To answer the given problem above, first we must note that 1 kilometer is equal to 0.621371. So to convert 160 kilometers to miles, multiply it by 0.621371 so the product is 99.41936. Therefore, 160 kilometers is equal to 99.41936 miles. Rounding it off to the nearest tenth, then it is 99.42 miles.

Given: CD is a perpendicular bisector of AB . Prove: Any point on CD is equidistant from the endpoints of AB . Match each statem

Sunny_sXe [5.5K]

Answer:

The two triangles are congruent, so any point on CD will be equidistant from endpoints of AB.

Step-by-step explanation:

Let the consider the figure as per the attached image:

AB be a line whose perpendicular bisector line is CD.

CD divides the line AB in two equal line segments making an angle of $90^\circ$ on both the sides as shown in the attached figure.

Let a point on CD be E.

Here, two triangles are formed:

$\triangle AED\ and \ \triangle BED.$

Side ED is common between the two triangles.

Also, Side ED is perpendicular bisector:

$\angle EDA = \angle EDB =90^\circ$

And Sides AD = DB

According to SAS congruence (i.e. Two sides are equal and angle between them is equal):

$\triangle ADE \cong \triangle BDE$

And as per the <em>properties of congruent triangles, all the sides are equal.</em>

$\Rightarrow EA = EB$

EA and EB is the distance of point E on line CD from the endpoints of line AB.

Hence proved that Any point on CD is equidistant from the endpoints of AB .

Evaluate the function at each specified value of the independent variable and simplify. (if an answer is undefined, enter undefi

tekilochka [14]

For this case we have the following function:

$h (t) = t ^ 2 - 8t$

What we should do is evaluate the function for the different values of the independent variable.

We have then:

For x = 8:

$h (8) = (8) ^ 2 - 8 (8)$

$h (8) = 64 - 64$

$h (8) = 0$

For x = 1.8:

$h (1.8) = (1.8) ^ 2 - 8 (1.8)$

$h (1.8) = 3.24 - 14.4$

$h (1.8) = -11.16$

For x = x + 8:

$h (x + 8) = (x + 8) ^ 2 - 8 (x + 8)$

$h (x + 8) = x ^ 2 + 16x + 64-8x-64$

$h (x + 8) = x ^ 2 + 18x$

Answer:

The results of evaluating the function are:

$h (8) = 0$

$h (1.8) = -11.16$

$h (x + 8) = x ^ 2 + 18x$
