Identify the discriminant value of the quadratic equation m² + 18m + 17 = 0.
Answer:
Step-by-step explanation:
The discriminant value (denoted by Δ) of a quadratic equation in the form of ax² + bx + c = 0 is given by the expression b² - 4ac.
For the quadratic equation m² + 18m + 17 = 0, a = 1, b = 18, and c = 17. Substituting these values into the expression for the discriminant, we get:
Δ = b² - 4ac
Δ = (18)² - 4(1)(17)
Δ = 324 - 68
Δ = 256
Therefore, the discriminant value of the quadratic equation m² + 18m + 17 = 0 is 256.

Find m1 if m5 =142 and m4=65
The value of m∠1 is 103°. The solution has been obtained by using the angle sum property.
What is the angle sum property?
The angle sum property of a triangle states that the sum of the three internal angles of a triangle is 180 degrees.
We are given that m∠5 = 142° and m∠4 = 65°.
Since m∠5 and m∠2 lie on a straight line so, they form a linear pair.
So,
⇒ m∠5 + m∠2 = 180°
⇒ 142° + m∠2 = 180°
⇒ m∠2 = 38°
We know that sum of angles of a triangle is 180°.
So,
⇒ m∠3 + m∠4 + m∠2 = 180°
⇒ m∠3 + 65° + 38° = 180°
⇒ m∠3 + 103° = 180°
⇒ m∠3 = 77°
Now, since m∠3 and m∠1 lie on a straight line so, they form a linear pair.
So,
⇒ m∠3 + m∠1 = 180°
⇒ 77° + m∠1 = 180°
⇒ m∠1 = 103°
Hence, the value of m∠1 is 103°.

A plane can fly 420 miles in the same time as it takes a car to go 150 miles. If the car travels 90 mph slower than the plane, find the speed of the plane. Using r as your variable to represent the speed of the plane in miles per hour, write an equation using the information above that can be solved to find the answer to this problem.
Answer:
Step-by-step explanation:
rate of the plane be x
distance traveled by plane = 420 miles
time taken by plane = 420/x
distance traveled by car =120 miles
rate of car = x-120
time taken by car = 120 / x-100
the time taken by both are same
420/x = 120/ x-100
420(x-100)=120x
420x-42000 = 120x
420x-120x=42000
300x= 42000
x=42000/300
x=140 mph the speed of the plane

Oy> 3x+1
O y≤7x-1
The inequality that has a dashed boundary line when graphed is:
y > 3x + 1
What is inequality?In mathematics, an inequality is a statement that two quantities are not equal or do not have the same value. In other words, it is a statement that compares two values, expressing that one value is greater than, less than, or not equal to the other value. An inequality is denoted by symbols such as < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to).
What is Dashed boundary?In mathematics, a dashed boundary refers to a boundary line that is graphed as a dashed line rather than a solid line. The use of a dashed line is typically used to indicate that the boundary itself is not included in the set of solutions of an inequality or equation.
In the given question,
The inequality that has a dashed boundary line when graphed is:
y > 3x + 1
The reason for this is that when graphed, the boundary line of the inequality y > 3x + 1 is a straight line, but it is dashed instead of solid. This is because the inequality is strict, meaning that the boundary line itself is not included in the set of solutions. On the other hand, if the inequality had been y ≥ 3x + 1, the boundary line would have been a solid line because the inequality is non-strict and includes the boundary line itself as a solution.

B: approximately when does the first rocket land
C: what is the approximate interval during which all three rockets are in the air
The vertical shape of the graph will be the same as that of the first rocket, assuming both rockets have the same initial velocity and acceleration.
What is the interval during which all three rockets?1.I agree with Serena that we can draw the graphs for the other two rockets by shifting the functions. We can use the same equation and just adjust the values of the horizontal and vertical shifts.
2. The equation f(t) = -6t² represents a quadratic function, which has a parabolic shape when graphed. If we apply a transformation to this function, such as a vertical or horizontal shift, the shape of the graph will change accordingly.
3. The term 82.14 likely represents the maximum height achieved by the rocket, since the equation f(t) = -6t² gives the height of the rocket as a function of time. The value of h(t) = 82.14 corresponds to a specific time when the rocket reaches its maximum height.
4. If the second rocket is launched 3 seconds after the first one, the graph of the second rocket will be shifted horizontally by 3 units to the right compared to the graph of the first rocket. This represents a time delay of 3 seconds between the two launches.
5. The equation of the second rocket would be f(t) = -6(t-3)², assuming that the second rocket has the same initial velocity and acceleration as the first rocket but is launched 3 seconds later.
6. Since the third rocket is launched 3 seconds after the second rocket and from a tall platform, its graph will be shifted horizontally to the right by 6 units compared to the graph of the first rocket.
9. A: Based on the graph, the third rocket was launched at approximately 5:20 PM.
B: Based on the graph, the first rocket lands at approximately 5:15 PM.
C: Based on the graph, all three rockets are in the air between approximately 5:10 PM and 5:25 PM, so the approximate interval during which all three rockets are in the air is 15 minutes.
Therefore, spends an additional 6 seconds in the air before landing. The vertical shape of the graph will depend on the specifics of the rocket's launch and trajectory.

A ball that is thrown upward follows the path h(t)=-t^2+8t+32, where h(t) represents the height of the ball above the ground at time t, and t represents the time since the ball was thrown. How high above the ground did the ball reach? show work
Answer:
Step-by-step explanation:
To find the maximum height of the ball, we need to find the vertex of the parabolic function h(t) = -t^2 + 8t + 32. The vertex represents the highest point of the parabolic curve.
The x-coordinate of the vertex is given by the formula x = -b/2a, where a and b are the coefficients of the quadratic equation. In this case, a = -1 and b = 8, so we have:
x = -b/2a = -8/(2(-1)) = 4
Therefore, the vertex occurs at time t = 4.
To find the y-coordinate of the vertex, we evaluate the function at t = 4:
h(4) = -4^2 + 8(4) + 32 = 16 + 32 = 48
Therefore, the ball reaches a maximum height of 48 feet above the ground.

The length of the side opposite to the 42 degree angle in the right triangle is approximately 3.4 units.
Describe Triangle?The angles of a triangle are the angles formed by its sides. The sum of the angles of a triangle is always 180 degrees, which is a fundamental property of this shape. There are different types of triangles, based on their side lengths and angle measures. For example:
A scalene triangle has three sides of different lengths and three different angles.
An isosceles triangle has two sides of equal length and two equal angles.
An equilateral triangle has three sides of equal length and three equal angles.
A right triangle has one angle that measures 90 degrees (a right angle), and the side opposite to it is called the hypotenuse.
Triangles have many important properties and applications in mathematics, physics, and engineering. They can be used to calculate distances, angles, areas, volumes, and many other quantities. Triangles are also used in the construction of buildings, bridges, and other structures, as well as in art, design, and other fields.
We can use the trigonometric ratio of sine to solve for x:
sin(42) = opposite/hypotenuse
sin(42) = x/5
To solve for x, we can multiply both sides by 5 and simplify:
x = 5*sin(42)
x ≈ 3.4 (rounded to the nearest tenth)
Therefore, the length of the side opposite to the 42 degree angle in the right triangle is approximately 3.4 units.

Step 1 of 2 : Find the slope and the y-intercept. Express the intercept as an ordered pair. Simplify your answer.
The slope of the function is -29 and the y-intercept is the point (0, 2).
What is function ?
In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. It is a rule that assigns to each element of a set (called the domain) exactly one element of another set (called the range).
To find the slope and y-intercept of the function p(x) = 2 - 29x, we can write it in the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
So, by comparing p(x) = 2 - 29x with y = mx + b, we can see that:
m = -29 (the coefficient of x)
b = 2 (the constant term)
Therefore, the slope of the function is -29 and the y-intercept is the point (0, 2).

Blood pressure readings are normally distributed. The mean systolic blood pressure is 120 and the standard deviation is 8. If a medical researcher randomly selects a sample of 20 people, what is the probability that the mean blood pressure for this sample will be greater than 123?
Answer:
To solve this problem, we can use the central limit theorem and the standard normal distribution.
The central limit theorem states that the distribution of sample means is approximately normal, with a mean equal to the population mean, and a standard deviation equal to the population standard deviation divided by the square root of the sample size.
Let X be the systolic blood pressure of an individual in the population. We know that X is normally distributed with a mean of 120 and a standard deviation of 8.
Let Y be the sample mean blood pressure of a sample of 20 individuals. Then Y is also normally distributed, with a mean of 120 and a standard deviation of 8 / sqrt(20) = 1.7889.
We want to find the probability that the sample mean blood pressure is greater than 123. We can standardize this value using the standard normal distribution as follows:
Z = (Y - 120) / (8 / sqrt(20))
P(Y > 123) = P(Z > (123 - 120) / (8 / sqrt(20)))
= P(Z > 1.3363)
Using a standard normal distribution table or calculator, we can find that the probability of Z being greater than 1.3363 is approximately 0.0918.
Therefore, the probability that the mean blood pressure for a sample of 20 people will be greater than 123 is approximately 0.0918.

For forty pencils, a refundable charge of Rupees ($1.01) might be required.
Here,
To evaluate the prices, we need to use the same units.
Since 0.9144 metres make up one yard, we can convert the cost of the rope at the hardware shop to dollars per metre as follows:
=> 0.89 dollars/yard * 1 yard/0.9144 meters = 0.97 dollars/meter
b) We must change the units to yards or metres in order to evaluate the costs of 650 feet of rope. 650 feet is equivalent to 3 yards, which is:
=> 650 feet x 3 feet per yard = 216.67 yards
The hardware store's price for the cord is:
=> 192.5 dollars ($0.89/yard x 216.67 yards)
At the timber yard, the price of the rope is:
=> (216.67 yards * 0.9144 meters/yard) * 0.94 dollars/meter = 177.8 dollars.
Jim would therefore save:
=> 192.5 dollars - 177.8 dollars = 14.7 dollars.

It is observed that 3 out of every 5 drills made at an oil-drilling site strike oil. The results from 50-simulation trials of the model showed 1 out of 5 drills
are guaranteed to strike oil. What is the hypothesis, and based on the results from the simulation trials, what should be concluded about the
hypothesis?
A. The hypothesis is that at least 1 out of 5 drills will strike oil. Based on the results from the simulation trials, the hypothesis should be rejected.
B. The hypothesis is that at least 1 out of 5 drills will strike oil. Based on the results from the simulation trials, it can be concluded that the hypothesis is
correct.
C. The hypothesis is that at least 3 out of 5 drills will strike oil. Based on the results from the simulation trials, the hypothesis should be rejected.
D. The hypothesis is that at least 3 out of 5 drills will strike oil. Based on the results from the simulation trials, it can be concluded that the hypothesis is
correct.

Confidence intervals are constructed to estimate the population parameter (like the mean) a specified proportion of the time. The upper and lower interval estimates are often described as the
The upper and lower interval estimate are often describe as associated with a specific level of confidence.
What is Interval Estimate?In statistics, interval estimate is the process of determining the interval, or range of values, within which a parameter—such as the mean (average) of a population—is most likely to fall.
The interval encompassing a population parameter is determined by computing the statistic from values obtained from a random sample chosen from the population and by using the understanding (derived from probability theory) of how accurately sample properties reflect those of the full population.
The possibility that the estimated confidence interval estimate will include the genuine population parameter is frequently referred to as the confidence level.
