Anit [1.1K]

Answer:

41x² - 27x + 27

Step-by-step explanation:

Perimeter of Rectangle:

= 2(20x²-12x+4) + 2(5x²-5x+15)

= 40x²-24x+8 + 10x²-10x+30

= 50x²-34x+38

Perimeter of Triangle:

= 6x²+6x+3x+3+3x²-2x+8

= 9x²+7x+11

Difference:

(50x²-9x²)+(-34x+7x)+(38-11)

= 41x² - 27x + 27

A parabola contains the points (5,0) and (-4,0) . What is the equation of its axis of symmetry?
sesenic [268]
Notice, (5,0) and (-4,0), the y-coordinate is 0, namely those are x-intercepts, the vertex is halfway between them, namely the vertex is at 0.5 over the x-axis.

therefore the equation of the axis of symmetry will be the x = 0.5.

The heights of adult men in America are normally distributed, with a mean of 69.8 inches and a standard deviation of 2.61 inches
Dvinal [7]

Answer:

1.99

Step-by-step explanation:

We have been given the heights of adult men in America are normally distributed, with a mean of 69.8 inches and a standard deviation of 2.61 inches. We are asked to find the z-score of height of man with 6 feet 3 inches.

We will use z-score formula to solve our given problem.

z=\frac{x-\mu}{\sigma}, where,

z = z-score,

x = Sample score,

\mu = Mean,

\sigma = Standard deviation,

6 feet 3 inches = 72+3 inches = 75 inches

z=\frac{75-69.8}{2.61}

z=\frac{5.2}{2.61}

z=1.99233716475

z\approx 1.99

Therefore, the z-score for the man with height of 6 feet 3 inches is 1.99.
