The length of the other two sides of triangle B are determined as:
9 cm and 12 cm.
How to Find the Length of the Sides of Similar Triangles?When solving for the length of the side of triangles that are are similar, note that their sides have lengths that are proportional to each other.
Thus, since triangles A and B are similar, it means they will have side corresponding side lengths that are proportional, therefore:
Let x represent the length of the longest side of triangle B and y represent the medium side.
Therefore, we have:
4/6 = 6/y
4y = 36
4y/4 = 36/4
y = 9 cm
4/6 = 8/x
4x = 48
x = 12 cm

Carly deposits money into a compound interest account in 2010. The equation P = 600(1.0375)
represents the amount of money in her account, P, after t years.
Determine how much money Carly has in her account in 2047. What was the growth rate?
How long does it take for Carly's account to reach $750? Round answer to the nearest tenth.
The compound interest is solved and the amount in her account in 2047 is given by A = $ 1315.46
Given data ,
To determine how much money Carly has in her account after 37 years, we need to substitute the value of t as 37 into the equation:
P = 600(1.0375)^t
P = 600(1.0375)^37
P ≈ 600(1.0375)^37 ≈ 600(2.19243) ≈ $ 1315.46
Therefore , Carly has approximately $1315.46 in her account after 37 years.
To calculate the growth rate, we need to find the rate of change between the initial and final amounts over the given time period.
Regarding how long it takes for Carly's account to reach $750, we'll assume you mean when the account reaches or exceeds $750. Let's set up the equation and solve for t:
750 = 600(1.0375)^t
Dividing both sides by 600, we get:
1.25 = 1.0375^t
Taking the logarithm of both sides (base 1.0375):
log(1.25) = t * log(1.0375)
t ≈ log(1.25) / log(1.0375) ≈ 8.5 years
Hence , it takes approximately 8.5 years for Carly's account to reach or exceed $750

The values of x and y are proportional. proportionality (k) and find the missing values. 2. UX x 6 15 9 y 42 200 d. X 14 y 21 6 15 3 7 8 Determine the constant of proportionality
Step-by-step explanation:
To determine the constant of proportionality (k) in a proportional relationship, we need to compare corresponding values of x and y and calculate the ratio between them.
Let's examine the given values:
2. UX: x 6 15 9 y 42 200
To find the constant of proportionality (k), we can take any pair of corresponding values and calculate their ratio. Let's choose the first pair: (6, 42).
k = y / x
k = 42 / 6
k = 7
So, the constant of proportionality (k) is 7.
Now, let's find the missing values for the second set of values:
d. X: 14 y: 21 6 15 3 7 8
Since we know the constant of proportionality is 7, we can calculate the missing values of y by multiplying each corresponding x value by 7.
Missing values for y:
- For x = 21, y = 21 * 7 = 147
- For x = 6, y = 6 * 7 = 42
- For x = 15, y = 15 * 7 = 105
- For x = 3, y = 3 * 7 = 21
- For x = 7, y = 7 * 7 = 49
- For x = 8, y = 8 * 7 = 56
Therefore, the missing values of y are: 147, 42, 105, 21, 49, and 56.
For the line that passes through the points A(5, 8, -2) and B(-1, 3, 5), find:
a. a vector equation.
b. parametric equations.
c. Symmetric equations
The symmetric equations for the line are:
(36x + 40y - 28z - 100) / 0 = (x-5) / -6 = (y-8) / -5 = (z+2) / 7
To find the parametric equations for the line passing through A(5, 8, -2) and B(-1, 3, 5), we can use the vector equation:
r = A + t(B-A)
where r is the position vector of any point on the line, t is a scalar parameter, and A and B are the given points. Substituting the values, we get:
r = (5, 8, -2) + t((-1)-5, 3-8, 5-(-2))
r = (5, 8, -2) + t(-6, -5, 7)
The parametric equations for the line are:
x = 5 - 6t
y = 8 - 5t
z = -2 + 7t
To find the symmetric equations, we can use the fact that any point on the line is equidistant from points A and B. Thus, the distance from a point (x, y, z) to A must be the same as the distance from the same point to B. Using the distance formula, we get:
√[(x-5)² + (y-8)² + (z+2)²] = √[(x+1)² + (y-3)² + (z-5)²]
Squaring both sides and simplifying, we get:
36x + 40y - 28z - 100 = 0

What value of x satisfies the equation −1.5x−2.7=20.1+4.5x
To solve for x in the equation −1.5x−2.7=20.1+4.5x, we need to isolate x on one side of the equation. We can do this by adding 1.5x to both sides of the equation and adding 2.7 to both sides of the equation, which gives us:
-1.5x - 2.7 + 1.5x = 20.1 + 4.5x + 1.5x
Simplifying the left side of the equation and combining like terms on the right side of the equation gives us:
-2.7 = 6x + 20.1
Subtracting 20.1 from both sides of the equation gives us:
-22.8 = 6x
Dividing both sides of the equation by 6 gives us:
x = -3.8
Therefore, the value of x that satisfies the equation is -3.8.

f(3) = 16
h(0) = -4
h(g(x)) = 3x + 5
g(y) = y + 3
f(x) - h(x) = x² - x + 5
How to solve function?A function relates input and output. In other words, a function is an expression that defines a relationship between one variable (the independent variable) and another variable(dependent variable).
Therefore, let's solve the function as follows:
f(x) = x² + 2x + 1
g(x) = x + 3
h(x) = 3x - 4
Therefore,
f(3) = (3)² + 2(3) + 1 = 9 + 6 + 1 = 16
h(0) = 3(0) - 4 = -4
h(g(x)) = 3(x + 3) - 4 = 3x + 9 - 4 = 3x + 5
g(y) = y + 3

If s5= -16.3804 and r=9/10,what is a₁?
The first term of GP is a₁ = -4.
Given that,
Sum of five terms of GP = s₅ = -16.3804
Common ratio = 9/10 which is less than 1
Number of terms = n = 5
We know that,
Sum of nth term of GP when common ration is less than 1,
s₅ = a₁(1-[tex]r^{n}[/tex])/(1-r)
Substituting the values,
⇒ -16.3804 = a₁(1-0.9⁵)/(1-0.9)
⇒ a₁ = -16.3804/4.0951
⇒ a₁ = -4
Hence, the value of a₁ is -4.

Apple juice costs $2.50 for 128 ounces. What is the price per ounce?
Answer: $0.0195
Step-by-step explanation: To find the price per ounce of apple juice, we need to divide the total cost by the number of ounces.
Price per ounce = Total cost / Number of ounces
Here, the total cost is $2.50 and the number of ounces is 128.
Price per ounce = $2.50 / 128 ounces
Price per ounce = $0.0195
Therefore, the price per ounce of apple juice is $0.0195, which is approximately 2 cents per ounce.
Answer: $0.0195 per ounce
Step-by-step explanation:
We will create a proportion to help us solve this question.
➜ To do this, we will set two fractions equal to each other with the dollar amount in the numerator and the ounce amount in the denominator.
[tex]\displaystyle \frac{\$2.50}{128\;ounces} =\frac{\$x}{1\;ounce}[/tex]
Cross-multiply:
128x = $2.50
Divide both sides of the equation by x:
