4(m + 2) = 40
solve the equation please
Answers
Answer:
m = 9.5
Step-by-step explanation:
Use the distributive property, so now the equation should look like:
4m + 2 = 40
-2 -2
-------------------
4m = 38
÷4 ÷4
-----------------
m = 9.5
4m + 8 = 40
4m = 40 - 8
4m = 32

A particle is moving according to the position function \( s(t)=(4 t+1)^{3 / 2} \), where \( s(t) \) is measured in centimeters and \( t \) in seconds. Find the acceleration of the particle at \( t=2 seconds. find
"
Answers
The acceleration of the particle at \(t = 2\) seconds is \(4\) cm/s².
To find the acceleration of the particle at \(t = 2\) seconds, we need to differentiate the position function twice with respect to time. First, let's differentiate the position function \(s(t)\) once to find the velocity function \(v(t)\). Using the chain rule, we have:
\(\(v(t) = \frac{d}{dt}[(4t+1)^{3/2}]\)\)
To simplify the differentiation, we can rewrite the function as\(\(v(t) = (4t+1)^{3/2}\)\) . Applying the power rule, the derivative becomes:
\(\(v(t) = \frac{3}{2}(4t+1)^{1/2} \cdot 4\)\)
Simplifying further, we have:
\(\(v(t) = 6(4t+1)^{1/2}\)\)
Next, we differentiate the velocity function \(v(t)\) to find the acceleration function \(a(t)\):
\(\(a(t) = \frac{d}{dt}[6(4t+1)^{1/2}]\)\)
Using the power rule again, we get:
\(\(a(t) = 6 \cdot \frac{1}{2}(4t+1)^{-1/2} \cdot 4\)\)
Simplifying further, we have:
\(\(a(t) = 12(4t+1)^{-1/2}\)\)
Now we can find the acceleration at \(t = 2\) seconds by substituting \(t = 2\) into the acceleration function:
\(\(a(2) = 12(4 \cdot 2 + 1)^{-1/2}\)\)
\(\(a(2) = 12(9)^{-1/2}\)\)
Simplifying the expression, we have:
\(\(a(2) = \frac{12}{3} = 4\) cm/s²\)
Therefore, the acceleration of the particle at \(t = 2\) seconds is \(4\) cm/s².

A butt joint design with a 90° V groove angle and 1/16-in. root faces is commonly used for welding thicker materials. Aluminum, being 3/16-in. thick, falls within this range. The V groove angle helps create a strong weld joint, and the 1/16-in. root faces allow for tight butt joints, ensuring good fusion between the materials. The V groove angle determines the shape and depth of the weld, while the root face refers to the gap between the materials to be welded. In this case, the 90° V groove angle and 1/16-in.
Option A, 3/16-in.-thick aluminum, is the most appropriate choice for a butt joint design requiring a 90° V groove angle and 1/16-in. root faces tightly butted against each other. It's important to consult welding codes, specifications.

(where t has units of seconds). What is the speed of the particle in the instant when it is moving parallel to the y-axis?
Answers
The speed of the particle when it is moving parallel to the y-axis is approximately 17.88 m/s.
When the particle moves parallel to the y-axis, its velocity component in the x-direction is zero. Therefore, we need to find the value of t for which the x-component of the velocity becomes zero.
Given that the x-component of the velocity is (2t - 8), we set it equal to zero and solve for t:
2t - 8 = 0
2t = 8
t = 4
At t = 4 seconds, the particle is moving parallel to the y-axis. To determine the speed of the particle at this instant, we calculate the magnitude of its velocity:
v = √[(2t - 8)^2 + ((2/t^2) - 18)^2]
v = √[(2(4) - 8)^2 + ((2/(4^2)) - 18)^2]
v = √[0^2 + ((2/16) - 18)^2]
v = √[0 + (-17.875)^2]
v ≈ 17.88 m/s
Therefore, the speed of the particle when it is moving parallel to the y-axis is approximately 17.88 m/s.

Write an equation to express the relationship between hands, LaTeX: hh, and cubits, LaTeX: cc. Explain your reasoning under your equation.

Answer: 1 hand = 0.22... cubits.
Step-by-step explanation:
We want to write the relation between hands and cubits.
We know that there are 9 hands in 2 cubits.
So we can write:
9 hands = 2 cubits.
Now, we want to have an unit in the left side (so we can see how many cubits are equal to exactly one hand).
Then we can divide by 9 in both sides of the equality.
(9 hands)/9 = (2 cubits)/9
1 hand = 0.22... cubits.

find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. round to the nearest tenth, if necessary.1. 40a. 40, 140 b. 140, 220 c. 9, 171 d. 4.5, 175.5
Answers
The value of interior angle and the exterior angle will be 9, 140 degree.
Hence, option (a) is correct choice.
(a) 40, 140
An exterior angle of a regular polygon with 40 sides is equal to 360 divided by the number of sides, which is 360/40 = 9 degrees.
An interior angle of a regular polygon with 40 sides is equal to (180(n-2))/n,
where n is the number of sides,
which is (180(40-2))/40 = 140 degrees.
So the answer is: 9, 140.
(b) 140, 220
The exterior angle of a regular polygon with 40 sides is equal to 360 divided by the number of sides,
which is 360/40 = 9 degrees.
An interior angle of a regular polygon with 40 sides is equal to (180(n-2))/n,
where n is the number of sides, which is (180(40-2))/40 = 140 degrees.
So the answer is: 9, 140.
(c) 9, 171
The exterior angle of a regular polygon with 9 sides is equal to 360 divided by the number of sides, which is 360/9 = 40 degrees.
An interior angle of a regular polygon with 9 sides is equal to (180(n-2))/n,
where n is the number of sides, which is (180(9-2))/9 = 140 degrees.
So the answer is: 40, 140.
(d) 4.5, 175.5
This answer is incorrect.
The exterior angle of a regular polygon with 4.5 sides is not possible since the number of sides in a polygon must be a positive integer.
The interior angle of a regular polygon with 4.5 sides is not possible since the number of sides in a polygon must be a positive integer.

The main idea behind statistical inference is that through the use of sample data, we are able to draw conclusions about the population from which the data was drawn (option c).
Statistical inference allows us to make inferences and draw conclusions about a larger population based on the analysis of a smaller representative sample.
By collecting data from a sample, we can use statistical methods to analyze and summarize the information. These methods include estimating population parameters, testing hypotheses, and making predictions.
The key assumption underlying statistical inference is that the sample is representative of the larger population, allowing us to generalize the findings to the population as a whole.
Statistical inference provides a way to make reliable and informed decisions, identify patterns and relationships, and make predictions about future observations based on the available data. It allows researchers, scientists, and decision-makers to make evidence-based conclusions and draw meaningful insights from limited observations.

when the second hand moves from halfway between the 1 and the 2 to 4/5 of the way from the 1 to the 2 what is the measure of the arc
Answers
The second hand moves 6 degrees in one second, it will take it: 294/6 = 49 seconds to move from halfway between 1 and 2 to 4/5 of the way from 1 to 2.
The measure of the arc is 144 degrees.
When the second hand of the clock moves from halfway between the 1 and the 2 to 4/5 of the way from the 1 to the 2, it moves a total of 144 degrees.
This can be calculated as follows: The second hand of a clock completes one full revolution every 60 seconds or 1 minute.
This means that in 1 second, it moves 360/60
= 6 degrees.
To find the measure of the arc when the second hand moves from halfway between the 1 and the 2 to 4/5 of the way from the 1 to the 2, we need to find the difference between the two positions in degrees.
The position halfway between the 1 and the 2 is 1.5 on the clock face.
This is equivalent to 45 degrees (since the clock face is divided into 12 hours, each hour marking is 30 degrees apart, so halfway between 1 and 2 is 30+15 = 45 degrees).
4/5 of the way from the 1 to the 2 is 4/5 x 30 = 24 degrees from the 1 mark.
Therefore, the total angle between halfway between 1 and 2 and 4/5 of the way from 1 to 2 is:
24 + (360 - 45)
= 339 degrees.
However, we need to find the difference between these two positions, not the total angle.
Therefore, we need to subtract the position of the second hand at halfway between 1 and 2 from the position at 4/5 of the way from 1 to 2:
339 - 45
= 294 degrees.
Since the second hand moves 6 degrees in one second, it will take it:
294/6 = 49 seconds to move from halfway between 1 and 2 to 4/5 of the way from 1 to 2.
