Comparing the √17 and 29/7 using <, > or = , we have √17 < 29/7.
Define comparing.Mathematical number comparison is the process or method of comparing two numbers to determine whether one is less, bigger, or equal to the other. The comparison symbols for numbers are "=", which stands for "equal to," "=", which stands for "greater than," and " ", which stands for "less than." Comparing amounts is a technique for figuring out how much to compare units in relation to a different standard or reference unit. A common reference point is necessary for two comparing units to be compared; otherwise, they cannot be compared.
Given,
Comparing the following using <, > or = ,
Numbers:
√17 and 29/7
For √17
Simplifying,
√17 = 4.123
For 29/7
29/7 = 4.14

Find m

The angle measurement of T is 80°.
What is an angle measurement?When two lines or rays intersect at a common point, an angle is formed. The common point is referred to as the vertex. An angle measure in geometry is the measurement of the angle formed by two rays or arms at a common vertex.Here given,
∠Q = (9x - 17)°
∠R = (4x + 28)°
Since ∠Q and ∠R are co-interior angles in parallel lines.
∠Q + ∠R = 180°
So,
(9x - 17) + (4x + 28) = 180°
= 9x - 17 + 4x + 28 = 180°
By adding x variables together,
13x + 11 = 180°
=> 13x = 180°-11
=> x = 169° ÷ 13
x = 13
By substituting x,
∠Q = 9 x 13 - 17
= 117 - 17
= 100°
∠Q + ∠T = 180° (angles on a straight line is 180°)
100 + ∠T = 180°
∠T = 180 - 100
∠T = 80°
Therefore the value of ∠T is 80°.

cos (x + 16) = sin(3x – 2)
Answer:
x = 19
Step-by-step explanation:
So cos and sin are closely related, but they are not equal. In order for these two to be equal to each other, the angles (in the parenthesis by the cos and by the sin) have to be complementary. That is, they have to add up to 90°
Use this idea to set up an equation.
x + 16 + 3x - 2 = 90
Combine like terms.
4x + 14 = 90
Subtract 14.
4x = 76
Divide by 4.
x = 19
x = 19
If you are kooking for the angles:
x + 16
= 19 + 16
= 35
and
3x - 2
= 3(19) - 2
= 57 - 2
= 55
Check: 35 + 55=90
Also,
cos35 = sin55
The y-intercept of the function f(x) = :
2/3[x| + 4 is (0,4). If the
function is translated down 9 units, what will be the new y-intercept?
The new y-intercept of the function is (0. -5)
How to determine the new y-intercept?From the question, we have the following parameters that can be used in our computation:
f(x) = 2/3|x + 4}
y-intercept = (0. 4)
The function is translated by
9 units down
This is represented as
(x, y) = (x, y - 9)
Substitute the known values in the above equation, so, we have the following representation
New y-intercept = (0. 4 - 9)
Evaluate
New y-intercept = (0. -5)
Hence, the new y-intercept = (0. -5)

Step-by-step explanation:
Graph a triangle ABC and perform a translation of (x + 4, y - 3) to create triangle A'B'C'.
1. Describe the transformation using words. Make sure you refer to the characteristics
and the coordinates.
2. Draw a line through points A and A' and through points B and B'. What do you
notice about the lines you drew? Do you think you would notice the same
characteristics if you drew another line through points C and C'? How do you know?
1. The translation was of 4 units right and 3 units down.
2. All the blue lines connecting the equivalent vertices will have a slope of -3/4.
What is the translation?
The translations of the triangle is given by the rule presented as follows:
(x,y) -> (x + 4, y - 3).
Hence the meaning of each of these translations is given as follows:
x -> x + 4 is a translation of four units right.y -> y - 3 is a translation of three units down.The coordinates of the original vertices are given as follows:
(0,0), (0,4), (3,0).
Then the coordinates of the translated vertices are given as follows:
(4,-3), (4,1), (7,-3).
For a linear function, the slope is given by the vertical change divided by the horizontal change.
From these translations, the changes are given as follows:
Vertical change of 3 units down, hence of -3.Horizontal change of 4 units right, hence of +4.Thus the slope of the linear function connecting the original vertices are given as follows:
m = -3/4.

What is the slope of the line that passes through the points (6, -5) and (−6,−5)?
Slope of the line having passing points (6,-5) and (-6,-5) is 0.
What do you mean by slope of the line?
A line's slope is defined as the ratio of the change in y coordinate to the change in x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Hence, the change in y-coordinate with regard to the change in x-coordinate is given by,
m = change in y/change in x
Given passing points :
(6,-5) and (-6,-5)
Slope of the line having passing points (x,y) and (a,b) is given by [tex]\frac{b-y}{a-x}[/tex]

Which table shows a proportional relationship between x and y?
We can consider that table (A) shows a proportional relationship of 7/1.
What is the proportional relationship?Relationships between two variables that are proportional occur when their ratios are equal.
Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value.
The "constant of proportionality" is the name of this constant.
So, consider the tables as follows:
Table A:
7/1
14/2 = 7/1
28/4 = 7/1
35/5 = 7/1
Proportional relationship: 7/1
Now, we don't need to calculate further.
Therefore, we can consider that table (A) shows a proportional relationship of 7/1.

Answer:
It is not possible to determine the dimensions of a rectangle with only the information that its area is 2/9. The area of a rectangle is calculated by multiplying its length by its width, so a rectangle with an area of 2/9 could have many different combinations of length and width. For example, a rectangle with dimensions of 1/3 by 2/3 would have an area of 2/9, as would a rectangle with dimensions of 2/9 by 1.
