Tom performs a dilation of ⅓ on a triangle. He then classifies the image and pre-image as being congruent. Is Tom correct? Why or why not? Explain you answer down below.
Answer: Tom is incorrect.
Step-by-step explanation: Congruent is defined as having exactly the same angle measurements and exactly the same side lengths.
In the 1/3 dilation, the angles will remain the same, but all the sides will be shorter, 1/3 the lengths of the original image. The image and pre-image are not congruent. They are similar.

A zip line from the tallest tree in the forest to the campsite is 145 feet. The angle of elevation from the ground to the top of the tree is 58°. How tall is the tree? Round your answer to the nearest foot.
Answer:
123 ft
Step-by-step explanation:
create a right angle triangle from the given info.
your perpedicular will be tree height and hypotneus will be 145 feet
sin 45=Tree height/145
122.96=tree height
123 ft
The height of the tree will be equal to 123 feet.
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that a zip line from the tallest tree in the forest to the campsite is 145 feet. The angle of elevation from the ground to the top of the tree is 58°.
Create a right-angle triangle from the given info. your perpendicular will be tree height and your hypotenuse will be 145 feet

Cranberry juice costs $6.30 per quart and apple juice costs $3.60 per quart. Terrence wants to make a cranberry-apple juice mixture that costs $4.50 per quart. He wants to know how many quarts q of cranberry juice he should mix with 4 quarts of apple juice. Which equation below represents the situation
Answer:
D. 6.30q + 14.40 = 4.50(q + 4)
Step-by-step explanation:
Which equation below represents the situation
A. 3.60(q – 4) + 25.20 = 4.50q
B. 3.60q + 25.20 = 4.50(q + 4)
C. 6.30(q – 4) + 14.40 = 4.50q
D. 6.30q + 14.40 = 4.50(q + 4)
Cost of Cranberry juice = $6.30 per quart
Cost of apple juice = $3.60 per quart.
Let
Cost of q quarts of Cranberry juice = $ 6.30q
Cost of 4 quarts of apple juice = $3.60×4= $ 14.40
Total quarts of cranberry-apple juice mixture = q+4
Terrence wants to make a cranberry-apple juice mixture that costs $4.50 per quart
Total revenue = price × quantity
= $4.50(q+4) (1)
Total cost of the mixture = Cost of q quarts of cranberry juice + cost of 4 quarts of apple juice.
= 6.30q + 14.40 (2)
Equate both equations
$4.50(q+4) = 6.30q + 14.40
It can also be written as
6.30q + 14.40 = 4.50(q + 4)
The correct answer is
D. 6.30q + 14.40 = 4.50(q + 4)

A circle has an area of approximately 78.5 square units. If the center of the circle is at Left-parenthesis 2 comma 4 right-parenthesis. Which of the following points is on the circle? A. Left-parenthesis negative 6 comma 4 right-parenthesis B. Left-parenthesis 2 comma negative 1 right-parenthesis C. Left-parenthesis negative 4 comma negative 4 right-parenthesis D. Left-parenthesis 2 comma negative 9 right-parenthesis
Answer:
The answer is (2, -1)
Step-by-step explanation:
The area of the circle is:
A = r²π
We know
A = 78.5
π = 3.14
78.5 = r² * 3.14
r² = 78.5 : 3.15
r² = 25
r = √25 = 5
The standard form equation of a circle is:
(x - h)² + (y - k)² = r²
We have:
(2, 4)
⇒ h = 2
k = 4
r = 5
(x - h)² + (y - k)² = r²
(x - 2)² + (y - 4)² = 5²
(x - 2)² + (y - 4)² = 25
Now, let's substitute all choices:
(-6, 4):
(-6 - 2)² + (2 - 4)² = 25
(-8)² + (-2)² = 25
64 + 4 = 25
68 = 25
Wrong
(2, -1)
(2 - 2)² + (-1 -4)² = 25
0² + (-5)² = 25
0 + 25 = 25
25 = 25
Right

The perimeter of the rectangle below is
118 units. Find the length of side AB
.
This a question about perimeter and equation, let's see how to solve that:
The perimeter of a rectangle is the sum of its 4 sides. In this case, we know that the perimeter is 118. We can do an equation with these datas:
[tex]\boxed{AB + BC + CD + DA = 118}[/tex]
We also know other informations: the side AB is equal to [tex]4y+3[/tex] and de side BC is equal to 3y. In a recltangle, parallels sides have the same value. So, the side CD is equal to [tex]4y+3[/tex] and the side DA is equal to 3y.
Now, we have these datas:
[tex]AB + BC + CD + DA = 118\\\\AB = CD = 4y + 3\\BC = DA = 3y[/tex]
Let's do and solve an equation:
[tex]AB + BC + CD + DA = 118\\\\4y+3 + 3y + 4y+3 + 3y = 118\\14y + 6 = 118\\14y = 118 - 6\\14y = 112\\y = \frac{112}{14} \\y = 8[/tex]
So, the value of y is 8. Let's replace the value of y in the side AB:
[tex]4y + 3\\4\times 8 + 3 = 35[/tex]
Therefore, the length of side AB is 35.

О
a dilation of figure 1 with scale factor 12 then a translation
a dilation of figure 1 with scale factor 3/2 then a translation
a dilation of figure 1 with scale factor 3/2 then a reflection
Answer:
Option (4)
Step-by-step explanation:
Length of segment between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
From the figure attached,
Distance between A(0, -3) and B(3, 0) = [tex]\sqrt{(3-0)^2+(0+3)^2}[/tex]
AB = [tex]3\sqrt{2}[/tex]
Distance between A'(-3.5, -4.5) and B'(-8, 0)
Length of A'B' = [tex]\sqrt{(-3.5+8)^2+(-4.5-0)^2}[/tex]
A'B' = [tex]4.5\sqrt{2}[/tex]
Scale factor for dilation = [tex]\frac{4.5\sqrt{2}}{3\sqrt{2}}=1.5[/tex]
Therefore series of transformations will be,
A dilation of figure 1 with scale factor of [tex]\frac{3}{2}[/tex] and then a reflection.
Option (4) will be the answer.
after multiplying,we have a(b plus c)
Answer:
The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.
Step-by-step explanation:
Solve the equation. If the equation is an identity, choose identity. If it has no solution, choose no solution. 4(t + 2) = 10
Answer & Step-by-step explanation:
4(t + 2) = 10
4t + 8 = 10
4t = 2
t = 1/2

the first term of a geometric progression is 12 and the second term is -6. Find the (i) the tenth term of the progression (ii) the sum to infinity
Step-by-step explanation:
a1=ar⁰=12 A2=ar¹=-6
a=12 ar=-6
12r=-6
r=-6/12
r=-1/2
a10=ar⁹
=12*(-1/2)⁹
=12*(-512)
=-3/128
S∞ = a1 / (1-r )
=12/(1-1/2)
=12*1/2
=6
The tenth term of the progression will be -3/128, and the sum to infinity will be 6.
What is geometric progression?The geometric progression defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
We have been given that the first term of a geometric progression is 12 and the second term is -6
So common ratio r = second term/first term = -6/12= -1/2
The tenth term of the progression will be
⇒ ar¹⁰⁻¹ = ar⁹
⇒ 12(-1/2)⁹
⇒ -12(1/512)
⇒ -3/128
The sum to infinity = a / (1-r )
The sum to infinity = 12/(1 - 1/2)
The sum to infinity = 12 × 1/2
The sum to infinity = 6
Thus, the tenth term of the progression will be -3/128, and the sum to infinity will be 6.
