Answer:
∠ D2 = 16°
Step-by-step explanation:
complementary angles sum to 90° , then
∠ D1 + ∠ D2 = 90°
74° + ∠ D2 = 90° ( subtract 74° from both sides )
∠ D2 = 16°
If two angles are complementary they add up to a total of 90 degrees.
So we know that
D1+D2=90, because the problem tells us they're complementary
Now, we know as well that D1 = 74, so we can plug it into the little equation and solve in terms of D2.
[tex]D1+D2=90[/tex]
[tex]74+D2=90[/tex]
[tex]D2=90-74[/tex]
[tex]D2=16[/tex]

Find the y-intercept of the line on the graph
Since no equation of the line, or graph is provided in the question statement, considering the line to be [3x +4y = 12], the y-intercept of the line is 3.
As per question statement, we are supposed to determine the y-intercept of the line on the graph, but no equation of the line, or graph is provided. Hence, we considered the equation of a random line, say,
[3x +4y = 12] and then, determine it's y-intercept.
To solve this question, we can use two methods:
One method is by converting the given equation into the format of the standard equation of a line, and then comparing it to the standard equation to determine the y-intercept, i.e.,
The standard equation of line is (y = mx + c), where, "m" is the slope of the line, and "c" is the y-intercept. Converting [3x +4y = 12] to the form of the standard equation, we get,
[tex]3x+4y=12\\or,4y=-3x+12\\or,y=\frac{-3x+12}{4}\\ or,[y=(\frac{-3}{4})x+3]...(i)[/tex]
Now comparing (i) to the standard equation of line, we can identify that
(c = 3), i.e., y-intercept of the line [3x +4y = 12] is 3.
Another way we can determine the y-intercept of a line is by, substituting (x = 0) and then solving the equation for "y".
Y-Intercept: The y-intercept is the point on a cartesian plane, where a graph crosses the y-axis, i.e., the value of y when (x = 0).To learn more about Y-Intercepts, click on the link below.

The table below shows the cost of gasoline based on the number of gallons purchased. Gallons Purchased Cost of Gasoline 5 $16.25 8 $26.00 11 $35.75 14 $45.50 Which equation represents the cost, y, of x gallons of gasoline? Responses
The equation that represents the cost, y, of x gallons of gasoline, is expressed as: y = 3.25x.
How to Create a Linear Equation for a Table?To create an equation in slope-intercept form, y = mx + b, for a table of values, use two pairs of values from the table to find the slope (m) and determine the y-intercept (b).
Using (5, 16.25) and (8, 26.00) find the slope (m):
Slope (m) = change in y / change in x = (26.00 - 16.25) / (8 - 5)
Slope (m) = (9.75) / (3)
Slope (m) = 3.25
Find the y-intercept (b) by substituting m = 3.25 and (8, 26.00) into y = mx + b:
26.00 = 3.25(8) + b
26.00 = 26.00 + b
26.00 - 26.00 = b
0 = b
b = 0
Substitute m = 3.25 and b = 0 into y = mx + b:
y = 3.25x + 0
y = 3.25x
Therefore, the equation that represents the cost, y, of x gallons of gasoline, is expressed as: y = 3.25x.

Part a: Expression for length; l = 2w + 3.
Part b: Perimeter equation; P = 2(l + 10).
Part c: Length of rectangle = 29 feet.
What is defined as the rectangle?A rectangle is a the kind of quadrilateral, a two-dimensional shape with four sides as well as four vertices. The rectangle's four angles are all right angles as well as equal to 90 degrees.The given conditions are-
Let 'l' be the length of the rectangle.
Let 'w' be the width of the rectangle.
Part a: expression for the length of a rectangle in the terms of w.
Length is three feet more than twice its width.
l = 2w + 3
Thus, the expression of l in terms of w is: l = 2w + 3.
Part b: Perimeter equation.
The width is given as 10 feet.
The formulae of perimeter if rectangle is;
P = 2(l + w)
Put the value;
P = 2(l + w)
P = 2(l + 10)
Thus, the equation for perimeter is P = 2(l + 10)
Part c: Length of rectangle.
perimeter of rectangle = 78 units.
P = 2(l + w)
w = 10 feet.
78 = 2(l + 10)
l + 10 = 39
l = 29
Thus, the length of the rectangle is found as 29 feet.

It should be noted that the first step makes the figures be the same by size but the second step, reflection over line AE doesn't map them together.
In this case, the correct line of reflection would be a vertical line through point D.

1. Dilate using center D and scale factor 2.
2. Reflect using the line AE.
2. Let f(x) = x4 + 2x3 - x² - 2x + 10. Given that one root of f(x) is 1 + i find all other roots.
All the roots of equation x⁴ +2x³ -x² -2x +10 are: (1 + i), (1 - i), -2i, 2i
In the given question, we have to find out all the roots or solutions for the equation x⁴ +2x³ -x² -2x +10. One of the roots given for this equation is 1+i
According to the 'Complex Conjugate' pairs, if an equation has a complex number as a root then its conjugate will also be a root of the equation.
So, we get z = 1 + i as a root then z* = 1 - i which is the conjugate of z, and z* will also be a root of the equation.
Also, the product of two roots will also be a root of the equation. So,
we know that, x = 1 + i, x = 1 - i, we get their product:
(x -(1 + i))*(x - (1 - i)) => by solving we get => x² -2x +2 = 0
=> x² -2x +1 = 1 => x² -x -x +1 = 1 (by middle term split)
=> x(x-1) -1(x-1) = 1 => we get (x - 1) as a factor
So, (x - 1) = 1 => x = 2
=> x = -2i, we get x = -2i
Again, by Complex conjugate pairs if x = -2i is a factor then it's conjugate x = 2i is also a factor.
Hence, the roots of the equation are: (1 + i), (1 - i), -2i, 2i

Maximum value occurs at the vertex, given by (h,k)=(-2,8)
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
The given function is: h(x) = -(x + 2)² +8.
This function is in the form: a[tex](x-h)^{2}[/tex]+k
Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object. The word symmetry implies balance.
The axis of symmetry is given by x = h
By comparison, we have -h=2.
This implies h=-2
Therefore the axis of symmetry is x = -2
The maximum value of a function is the place where a function reaches its highest point, or vertex, on a graph. If your quadratic equation has a negative term, it will also have a maximum value.
