A point K is on the perpendicular bisector of a segment with endpoints at H and J. What must be true about point K? It is equidi

kykrilka [37]

Answer:

$K$ is equidistant from $H$ and $J$ .

Step-by-step explanation:

Given that the point $K$ which is on the perpendicular bisector of the line segment having endpoints at $H$ and $J$ .

The given situation can be represented as the diagram as attached in the answer area.

Referring to the $\triangle HOK, \triangle JOK$ :

$\angle HOK = \angle JOK=90^\circ$ (As it is the perpendicular bisector)

$OH = OJ$ (As it is the perpendicular bisector)

Also, the side $OK$ is the common side.

Therefore by $S-A-S$ congruence, $\triangle HKO\cong \triangle JKO$

As per the properties of congruent triangles:

Side $HK$ = Side $JK$

$HK$ and $JK$ are nothing but the distance of the point $K$ from the end points $H$ and $J$ which are proved to be equal to each other.

Therefore, we can conclude that:

$K$ is equidistant from $H$ and $J$ .

Deposits of $200 per month are put into an investment plan that pays an APR of 6.5%. How much money will be in the plan after

Cerrena [4.2K]

Answer:

The money will be $7455.97.

Step-by-step explanation:

Given : Deposits of $200 per month are put into an investment plan that pays an APR of 6.5%.

To find : How much money will be in the plan after 18 years ?

Solution :

There is a deposit of $200 per month.

For 1 year the principle value is $P=200\times 12=2400$

The rate of interest is r=6.5%=0.065

The time is t=18 years

Apply compound interest formula,

$A=P(1+r)^t$

$A=2400(1+0.065)^{18}$

$A=2400(1.065)^{18}$

$A=2400\times 3.1066$

$A=7455.97$

Therefore, The money will be $7455.97.

If the hypotenuse is c=a√2, then 6=a√2. In inches, what is the value of a?

Aloiza [94]

The value of a is 3√2 inches if it is given that the hypotenuse is c = a√2 and 6 = a√2. This can be obtained by using Pythagoras' theorem.

<h3>Calculate the value of a:</h3>

This question can be solved using Pythagoras' theorem,

If in a right angled triangle, hypotenuse is the longest side of the triangle and always opposite to the angle 90°, height and base are the two shorter sides which are adjacent to the angle 90°.

If hypotenuse = c, height = a and base = b then,

⇒ hypotenuse² = height² + base²

⇒ c² = a² + b²

Here in the question it is given that,

Hypotenuse of the triangle is c = a√2
6 = a√2 in inches ⇒ c = 6

Height and base is equal and both has the value of a ⇒ height = a and base = a

By using the Pythagoras' theorem we can write that,

⇒ hypotenuse² = height² + base²

⇒ 6² = a² + a²

⇒ 36 = 2a²

By dividing both sides of the equation by 2,

⇒ 18 = a²

⇒ a² = 18

By taking square on both side of the equation,

⇒ a = 3√2 inches

Hence the value of a is 3√2 inches if it is given that the hypotenuse is c = a√2 and 6 = a√2.
