Find the diagonal BD simplify you answer (Explain)

Mathematics
1 answer:
Dima020 [189]3 years ago
5 0

Answer:

See below:

Step-by-step explanation:

First of all, you will see that diagonal BD is a angle bisector for Angles <ABC and <ADC. Now, knowing that it is a square.

We see that the angle bisector splits the angles into 45 degrees each due to the sum of angles in a square being 360 degrees hence giving us 4 right angles.

Now, if we see this, we see that we have a 45 45 90 Triangle!

The theorem states that the hypotenuse is equal to x\sqrt{2}.

Hence, we get our answer of 5\sqrt{2}!

If f(1)=3 and f(n)=-2f(n-1)+1,then f(5)=
Drupady [299]
F(5) = - 2f(4) + 1
f(4) = -2f(3) + 1
f(3) = -2f(2) + 1
f(2) = -2f(1) + 1
Therefore:
 f(2) = -2(3) + 1 = -5
f(3) = -2(-5) + 1 = 11
f(4) = -2(11) + 1 = -21
Therefore f(5) = -2(-21) + 1 = 43

A byte consists of 8 bits. A kilobyte is 2^10 bytes. How many bits are in a kilobyte?
Furkat [3]

Answer:

8,192 bits

Step-by-step explanation:

1. Determine how many bytes are in a kilobyte.

To do this, we simply need to get 2 to the tenth power (2 * 2 * 2 * 2 * 2 *2 * 2 * 2 * 2 * 2), which ends up being 1,024 bytes in one kilobyte.

2. Determine how many bits are in 1,024 bytes.

Since 1 byte = 8 bits, all we have to do is multiply 1,024 bytes by 8 bits, which leaves us with 8,192 bits.

Answer: 1 kilobyte = 8,192 bits

2.85 rounded to the nearest hundredth <br> A. 2.861<br> B. 2.849<br> C. 2.842<br> D. 2.805
blagie [28]

Answer:

B) 2.849

Step-by-step explanation:

Given: 2.85 which is rounded to the nearest hundredth place.

To find the number, the thousandth place must be greater than or equal to 5.

Here 2.849 has the thousandth place greater than 5

When we round off 2.849 to the nearest hundredth place, we get

2.85

Therefore, answer is B) 2.849

Hope this will helpful.

Thank you.

The price of a train ticket consists of an initial fee of $5 plus a fee of $2.75per stop
mamaluj [8]

The complete question describes the use of word problems to represent inequalities. The $21 means that there is a limit to the number of stops she can take using the train.

The inequality that represents this scenario is:

5 + 2.75x \le 21

From the complete question, we have the following parameters:

Initial Fee = $5

Rate per stop = $2.75

Amount = $21

The inequality that represents the scenario is as follows:

Initial Fee + Rate * Number of stops <= Amount

We use <= because the total charges must not exceed the amount.

Let the number of stops be x.

The above formula becomes

5 + 2.75 * x \le 21

5 + 2.75x \le 21
