If two chords intersect each other inside a circle, the products of their segments are equal.
If M is midpoint of AB, then AM = MB = 24/2 = 12.
<span>Product of the lengths of the segments AM and MB:
</span>AM * MB = 12 * 12 = 144
<span>So, any chord of circle O that intersects AB at its midpoint, M, wll be separated by M into two segments such that the product of the lengths of the segments is 144.

Answer:
A is spanned by vector.
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
Answer:
1 7/10 or 1.70
Step-by-step explanation:
6 1/2 - 9/10
Convert the mixed number to an improper fraction
13/2 - 9/10
Find a common denominator for these 2 fractions, and in this case it can be 10
13 * 2/ 5 * 2
26 / 10 - 9/10
17/10
1 7/10 as a fraction or 1.70 as a decimal
Hope this helped!

Answer:
69090840 possible rankings
Step-by-step explanation:
The number of possible ranking ordered in terms of effectiveness can be obtained using permutation
Number of salesperson = 39
Number of rank = 5
nPr = n! ÷ (n - r)!
nPr = 39P5
39P5 = 39! ÷ (39 - 5)!
39P5 = 39! ÷ 34!
39P5 = 39 * 38 * 37 * 36 * 35 = 69090840
Answer:
Angle L is a base angle and measures 72°.
Step-by-step explanation:
Triangle JKL is isosceles.
The measure of angle J is 72°
The measure of angle K is 36°
Angles in a trinagle add up to 180° so angle L is;
180° - (36° + 72°) = 72°
An isosceles triangle means that two of its sides are equal and two base angles are equal. So base angles are angles J and L and measures 72° each.
