[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] - 7
Step-by-step explanation:
Note the common difference d between consecutive terms in the sequence, that is
d = - 35 - (- 28) = - 42 - (- 35) = - 49 - (- 42) = - 7
Thus to obtain a term in the sequence subtract 7 from the previous term
[tex]a_{n+1[/tex] = [tex]a_{n}[/tex] - 7 with a₁ = - 28

After the translation, rotation and reflection position of the image may differ but the side lengths, angle, orientation remains the same, so that the congruence is maintained, but in dilation the size of the image may get enlarged or reduced, so that congruence is not there.
Parallelograms are congruent when
Reflect across the y- axis and then translate 1 unit left.
Reflect across the y- axis then rotate 45° counterclockwise.
Translate 4 units up then rotate 180° counterclockwise
Parallelograms are non-congruent when
Translate 5 units right then dilate by a factor of 2
Rotate 90° clockwise then dilate by a factor of 6
Dilate by a factor of 3 then reflect across the x- axis
$800 is deposited in an account
that pays 9% annual interest,
compounded annually. Find the
balance after four years.
Answer:
The balance after four years is $1129.27
Step-by-step explanation:
The formula for compound interest, including principal sum, is [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
A = the future value of the investment/loan, including interestP = the principal investment amount (the initial deposit or loan amount)r = the annual interest rate (decimal)n = the number of times that interest is compounded per unit tt = the time the money is invested or borrowed for∵ $800 is deposited in an account
∴ P = 800
∵ The account pays 9% annual interest
∴ r = 9% = 9 ÷ 100 = 0.09
∵ The interest is compounded annually
∴ n = 1
∵ The time is 4 years
∴ t = 4
- Substitute the values of P, r, n, and t in the formula above
∵ [tex]A=800(1+\frac{0.09}{1})^{(1)(4)}[/tex]
∴ [tex]A=800(1.09)^{4}[/tex]
∴ A = 1129.265
∴ The balance after four years is $1129.27

Elle earned $45 last month babysitting. This month she earned $35. What is the percent decrease?
Answer:
10percent
Step-by-step explanation:
I think
Elle experienced a 22.22% decrease in earnings from babysitting, from $45 to $35. This is calculated by finding the difference between the two amounts, dividing by the original amount, and then multiplying by 100 to convert to a percentage.
Explanation:Elle's decrease in earnings can be calculated using the formula for calculating the percentage decrease, which is [(Original value - New value)/(Original value)] * 100.
In Elle's case, the original value is $45 (the amount she earned last month), and the new value is $35 (the amount she earned this month). So, follow the formula:
Subtract the new value from the original value: $45 - $35 = $10Divide the decrease by the original value: $10/$45 = 0.2222Multiply the result by 100 to convert it to a percentage: 0.2222 * 100 = 22.22%So, Elle experienced a 22.22% decrease in her earnings from babysitting.

In the isosceles triangle ABC, we have AB=AC=4. The altitude from B meets AC at H. If AH=3(HC) then determine BC.
In isosceles triangle ABC with AB=AC=4, and AH=3HC, the length of BC is [tex]\( \frac{4\sqrt{5}}{5} \)[/tex] units, determined using the Pythagorean Theorem and the given relationship between AH and HC.
In isosceles triangle ABC, let BH be the altitude from B to side AC. Given AB = AC = 4 and AH = [tex]3 \cdot[/tex] HC, we can use the Pythagorean Theorem in right triangle ABH:
[tex]\[ BH^2 + AH^2 = AB^2 \][/tex]
Substitute the given values:
[tex]\[ BH^2 + (3HC)^2 = 4^2 \][/tex]
Simplify:
[tex]\[ BH^2 + 9HC^2 = 16 \][/tex]
Since BH = HC in an isosceles triangle, substitute BH with HC:
[tex]\[ HC^2 + 9HC^2 = 16 \][/tex]
Combine like terms:
[tex]\[ 10HC^2 = 16 \][/tex]
Solve for HC :
[tex]\[ HC^2 = \frac{8}{5} \][/tex]
Now, use the Pythagorean Theorem in right triangle BHC:
[tex]\[ BC^2 = BH^2 + HC^2 \][/tex]
Substitute the known values:
[tex]\[ BC^2 = HC^2 + HC^2 \]\[ BC^2 = 2HC^2 \]\[ BC^2 = 2 \cdot \frac{8}{5} \]\[ BC^2 = \frac{16}{5} \][/tex]
Therefore, BC is the square root of [tex]\( \frac{16}{5} \)[/tex], which simplifies to [tex]\( \frac{4}{\sqrt{5}} \)[/tex] or [tex]\( \frac{4\sqrt{5}}{5} \)[/tex].
The length of BC in an isosceles triangle with sides AB=AC=4 and altitude BH, where AH=3(HC), is 2√2 units.
Explanation:To determine the length of BC in an isosceles triangle ABC with sides AB=AC=4 and altitude BH, where AH=3(HC), we can use the properties of similar triangles and the Pythagorean theorem.
Since the triangle is isosceles, the altitude BH will bisect the base AC at H, creating two right triangles ABH and CBH. We know that AH=3(HC), which can be expressed as AH=3x and HC=x for some value x. Therefore, AC = AH + HC = 3x + x = 4x.
Using the Pythagorean theorem (a² + b² = c²), in triangle ABH, we get:
AH² + BH² = AB²(3x)² + BH² = 4²9x² + BH² = 16And in triangle HBC, we have:
HC² + BH² = BC²x² + BH² = BC²Since we want to find BC, we first solve for BH from the first right triangle:
BH² = 16 - 9x²Substitute BH² into the second equation:
x² + (16 - 9x²) = BC²-8x² + 16 = BC²To find x, we use AC = 4x = 4, thus x = 1. Substituting x into the equation for BC, we get:
-8(1)² + 16 = BC²-8 + 16 = BC²BC² = 8BC = √8BC = 2√2 unitsThe width of a rectangle is 2m less than the length. The area is 48m squared. Find the dimensions.
Length of the rectangle is 8m and width is 6m
Step-by-step explanation:
Step 1: Given area of the rectangle = 48m². Let the length be x, then the width is x - 2. Find the dimensions using the area of the rectangle = length × breadth48 = x (x - 2)
48 = x² - 2x
x² - 2x - 48 = 0
x² - 8x + 6x - 48 = 0
x(x - 8) + 6(x - 8) = 0
(x + 6)(x - 8) = 0
x = -6, 8 (neglecting the negative value)
∴ Length of the rectangle = 8m
∴ Width of the rectangle = 8 - 2 = 6m

m∠FGL = (x + 12)°
m∠LGH = (16x)°
A) 3
B) 5
C) 6
D) 8
Option D:
x = 8
Solution:
Given data:
m∠FGH = 148° , m∠FGL = (x + 12)° and m∠LGH = (16x)°
To find the value of x:
m∠FGL + m∠LGH = m∠FGH
⇒ (x + 12)° + (16x)° = 148°
⇒ x° + 12° + 16x° = 148°
⇒ 17x° + 12° = 148°
Subtract 12° from both sides of the equation.
⇒ 17x° = 136°
Divide by 17 on both sides, we get
⇒ x° = 8°
⇒ x = 8

A new car is Purchased for 16200 dollars. The value of the car depreciates at 14.25% per year. What will the value of the car be, to the nearest cent,after 6 years?
Answer:
6,440.5
Step-by-step explanation:
So the car starts at 16,200. For the first part of the equation it's 16,200 × x raised to the y. X in this equation would be 1-.1425 = 0.8575. 16,200×(.8575)^y. Y is the number of years after you purchased the car. So, 16,200×(.8575)^6 and that equals 6,440.5

Triangles ABC and DEF are (similar or not similar)
ΔABC and ΔDEF are similar by AAA similarity.
Solution:
Sum of the interior angles = 180°
In triangle ABC,
60° + 60° + m∠C = 180°
120° +m∠C = 180°
Subtract 120° from both sides, we get
m∠C = 60°
In triangle DEF,
60° + 60° + m∠F = 180°
120° +m∠F = 180°
Subtract 120° from both sides, we get
m∠F = 60°
Consider ΔABC and ΔDEF,
∠A ≅ ∠D
∠B ≅ ∠E
∠C ≅ ∠F
Therefore by AAA similarity ΔABC ≅ ΔDEF.
ΔABC and ΔDEF are similar triangles.
