Answer:

Area is = 36

Perimeter is = 26

Step-by-step explanation:

To find the area of a rectangle multiply the width and length of the rectangle.

So the width is 4 and the length is 9

4 x 9 = 36

To find the perimeter of a rectangle use formula P=2(l+w)

So . . .

P = 2(4+9)

P = 2(13)     P= 26  

Explanation:

The rule to use here is log(x)-log(y) = log(x/y)

So,

log(6)-log(3) = log(6/3) = log(2)

Answer:

log(2)

Step-by-step explanation:

As we have,

log(a)−log(b)=log(a/b)

Replace 'a' as 6 and 'b' as 3.

Then we get,

[tex]\hookrightarrow log(6)-log(3)\\\\\hookrightarrow log(\frac{6}{3} )\\\\\hookrightarrow log(2)[/tex]

The area of the training field will be 6933.06 square meters.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 86 m long and 54 m wide.

Then the area of the training field will be

Area = area of a rectangle + area of a circle

Then we have

Area = 86 x 54 + 3.14 x 27 x 27

Area = 4644 + 2289.06

Area = 6933.06 m²

Using the normal distribution, it is found that there is a 0.84 = 84% probability that a randomly selected high jumper has a personal best between 227 and 265 cm.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by:

[tex]\mu = 208, \sigma = 19[/tex]

The probability that a randomly selected high jumper has a personal best between 227 and 265 cm is the p-value of Z when X = 265 subtracted by the p-value of Z when X = 227, hence:

X = 265:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{265 - 208}{19}[/tex]

Z = 3

Z = 3 has a p-value of 0.9987.

X = 227:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{227 - 208}{19}[/tex]

Z = 1

Z = 1 has a p-value of 0.1587.

0.9987 - 0.1587 = 0.84.

0.84 = 84% probability that a randomly selected high jumper has a personal best between 227 and 265 cm.

The solution of the quadratic equation is irrational because 11² - 4*3*9 is not a perfect square.

An irrational quadratic equation is an equation that contains two irrational solutions making the equation not to be able to be solved through factorisation.

Using the quadratic equation formula to solve, the irrational solutions are gotten below,

X = -b +√b²- 4ac/2a

where a = 3; b= 11 ; C = 9

X = -3+√11²-4*3*9/2*3

X= -3+√ 121-108/6

X= -3 +√13/6

X =-3/6 +√13/6

X= -1/2 + √13/6

Therefore,X = -1/2 +√13/6 or

X = -1/2 - √13/6

The solution are two irrational numbers that are not prefect squares.

Answer: 2287.08 ft²

Step-by-step explanation: Correct for plato/Edmentum

Answer:

The answer is B, 396 square units.

Step-by-step explanation:

We can separate the figure into five individual polygons and sum up their areas to find the total surface area of the figure.

The base of the figure is 8*12 = 96.

The rectangle at the back of the figure is 8*9 = 72.

To find the area of the rectangle on top, we need to first find second side length. To do this, we use the pythagorean theorem (a^2 + b^2 = c^2) on the right triangle, so 9^2 + 12^2 = c^2 --> 225 = c^2 --> c = 15. Next, we find the area of the rectangle which is 8*15 = 120.

The area of the triangle to the side is 1/2*12*9 (9 is height because it's a right triangle) = 54, so the area of both triangles is 54*2 = 108.

Now we sum up the areas: 96 + 72 + 120 + 108 = 396

Answer:

The width and the length of the rectangular pen will be equal to w=11 feet and the length=20 feet.

The perimeter is defined as the sum of all the sides of the figure. In a rectangle, it is the sum of all the sides of the rectangle.

For this problem, we need to find what perimeter is equal to 62 feet. To find the perimeter of a rectangle we do:

P=2w+2l

where p = perimeter, w = width, and l = length

This problem says that the length is 9 feet longer than the width, so the length would be:

w+9

Now we know what the perimeter and length is, so we can put those into the equation above. This is what it will look like:

62=2w+2(w+9)

and that will solve like so:

62=2w+2w+18

62=4w+18

44=4w

w=11

Now that we know the width we can plug it into our first equation to find the length:

62=(2(11)+2l

62=22+2l

40=2l

l=20

Your width is 11 feet and your length is 20 feet.

hence the width and the length of the rectangular pen will be equal to w=11 feet and the length=20 feet.
