Given:
The graph of a number line.
To find:
The set of values for the given number line.
Solution:
As we move from right to left on a number line the values decreased however as we move from left to right on a number line the values increased.
From the given number line it is clear that there is an open circle at 7 and a close circle at 10. It means 7 is not included in the solution set but 10 is included in the solution set.
From the point 7, the arrow approaching to the left it means all the values less than 7 are included in the solution set, i.e., x < 7.
From the point 10, the arrow approaching to the right it means all the values greater than 10 or equal to 10 are included in the solution set, i.e., x ≥ 10.
Solution set : x < 7 or x ≥ 10.
Therefore, the correct option is A.
Option D:
Measure of arc BEC = 228°
Solution:
Given angle A = 114° and vertical angle of A = 0.
<em>If two chords intersect inside the circle, then the measure of each angle is one half of the sum of the measures of the arcs intercepted by the angle and its vertical angle.</em>
Multiply by 2 on both sides, we get
Measure of arc BEC = 228°
Option D is the correct answer.
Answer:
32.9 inches
Step-by-step explanation:
this can be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base = 49
c = hypotenuse = diagonal = 59
l² + 49² = 59²
l² = 59² - 49²
3481 - 2401 = 1080
find the square root
32.9 in
Answer:
Yes because of the way the it is.
Step-by-step explanation:
A triangle ABC is similar to a triangle A´B´C´ The scale factor of the dilatation : s.
0 * s =0
4 * s = 10
6 * s = 15
s= 10/4=15/6=2.5
The scale factor of the dilatation is 2.5. It is shown in the attachment.
