Answer:

  f(3) = g(3)

Step-by-step explanation:

The graph shows f(3) = 6, and it shows g(3) = 6. Then ...

  f(3) = g(3)

To determine if two functions f and g are equal at certain points, one must refer to their definitions or graphs. If f(x) and g(x) are defined as x², they are the same function as they produce identical outputs for any numerical input.

The student's question pertains to function comparison and the evaluation of these functions at specific points. The statement "f(6) = g(3)" implies that the value of the function f when x is 6 is equal to the value of function g when x is 3.

The answer to the question will rely on the specific definitions or graphical representations of the functions f and g, provided in the original question or accompanying materials.

For the functions defined by f(x) = x² and g(s) = s², f and g are indeed the same function since they both return the square of their input, regardless of the variable used to represent that input.

Since both function names are simply placeholders for the operation being performed (squaring), f and g yield the same output for any identical numeric input.

Based on the examples in the reference information, we can see that two different functions could have the same graph if they result in the same set of points on a Cartesian plane. This would make them the same function in the context of their graphical representation.

Answer:

Actual mean: 223 pages

Predicted mean / estimate: 225 pages

Explanation below

Step-by-step explanation:

Mean = total amount ÷ # of numbers

155 + 214 + 312 + 198  + 200 + 170 + 250 + 260 + 215 + 256

Add

2,230

# of numbers = 10

2,230 ÷ 10 = 223

The exact mean is 223

If I were to predict the mean, I would say that a good estimation would be around 225, because I see that the highest number in the data set is 312, and the lowest is 155. If 312 is rounded down to 300, and 155 is rounded down to 150, the number exactly in the middle of 300 and 150 is 225.

Actual mean: 223 pages

Predicted mean: 225 pages

Answer:

i) Therefore option A is Correct.   Δ ECD   [tex]\sim[/tex] Δ ACB by the SAS ( Side Angle Side) Similarity Theorem.

ii) Yes it can be proven that ED || AB after proving that Δ ECD   [tex]\sim[/tex] Δ ACB

Step-by-step explanation:

i) CE = [tex]\frac{1}{2}[/tex] AC ..... given

ii)  CD =  [tex]\frac{1}{2}[/tex] CB .... given

iii)  Therefore [tex]\frac{CE}{AC} = \frac{CD}{CB} = \frac{1}{2}[/tex]

iv)  Angle ACB or ∠C is common to Δ ACB and Δ CED.

v) Therefore from the above 4 equations we can say that by

   SAS theorem the two triangles are similar , that is ,  Δ ECD   [tex]\sim[/tex] Δ ACB .

 Therefore option A is Correct.

 vi)  Yes it can be proven that ED || AB after proving that Δ ECD   [tex]\sim[/tex] Δ ACB.

Since Δ ECD   [tex]\sim[/tex] Δ ACB , therefore ∠CED = ∠CAB  and ∠CDE = ∠CBA.

Therefore we can say that ED is parallel to AB or that ED || AB.

The transformer is 27.5 ft above the ground.

Solution:

The given image is like a triangle.

Angle 'L' represents the triangle is right triangle.

Use Pythagoras theorem to find the answer.

Base of the triangle = 12 ft

Hypotenuse of the triangle = 30 ft

Height of the triangle = x

Using Pythagoras theorem,

[tex]\text{Base} $^{2}+$ Height $^{2}=$ Hypotenuse $^{2}$[/tex]

[tex]12^2+x^2=30^2[/tex]

[tex]144+x^2=900[/tex]

Subtract 144  on both sides of the equation.

[tex]x^2=900-144[/tex]

[tex]x^2=756[/tex]

Taking square root on both sides.

[tex]x=27.5[/tex]

Hence the transformer is 27.5 ft above the ground.

It is a function

A function is a relation between two sets that associates to every element of a first, called set A, one and only one element of the second set, called set B. In other words, we can't have any element of the set A assigned to more than one element in the set B. Put another way, we can't have repeated elements of the first set. In this problem we have a relation given by the table:

[tex]\begin{array}{cc}x & y\\5 & -2\\7 & -2\\9 & -2\end{array}[/tex]

So the assignation is as follows:

[tex]5 \rightarrow -2 \\ \\ 7 \rightarrow -2 \\ \\ 9 \rightarrow-2[/tex]

As you can see every element of the set A (set x) is assigned to the same element in the set B (set y) but we have no repeated element in the first set, so this is a function.

Answer:

The cup can hold 235.5 cubic cm of popcorn.

Step-by-step explanation:

Given:

A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.

Use 3.14 as an approximation for pi.

Now, to find cubic cm of popcorn the cup can hold.

Radius ( r ) = 5 cm.

Height ( h ) = 9 cm.

π = 3.14 ( as per question ).

So, to get the cubic cm of popcorn the cup can hold we put formula of volume:

[tex]Volume = \pi r^2\frac{h}{3}[/tex]

[tex]Volume=3.14\times 5^2\times \frac{9}{3}[/tex]

[tex]Volume=3.14\times 25\times 3[/tex]

[tex]Volume=235.5\ cubic\ cm.[/tex]

Therefore, the cup can hold 235.5 cubic cm of popcorn.

Answer:

x = - 1, x = 5

Step-by-step explanation:

Given

(x + 1)(x - 5) = 0

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x - 5 = 0 ⇒ x = 5

Answer:

Step-by-step explanation:

x+1*x-5=0

Since we know the answer to the equation is 0, that means that it doesn't matter if we multiply x, add to it, or subtract from it, it will all eventually become 0.

So:

            X=0

The simplified expression is:

[tex]g(x)-f(x) = x^2-6x-1[/tex]

Solution:

Given that the expression is:

[tex]g(x) - f(x) = (x^2-x+3)-(5x+4)[/tex]

We have to simplify the expression

The expression can be simplified by combining the like terms

Like terms are terms that have the same variables and powers. The coefficients do not need to match

From given,

[tex]g(x) - f(x) = (x^2-x+3)-(5x+4)\\\\Remove\ the\ paranthesis\ and\ solve\\\\g(x) - f(x) = x^2-x+3-5x-4\\\\Combine\ the\ like\ terms\\\\g(x)-f(x) = x^2-x-5x+3-4\\\\Add\ the\ like\ terms\\\\g(x)-f(x) = x^2 -6x + 3 - 4\\\\Add\ the\ constants\\\\g(x)-f(x) = x^2 -6x -1[/tex]

Step-by-step explanation:

In parallelogram RECT is a rectangle,

EC = x + y , RT = 2x - y, RE = 2x + y and TC = 3x - 3

To find, the values of the variable = ?

∵ The opposite sides are equal.

∴ RE = TC and RT = EC

2x + y = 3x - 3

⇒ x - y = 3                   .......... (1)

Also,

2x - y = x + y

⇒ x - 2y = 0               .......... (2)      

Subtracting (1) from (2), we get

∴ x - y - (x - 2y ) = 3 - 0

⇒ x - y - x + 2y = 3

⇒ y = 3

Put y = 3 in equation (1), we get

x - 3 = 3  

⇒ x = 3 + 3 = 6

∴ x = 6 and y = 3

Thus, the values of the variable are 3 and 6.

Answer:

10 boxes in the top row.

192 boxes in entire display.

Step-by-step explanation:

Let n be the number of rows.

Given:

Total number of rows = 8

Boxes in bottom row = 38

And each row has four fewer boxes than the row below it.

Solution:

Part A:

We know that the bottom row has 38 boxes and each row has four fewer boxes than the row below it.

Using below function for determining the number of boxes in each rows.

[tex]f(n)=38-(8-n)4[/tex]

Where:

n = Number of row.

We need to find the boxes in the first row.

So, substitute n = 1 in above function.

[tex]f(1)=38-(8-1)4[/tex]

[tex]f(1)=38-7\times 4[/tex]

[tex]f(1)=38-28[/tex]

[tex]f(1)=10[/tex]

Therefore, 10 boxes in the top row.

Part B:

Total boxes in the entire display.

Using formula as given below to determine the sum of the boxes in entire display.

[tex]S_{n} = \frac{n}{2}(f(1)+f(n))[/tex]

Substitute n = 8, f(1) = 10 and f(8) = 38 in the above equation.

[tex]S_{8} = \frac{8}{2}(10+38)[/tex]

[tex]S_{8} = 4(48)[/tex]

[tex]S_{8} = 4\times 48[/tex]

[tex]S_{8} = 192\ boxes[/tex]

Therefore, 192 boxes in the entire display.

Number of creamy peanut butter jars is 20.

Final answer:

The factory made 20 jars of creamy peanut butter, which is calculated by finding 20% of the total 100 jars produced.

Explanation:

The student has asked how many jars of creamy peanut butter were made if a factory produced 100 jars and 20% of them contained creamy peanut butter. To find the answer, we simply need to calculate 20% of 100 jars.

Here is the calculation:

First, we convert the percentage to a decimal: 20% = 0.20.

Next, we multiply the total number of jars by this decimal: 100 jars × 0.20 = 20 jars.

Therefore, the factory made 20 jars of creamy peanut butter.

Answer:
