Here are the answers to the given questions above:
4. When we say pythagorean triple, this would consists of three positive integers a, b, and c, such that a2 + b2 = c2. So for the given numbers above, the set that is considered a pythagorean triple would be B.  8, 15, 17.
5. The correct answer for this question would be option D. It cannot be determined whether the triangle is obtuse, acute or right if the given values are the side lengths. It should be angles. Hope this answer helps.

A triangle has side lengths measuring 3x cm, 7x cm, and h cm. Which expression describes the possible values of h, in cm? 4x < h < 10x 10x < h < 4x h = 4x h = 10x

Answer with explanation:

In a triangle sum of two sides , should always be greater than the third side.

Sides of the given triangle are, 3 x cm, 7 x cm and h cm.

1.

3 x + 7 x > h

→ 10 x > h

2.

3 x+ h > 7 x

→h > 7 x -3 x

→h> 4 x

3.

7 x + h > 3 x, which will be always true.

Combining 1, 2 and 3 we get

→4 x < h < 10 x

Option A

Which of the following statements is true of a reflection? -It is an isometry. -It slides a plane. -The transformation is done over a line of reflection. -It flips a plane about a fixed line. I-t changes the size of the figure being reflected.

I think the correct answers from the choices listed above are the first and the fourth option. The statements that are true about a reflection would be that it  is an isometry and the it flips a plane about a fixed line. reflection over a line k (notation rk) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from line k.

Which of the following is the statement of the triangle inequality theorem? A. The sum of the measures of any two angles of a triangle is greater than the measure of the third angle. B. The sum of the lengths of any two sides of a triangle is greater than the length of the third side. C. The longest side of a triangle is opposite the largest angle. D. The largest angle of a triangle is between the two longest sides.

we know that

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

so

Let

a,b,c------> the length sides of a triangle

The theorem states that three conditions must be met

case 1)

 a+b > c

case 2)

 a+c > b

case3)

 c+b > a

therefore

the answer is the option

B. The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Calculate the moments Mx, My, and the center of mass (x bar, y bar) of a lamina with the given density p=5 and the shape:

M x = 1/2 p ∫ ( f ( x )² - g ( x )² ) d x
f ( x ) = √( 1 - x²),  g ( x ) = - 2
M x = 1/2 * 5  \int\limits^1_{-1} (- x^{2} -3)\, dx= \\ =-5/2 * [ x^{3}/3 + 3 x]^1 _{-1} = \\ =-5/2 * (1/3+3+1/3+3)=
= - 50/3
My = p ∫ x * ( f ( x ) ) dx
My = p ∫ x ( √(1+x²)) dx
Substitution: 1 - x² = u,  x dx = - du/2
M y = 5 *  \int\limits^0_0 { \sqrt{u} } \, du = 0
M x = - 50/3, M y = 0
M = 5 *  \int\limits^1_{-1}  { (\sqrt{1+ x^{2} }+2)} \, dx  = \\ &#10;=5* [1/2  \sqrt{1+ x^{2} }  *x + 2 x + 1/2 *sinh ^{-1} x]^1_{-1}
M ≈ 5 * 6.3 ≈ 31.2  
x = M y / M = 0 / 31.5 = 0
y = M x / M =  -50/3 : 31.5 ≈ - 0.529
The center of mass is ( 0, -0.529 )

Which answer describes the type of sequence? −99, −88, −66, −55, ... A. arithmetic B. neither arithmetic nor geometric C. geometric

Here, Geometric ratio, r = -88/-99 or -66/-88 which is 8/9 or 6/8. As they are not equal, it is not a geometric.

Now, Arithmetic difference, d = -88-(-99) or -66-(-88) which is 11 or 22. As they are not equal, it is not a Arithmetic.

So, it's neither an Arithmetic nor a Geometric.

Option B is your answer!

Hope this helps!

NEEDED ASAP PLEASE A relation is plotted as a linear function on the coordinate plane starting at point C (0,−1)(0,−1) and ending at point D (2,−11)(2,−11) . What is the rate of change for the linear function and what is its initial value? Select from the drop-down menus to correctly complete the statements.The rate of change is -11, -5, 0, 5.and the initial value is -11, -2, -1, 0.

The rate of change for your linear function is the slope.  You can use the points C and D to calculate it. 
slope = (y2 - y1)/(x2 - x1) = (-11 - (-1))/(2 - 0) = -10/2 = -5
I'm not sure what is meant by initial value, but maybe you are looking for the y-intercept of the line.

The y-intercept is the point where the line crosses the y axis, so where x = 0.  You have that because your line passes through the point (0, -1).  When x = 0, y = -1.

Find the volume of the composite figure ( also I'm not going to redo this question becuase, u should be able to zoom in) Ok, please help me answer 1-6 DUE ON MONDAY! Also I have to do the review!

I can answer only from 1 to 4 since idk how to do number 5 and the picture is missing part of number 6.
1) would be 12 since the bottom block would be 4*2*1 (8) and then 2*2*1 would be 4. 4+8= 12 cubic inch.

2) You did it correctly!

3) 6*3*1=18 and 7*1*3=21 21+18 is 39 cubic inch.

4) 6*4*12= 288 and 8*4*4= 128 128+288= 416 cubic ft
I am like 98% I did it correctly but sometimes I have a mistake so... yeah hope it helps!

How to find the orthocenter of an obtuse triangle

Find the equations of 2 segments of the triangle Once you have the equations from step #1, you can locate the slope of the corresponding perpendicular lines.You will use the slopes you have found from step #2, and the corresponding opposite vertex to find the equations of the two lines.Once you have the equation of the two lines from step #3, you can solve the corresponding x and y, which is the coordinates of the orthocenter.

The population of Cambridge, Massachusetts, is 101,355. The population of Boston is 616,535. What is the population of the two cities altogether? Hana solved this problem. She said that the answer was 717,890. Which statement is correct?

Hana's statement is indeed the correct one. How I determined this answer:

The question asks you for the total populations of Cambridge, Massachusetts, and Boston, Massachusetts, altogether. That means you have to add the two given numbers together: 616,535 + 101,355 = 717,890. This, of course, is also what Hana did and got for the answer, therefore her statement is the correct one.

Hope I helped you! :)
