Answer:

Firstly, from the diagram we are given that the length of XB is congruent to BZ, and YC is congruent to CZ. Based on this information, we know that B is the midpoint of XZ, and C is the midpoint of YZ. This means that BC connects the midpoints of segments XZ and YZ. Now that we know this, we can use the Triangle Midsegment Theorem to calculate the length of BC. This theorem states that if a segment connects the midpoints of two sides of a triangle, then the segment is equal to one-half the length of the third side. In this scenario, the third side would be XY, which has a length of 12 units. Therefore, the length of BC = 1/2(XY), and we can substitute the value of XY and solve this equation:

BC = 1/2(XY)

BC = 1/2(12)

BC = 6

Un industrial obtiene un préstamo de $ 15.000, al 23% anual por el lapso de 5 años. Calcular el monto a la finalización de este

olasank [31]

Answer:

$18,781.5

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Loan amount (P) = $15,000

Rate of interest (r) = 23%

Time (t) = 5 years

Let this loan is compounding annually, then the amount after 5 years can be calculated as follows,

Final amount = P $(1 + ( r/t))^{t}$

by putting the value in formula, we get

= $15,000 ( $(1 + ( 0.23/5))^{5}$

= $15,000 × 1.2521

= $18,781.5

Use the properties of logarithms to rewrite each expression in an equivalent form containing a single logarithm.

Shalnov [3]

Answer:

log(5/4)

Step-by-step explanation:

You have to apply the properties of logarithms to the given expression in order to obtain a form with a single logarithm.

For example, the quotient rule:

$log(\frac{x}{y}) = log(x) - log (y)$

In this case, log(x) = log (5/6 ) and log(y)= log (2/3)

Therefore x = 5/6 and y = 2/3

Applying the rule:

log (5/6 )− log (2/3) = $log(\frac{5/6}{2/3})$

Solving the argument of the logarithm (The division of the fractions)

$\frac{5/6}{2/3} = \frac{(5)(3)}{(6)(2)} =\frac{15}{12} =\frac{5}{4}$

The equivalent form is:

log(5/4)
