Step-by-step explanation:

The number of points of intersection for the graphs of the equations is infinite.

Point of intersection refers to the point at which two lines intersect on a graph. The graph of the equation refers to the visual demonstration of the equation obtained by plotting all the points of an equation on a graph. If there is only one variable, the graph is on a number line. If there are two variables, the graph is on the coordinate plane. If there are three variables, the graph is in three-dimensional coordinates.

Simplifying the given equations:

i) x/2 + 5y = 6

x + 10y = 12

ii) 3x + 30y = 36

3(x + 10y) = 36

x + 10y = 12

As the equations are equal lines, they will intersect at infinite times.

Note: The question is incomplete. The complete question probably is: How many intersections are there of the graphs of the equations below? x/2 + 5y = 6 3x + 30y = 36 none one two infinitely many

Step-by-step explanation:

Answer:

Only -lxl = -3 works

Step-by-step explanation:

The other options don't work because they all have numbers inside of the absolute value brackets.  You would always get a positive end value when the absolute value equation is applied.

The last one is the only one that works because the negative is outside of the absolute value bracket.  Therefore, if you plug in 3 for x, it will give you -3.

Answer: The answer is x=7.

Step-by-step explanation: Now let's solve your equation step-by-step:

\(\frac{1}{2}x+\frac{6}{3}=x-\frac{3}{2}\).

Step 1. Simplify the both sides of the equation: \(\frac{1}{2}x+2=x+\frac{-3}{2}\).

Step 2. Subtract x from the both sides: \(\frac{1}{2}x+2-x=x+\frac{-3}{2}-x\) to

\(\frac{-1}{2}x+2=\frac{-3}{2}\).

Step 3. Subtract 2 from the both sides: \(\frac{-1}{2}x+2-2=\frac{-3}{2}-2\) to

\(\frac{-1}{2}x=\frac{-7}{2}\).

Last but not least is step 4. Multiply the both sides by 2/(-1):

\((\frac{2}{-1})*(\frac{-1}{2}x)=(\frac{2}{-1})*(\frac{-7}{2})\) to \(x=7.\) I hope your answer is very helpful, please mark me as brainliest, and have a happy holidays! :D

Step-by-step explanation:

The angles on the same side of the isoceles trapezoid are equal and the opposite sides are supplementary to the other angles.

To eliminate the roots in 1.1 and 1.2, we can use trigonometric substitution. In 1.1, we can substitute x = 4 sin(theta) to eliminate the root of 4. In 1.2, we can substitute z = 7 sin(theta) to eliminate the root of 7.

1.1. V64+2 + 1 We can substitute x = 4 sin(theta) to eliminate the root of 4. This gives us:

V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3 1.2. V4z2 – 49

We can substitute z = 7 sin(theta) to eliminate the root of 7. This gives us:

V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta) (2 – 1) = 7 sin(theta)

Here is a more detailed explanation of the substitution:

In 1.1, we know that the root of 4 is 2. We can substitute x = 4 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 2.

When we substitute x = 4 sin(theta), the expression becomes V64+2 + 1 = V(16 sin^2(theta) + 2 + 1) = V16 sin^2(theta) + V3 = 4 sin(theta) V3

In 1.2, we know that the root of 7 is 7/4. We can substitute z = 7 sin(theta) to eliminate this root. This is because sin(theta) can take on any value between -1 and 1, including 7/4.

When we substitute z = 7 sin(theta), the expression becomes: V4z2 – 49 = V4(7 sin^2(theta)) – 49 = V28 sin^2(theta) – 49 = 7 sin(theta) V4 – 7 = 7 sin(theta)

Answer: 60/61

Step-by-step explanation:

The measure of the two angles will be x > 25° and y = 180° - x°.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The two lines are parallel and the third line is a transversal line.

If one angle is greater than 25°. Then the other angle is given as,

Let the angles be 'x' and 'y'. Then angles are supplementary angles. Then the inequality is given as,

x > 25°               ...1

x + y = 180°

y = 180° - x       ...2

From equations 1 and 2, then we have

y = 180° - x

The measure of the two angles will be x > 25° and y = 180° - x°.

Answer:

Thus, \(y=-\sqrt{x+3}\) represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

Step-by-step explanation:

Consider the function

y = f(x)

The rule of horizontal translation

y = f(x-h)

When 'h' is positive, the function is shifted to the right.

When 'h' is negative, the function is shifted to the left.

The rule of implying vertical reflection across the x-axis

y = -f(x)

Applying the rule:

We know that the square root function is

\(y=\sqrt{x}\)

We know that if the graph would be reflected across the x-axis, then

\(y=-\sqrt{x}\)

We know that   is horizontally translated or shifted 3 units to the left, it implies  +

The drowned forests in Cascadia have provided scientists with valuable insights into the size of past earthquakes in the region. In a long answer, it can be explained that these forests were buried by sediment and submerged by sea level rise, which helped preserve the trees and their growth rings.

By studying the width of these rings, scientists can determine the age of the trees and when they were submerged. By comparing this data with other geological records, scientists have been able to identify periods of seismic activity and estimate the size of the earthquakes that caused the submergence of the forests. In particular, the discovery of a submerged forest near Copalis Beach in Washington provided evidence of a massive earthquake that occurred in the year 1700, which was estimated to have a magnitude of approximately 9.0 on the Richter scale.

Overall, the drowned forests in Cascadia have helped scientists better understand the history of earthquakes in the region and the potential for future seismic activity.

The drowned forests in Cascadia showed scientists that past earthquakes in the region were larger than previously thought. These drowned forests, which are located along the Pacific Northwest coast, provide evidence of past earthquakes by showing evidence of sudden subsidence and submergence.

Scientists have studied the growth rings of these submerged trees, which have been dated to determine when they were alive. By analyzing the sediment layers in which the trees were buried, researchers can estimate the magnitude and timing of past earthquakes. The findings suggest that the Cascadia subduction zone, which runs from northern California to southern British Columbia, may have experienced much larger earthquakes than previously believed.

Specifically, the drowned forests indicate that earthquakes of magnitude 8.5 or higher have occurred in the region in the past. These findings are important for earthquake preparedness and can help inform building codes and other safety measures in the Pacific Northwest.

Answer:

36/5 as a decimal is 7.2

Step-by-step explanation:

In the fraction 36/5, 36 is the numerator and 5 is the denominator, the fraction bar means "divided by". Therefore, the fraction 36/5 is same as "36 divided by 5" or "36 ÷ 5".

When we calculated 36 divided by 5, we found that 36/5 in decimal form is:

36 ÷ 5 = 7.2

Therefore, the decimal form of 36/5 is 7.2

The test statistic for this sample is z = (0.254 - 0.203) / (p_hat * (1 - p_hat) * (1/n1 + 1/n2))

Based on the given information, we can set up the hypotheses as follows:

Null hypothesis: p1 - p2 = 0
Alternative hypothesis: p1 - p2 > 0

where p1 represents the proportion of successes in the first population and p2 represents the proportion of successes in the second population.

Since the sample sizes are large (n1 and n2 are not given, but we can assume they are large enough for the normal approximation to hold), we can use the normal distribution to approximate the sampling distribution of the difference in sample proportions.

The test statistic for this sample can be calculated as follows:

z = (p1 - p2) / sqrt(p_hat * (1 - p_hat) * (1/n1 + 1/n2))

where p_hat = (x1 + x2) / (n1 + n2), x1 and x2 are the number of successes in the two samples respectively.

Plugging in the given values, we get:

p_hat = (0.254n1 + 0.203n2) / (n1 + n2)
z = (0.254 - 0.203) / sqrt(p_hat * (1 - p_hat) * (1/n1 + 1/n2))

Since the significance level is not given, we cannot determine the critical value for the test. However, we can use the test statistic to calculate the p-value for the test, which is the probability of observing a difference in sample proportions as extreme as the one we observed (or more extreme) under the null hypothesis.

Once we have the p-value, we can compare it to the significance level to make a decision about whether to reject or fail to reject the null hypothesis.

Note: It is important to mention that using the normal approximation without the continuity correction may not always be accurate, especially when the sample sizes are small or the proportion of successes is close to 0 or 1. In such cases, it is recommended to use other methods (such as exact tests or simulation) that do not rely on the normal approximation.

The graph that gives the best representation of the scenario is: option 1 (A).

The first graph is the correct one that best represents the scenario because it starts at the point of origin (0, 0), which means the bird covers not distance at zero time when it is still at its nest.

As the bird flies, distance increases with time till it stopped at a point to eat.. This is represented by horizontal line, meaning time increased but distance from the nest remains the same.

The upward slope from the spot represents the further distance the bird is flying in search for more food.

f(x) = 4x⁴- 7x²+ x + 25

Possible rational roots will be,

\(\frac{\pm \text{Factors of constant term '25'}}{{\pm \text{Factors of leading coefficient '4'}}}\)

For the given function,

Possible rational roots = \(\frac{\pm 1, 5, 25}{\pm 1,2}\)

Therefore, \(-\frac{2}{5}\) is not the possible root.

Option (2)

f(x) = 9x⁴- 7x²+ x + 10

Possible rational roots = \(\frac{\pm 1,\pm 2,\pm 5,\pm10}{\pm 1,\pm3,\pm9}\)

Therefore, \(-\frac{2}{5}\) is not the possible root.

Option (3)

f(x) = 10x⁴- 7x²+ x + 9

Possible rational roots = \(\frac{\pm1, \pm3, \pm9}{\pm 1,\pm2,\pm5,\pm10}\)

Therefore, \(-\frac{2}{5}\) is not the possible root.

Option (4)

f(x) = 25x⁴- 7x²+ x + 4

Possible rational roots = \(\frac{\pm 1,\pm2,\pm5}{\pm1,\pm5,\pm 25}\)

                                      = \(\pm1,\pm2,\pm5,\pm\frac{1}{5},\pm\frac{1}{25},\pm\frac{2}{5},\pm\frac{2}{25}\)

Therefore, \(-\frac{2}{5}\) is the possible rational root.
