Answer:
d)
Step-by-step explanation:
A polynomial is said to be in standard form if its terms are arranged in order of decreasing degree. That is the first term is of highest degree followed by the second term then the third term and so on. The terms of a standard polynomial are ordered from highest degree to lowest degree.
The polynomial is in standard form because the degree of x are arranged from highest degree to lowest degree.
Answer:
Step-by-step explanation:
In this problem, we have:
H = 452 m is the height of the Petronas tower
h = 1.75 m is the height of the woman
d = 120 m is the distance between the woman and the base of the tower
First of all, we notice that we want to find the angle of elevation between the woman's hat the top of the tower; this means that we have consider the difference between the height of the tower and the height of the woman, so
Now we notice that and are the two sides of a right triangle, in which the angle of elevation is . Therefore, we can write the following relationship:
since
H' represents the side of the triangle opposite to
d represents the side of the triangle adjacent to
Solving the equation for , we find the angle of elevation:

Answer:</h3>
- slope = 1/2
- equation: y = 1/2x +5
<h3>
Step-by-step explanation:</h3>
Slope
The slope of the line between two points (x1, y1) and (x2, y2) is ...
... m = (y2 -y1)/(x2 -x1)
For your given points, the slope is
... m = (4 -9)/(-2 -8) = -5/-10
... m = 1/2
Equation
The point-slope form of the equation for a line can be written ...
... y = m(x -h) +k . . . . for a line of slope m through point (h, k)
Using the first point given and the slope just calculated, the equation for the line can be written ...
... y = (1/2)(x -8) +9
... y = (1/2)x -4 +9 . . . . eliminate parentheses; next, collect terms
... y = 1/2x +5
