If X= 9 and Y = 3, what is XY

Answer:

1.5 < 3 - √2 < 1.6

Step-by-step explanation:

Loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.

When energy moves through a medium (such as air, water, or any other liquid or solid matter), it creates a pattern of disturbance known as a sound wave that propagates away from the sound source.

When an object vibrates, sound waves are produced that are similar to pressure waves, like when a phone rings.

Pitch, intensity, and timbre are three key components of the field of sound psychology or psychoacoustics. People can distinguish the harmonics of a complex periodic sound wave under certain conditions thanks to the way that humans perceive sound and music.

Thus, loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.

Answer: A: (6, 5)

Step-by-step explanation:

When graphing a system of equations, you can find the solution by finding where the graphs intersect. In this case, the graphs intersect at (6, 5).

To verify that this is indeed a solution to the system of equations, we can substitute (6, 5) into both of the given equations:

\(y = \frac{1}{2}x + 2\)

\(5 = \frac{1}{2} * 6 + 2\)

\(5 = 3 + 2\)

\(5 = 5\)

\(y = x - 1\)

\(5 = 6 - 1\)

\(5 = 5\)

Since both equations hold true when plugging in the given coordinate (6, 5), we know that this is a solution to the system of equations.

Maraging (18% Ni) steel has a better tolerance to defects and fracture toughness compared to Medium strength steel.

The tolerance to defects and fracture toughness of a material can be evaluated using its fracture toughness parameter, Kic. The higher the Kic value, the better the material's tolerance to defects and fracture toughness.

To compare the two materials, we can use the concept of critical stress intensity factor (Kic) and factor of safety (FoS). The critical stress intensity factor is the maximum value of stress intensity factor (K) that a material can withstand without fracturing. The factor of safety is the ratio of the maximum allowable stress to the design stress, and it is used to ensure a safety margin in the design.

Assuming that the two materials have the same defect to tolerance ratio, we can calculate the maximum allowable stress for each material using the following formula:

σmax = FoS * Kic / (π * a)

where σmax is the maximum allowable stress, FoS is the factor of safety (assumed to be 2), Kic is the fracture toughness parameter, and a is the size of the defect.

Let's assume a defect size of 1 mm for both materials. Using the values given in the question, we get:

For Maraging (18% Ni) steel:

σmax = 2 * 82 * 10^6 / (π * 1 * 10^-3) = 52.1 GPa

For Medium strength steel:

σmax = 2 * 50 * 10^6 / (π * 1 * 10^-3) = 31.8 GPa

Therefore, Maraging steel has a higher maximum allowable stress, which indicates that it has a better tolerance to defects compared to medium strength steel.

To compare the fracture toughness of the two materials, we can use their respective Kic values. The higher Kic value indicates a better tolerance to defects and fracture toughness.

Comparing the given values, we can see that Maraging (18% Ni) steel has a higher fracture toughness parameter (Kic= 82 MNm-3/2) compared to Medium strength steel (Kic= 50 MNm-3/2).

Therefore, Maraging (18% Ni) steel has a better tolerance to defects and fracture toughness compared to Medium strength steel.

Step-by-step explanation:

the middle number wich is 500

The slope (m) of the MB is: 1. The equation of the line of MB is: y = x.

We can express the equation of a line in slope-intercept form as, y = mx + b, where we have:

Slope = m = change in y / change in x

y-intercept = b.

Given the points, M(-4,-4) and B(-1,-1), to find the equation that the points lie on, first, find the slope of MB:

Slope (m) = (-4 -(-1))/(-4 -(-1))

Slope (m) = -3/-3

Slope (m) = 1

Substitute (x, y) = (-1, -1) and m = 1 into y = mx + b to find b

-1 = 1(-1) + b

-1 = -1 + b

-1 + 1 = b

b = 0

Substitute m = 1 and b = 0 into y = mx + b

y = 1(x) + 0

y = x.

Thus, the slope (m) of the MB is: 1. The equation of the line of MB is: y = x.

Check the picture below.

so the height we're looking for is "h" as you see in the picture on the far right.

first off, let's take a look at the left side of it, we have a circle with a radius of 15, now plugging that into the area of a circle to get its area, πr² gives us π15² or just 225π, that's the whole area of the circle, let's now get the area of the sector with 144° and subtract it from it, and what we'll  be left with, will just be the blue part, the 216° sector area.

\(\textit{area of a sector of a circle}\\\\ A=\cfrac{r^2\theta \pi }{360}~~ \begin{cases} r=radius\\ \theta =\stackrel{in~degrees}{angle}\\[-0.5em] \hrulefill\\ r=15\\ \theta =144 \end{cases}\implies A=\cfrac{15^2(144)\pi }{360}\implies A=90\pi \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{area of the whole circle}}{225\pi }-\stackrel{\textit{area of the }144^o~sector}{90\pi }\implies \stackrel{\textit{area of the cone uses}}{135\pi }\)

now, let's take a peek a the picture in the center, as we get the blue edges together from the material to form the cone, the slant-height becomes the 15 value from the radius of the circle making the cone, so our cone's slant-height is 15 then.

now, the cone is open at the top, so area wise, the only area used by the cone is the blue section, namely what we already know is 135π, oddly enough, that's the lateral area of the cone, so let's use our slant-height and lateral area of it to get the radius of the cone, let me use a "R" for this radius, to separate it from the one from the circle.

\(\textit{lateral area of a cone}\\\\ LA=\pi R\sqrt{R^2+h^2}~~ \begin{cases} LA&=135\pi \\ \sqrt{R^2+h^2}&=15 \end{cases}\implies 135\pi =\pi R15 \\\\\\ \cfrac{135\pi }{15\pi }=R\implies 9=R\)

now, we know the cone has a radius of 9 and we also know its's slant-height, as you can see in the far right of the picture, we can just use pythagorean theorem to get "h".

\(15^2=h^2+9^2\implies 15^2-9^2=h^2\implies \sqrt{225-81}=h\implies \blacktriangleright 12=h \blacktriangleleft\)

The equation of the line in slope-intercept form is y = (3/4)x.

To write the equation of a line in slope-intercept form, we need to use the slope-intercept form equation: y = mx + b,

where m is the slope and b is the y-intercept.

Given that the line passes through the point (-8, 5) and has a slope of 3/4, we can substitute the values into the equation to find the y-intercept (b).

First, let's find the value of b using the point-slope form equation: y - y1 = m(x - x1), where (x1, y1) is a point on the line.

Using (-8, 5) as the point and 3/4 as the slope, we have:

5 - 5 = (3/4)(-8 - x)

0 = (3/4)(-8 - x)

0 = (-3/4)(8 + x)

0 = -6 - (3/4)x

Next, we can solve for x:

(3/4)x = -6

x = -6 \(\times\) (4/3)

x = -8

Now that we have the value of x, we can substitute it back into the equation to find the value of b:

0 = -6 - (3/4)(-8)

0 = -6 + 6

0 = 0

So, the value of b is 0.

Finally, we can write the equation of the line in slope-intercept form:

y = (3/4)x + 0

y = (3/4)x.

Answer:

8 = 34 + (n * 2) / 8 = (n * 2) + 34 ; n = -13

Step-by-step explanation:

In this question we have 2 numbers and a variable. The variable is "a number," which I have represented as "n" in my answer. As long as there is a letter in the spot of n, that is the correct answer- your assignment might have represented the variable differently.

When the question says "8 is" it is saying "8 is equal to." "Is" represents an equals sign in this equation. "More than" represents addition, or the sum of. "The product of" represents multiplication. "The product of a number and 2" means that we are multiplying n and 2 BEFORE adding it to 34, so we want to make sure to include those in parenthesis to signify that we do indeed solve that part of the equation first. As long as you know PEMDAS you should be fine here, but I prefer to add what the equation wants me to do first in parenthesis so that it's more readable. Since the order of numbers doesn't matter in addition, 34 can go both before and after "the product of n and 2."  

This gives us the equation "8 = 34 + (n * 2)," or the alternate "8 = (n * 2) + 34."

If you want to solve for N, you would need to subtract 34 from 8 and 34 itself, leaving -26 = (n * 2) or -26 = n(2). Then, since we're multiplying n by 2, we want to divide 2 by 2 to cancel it out, doing the same thing to -26. We are left with -13 = n, or n = -13.
