Need help with dilation with a scale factor of 1/2 centered at (−1, 3)
A scale factor of 1/2 makes the triangle half the size of the original.
The original is 4 units tall, so 1/2 scale makes the new one 2 units tall.
It is 6 units long, so 1/2 would be 3 units long.
Now since the scale factor is centered at (-1,3) fine the midpoint between The top left corner of the triangle and the center point:
Midpoint ( -1-5/2 , 3+7/2)
Midpoint = (-6/2 , 10/2)
Midpoint = -3,5

How do you do this question?
Answer: C) 1
===========================================================
One way is to graph the function f(x) = ln(x)/(x-1) and you'll see the curve slowly approach y = 1 when x approaches 1 from either side. Check out the attached image labeled "figure 1" for this graph.
---------
You can use a table to see this in action. See figure 2 (attached below as well).
-----------
Another alternative is to use L'Hospital's rule. This is because we get the indeterminate form 0/0 after plugging x = 1 into the original function.
if y = ln(x), then dy/dx = 1/x
If y = x-1, then dy/dx = 1
So f(x) = ln(x)/(x-1) becomes (1/x)/1 = 1/x
If you plug in x = 1, you get 1/x = 1/1 = 1.
Regardless of which method you use, the limiting value is 1
The sum of the measures of angle 5 and angle 6 is equal to 180° and the sum of the measures of angle 2 and angle 3 is equal to 180° because angles on a _____ _____ measure 180°.
Fill in the blanks
Final answer:
The blanks are filled with 'straight line' as angles on a straight line sum to 180°, which is a key concept in geometry related to the properties of angles and triangles.
Explanation:
The sum of the measures of angle 5 and angle 6 is equal to 180° and the sum of the measures of angle 2 and angle 3 is equal to 180° because angles on a straight line measure 180°. This concept is related to the geometric property that when two angles lie on the same line and add up to form a straight angle, their measures sum up to 180°.
In geometry, specifically the study of polygons and angles, we learn that a triangle is a three-sided figure lying on a plane with three angles adding up to 180°. This is called the Triangle Sum Theorem, which is fundamental to understanding the properties of triangles and other polygons.

Answer:
Perimeter = 32.44 unit
Area of triangle = 30 unit²
Step-by-step explanation:
By distance formula distance between (a,b) and (c,d) is [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]
So, we have
[tex]AB=\sqrt{(16-2)^2+(2-8)^2}=15.23\\\\BC=\sqrt{(16-6)^2+(2-2)^2}=10\\\\AC=\sqrt{(2-6)^2+(8-2)^2}=7.21[/tex]

How much of a spice that is 3% salt should be added to 175 ounces of a spice that is 6% salt in order to make a spice that is 5% salt?
PLS HELP ME
Answer:
Let x represents the ounces of first spice.
From the given statements, you draw a table as shown below:
ounces of spice Percentage ounces of salt
First spice x 3% 0.03x
Second spice 175 6% 175(0.06)
Final mixture x+ 175 5% (x+175)(0.05)
Now, to solve for x;
Final spice = First spice + second spice
[tex]0.03x+175(0.06) = (x+175)(0.05)[/tex]
[tex]0.03x + 10.5 = 0.05x + 8.75[/tex]
Subtract 10.5 on both sides we have;
[tex]0.03x + 10.5 -10.5= 0.05x + 8.75-10.5[/tex]
Simplify:
[tex]0.03x= 0.05x -1.75[/tex]
Subtract 0.05x on both sides;
[tex]0.03x - 0.05x= 0.05x -1.75-0.05x[/tex]
Simplify:
[tex]-0.02x= -1.75[/tex]
Divide both sides by -0.02, we get;
x = 87.5 ounces
Therefore, 87.5 ounces of spices i.e 3% salt should be added to 175 ounces of a spice that is 6% salt in order to make a spice that is 5% salt

Given that cosΘ = 3/2
and that Θ lies in quadrant IV, determine the value of sinΘ.
A) -1/2
B) 1/2
C) square root 2/2
D) square root 3/2
Answer:
None of the Above
Step-by-step explanation:
As it is given that
cosФ= 3/2
and Ф lies in quadrant 4
Now in quadrant 4 we know that by the rules of trigonometry that
cos Ф is positive in 4th quadrant also in 4th quadrant
and sinФ is negative in 4th quadrant
also we know that by simple rules of trigonometry in a right angled triangle
cos Ф=[tex]\frac{Base}{Hypotenuse}[/tex] =[tex]\frac{3}{2}[/tex]
now from the law of trigonometry
cos²Ф+sin²Ф=1
From this we derive the value of sinФ
solving the equation
sin²Ф=1-cos²Ф
Putting in the values of cos Ф
sin²Ф=1-[tex](\frac{3}{2})^{2}[/tex]
sin²Ф=1-[tex](\frac{9}{4})[/tex]
solving the fraction
sin²Ф=[tex](\frac{4-9}{4})[/tex]
sin²Ф=[tex](\frac{-5}{4})[/tex]
so taking square root of both sides
[tex]\sqrt{sin^{2}\alpha}=\sqrt{\frac{-5}{4} }[/tex]
here
[tex]\alpha[/tex]=Ф
so it becomes
sin Ф=[tex]\frac{\sqrt{-5} }{2}[/tex]
as we know that in imaginary numbers
[tex]\sqrt{-1}[/tex] = ι
so the given becomes
sin Ф=[tex]\frac{{-5ι} }{2}[/tex]
Which is the value of sin Ф
And in the given values we can see that it is none of the values
Also seeing the question we can see that the question is absurd because
cos Ф= base / hypotenuse
in our question we can see that base =3 and hypotenuse = 2
but in real geometry this is the rule that hypotenuse can never be smaller then base either it is equal to base or greater then base
the formula for finding value of finding hypotenuse is
hypotenuse ² = base ² + perp ²
so this formula shows that if perp is 0 then hypotenuse will be equal to base
in other cases it would be greater then base

The ratio of green pepper plants to red pepper plants in joes garden is 2 to 7 if joe has 20 more red peppers plants than green pepper how many of each does he have
Joe has 8 green pepper plants and 28 red pepper plants in his garden.
Explanation:Let's denote the number of green pepper plants as G and the number of red pepper plants as R.
According to the given information, the ratio of green pepper plants to red pepper plants is 2 to 7.
This can be written as G:R = 2:7.
It is also mentioned that there are 20 more red pepper plants than green pepper plants. This can be written as R = G + 20.
Now, we can substitute the value of R from the second equation into the first equation:
G:G+20 = 2:7
By cross-multiplying, we have 7G = 2(G+20).
Simplifying the equation, we get 7G = 2G + 40.
Subtracting 2G from both sides, we have 5G = 40.
Dividing both sides by 5, we get G = 8.
Therefore, there are 8 green pepper plants and 8 + 20 = 28 red pepper plants in Joe's garden.

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the total cost of pizza with toppings be = c
Let the number of toppings be = t
Let the initial cost of the pizza be = $ 12
Let the cost of each toppings be = $ 1.50
So , the total cost of the pizza with toppings c = ( cost of each toppings x number of toppings ) + initial cost of the pizza
Substituting the values in the equation , we get
Total cost of the pizza with toppings c = 1.50 ( t ) + 12
Therefore , the value of A is c = 1.50 ( t ) + 12
Hence , the equation is c = 1.50 ( t ) + 12 with slope m = 1.50 and y intercept as 12

Final answer:
The equation in slope-intercept form for the total cost C of a pizza with t toppings when a pizza costs $12 and each additional topping costs $1.50 is C = 1.50t + 12.
Explanation:
To find the equation in slope-intercept form for the total cost C of a pizza with t toppings at a pizza parlor that charges $12 for a large cheese pizza and $1.50 for each additional topping, we can establish a relationship between the number of toppings and the total cost. Let's use the slope-intercept form of the linear equation, y = mx + b where y is the total cost, m is the cost per topping, x is the number of toppings, and b represents the base price of the pizza without toppings.
The base price of the pizza is $12, which is the y-intercept, and the additional cost per topping is $1.50, which is the slope. Therefore, the equation that represents the total cost C of the pizza with t toppings is:
C = 1.50t + 12

If line ET is tangent to circle A at T and the measure of ∠TNG =27° what is the measure of ∠NET?
A 63°
B 90°
C 100°
D 126°
Answer:
∠NET = 63°
Step-by-step explanation:
We are given a figure with a circle A and a line ET which is tangent to the circle at the point T. Also, the measure of the angle TNG is given to be 27° and we are to find the measure of angle NET.
If we recall the point of tangency, we will remember that the point where a tangent touches the radius of a circle is always a right angle.
That makes the angle NTE to be 90°.
Putting the sum of these angles equal to 180 to get:
90 + 27 + ∠NET = 180
∠NET = 180 - 90 - 27
∠NET = 63°

You work at a coffee house. Roasted beans retain approximately 3/5 of their weight of their initial weight approximately what percent of their initial weight do they retain?
Answer:
60 percent
Step-by-.step explanation:
You need to convert 3/5 to a percentage.
This is 3*100 / 5
= 300 / 5
= 60 per cent
Final answer:
Roasted beans retain 3/5 of their initial weight, which is equivalent to 60% when converted to a percent.
Explanation:
To convert this fraction to a percentage, we follow the steps outlined in the explanation: dividing the numerator by the denominator to get a decimal value, and then multiplying by 100 to express it as a percentage. In this case, 3 divided by 5 equals 0.60, which when multiplied by 100 gives 60%.
The roasted beans retain approximately 3/5 of their initial weight after roasting. To determine what percentage of their initial weight they retain, we convert the fraction 3/5 to a percent. To do this:
Divide the numerator of the fraction by the denominator: 3 ÷ 5 = 0.60.Multiply the resulting decimal by 100 to convert it to a percentage: 0.60 × 100 = 60%.Therefore, roasted beans retain 60% of their initial weight.

Help me please!Algebra Two!!
Answer:
This means the function touches the x-axis at -1 but does not cross.
Step-by-step explanation:
A polynomial graph has several features we look for to determine the equations.
The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity.Vice versa. If I know the zero and multiplicity, I can make an accurate sketch of the functions behavior.This means the function touches the x-axis at -1 but does not cross.
