Each side of a square is increased 6 inches. When this happens, the area is multiplied by 9. How many inches in the side of the original square?
Please explain the answer, words confuse me :
Answers
Answer:
x = 3 inches
Step-by-step explanation:
Let x = the side of the original square, so the area is x²
After increasing, the side becomes x + 6. so the area becomes (x + 6)²
The area is multiplied by 9 means
(x + 6)² = 9 * x²
Take a square root, get
x + 6 = 3 * x
2x = 6
x = 3 inches
Let L represent the side length of the original square.
Note that:
L² = A(L + 6)² = 9A1. Square root both sides:
(L + 6)² = 9 x L²=> √(L + 6)² = √9 x L²2. Simplify the RHS:
=> L + 6 = 3 x L=> L + 6 = 3L3. Subtract L from each side.
=> 6 = 2L4. Divide 2 both sides.
=> L = 3 inchesDouble check:Area of square with 3 inches as side length: 3² = 9 in²Area of square with 9 inches as side length: 9² = 81 in²=> 81 ÷ 9 = 9 (True)
This shows that the area of the original square is 9 times smaller than the increased square.

What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

A person who has owned a Roth IRA for five years may withdraw money from the account to buy their first home. The individual has to meet certain requirements and can't withdraw more than $10,000 per person.
A Roth IRA is a type of individual retirement account that allows for tax-free withdrawals of contributions at any time, without penalty or taxes. After five years of ownership, a person who has a Roth IRA may withdraw money from the account to buy their first home. This withdrawal is known as a "first-time homebuyer distribution."
However, there are certain rules and limitations to be aware of when withdrawing money from a Roth IRA for a first home purchase. The individual must be a first-time homebuyer, defined as someone who has not owned a home in the past two years. Additionally, the maximum amount that can be withdrawn for a first home purchase is $10,000 per person.
It's important to note that while contributions to a Roth IRA can be withdrawn tax-free and without penalty, earnings on those contributions may be subject to taxes and penalties if withdrawn before age 59 and a half.

g If a snowball melts so that its surface area decreases at a rate of 2 cm2/min, find the rate at which the diameter decreases when the diameter is 8 cm.
Answers
Answer:
0.0398cm/s
Step-by-step explanation:
The snow ball is spherical in nature.
Total surface area of the spherical ball = 4πr²
= 4π(d/2)²
= 4π(d²/4)
= πd²
S = πd²
dS/dt = dS/dd • dd/dt
dS/dt = 2πd•dd/dt
Given
dS/dt = 2cm²/min
d = 8cm
Substitute and get dd/dt
2 = 2π(8) •dd/dt
2 = 16π•dd/dt
dd/dt = 2/16π
dd/dt = 1/8π
dd/dt = 1/8(3.14)
dd/dt = 1/25.12
dd/dt = 0.0398cm/s
Hence the rate at which the diameter is decreasing is 0.0398cm/s

A = \(\frac{1}{2}h(b_{1} +b_{2} )\)
If A = 136 when \(b_{1}\) = 7 and h = 16, find \(b_{2}\)
Givens:We are given the equation that we are working with:
A = \(\frac{1}{2}h(b_{1} +b_{2} )\)
We are given certain values that the variables, in this case, are equal to:
A = 136
\(b_{1}\) = 7
h = 16
Steps:Substitute the given variables in the given equation for the corresponding numbers:
A = \(\frac{1}{2}h(b_{1} +b_{2} )\)
136 = \(\frac{1}{2}\) * 16 (7 + \(b_{2}\))
We know all the values in the equation except \(b_{2}\). In order to find \(b_{2}\) we must isolate it on one side of the equation
136 = 8 (7 + \(b_{2}\))
\(\frac{136}{8}\) = \(\frac{8 (7 + b_{2}) }{8}\)
17 = 7 + \(b_{2}\)
17 - 7 = 7 - 7 + \(b_{2}\)
10 = \(b_{2}\)
Check:If \(b_{2}\) is equal to 10 then if we plug it back into the given equation both sides of the equation should equal each other. Remember to use PEMDAS
136 = \(\frac{1}{2}\) * 16 (7 + \(b_{2}\))
136 = \(\frac{1}{2}\) * 16 (7 + 10)
136 = \(\frac{1}{2}\) * 16 (17)
136 = 8 (17)
136 = 136
\(b_{2}\) = 10
Use linear approximation, i.e. the tangent line, to approximate 3√ 125.2 as follows: Let f(x)=√x. The equation of the tangent line to f(x) at x = 125 can be written in the form
y=mx+b
Answers
Using linear approximation, the expression √125.2 can be approximated as approximately 10.02.
How to find linear approximation?To find the equation of the tangent line to the function f(x) = √x at x = 125, determine the slope (m) and the y-intercept (b) of the tangent line.
First, find the slope (m) using the derivative of the function f(x) = √x:
f'(x) = 1 / (2√x)
Evaluate the derivative at x = 125:
f'(125) = 1 / (2√125) = 1 / (2 × 5) = 1/10
Now, find the y-coordinate of the point on the function f(x) at x = 125:
f(125) = √125 = 5
So, the tangent line at x = 125 passes through the point (125, 5) and has a slope of 1/10.
Using the point-slope form of a linear equation, the equation of the tangent line can be written as:
y - 5 = (1/10)(x - 125)
To simplify, multiply through by 10:
10y - 50 = x - 125
Rearranging the equation, express it in the form y = mx + b:
y = (1/10)x - 75/10 + 5
Simplifying further:
y = (1/10)x - 75/10 + 50/10
Combining the terms:
y = (1/10)x - 25/10
Therefore, the equation of the tangent line to f(x) = √x at x = 125 is y = (1/10)x - 25/10.
Now, use this tangent line to approximate the value of √125.2:
Substitute x = 125.2 into the equation:
y = (1/10)(125.2) - 25/10
y = 12.52 - 2.5
y ≈ 10.02
So, using linear approximation, approximate √125.2 as approximately 10.02.

Candice is preparing for her final exam in Statistics. She knows she needs an 62 out of 100 to earn an A overall in the course. Her instructor provided the following information to the students. On the final, 200 students have taken it with a mean score of 54 and a standard deviation of 6. Assume the distribution of scores is bell-shaped. Calculate to see if a score of 62 is within one standard deviation of the mean.
Answers
Answer:
A score of 62 is not within one standard deviation of the mean.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean score of 54 and a standard deviation of 6.
This means that \(\mu = 54, \sigma = 6\)
Calculate to see if a score of 62 is within one standard deviation of the mean.
Is Z between -1 and 1 when X = 62?
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{62 - 54}{6}\)
\(Z = 1.33\)
So a score of 62 is not within one standard deviation of the mean.

What transformation that will change the orientation of a figure but not the orientation of the vertices?
Answers
Answer:
Step-by-step explanation:
A transformation that changes the orientation of a figure but not the orientation of the vertices is called a "reflection."
A reflection is a transformation that flips a figure over a line, called the "line of reflection." The line of reflection can be a line on a coordinate plane, or it can be a line in the space of the figure. The transformed figure, or the image, is a mirror image of the original figure, with respect to the line of reflection. The line of reflection is the perpendicular bisector of the line connecting any two non-adjacent vertices of the figure, then the figure's orientation remains unchanged but it's flipped over that line.
For example, if you reflect a square over its diagonal line, the square will be flipped but its vertices will still be in the same order, so the orientation won't change.

Answers
The value of the vehicle 13 years after purchase is $13,695.24.
What is exponential decay?
Exponential decay is a mathematical process in which a quantity decreases over time in a manner proportional to its current value. This means that the rate of decay is proportional to the amount of the substance remaining, and as the amount of the substance decreases, the rate of decay also decreases.
We can use the formula for exponential decay to find the approximate value of the vehicle 13 years after the purchase:
\($V = V_0 e^{-rt}$\)
where V0 is the initial value of the vehicle, r is the annual depreciation rate (as a decimal), t is the number of years since purchase, and e is the mathematical constant approximately equal to 2.71828.
Substituting the given values, we get:
\($V \approx 29800 e^{-0.06*13}$\)
\($V \approx 29800 e^{-0.78}$\)
V ≈ 29800 x 0.4593
V ≈ 13695.24
Therefore, the approximate value of the vehicle 13 years after purchase is $13,695.24.
