the angle of the tower would be the coifficent
Answer:
a) The location of the turning point is approximately 
.
b) Roots are approximately 
and 
.
c) 
Step-by-step explanation:
a) The figure presents the graphic of a parabola, that is, a second order polynomial, with an absolute minimum (vertex). The turning point of the graphic, that is, the point in which behavior of the curve changes, is the vertex. Hence, the location of the turning point is approximately
b) According to the Quadratic Formula, second-order polynomials can have either two real roots or two conjugated complex roots. In this case, we have two real roots. A root corresponds with the point of the curve that passes through x-axis. In this case, roots are approximately and .
c) 
is the function evaluated at 
, that is, the value on y-axis associated with . Lastly, we conclude that .
First picture:
When two lines intersect, they form 4 angles. Each 2 vertically opposed angles, are equal.
The sum of 2 angles is 114. We suppose they are vertically opposed, which means that each angle is 114/2 = 57 degrees.
Now the 4 angles of 2 intersect lines form a 360 degrees angle. Which means that the sum of the 2 other angles is 360 - 114 = 246 degrees.
Same thing, we divide that angle in 2 and we get 246/2 = 123. Which means that the other 2 angles are 123 degrees each.
So the sum of all the angles are 57, 57, 123 and 123.
Second Picture:
By hypothesis, we know that the angle is 172 degrees. The angle bisector divides an angle in 2 equal angles. So both angles, in this case, will be 172/2 = 86 degrees.
So the measure of an angle formed by the angle bisector of a given angle (172 degrees) and one of its sides is, in this case, 86 degrees.
Hope this helps! :)
Answer:
Step-by-step explanation:
Domain of a function is given by the set of x-values (Input values) on the graph.
Range of a function is given by the set of y-values (output values) on the graph.
From the graph attached,
Set of time will represent the "domain" and set of snowfall will represent the "range" of the function graphed.
a). Domain of the function: 0 ≤ x ≤ 5
b). Range of the function: 0 ≤ y ≤ 10
Mg, Ai, Si, P. This is the correct answer!
