Answer:

hello your question is incomplete attached below is the complete question

<em>answer</em> :   1

Step-by-step explanation:

Given Function:

F(x,y)=\left \{ {{1/4(2x+y)} \atop {0}} \right.      for    0<x<1, 0<y<2

                                            elsewhere.

Evaluating the marginal density of the writing test score at point

X = 1/2  = 1/4 ( 4x + 2 ) = 1/4 ( 4 * 1/2 + 2 ) = 1

attached below is the detailed solution

willhelmina has 8.3 ounces of peanut butter if she makes 5 sandwiches with an equal amount of peanut butter on each how much pea
nadezda [96]

Answer:

Wilhelmina will put 1.66 ounces of peanut butter on each sandwich.

Step-by-step explanation:

Given:

Ounces of peanut butter Wilhelmina has = 8.3

Number of sandwiches prepared by her = 5

According to the question:

She puts equal amount of peanut butter on each sandwiches.

So,

We have to find the quantity of peanut butter used for each sandwiches.

Here the distribution is equal so we have to use division method.

Let ounces of peanut butter applied on each sandwich be 'x'

⇒ x= \frac{Ounces\ of\  peanut\ butter}{No.\ of\ sandwiches}

⇒ x=\frac{8.3}{5}

⇒ x =1.66 Ounces

So each sandwich will get 1.66 ounces of peanut butter.

Simplify the expression so there’s only one positive power for the base, -5.
Yuri [45]

Given:

The expression is

(-5)^7\div  (-5)^2

To find:

The simplified form of the given expression so there is only one positive power for the baser -5.

Solution:

We have,

(-5)^7\div  (-5)^2

=\dfrac{(-5)^7}{(-5)^2}

Using the properties of exponents, the given expression can be written as

=(-5)^{7-2}                  [\because \dfrac{a^m}{a^n}=a^{m-n}]

=(-5)^{5}

Here, the base is -5 and the exponent is 5.

Therefore, the correct option is C.

What is the exact volume of the cylinder?
suter [353]

Answer:

<h2>volume of the cylinder = 128πin³</h2>

Step-by-step explanation:

The question is incomplete. Here is the complete question;

'What is the exact volume of the cylinder? 32π in³ 64π in³ 128π in³ 512π in³ Cylinder with radius labeled 4 inches and height labeled 8 inches'

Volume of a cylinder = πr²h

r is the radius of the cylinder

h is the height

Given r = 4in

h = 8in

Volume =  π(4)²*8

volume of the cylinder = 16π*8

volume of the cylinder = 128πin³

Show that the sum of two irrational numbers can be rational or irrational. Provide two examples of each.
Otrada [13]
Pi is irrational, but 2-Pi is also irratonal. Let a = Pi and b=2-Pi. In this example a+b=2 which is rational.
Other example is a=3.2437629... ad Infinitum and b=6.756230... where the digits all sum to 9 therefore make a+b=10
