Answer:
Not quite in proof format but here's a short explaination. You should be able to fill out the table yourself.
It is given that <T=<Y and <V+<U=180 degrees
<T=<Y are corresponding angles. Corresponding angles are congruent when the two lines (that the third line crosses to make a transversal) are parallel. So, l1 and l2 are parallel.
<V+<U are supplementary angles. They are same side interior angles. Same side interior angles are supplementary when two lines of the transversal are parallel (basically same thing as above, just different type of angle). So, l3 and l4 are parallel.
<R=<U because they are alternate interior angles. Alternate interior angles are congruent when the two lines are parallel (you have proved that l3 and l4 are parallel above).
<P=<C because they are alternate exterior angles. Alternate exterior angles are congruent when the two lines are parellel (you have proved that l1 and l2 are parallel above).

How does the graph of g(x) = −(x + 3)4 compare to the parent function of f(x) = x4?
A. g(x) is shifted 3 units to the right and 1 unit up.
B. g(x) is shifted 3 units to the right and 1 unit down.
C. g(x) is shifted 3 units to the right and reflected over the x-axis.
D. g(x) is shifted 3 units to the left and reflected over the x-axis.
Answers
The difference between the functions f(x) and g(x) is the addition of a
constant to the value of x and changing
the sign of the output.
The graph of g(x) compared to f(x) is g(x) is shifted 3 units to the left and
reflected over the x-axis.
Reason:
The addition of a positive constant term to the input variable of a function,
shifts the graph to the left of the graph of
the parent function.
Please find attached the image of the graph of f(x), which is g(x) shifted to
the left by 3 units.
Step-by-step explanation:
Changing the sign of the output value from positive to negative;
When the output value of a function is changed from positive to negative,
and vice versa, it is equivalent to a reflection across the x-axis.
Therefore, the function g(x) is a reflection across the x-axis.
Therefore;
g(x) is shifted 3 units to the left and
reflected over the x-axis.

1.
Since ABCD is a rectangle, then
angleABE = 90 degrees
angle ABE + angle BEA + 41 = 180
Substitute the known and solve for angle BEA
angle BEA + 41 = 90
angle BEA = 49 degrees
But,
x + angleBEA + 61 = 180 (angles in a straight line)
x = 180 - 61 - 49
x = 70 degrees
2.
triangle XYZ is equilateral, meaning all angles in it are the same, each 60 degrees.
Therefore,
Angle YZX = 60
But Angle YZX = x + 32 (exterior angles equal to the sum of the two opposite interior angles)
60 = x + 32
Therefore,
x = 28 degrees
3.
Angle QPR = Angle QRP (equal oppo sides, equal opposite angles)
Therefore, 2angleQRP + 64 = 180 (angle sum of a triangle)
Angle QRP = 58 degrees
But angle QRP = x + 35 (exterior angles equal to the sum of the two opposite interior angles)
58 = x + 35
x = 23 degrees
Answer:
See below:
Step-by-step explanation:
For the first one, we know <ABC is 90 degrees due to it being a rectangle.
Since we know that, the angles in that triangle are 41 degrees 90 degrees and y degrees (y is <AEB) in this case.
We know that the sum of angles in a triangle are 180 degrees therefore:
If we solve that, we get that y is 49 degrees.
Now to get x, we know its a supplementary angle, therefore 61 degrees + 49 degrees + x = 180 degrees.
We now know that x is 70 degrees
For the second one, since its an equilateral triangle, we know that all angles inside of it are 60 degrees.
What we can do is first find what <XZW is by subtracting 60 from 180 due to the supplementary angles theorum.
Therefore <XZW is 120 degrees.
Now, all angles inside a triangle are always 180 degrees so therefore:
[tex]x=180-(120+32)\\x=28[/tex]
For the final one, we know that <QRP is equal to 64 degrees due to the bottom two triangles of an isoceles triangle being equal.
On that, we get 23 degrees for the last one due to supplementary angles + 180 deg in triangle.

26/18 = 39/x
x = 39(18/26)
x = 27
could also use
39/x = (39 + 26) / (x + 18)
to get to the same result
39(x + 18) = x(39 + 26)
39x + 702 = 39x + 26x
702 = 26x
x = 27
or
18/x = 26/39
x = 18(39/26)
x = 27

Answer:
tan(A) = 7/24sin(A) = 7/25cos(A) = 24/25Step-by-step explanation:
The mnemonic SOH CAH TOA can help you remember the trig ratios:
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
With respect to angle A, the sides are Adjacent = 24; Opposite = 7, Hypotenuse = 25. Then the desired trig ratios are ...
tan(A) = 7/24
sin(A) = 7/25
cos(A) = 24/25
find the quotient of [tex]\frac{(x^{3} - 2x^{2} + 6x + 3)}{ (x - 3)}[/tex] using long division
Answers
(x^3 - 2x^2 + 6x + 3)/(x-3)
= (x^3 - 3x^2 + (x^2 - 6x + 9)+ 12x - 6)/(x-3)
= (x^2(x-3) + (x-3)^2 + 6(2x - 1))/x-3
= x^2 + x - 3 + 6(2x - 1)/(x-3)
or
= x^2 + x - 3 remainder 12x - 6
or, in the form p(x) = q(x)d(x) + r(x):
(x^3 - 2x^2 + 6x + 3) = (x^2 + x - 3)(x - 3) + (12x - 6)
which implies that the quotient q(x) = (x^2 + x - 3) and remainder r(x) = 12x - 6
What is 21 divided by 654
Answers
Answer:
Well your saying division but it looks like square root when you make the sharp edge there but I will answer the division one
so 21 goes into 65 3 times maximum
so 21*3 is 63
so we subtract 63 and put a 3 on top
so eventually you’d get 31.142857 (never ending decimal)
So you can convert into a fraction, at this rate I’d just put it in a calcualtor and it‘ll do it for you
so 31 1/7 is the final answer

B. 44 feet per minute
C. -12 feet

minute
D. -48 feet per minute
Answers
Answer:
C. -12 feet per minute
Step-by-step explanation:
This question is really just asking for the slope of this situation. So the best way to find the answer is to find the change in y over the change in x. In this case, y is the depth and x is the time. So, it would be -48/4 because the diver went down 48 feet when 4 minutes passed. Then, simply divide, -48/4, which equals -12 feet/1 minute.
