Equation of the given line will be :

  • y = 4x - 3

now, let's plug the value of x as the x - coordinate of the above point (-2 , 9) to check whether it lies on the line or not.

  • y = 4( - 2)  -  3

  • y =  - 8 - 3

  • y =  - 11

now, since value of isn't equal to the y - coordinate of the given point, so the point doesn't lies on the line.

Answer:

Equation of the given line will be :

y = 4x - 3

now, let's plug the value of x as the x - coordinate of the above point (-2 , 9) to check whether it lies on the line or not.

y = 4( - 2) - 3y=4(−2)−3

y = - 8 - 3y=−8−3

y = - 11y=−11

now, since value of isn't equal to the y - coordinate of the given point, so the point doesn't lies on the line.

The Garden Task
Igoryamba

If the perimeter of the garden is (14x - 32) ft and has a side length of (x + 2) ft:

  • the perimeter = 24 ft
  • the area = 36 sq. ft
  • if the perimeter of the garden is doubled, the perimeter of the new garden = 48 ft
  • if the area of the garden is doubled, the area of the new garden = 72 sq. ft

<em><u>Recall</u></em>:

  • A square has equal side lengths
  • Perimeter of a square = 4(side length)
  • Area of a square = (side $ length)^2

<em><u>Given:</u></em>

Perimeter of square (P) = (14x - 32) $ ft

Side length (s) = (x + 2) $ ft

<em><u>First, let's find the </u></em><em><u>value of x</u></em><em><u> by creating an </u></em><em><u>equation </u></em><em><u>using the </u></em><em><u>perimeter </u></em><em><u>formula:</u></em>

  • Perimeter of a square = 4(side length)

  • Plug in the values

(14x - 32) = 4(x + 2)

  • Solve for x

14x - 32 = 4x + 8\\\\14x - 4x = 32 + 8\\\\10x = 40\\\\x = 4

<em><u>Find how much fencing would be needed (</u></em><em><u>Perimeter </u></em><em><u>of the fence):</u></em>

  • Perimeter of the fence = (14x - 32) $ ft

  • Plug in the value of x

Perimeter of the fence = 14(4) - 32 = 24 $ ft

<em><u>Find the </u></em><em><u>area </u></em><em><u>of the garden:</u></em>

  • Area of the garden = (side $ length)^2

Area = (x + 2)^2

  • Plug in the value of x

Area = (4 + 2)^2 = 6^2 = 36 $ ft^2

<u><em>Find the </em></u><u><em>perimeter </em></u><u><em>if the garden size is doubled:</em></u>

  • Perimeter of the new garden = 2 x 24 = 48 ft

<em><u>Find the </u></em><em><u>area </u></em><em><u>if the garden size is doubled:</u></em>

  • Perimeter of the new garden = 2 x 36 = 72 sq. ft

In summary, if the perimeter of the garden is (14x - 32) ft and has a side length of (x + 2) ft:

  • the perimeter = 24 ft
  • the area = 36 sq. ft
  • if the perimeter of the garden is doubled, the perimeter of the new garden = 48 ft
  • if the area of the garden is doubled, the area of the new garden = 72 sq. ft

Question 5 (2) x cube - 3x square 9x - 5
kakasveta [241]
Please, post the instructions along with your question, and if possible share the question in symbolic form, not in words.

Do you mean Question #5?  By  (2) x cube, do you mean 2x^3?

I strongly suggest that you use lots of parentheses (   ) to show how your numbers are grouped, and not to use " x " to denote multiplication (use " * " for that, please.    

If only you'll clear this up, I'd be happy to help.

I will assume that your post is   2x^3 - 3(9x-5)^2.

Then 2x^3 - 3(81x - 90x + 25).  Does this have any resemblance to what you wanted me to see in your post?

Dr. Ashby is studying the heart rate of adult men. Preliminary data suggests that the standard deviation of heart rates for adul
jok3333 [9.3K]

Answer:

n=42 adult men

Step-by-step explanation:

-The minimum sample size to get a desired margin of error, E is calculated using the formula:

n\geq( \frac{z\sigma}{E})^2

-Given that \sigma=7.5, \ \ E=3\ , \ z_{0.005}=2.58, we can substitute to solve for n in the above formula:

n\geq (\frac{z\sigma}{E})^2\\\\\therefore n=(\frac{z_{\alpha/2}\sigma}{E})^2\\\\=(\frac{2.58\times7.5}{3})^2\\\\=41.6025\approx42

Hence, the desired minimum sample size, n is 42 adult men.
