Step-by-step explanation:

first the domain of f(x) : 2*-1 -1 < 2x-1 < 2*4 -1 = -3 <2x-1 < 7

now the domain of g(x) : 4/(3-2) < 4/(x-2) < 4/(5-2) = 1.3 < 4/(x-2) < 4

now h(x) = -3 - 1.3 <f(x) - g(x) < 7-4 = - 4.3 < f(x) - g(x) < 3

The area of a circle with a diameter of 16 meters is equal to: B. 64π square meters.

Mathematically, the area of a circle can be calculated by using this formula:

Area = πr²

Where:

r represents the radius of a circle.

Note: Radius = diameter/2 = 16/2 = 8 meters.

By substituting the radius into the formula for the area of a circle, we have the following;

Area of circle = π × 8²

Area of circle = 64π square meters.

The Transformation is graph of f is translated 3 units up and 7 units to the right.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given: y=f(x-7) + 3.

As, from the Rule the f(x, y) --> f(x-c, y) shows the horizontal shift on right side.

So, the function is shifted 7 units to the right.

Now, the rule f(x)--> f(x) + c shows the vertical translation up by c units.

Place value is the basis of our entire number system. This is the system in which the position of a digit in a number determines its value.

The number 42,316 is different from 61,432 because the digits are in different positions.

here,, we have,

i) the 4 in the hundredths place will give us the value 0.04 = 4/100

ii) the value of 4 in the tens place gives us the value = 4 × 10 = 40

iii) to compare the value of 4 in the hundredths place to the value of 4 in the tens place  we divide the value obtained in i) by the value obtained in ii).

Therefore we get the value of the comparison as = (4/100)/40

The final solution for the initial value problem: y = −e∫x dx√40 − ∫x2e∫x dx − ∫y2e∫x dx.

The given initial value problem is yy′+x=x2+y2 with y(3) = −√40. To solve this we make the substitution U = u' and u = y. This transforms the given equation into the linear differential equation in x, u, and u': u'+xu=x2+u2. To solve this, we can use the integrating factor method. Multiplying both sides by the integrating factor e∫x dx gives us u'e∫x dx + xue∫x dx = x2e∫x dx + u2e∫x dx. Taking the integral of both sides, we obtain ue∫x dx = ∫x2e∫x dx + ∫u2e∫x dx + c, where c is the constant of integration. Solving for u, we have u = c/e∫x dx − ∫x2e∫x dx − ∫u2e∫x dx. Using the fact that u = y, we can substitute this expression into the equation to obtain the solution in terms of x and y: y = (c/e∫x dx) − ∫x2e∫x dx − ∫y2e∫x dx. Using the initial condition y(3) = −√40, we can solve for c to get c = −e∫3 dx√40. Substituting this into the solution, we get the final solution for the initial value problem: y = −e∫x dx√40 − ∫x2e∫x dx − ∫y2e∫x dx.

Step-by-step explanation:

just took the test!

Consider the simple given arrangement of three resistors, the total equivalent resistance of the arrangement will be smaller than the resistor C.

Please refer to the attached picture below for the give resistors arrangement.

The three resistors are arranged in a paralel circuit. Hence, the total equivalent resistance for the arrangement will be:

1/R total = 1/Ra + 1/Rb + 1/Rc

Where:

Ra = A

Rb = b

Rc = C

A < B < C

Then, the total resistance will be:

1/R total = 1/A + 1/B + 1/C

    1       = BC + AC + AB

R total              ABC

R total =           ABC      

                BC + AC + AB

Next, we will try to choose any random numbers that meet the resistors condition to proof this condition. This time, we choose:

A = 3

B = 2

C = 1

Then, we need to subtitute each number to its positions:

R total =          3 x 2 x 1      

                  2(1) + 3(1) + 3(2)

R total =          6

The cost per square inches of the circular pie is C = $ 0.164

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

Let the cost per square inch of the apple pie be C

Let the area of the circle be represented as A

Now , the diameter of the circle is d = 10 inches

So , the radius of the circle r = d/2 = 5 inches

And , area of the circle = πr²

Substituting the values in the equation , we get

Area of Circle A = π x ( 5 )²

Area of Circle A = 78.5398 inches²

The cost of the apple pie = $ 12.85

Now , the cost for 78.5398 inches² of apple pie = $ 12.85

So , the cost for 1 inches² of pie C = 12.85 / 78.5398

On simplifying the equation , we get

The cost per square inches C = $ 0.164

Hence , the cost per square inches is $ 0.164

The GCF of the two expressions is (y + 5).

The greatest common factor (GCF) of two or more expressions is the largest expression that is a factor of each of the expressions. To find the GCF of two expressions, we need to factor out the common factors from each expression.

Given expressions: z(y + 5) - 3(y + 5)

We can start by factoring out (y + 5) from both terms:

z(y + 5) - 3(y + 5) = (y + 5)(z - 3)

So, the GCF of the two expressions is (y + 5).

The greatest common factor (GCF) is the largest positive integer that is a factor of two or more numbers. It is a useful concept in mathematics, especially in the study of numbers and their properties. The GCF helps us simplify expressions by cancelling out common factors and reducing the complexity of expressions. For example, the GCF of 12 and 18 is 6, meaning that 6 is the largest number that is a factor of both 12 and 18. To find the GCF, we can use prime factorization to identify the common factors and then multiply those factors to obtain the GCF.

So, a = 0 (What I am saying is the first blank is a, the blank next to it is b, etc)

Solve for b:

Plug in x=0

4(0) = 0

So, b = 0

Solve for c:

Plug in x=1

2(1) + 1 + 1

2 + 1 + 1

= 2  + 2

b = 4

Jorge's water bottle holds 2 2/5 liters of water, which can be written as 22/5 liters or 4.4 liters.

Jorge's estimate of his water bottle holding about 1/2 liter more water than Carmen's is reasonable because:
