Help Please What Is The Value Of B?

Answers

Answer 1

Answer:

3[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Find 'c' first by using the Altitutude Rule:

4/c = c/9

cross-multiply to get:

c = [tex]\sqrt{36}[/tex] or 6

Now you can find 'a' by using the Pythagorean Theorem:

4² + 6² = a²

a = [tex]\sqrt{52}[/tex]

Now you can find 'b' by using the Pythagorean Theorem:

([tex]\sqrt{52}[/tex])² + b² = (9+4)²

52 + b² = 169

b² = [tex]\sqrt{117}[/tex]

b = [tex]\sqrt{117}[/tex] = [tex]\sqrt{3}[/tex][tex]\sqrt{3}[/tex][tex]\sqrt{13}[/tex]

b = 3[tex]\sqrt{13}[/tex]

Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How many flowers did she deliver if she made $21?

Answers

Answer:

she delivers 9 flower plugs.

Step-by-step explanation:

in a standard equation the equation would be 21 = 2x + 3 and if you isolate the x you would have to first subtract the 3 from both sides and that would leave you with 18 = 2x and then you have to divide both sides by 2 and get 9=x

Enter an equation for the word sentence. Use the variable n.

The sum of a number and 4.4 is 8.1.

Answers

Answer:

[tex]n + 4.4 = 8.1[/tex]

Step-by-step explanation:

We know we have to write an algebraic equation for the sentence - so "translate" the phrases of the sentence step-by-step. Let the unknown number be represented by the variable n, as the question states.

Start with the phrase "the sum of a number and 4.4." A sum comes as a result of adding numbers together - therefore the first part of the equation must be [tex]n + 4.4[/tex].

Next, the sentence says "is 8.1." The "is" indicates that the expression we just wrote equals something, so that number must be 8.1. Therefore, the whole equation must be [tex]n + 4.4 = 8.1[/tex].

Using the given equation find the missing coordinates of the points and then find the slope of the line for each equation y= 0.3x + 1; A(...;9), B(5;...) The slope is

Answers

Answer:

[tex]A = (\frac{80}{3},9)[/tex]

[tex]B = (5,2.5)[/tex]

The slope is 0.3

Step-by-step explanation:

Given

[tex]y = 0.3x + 1[/tex]

[tex]A = (-,9)[/tex]

[tex]B = (5,-)[/tex]

Required:

Fill in the gap and calculate the slope

In [tex]A = (-,9)[/tex]

[tex]y = 9[/tex] and x is ??

Substitute 9 for y in [tex]y = 0.3x + 1[/tex]

[tex]9 = 0.3x + 1[/tex]

Collect Like Terms

[tex]0.3x = 9 - 1[/tex]

[tex]0.3x = 8[/tex]

[tex]x = \frac{8}{0.3}[/tex]

[tex]x = \frac{80}{3}[/tex]

So:

[tex]A = (-,9)[/tex]

[tex]A = (\frac{80}{3},9)[/tex]

In [tex]B = (5,-)[/tex]

[tex]x = 5[/tex] and y is ??

Substitute 5 for x in [tex]y = 0.3x + 1[/tex]

[tex]y = 0.3 * 5 + 1[/tex]

[tex]y = 1.5 + 1[/tex]

[tex]y = 2.5[/tex]

So:

[tex]B = (5,-)[/tex]

[tex]B = (5,2.5)[/tex]

Calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2.5-9}{5 - \frac{80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{15- 80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{-65}{3}}[/tex]

[tex]m = \frac{-6.5*3}{-65}[/tex]

[tex]m = \frac{-19.5}{-65}[/tex]

[tex]m = 0.3[/tex]
