(a,1/b) and (b,1/a) find the slope of the line joining the points whose coordinates are

Mathematics

pogonyaev3 years ago
6 0

Answer:

m=\frac{1}{ab}

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(a,1/b) and (b,1/a)

substitute

m=\frac{1/a-1/b}{b-a}

m=\frac{\frac{b-a}{ab}}{b-a}

m=\frac{1}{ab}

Ok so I found the area of a rectangle.
Kay [80]

Answer:

  circle area = 1963.495 ft²

Step-by-step explanation:

<u>Given</u>

  A rectangle 550 ft by 350 ft packed with circles on a rectangular grid

<u>Find</u>

  the area of the largest circle that can be packed this way

<u>Solution</u>

The diameter of the circle must be a factor of both 350 and 550. We want the diameter to be the largest such factor. We can write the factors of 350 and 550 as ...

  • 350 = 50 × 7
  • 550 = 50 × 11

The largest factor common to both numbers is 50, so that will be the diameter of the largest circle that will fit on a square grid.

The area of a circle is commonly given by the formula ...

  A = πr² . . . . . where r represents the radius of the circle.

The radius is half the diameter, so will be (50 ft)/2 = 25 ft. And the area of the circle is ...

  A = π(25 ft)² = 625π ft² ≈ 1963.495 ft²

The area of one circle is about 1963.495 square feet.

_____

The total number of circles is 11×7 = 77. Their total area is 77×1963.495 ft² ≈ 151,189 ft². This is 151,189/192,400 ≈ 78.54% of the total area of the rectangle.

Tires have a normal distribution with a mean of 70000 miles and a standard deviation of 4400 miles. What proportion of tires wil
yarga [219]
Let T = the distance, in miles, a tire lasts

T ~ N(70000,4400<span>²</span>)

P(T \geq 75000) 
 = P(Z \geq \frac{75000 - 70000}{4400})
 = P(Z \geq \frac{25}{22})
 ≈ P(Z \geq 1.14)
 = 1 - P(Z < 1.14)
 ≈ 1 - 0.8729
 = 0.1271
