C) look at the scale factor for parts a and b. do they represent a reduction or enlargement of the empire state building? How do you know?
Answer:
Enlargement
Step-by-step explanation
It is enlargement, because it went up by three. Instead of reducing.
We cannot tell the result because the actual size of blocks used for modelling the Empire State Building is not known.
How are scale construction formed?For a particular scaled construct, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the corresponding lengths in the constructed scaled structure.
For case a) or b), we used the scale factors as:
1 block : x feet, where x was either 2 or 5 feet.
But we are not specified what size is of the block which is used to model the building.
It may be that block is greater than x feet, or may be smaller. This will decide whether there is enlargement or reduction of the actual building, respectively.
Thus, we cannot tell the result because the actual size of blocks used for modelling the Empire State Building is not known.

Solve the following system. y = (1/2)x^2 + 2x - 1 and 3x - y = 1 The solutions are (____)and (______ ) (remember to include the commas)
Answer:
x=0, 2. y=-1, 5.
Step-by-step explanation:
y=(1/2)x^2+2x-1
3x-y=1
---------------------
3x-y=1
y=3x-1
-----------
(1/2)x^2+2x-1=3x-1
(1/2)x^2+2x-3x-1-(-1)=0
(1/2)x^2-x-1+1=0
(1/2)x^2-x=0
factor out the x
x[(1/2)x-1]=0
zero property,
x=0, (1/2)x-1=0
-------------------
(1/2)x-1=0
1/2x=0+1
1/2x=1
x=1/(1/2)=(1/1)(2/1)=2/1=2
-----------------------------------
x=0, x=2
-------------
y=(1/2)(0)^2+2(0)-1=0+0-1=-1
-------------
y=3(0)-1=0-1=-1
-----------------------
y=(1/2)(2)^2+2(2)-1=(1/2)(4)+4-1=4/2+4-1=2+4-1=6-1=5
----------------------
y=3(2)-1=6-1=5
Answer:
The solutions are (0, -1) and (2, 5)
Step-by-step explanation:
y = (1/2)x^2 + 2x - 1 ------ eqn(I)
3x - y = 1
y = 3x - 1 ------------- eqn(II)
Equate eqn(I) & (II)
(1/2)x^2 + 2x - 1 = 3x - 1
Multiply each term by 2
x^2 + 4x - 2 = 6x - 2
x^2 + 4x - 6x = -2 + 2
x^2 - 2x = 0
x(x - 2) = 0
x = 0, 2
Substitute the values of x in eqn(II)
y = 3x - 1
When x = 0
y = 3(0) - 1 = 0 - 1 = -1
y = 3x - 1
When x = 2
y = 3(2) - 1 = 6 - 1 = 5
The solutions are (0, -1) and (2, 5)

Answer:
x = 6, 9
Step 1:
To solve this equation, we need to subtract 3 from both sides like this:
[tex]3\sqrt{x-5} +3(-3)=x(-3)\\3\sqrt{x-5} =x-3[/tex]
Step 2:
We square both sides (multiply using FOIL) to get rid of the radical.
[tex](3\sqrt{x-5} )^2 = (x-3)^2\\(3\sqrt{x-5} )^2: 9x-45\\ (x-3)^2: x^2+6x+9\\\\9x-45=x^2-6x+9[/tex]
If you did not understand how these were done, here is an example:
(x + 1)(x + 2)
First terms: x * x = x^2
Outer terms: x * 2 = 2x
Inner terms: 1 * x = x
2x - x = x
Last terms: 1 * 2 = 2
x^2 + x + 2
Step 3:
Solve for x:
9x - 45 = x^2 - 6x + 9
x^2 - 6x + 9 (+45) = 9x - 45 (+45)
x^2 - 6x + 54 (-9x) = 9x (-9x)
x^2 - 15x + 54 = 0
Factor:
(x^2 - 6x) + (- 9x + 54)
x(x - 6) - 9(x - 6)
Factor out (x - 6):
(x - 6)(x - 9) = 0
x - 6 = 0; 6 - 6 = 0
x - 9 = 0; 9 - 9 = 0
Our anwer: x = 6, 9

x = 22.62° to the nearest hundredthHope this helps you
Answer:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X. All of the angles of an equilateral triangle are equal.

What is the measure of the acute angle formed by the lines 3x–5y=–15 and 4x+2y=7?
Answer:
85.6 degrees.
Step-by-step explanation:
The given equations of lines are
[tex]3x-5y=-15[/tex]
[tex]4x+2y=7[/tex]
We need to find the measure of the acute angle formed by these lines.
[tex]Slope=\dfrac{-\text{Coefficient of }x}{\text{Coefficient of }y}[/tex]
Slope of given lines are
[tex]m_1=\dfrac{-3}{-5}=\dfrac{3}{5}[/tex]
[tex]m_2=\dfrac{-4}{2}=-2[/tex]
Angle between two lines is
[tex]\tan \theta = \left|\dfrac{m_1-m_2}{1+m_1m_2}\right|[/tex]
[tex]\tan \theta = \left|\dfrac{\dfrac{3}{5}-(-2)}{1+\dfrac{3}{5}(-2)}\right|[/tex]
[tex]\tan \theta = \left|\dfrac{\dfrac{3+10}{5}}{\dfrac{5-6}{5}}\right|[/tex]
[tex]\tan \theta = \left|\dfrac{13}{1}\right|[/tex]
[tex]\tan \theta = 13[/tex]
[tex]\theta = \tan^{-1}(13)[/tex]
[tex]\theta \approx 85.6^{\circ}<90^{\circ}[/tex]
Therefore, the acute angle between given lines is 85.6 degrees.

Hey there!
This problem will require a few steps to solve:
Step 1: Identify the "simple shapes" that make up the larger figure. Here, we see that there is a rectangle to the left, and a semicircle to the right.
Step 2: Find the area of the rectangle. This shouldn't be too hard, since we know that the formula for a rectangle's area is length times width. From the diagram, we have the length is 18cm, and the width is 12cm. 18 times 12=216.
Step 3: Find the area of the semicircle. This is slightly more difficult, but we know a semicircle is half of a circle, and the formula for circle area is [tex]\pi r^2[/tex]. Thus, the formula for a semicircle area is [tex]\frac{\pi r^2 }{2}[/tex]. We have d, or the diameter equal to 12, so the radius is 6, or half of the d. Plugging in the values, we find that the area for the semicircle is about 56.52.
Step 4: Add the areas of both simple shapes together: 216+56.52=272.52 cm^3.
Hope this helps :)
The radius of a circle is 6. Using T, which equation expresses the ratio of the circumference of the circle to the circle's diameter?
Answer:
Option (B)
Step-by-step explanation:
The given question is incomplete; here is the complete question.
The radius of a circle is 6. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?
A) C/6 = π
B) C/12= π
C) C = 6πr
D) C = 12πr
Formula to get the circumference of the circle is,
C = 2πr = π × D
Where C = circumference of the circle
D = Diameter of the circle
By dividing with D on both the sides of the formula,
[tex]\frac{\text{C}}{\text{D}}=\pi[/tex]
Since, diameter 'D' = 2r,
[tex]\frac{\text{C}}{\text{2r}}=\pi[/tex]
[tex]\frac{\text{C}}{2\times 6}=\pi[/tex]
[tex]\frac{\text{C}}{12}=\pi[/tex]
Therefore, equation given in Option (B) will be the correct expression.
Suppose a function f has an inverse. If f(2)=6 and f(3)=7, find: f−1(6)
Answer:
[tex]f^{-1}(6) = 2[/tex]
Step-by-step explanation:
Given
[tex]f(2) = 6[/tex]
[tex]f(3) = 7[/tex]
Required
[tex]f^{-1}(6)[/tex]
First, we need to determine the slope of the function using;
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
From the given parameters;
In [tex]f(2) = 6[/tex]
x = 2; y =6 --- Take this as x1 and y1
In [tex]f(3) = 7[/tex]
x = 3; y = 7 --- Take this as x2 and y2
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex] becomes
[tex]m = \frac{6 - 7}{2 - 3}[/tex]
[tex]m = \frac{- 1}{ - 1}[/tex]
[tex]m = 1[/tex]
Next, we determine the equation of the function using
[tex]y - y_1 = m(x - x_1)[/tex]
Substitute the values of x1,y1 and m
[tex]y - 6 = 1(x - 2)[/tex]
Open bracket
[tex]y - 6 = x - 2[/tex]
Add 6 to both sides
[tex]y - 6 + 6 = x -2 +6[/tex]
[tex]y = x + 4[/tex]
Next is to determine the inverse function by swapping the positions of x and y
[tex]x = y + 4[/tex]
Make y the subject of formula;
[tex]y = x - 4[/tex]
Replace y with [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x) = x - 4[/tex]
Now, we can solve for [tex]f^{-1}(6)[/tex]
Substitute 6 for x
[tex]f^{-1}(6) = 6 - 4[/tex]
[tex]f^{-1}(6) = 2[/tex]

The segments shown below could form a triangle.
A. True
B. False
Answer:
A True
Step-by-step explanation:
B vertices would be the top of an isosceles
As any equal sides can form an isosceles, the measure of the base could be any size and isnt relevant to the triangle unless we are looking for a calculation for its height, which does not determine shape only equation.
Therefore with sides of triangles if they are equal we cna make the shape consist of any length base as long as it measures less than double than either side length.
Therefore a 1cm base does apply and can form a triangle of two equal sides 7cm and 7cm as the diagram asks.
Answer:
true
Step-by-step explanation:
THE reason it true is because on on the lines doesn't equal to the 2 other lines

How did the temperature change if: At first it increased by 25% and then decreased by 40%
Answer:
24.6 % decrease
Step-by-step explanation:
Let x be the original temperature
Increase by 25%
x + .25x
1.25x
Decrease by 40%
The amount decreased is
(1.25x) *.40
.496x
Subtract that from 1.25x
1.25x - .496x
.754x
We need to find the percent decrease
1 - .754 = .246
24.6 % decrease
Answer:
Temperature decreased by 25%
Step-by-step explanation:
Let initial temperature be t
Step 1
Increase by 25%:
t + 25% = t + 0.25 t = 1.25 tStep 2
Decrease by 40%:
1.25 t - 40% = 1.25 t - 0.4 * 1.25 t= 1.25 t - 0.5 t = 0.75 tTemperature changed from t to 0.75 t
The difference in %:
0.75 t - t = -0.25 t = 25% decreaseTemperature decreased by 25%

No explanation needed :) Rebekah manages a yoga studio that charges each customer a one-time initial fee of $35 and an additional fee of $12 per class taken. Rebekah's goal is for each customer to spend at least $100 at the studio, and she wants to know the minimum number of classes a customer needs to take to meet that goal. Let C represent the number of classes a customer takes. 1) Which inequality describes this scenario? A. 35+C≤100 B. 35+3≥100 C. 35+12C≤100 D. 35+12C≥100 2) What is the minimum number of classes a customer can take for Rebekah to meet her goal?
The inequality that describes the scenario will be; 35 + 12C ≥ 100.
The minimum number of classes a customer can take for Rebekah to meet her goal is 6
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
One-time initial fee = $35
Additional fee per class = $12
Minimum target = $100
Number of classes = C
One-time initial fee + (Additional fee per class) x (Number of classes) ≥ Minimum target
The inequality that describes the scenario will be;
35 + 12C ≥ 100
Then Solve for C to know the minimum number of classes a customer can take for Rebekah to meet her goal,
12C ≥ 100 - 35
12C ≥ 65
C ≥ 65 / 12
C ≥ 5.42
Thus, The minimum number of classes a customer can take for Rebekah to meet her goal is 6
