Answer:

2.3 units

Step-by-step explanation:

$\tan 25\degree =\frac{AC}{5}\\\\0.46630 = \frac{AC}{5}\\\\AC = 0.46630 \times 5\\AC =2.3315\\AC = 2.3 \: units$

Answer: 2.3

Step-by-step explanation:

We can use a trigonometric function to find AC

With respect to angle B (25º) BC is adjacent and AC is opposite.

The trigonometric function that relates adjacent and opposite is tangent.

$tan=\frac{opposite}{adjacent}$

Solve for opposite.

$opposite=tan*adjacent$

$o=tan(25)*5\\o=2.3$

Find all the zeros of the polynomial function p(x) = x3 – 5x2 + 33x – 29

hram777 [196]

Answer:

$\large \boxed{\sf \ \ x=1, \ \ x=2+5i, \ \ x=2-5i \ \ }$

Step-by-step explanation:

Hello,

I assume that we are working in $\mathbb{C}$ , otherwise there is only one zero which is 1. Please consider the following.

First of all, <u>we can notice that 1 is a trivial solution</u> as

$p(1) = 1^3-5\cdot 1^2 + 33\cdot 1-29=1-5+33-29=0$

It means that (x-1) is a factor of p(x) so we can find two real numbers, a and b, so that we can write the following.

$p(x)=(x-1)(x^2+ax+b)=x^3+ax^2+bx-x^2-ax-b=x^3+(a-1)x^2+(b-a)x-b$

Let's identify like terms as below.

a-1 = -5 <=> a = -5 + 1 = -4

b-a = 33

-b = -29 <=> b = 29

$\boxed{ \ p(x)=(x-1)(x^2-4x+29) \ }$

Now, we need to find the zeroes of the second factor, meaning finding x so that:

$x^2-4x+29=0 \ \text{ complete the square, 29 = 25 + 4} \\ \\ x^2-2\cdot 2 \cdot x+2^2+25=0 \\ \\ (x-2)^2=-25=(5i)^2 \ \text{ take the root } \\ \\x-2=\pm 5i \ \text{ add 2 } \\ \\ x = 2+5i \ \text{ or } \ x = 2-5i$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

What is the value of the digit 9 in the numbers 913,256

oksian1 [2.3K]

900,000 or nine hundred thousand

<h3>Further explanation</h3>

Problem: given 913,256.

Question: what is the value of the digit 9.

This is a problem with place value.

Let's set the place values from 913,256 consecutively as follows.

In the thousands period: 9 hundred thousands, 1 ten thousands, 3 one thousands.
In the units period: 2 hundreds 5 tens 6 ones.

Let us say in word form: nine hundred thirteen thousand two hundred fifty-six.

Hence, the value of the digit 9 in the numbers 913,256 is 900,000 or nine hundred thousand.

<u>Notes:</u>

Just as a reminder, the digits in large numbers are in groups of three places, i.e.,

hundreds,
tens,
ones (or units).

The groups are called periods, i.e.,

millions period;
thousands period;
ones or units period.

Commas are typically used to separate the periods.
