Find the length of side Y (this is from the geometry for enjoyment and challenge textbook) PLEASE ANSWER ASAP IT'S DUE TOMORROW!!!

Answers

Answer:

y= 3

Step-by-step explanation:

The triangle on the left is a right triangle, so we can use trig functions to solve for the missing side, y.

First, find the length of the side that both triangles are connected to.

tan30=x/9

Isolate the x variable and solve.

9(tan30)=x

x= 5.19615

Now use the Pythagorean Theorem to solve for the side length, y.

a^2+ b^2 = c^2

(5.19615)^2+ b^2= 6^2

c= 3

Answers

[tex]\huge \bf༆ Answer ༄[/tex]

Let's find the slope of line passing through given points ~

[tex] \sf \dfrac{y2 - y}{x2 - x1} [/tex]

[tex] \sf \dfrac{1 - 0}{7 - 6} [/tex]

[tex] \sf \dfrac{1}{1} [/tex]

[tex] \sf1[/tex]

Hence, slope of the line will be 1.

Answer:

Step-by-step explanation:

slope = (change in y)/(change in x)

slope = (1 - 0)/(7 - 6)

slope = 1/1 = 1

Find the
17th
term of the arithmetic sequence whose common difference is d=5 and whose first term is a1 = 1.

Answers

The [tex]17th[/tex] term of the arithmetic sequence is [tex]81[/tex]

An arithmetic sequence is a sequence of numbers produced by adding a fixed number, called the common difference, to a term in the sequence to get the next term of the sequence.

The formula for calculating the [tex]nth[/tex] term of a sequence is

[tex]a_n=a_1+(n-1)d[/tex]

where

[tex]a_n=\text{the nth term}\\a_1=\text{the first term}\\d=\text{the common difference}[/tex]

from the question

[tex]n=17\\d=5\\a_1=1[/tex]

from this information, we can calculate the [tex]17th[/tex] term of the sequence thus

[tex]a_n=a_1+(n-1)d\\a_{17}=1+(17-1)\times5\\=81[/tex]

so, [tex]a_n=81[/tex]

2(4w+7)=62

Whats the answer how do I do it?

Answers

[tex]2(4w + 7) = 62[/tex]

Divide both sides by 2

[tex] \frac{2(4w + 7)}{2} = \frac{62}{2} \\ [/tex]

[tex]4w + 7 = 31[/tex]

Subtract both sides 7

[tex]4w + 7 - 7 = 31 - 7[/tex]

[tex]4w = 24[/tex]

Divide both sides by 4

[tex] \frac{4w}{4} = \frac{24}{4} \\ [/tex]

[tex]w = 6[/tex]

Answer:

w=6

Step-by-step explanation:

Step 1 : Simplifying

2(4w + 7) = 62

Step 2 : Recorder the terms :

2(7 + 4w) = 62

(7 * 2 + 4w * 2) = 62

(14 + 8w) = 62

Solving-

14 + 8w = 62

Solving for the variable 'w'

Move all terms containing w to the left side, all other terms to the right.

Add '- 14' to each side of the equation.

14 + - 14 + 8w = 62 + - 14

Combine like terms: 14 + - 14 = 0

0 + 8w = 62 + - 14

Combine like terms: 62 + - 14 = 48

8w = 48

Divide each side by '8'

W = 6

Simplifying

W = 6

Transformation involves changing the form of a function

The true statement is (a) it is stretched horizontally by a factor of 2 and translated up, 3 units.

The function is given as:

[tex]y = \log(x)[/tex]

Start by stretching the graph of [tex]y = \log(x)[/tex], horizontally by a factor of 2.

So, we have:

[tex]y = \log(2 \times x)[/tex]

[tex]y = \log(2x)[/tex]

Next, shift the function up by 3 units.

So, we have:

[tex]y = \log(2x) + 3[/tex]

Hence, the true statement is (a)
