 is approximately 3.870, which corresponds to option (A).

Answer:60

Step-by-step explanation:

When the full moon is at position 3, positions 9 and 12 experience low tide.

The correct option is 9 and 12.

The positions of the moon and the sun have an impact on the tides of the Earth's oceans.

What is a tide?

Tides are the regular rise and fall of the sea level due to the gravitational influence of the Moon and the Sun on the Earth. The gravitational pull of the Moon on the Earth produces two tidal bulges, one on the side of the Earth facing the Moon and one on the side opposite the Moon. The Moon's gravitational pull causes high tides in the area of the bulge and low tides elsewhere on the Earth. The tides are affected by the location of the Sun and the Moon as they orbit the Earth.

In order to determine which two positions experience low tide, the Moon's position must be considered.

When the Moon is directly overhead or opposite to the Earth, its gravitational pull has the greatest effect, causing the greatest difference between high and low tides, also known as spring tides.

When the Moon is at a 90-degree angle to the Earth, its gravitational pull is less, causing a smaller difference between high and low tides, also known as neap tides.

In the given case, when the full moon is at position 3, positions 9 and 12 experience low tide.

Thus, the correct option is 9 and 12.
