3y-12=-30
3y=-30+12
3y=-18
y=-18/3
y=-6.
Answer: A.
352 . If you multiply 16 by 22 it will give u an answer of 352
Answer:
x= 1
Step-by-step explanation:
x = 1 is the axis of symmetric for the graph
if we draw a line parallel to the y axis one units to the right side of the origin we get the line of symmetry of the graph.
and since the line of symmetry is parallel to y axis and passes thru the point (1, 0) it's equation is x= 1
Answer:
<h2>11.72cm</h2>
Step-by-step explanation:
Given a chord of distance of 15cm, if it is 9cm from the center of a circle, this means that the 9cm length will be projecting from the centre of the circle perpendicular to the chord and passing through its centre.
Since the radius of a circle is a line that is drawn from the centre of a circle to ts circumference, the set up will form a right angles triangle within the circle with the hypotenuse as the radius and the other two sides as the opposite and adjacent respectively. Using the Pythagoras theorem to get the length of the radius (hypotenuse);
hyp² = opp² + adj²
Let the opposite be the 9cm length
Adjacent will be half of the chord length = 15/2 = 7.5cm
Substituting this values into the formula we will have;
hyp² = 9² + 7.5²
hyp² = 81+56.25
hyp² = 137.25
hyp² = √137.25
hyp = 11.72
<em></em>
<em>Hence the radius of the circle is approximately 11.72 cm long</em>
If I am correctly understanding the question, I think the length of the line segment would be 4AB
Step-by-step explanation:
25% = 1/4
AB = 1/4
100% = 4/4
AB*4 = 4AB
Multiply AB by 4 to find the value that 100% would equal, resulting in 4AB.
