Answer:

BD  \approx 2.6

Step-by-step explanation:

By angle bisector theorem:

\frac{3.4}{BD}  =  \frac{6.5}{4.9}  \\  \\ BD =  \frac{3.4 \times 4.9}{6.5}  \\  \\ BD =  \frac{16.66}{6.5}  \\  \\ BD = 2.56307692 \\  \\ BD  \approx 2.6

HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Phoenix [80]

Answer:

3

Step-by-step explanation:

So we have the function:

f(x)=3x^2+2x-5

To evaluate the value of f(-2), substitute -2 for x. Thus:

f(-2)=3(-2)^2+2(-2)-5

Square first:

f(-2)=3(4)+2(-2)-5

Multiply:

f(-2)=12-4-5

Now, subtract:

f(-2)=8-5=3

So:

f(-2)=3

And we're done!

Explain how the function y=-1/3|x+2|+5 is transformed from the original function of y=-1/3|x|.
Illusion [34]

The original function of y = -1/3|x| was translated 2 units to the right and 5 units up.

<h3>The types of transformation.</h3>

In Mathematics, there are four (4) main types of transformation and these include the following:

  1. Dilation
  2. Rotation
  3. Reflection
  4. Translation

<h3>What is a translation?</h3>

In Mathematics, the translation of a geometric figure (shape) to the right simply means adding a digit to the numerical value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure (shape) that is translated up simply means adding a digit to the numerical value on the y-coordinate (y-axis) of the pre-image.

In this scenario, the original function was shifted 2 units to the right and then shifted 5 units up to produce the new function as follows:

Original function (x, y)    →     New function (x + 2, y + 5)

y = -1/3|x|                         →        y = -1/3|x + 2| + 5

A cell phone plan costs $30 per
irga5000 [103]

Hi :)

If a cell phone plan costs 30 per month and charges 15 cent per text message and 200 text messages were sent,

The base charge is 30 dollars, multiply 0.15 by 200

30 + (0.15 * 200)

30 + (30)

For this month,

$60

Hope this helps,

Jeron

P.S (brainliest? only if you think i really helped you)
