Answer:
Aprox: 465.4 ms/2
Step-by-step explanation:
To find the magnitude of the acceleration the engine must produce, we'll break down the missile's motion into its horizontal and vertical components.
Given:
Initial velocity (V₀) = 1810 m/s
Launch angle (θ) = 20.0°
Target distance (d) = 19,500 m
Target direction (φ) = 32.0°
Time of flight (t) = 9.20 s
First, let's find the horizontal and vertical components of the missile's initial velocity (V₀x and V₀y).
V₀x = V₀ * cos(θ)
V₀y = V₀ * sin(θ)
V₀x = 1810 m/s * cos(20.0°) ≈ 1712.4 m/s
V₀y = 1810 m/s * sin(20.0°) ≈ 618.8 m/s
Now, let's find the horizontal and vertical displacements (dx and dy) of the missile using the time of flight (t) and the target distance (d).
dx = d * cos(φ)
dy = d * sin(φ)
dx = 19,500 m * cos(32.0°) ≈ 16,402.8 m
dy = 19,500 m * sin(32.0°) ≈ 10,236.8 m
Next, let's calculate the acceleration needed in the x-direction (ax) and y-direction (ay) to cover the horizontal and vertical displacements in the given time.
ax = (2 * dx) / t²
ay = (2 * dy) / t²
ax = (2 * 16,402.8 m) / (9.20 s)² ≈ 391.7 m/s²
ay = (2 * 10,236.8 m) / (9.20 s)² ≈ 257.7 m/s²
Finally, to find the magnitude of the acceleration, we can use the Pythagorean theorem:
acceleration magnitude (a) = √(ax² + ay²)
a = √(391.7 m/s²)² + (257.7 m/s²)² ≈ 465.4 m/s²
Therefore, the magnitude of the acceleration that the engine must produce is approximately 465.4 m/s².
If Margo walks 1/4 mile in 1/12 of an hour, what is her unit rate
To find the unit rate, we need to determine how much distance Margo covers in one unit of time. We can do this by dividing the distance by the time.
Distance = 1/4 mile
Time = 1/12 hour
Unit rate = Distance ÷ Time
Unit rate = (1/4 mile) ÷ (1/12 hour)
We can simplify this division by multiplying both the numerator and denominator by the least common multiple of 4 and 12, which is 12.
Unit rate = (1/4 mile) ÷ (1/12 hour) x (12/12)
Unit rate = (3/4 mile) ÷ 1 hour
Unit rate = 3/4 mile per hour
Therefore, Margo's unit rate is 3/4 mile per hour. This means that she can cover a distance of 3/4 mile in one hour of walking.
Answer:
3mph
Step-by-step explanation:
1/12 of an hour will be 5 min. In 5 min she can walk 1/4 mile then in one hour she can walk 1/4 x 12. This means her rate will be 3 miles per hour.
60/12 = 5
12 x 1/4 = 12/4 = 3

what is the slope?
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you want to find out what the slope is, you have to remember what the formula is first....
\(m=\frac{y}{x} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
so in this case -3 would be the \(y_{2}\) because it's the y in the ordered pair and it's the second one. Then one of the 5's would be \(x_{2}\) and 9 would be \(y_{1}\) and then the other 5 would be \(x_{1}\).
now if we plug it in
\(\frac{-3-9}{5-5} =\frac{-12}{0}\)
now we can tell that we can't divide by zero so the slope would be unidentified and that's it.

The time spent higher than 26 meters above the ground is 0.42 minutes. Answer: 0.42
A Ferris wheel is 30 meters in diameter and boarded from a platform that is 4 meters above the ground.
The six o'clock position on the Ferris wheel is level with the loading platform.
The wheel completes 1 full revolution in 2 minutes.
We have to find how many minutes of the ride are spent higher than 26 meters above the ground.
So, let's start with some given data,Consider the height of a person at the six o'clock position = 4 meters
So, the height of a person at the highest point = 4 + 15 = 19 meters (since the diameter is 30 meters, the radius will be 15 meters)
Also, the height of a person at the lowest point = 4 - 15 = -11 meters
Therefore, the Ferris wheel completes one cycle from the lowest point to the highest point and back to the lowest point.
So, the total distance travelled will be = 19 + 11 = 30 meters.
Also, we are given that the wheel completes 1 full revolution in 2 minutes.
We need to calculate the time spent higher than 26 meters above the ground.
So, the angle between the 6 o'clock position and 2 o'clock position will be equal to the angle between the 6 o'clock position and the highest point.
This angle can be calculated as follows:
Angle = Distance travelled by the Ferris wheel / Circumference of the Ferris wheel * 360 degrees
Angle = 30 / (pi * 30) * 360 degrees
Angle = 360 degrees / pi
= 114.59 degrees
So, the total angle between the 6 o'clock position and the highest point is 114.59 degrees.
Now, we need to find out how much time is spent at an angle greater than 114.59 degrees.
This can be calculated as follows:
Time = (Angle greater than 114.59 degrees / Total angle of the Ferris wheel) * Total time taken
Time = (180 - 114.59) / 360 * 2 minutes
Time = 0.42 minutes

The correct answer is option D: A line passes through the point (0, 0) and continues through the point (12, 3)
For the first question:
The table shows a proportional relationship between x and y. To describe what the graph of this proportional relationship would look like, we can examine the given data points.
The data points are (12, 3), (8, 26), and (24, ?). We can observe that as x increases, y also increases. This indicates a positive correlation between the variables. Additionally, we can see that the ratio of y to x remains constant for each data point.
Now, let's analyze the answer options:
A. A line passes through the point (0, 0) and continues through the point (3, 12).
This answer option does not align with the given data because there is no data point with an x-value of 3 and a corresponding y-value of 12.
B. A line passes through the point (0, 0) and continues through the point (2, 8).
This answer option aligns with the given data because (2, 8) is a valid data point from the table, and the line passes through the origin (0, 0).
C. A line passes through the point (0, 0) and continues through the point (6, 24).
This answer option does not align with the given data because there is no data point with an x-value of 6 and a corresponding y-value of 24.
D. A line passes through the point (0, 0) and continues through the point (12, 3).

What percent of 123 is 140? *
Answer:
172.2
Step-by-step explanation:
Answer:
113.8%
Step-by-step explanation:
let the unknown percentage be x%
hence we can re-write the given question as a mathematical equation
"What percent of 123 is 140" can be re-written mathematically as:
x% of 123 = 140
x/100 of 123 = 140
( x/100 )123 = 140 (multiply both sides by 100)
x(123) = 140 x 100
x(123) = 14000 (divide both sides by 123)
x = 14000 / 123
x = 113.8%

The triangle similarity can be proven by three methods, and the AA similarity postulate states that two triangles are similar if and only if their corresponding angles are congruent.
If they have the same shape but different sizes. This is what is known as similarity. In mathematics, there are three ways to prove that two triangles are similar: AA, SAS, and SSS.
In the case of AA similarity postulate, two triangles are similar if and only if two corresponding angles are congruent, meaning they have the same degree measure.
Similarly, if triangle ABC is similar to triangle JKL by AA similarity postulate, it means that the corresponding angles of both triangles are congruent.
Therefore, it is possible that triangle ABC is similar to one or more of the triangles given, but it is not possible to say without further information such as the angles and lengths of the sides.

The numeric value of the exponential expression in this problem is given by the following option:
A. 2^12.
How to obtain the numeric value of the exponential expression?The exponential expression for this problem is defined as follows:
8^x/2^y.
8 is the third power of 2, hence:
8 = 2^3.
When a term is elevated to two of it's powers, the powers are multiplied, hence:
(2^3)^x = 2^(3x).
Meaning that the exponential expression is then written as follows:
8^x/2^y = 2^(3x)/2^y.
When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:
2^(3x)/2^y = 2^(3x - y).
As stated in the problem, the numeric value of the expression 3x - y is given as follows:
3x - y = 12.
Hence the entire expression is simplified as follows:
2^(3x - y) = 2^12.

What is the relative change from Ohio to Indiana if Indiana has 6546 new mathematics teachers and Ohio has 4392 new mathematics teachers?
The relative change from Ohio to Indiana in terms of new mathematics teachers is approximately 49.08%. This indicates that Indiana has experienced a significant increase compared to Ohio in the number of new mathematics teachers.
To calculate the relative change from Ohio to Indiana in terms of new mathematics teachers, we need to determine the percentage increase or decrease in the number of teachers between the two states.
The relative change can be calculated using the formula:
Relative Change = (New Value - Old Value) / Old Value * 100
Let's apply this formula to the given data:
Ohio: Old Value = 4392
Indiana: New Value = 6546
Relative Change = (6546 - 4392) / 4392 * 100
Simplifying the equation:
Relative Change = 2154 / 4392 * 100
Relative Change ≈ 0.4908 * 100
Relative Change ≈ 49.08%
The relative change from Ohio to Indiana in terms of new mathematics teachers is approximately 49.08%. This indicates that Indiana has experienced a significant increase compared to Ohio in the number of new mathematics teachers.
