A machinist has 13 wrought-iron rods to mill. Each rod weighs 24 oz. What is the total weight of the rods in pounds? (Enter your answer as a simplified mixed number.)

the orders served by Laura are 22, the orders served by Aldo are 29 and the orders served by Juan are 44.

Total number of orders served on Monday at the school cafeteria = 95

Juan served 2 times as many orders as Laura and Aldo served 7 more orders than Laura.

Let the orders served by Laura be x

Orders served by Juan = 2 x

Orders served by Aldo = x + 7

So, we get the equation as:

x + 2 x + x + 7 = 95

4 x + 7 = 95

4 x = 95 - 7

4 x = 88

x = 88 / 4

x = 22

x + 7 = 22 + 7 = 29

2 x = 2 (22) = 44

Therefore, we get that, the orders served by Laura are 22, the orders served by Aldo are 29 and the orders served by Juan are 44.

Let p and q be two variables and

a₁p+ b₁q=c₁              

a₂p+ b₂q =c₂        

Where a₁, a₂, b₁, b₂, c₁, c₂ are  constants   then  we can solve these simultaneous equations by substitution take value of p from equation (1) and then put it in (2) to get an equation for q only and then solve for q. Put value of q in equation (1) to get value of p.

Let the 5 friends ordered  x number of $4 items , y number of $6 and z number of $7 items

They ordered total a total of 24 items.

Then, x+ y + z = 24      ....(1)

Given that $4  was twice the $6 and $7 items combined

Then, x =2( y+ z )

Put this expression of x in (1),we get

2(y+ z)+ y + z =24

3y + 3z =24

y + z =8   ....(2)

Also given that they split the bill at the end, they each owed $23

Therefore total bill will be 5 times $23 = 5*23 = $ 115

Total money spent on bill = $ 4x+6y+7z

Thus, 4x+6y+7z = 115

Again put  x =2(y+ z) here and get

8(y+ z) +6y+ 7z =115

8y +8z + 6y +7z = 115

14y +15z = 115   ....(3)

Therefore, (2) and (3) is the system of equations we have to solve.

From (2) we get y =8 -z

Put this value of y into (3) and get

14(8-z)+15z =115

112 - 14z +15z =115

z= 115-112 = 3

Then, y = 8-z = 8-3 = 5

x = 2(y+ z)= 2(3+5) =16

Therefore x= 16 , y = 5, z=3  from system of equations generate by (2) and (3)

Answer:

[tex]g(x) = (x-4)^2\; and \;h(x)= x^2-4 \;are\;\bold{not}\;equivalent[/tex]

Step-by-step explanation:

For two functions g(x) and h(x)  to be equivalent, they must have the same domain and range.

Domain is the set of all values of x(inputs)  that result in a real and defined value for the function

Range is the set of all values of the function that it can take given the values of x in the domain

[tex]g(x)=(x-4)^2=16-8x+x^2\\[/tex]

Can be rewritten as
[tex]g(x) = x^2 -8x + 16[/tex]  The domain of g is unrestricted, g can be any value so the

Domain of g: [tex]-\infty < x < \infty[/tex]
Range of g: Since [tex](x-4)^2[/tex] is always positive including 0, the range of g(x) is g(x) ≥ 0

[tex]h(x) = x^2 - 4[/tex]

Domain of h : [tex]-\infty < x < \infty[/tex] since x can be any value and we will still get a real number as function output

However x² is always zero or a positive number so we have the restriction
x² ≥ 0

Subtract 4 on both sides

x²-4 >= -4

But the above is nothing but the outputs of h(x)

So h(x) >= -4 and can be written as -4 ≤ x ≤ ∞

So we can see that, while the domains of the two functions are the same, their ranges are different

Hence the two functions g(x) and h(x) are not equivalent

Tip
If you have difficulty determining domain and range, take a specific value of x for both functions and check if the function output values are the same. It may not always be easy choosing an appropriate x value depending on the function

For x = 0

g(0) = (0-4)² = (-4)² = 16

h(0) = 0^2 -4 = 0-4 = -4

So we get different output values for the same input value for both functions and therefore they are not equivalent

Only the graph on the left is a function, due to the one on the right failing the vertical line test.

2.

This is asking for a positive x-value of the two functions, we can find that by setting them equal to a common value and then equal to each other.

Lets set them both equal to x.

First equation:

[tex]y=x^2\\\sqrt{y}=x[/tex]

Second equation:

[tex]y^2=x[/tex]

Now we set them equal to each other:

[tex]y^2=\sqrt{y}[/tex]

Then solve for y by squaring both sides:

[tex]y^4=y[/tex]

Now we solve by factoring:

[tex]y^4=y\\y^4-y=0\\y(y^3-1)=0\\y^3-1=0\\y^3=1\\y=\sqrt[3]{1}\\ y=1[/tex]

The value of the expression when c = 5 and d = 42  is 12

The given parameters are:

c = 5 and d = 42

The expression is given as:

d - 6c

To evaluate the expression when c = 5 and d = 42, we substitute c = 5 and d = 42 in expression d - 6c

This is represented as

d - 6c = 42 - 6 * 5

Evaluate the product in the above expression

So, we have

d - 6c = 42 - 30

Evaluate the difference in the above expression

So, we have

d - 6c = 12

Answer:

x = 22.5

∠ADE = 67.5

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180° and the given is a right triangle so we can find the value of x easily:

90 + x + 3x = 180 add like terms

90 + 4x = 180 subtract 90 from both sides

4x = 90 divide both sides by 4

x = 22.5

To find the measure of angle ADE we use the same equation:

90 + 22.5 + ∠ADE = 180 add like terms

112.5 + ∠ADE = 180 subtract 112.5 from both sides

∠ADE = 67.5

The rectangular equivalence to the parametric equations is;

(x - 2)²/9 + (y + 1)²/4 = 1

We want to find the rectangular equivalence to the parametric equations;

x(θ) = 3cosθ + 2

y(θ) = 2sinθ − 1

where 0 ≤ θ < 2π .

Making the trigonometric ratio the subject gives us;

cosθ = (x - 2)/3

sinθ = (y + 1)/2

Now, from trigonometric identities, we know that;

cos²θ + sin²θ = 1

Thus;

((x - 2)/3)² + ((y + 1)/2)² = 1²

(x - 2)²/9 + (y + 1)²/4 = 1
