a) 2 letters to church and 4 letters to union

b) $ 1000

A  statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given data:

Letter writing time for church = 2 hours

Follow up required for church = 1 hour

Letter writing time for labor union = 2 hours

Follow up required for labor union = 3 hour

Funds from church = $ 100

Funds from union = $ 200

now, let 'x' be the number of letters written to church

and let  'y' be the number of letters written to labor union

According to the given conditions

maximum timing for letter writing = 12 hours

So,

2x + 2y ≤ 12 hours

x + y ≤ 6 hours

Now, maximum time for follow up = 14 hours

1x + 3y ≤ 14 hours  

on solving the both the equations

    x +   y = 6

- ( 1x + 3y = 14 )

----------------------

0 - 2y = -8

y = 4 hours

and, x + 4 = 6

x = 2

Now,

money raised  = (2 × $ 100) + (4 × $ 200)

= $ 1000

Answer:

  (a)  1568 in³

  (b)  1728 in³

Step-by-step explanation:

You want to know the volume of the box that can be formed from the pattern shown, and the maximum volume that can be had by changing the 4-inch dimension.

The volume of the box is the product of its length, width, and height. The height of the box is shown as 4 inches.

The length is shown as the difference between 36 inches and twice the 4-inch dimension:

  length = 36 -2(4) = 28 . . . . inches

The width is shown as half the difference between 36 inches and twice the 4-inch dimension. That will make it be half the length.

  width = (1/2)(36 -2(4)) = 14 . . . . inches

Then the volume of the box from the pattern shown is ...

  V = LWH = (28 in)(14 in)(4 in) = 1568 in³

Using the above observations regarding dimensions, we can write the volume in terms of the height of the box (x) as ...

  height = x

  length = 36 -2x

  width = 18 -x

  volume = (x)(36 -2x)(18 -x) = 2x³ -72x² +648x

The maximum volume will be found at the value of x that makes the derivative of volume be zero:

  V' = 6x² -144x +648 = 0

  x² -24x +108 = 0 . . . . . . . . divide by 6

  (x -6)(x -18) = 0 . . . . . . . . factor

Values of x that make the derivative zero are x=6 and x=18. The original equation is a cubic with a positive leading coefficient, so we know these values correspond to a local maximum and a local minimum, respectively.

The largest volume possible is obtained with a corner cut of 6 inches. That volume is ....

  V = (6)(36 -2·6)(18 -6) = 6(24)(12) = 1728 . . . . cubic inches

The largest volume possible is 1728 in³.

Answer: 495

Step-by-step explanation: If the car traveled for 90 miles on 2 gallons of gas and we now have 11 gallons Divide 2÷11 = 5.5 or



90×5.5 = 495

The number of miles Aubrey's car can travel is 495 miles

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the distance traveled by Aubrey's car for 11 gallons be = A

Now , the equation will be

The distance traveled by Aubrey's car for 2 gallons = 90 miles

So ,

The distance traveled by Aubrey's car for 1 gallon = distance traveled by Aubrey's car for 2 gallons / 2

The distance traveled by Aubrey's car for 1 gallon = 90 / 2

The distance traveled by Aubrey's car for 1 gallon = 45 miles

So , the equation will be

The distance traveled by Aubrey's car for 11 gallons A = The distance traveled by Aubrey's car for 1 gallon x 11

The distance traveled by Aubrey's car for 11 gallons A = 45 x 11

The distance traveled by Aubrey's car for 11 gallons A = 495 miles

Therefore , the value of A is 495 miles

Hence , The number of miles Aubrey's car can travel is 495 miles

The direction cosines of the line are:

x = 8 / √116

y = 6 / √116

z = -4 / √116

Direction ratio helps in knowing the components of a line or a vector with reference to the three-axis, the x-axis, y-axis, and z-axis respectively.

We have,

Let the direction ratio of the line be (x, y, z)

The line is perpendicular to the lines whose direction cosines are proportional to 3,-2,3 and 1,-2,-1.

Now we have,

3x - 2y + 3z = 0 _____(1)

x - 2y - z = 0 _____(2)

We will find the value of x, y, and z using cross product.

x / 2 + 6 = y / 3 + 3 = z / -6 + 2

x / 8 = y / 6 = z / -4

We get,

x = 8

y = 6

z = -4

The direction cosines of the line are:

x = 8 / √8² + 6² + (-4)²

x = 8 / √64 + 36 + 16

x = 8 / √116

y = 6 / √116

z = -4 / √116

The function g (x) is called an inner function and the function f (x) is called an outer function. Hence, we can also read f [g (x)] as “the function g is the inner function of the outer function f”.

Given that,

f(x) = 2x²+2  and

g(x)=x2-1

So find the (f- g)(x).

(f- g)(x) means,

Multiply x into f and g functions

Then, (f- g)(x) = f(x)-g(x)

Replace with f(x) and g(x) values in this equation

So,

(f- g)(x)= f(x)-g(x)

          = (2x²+2) - (x2-1)

Distribute the subtraction to all three of the last terms.          

          = 2x²+2-2x+1

          = 2x²-2x+2+1

Combine like terms

  (f- g)(x) = 2x²-2x+3

Therefore,

f(x) = 2x²+2 and

g(x)=x2-1,    

So,

The number of cars in the parking lot is 105.

The first step is to determine the total number of cars that the parking lot can accommodate. This can be determined by multiplying the number of rows by the total number of cars in each row.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

Total number of cars that can be in the parking lot  = number of rows x number of cars in each row

6 x 20 = 120

The next step is to subtract the number of empty spaces from the capacity of the parking lot . Subtraction is the operation that is used to determine the difference between two or more numbers.

Number of cars = capacity of the parking lot - empty spaces

120 - 15 = 105

The solution is Option A.

The geometric mean of the two numbers 34 and 60 is A = 2√510

The geometric mean is given by the root of the product of the two numbers

Geometric Mean (GM) is the average value or mean which signifies the central tendency of the set of numbers by finding the product of their values

Let the two numbers be a and b

The geometric mean between a and b is A = √ab

Given data ,

Let the equation be represented as A

Now , the value of A = geometric mean between the numbers

Let the first number be a

The value of a = 34

Let the second number be b
