distance. How much longer will you be
on Highway 40 after you pay the foll?
Distance traveled after toll payment is 1.2 miles on highway 40.
What is Distance ?The distance may be calculated using a curved route. Displacement measurements can only be made along straight lines. Distance is path-dependent, meaning it varies depending on the direction followed. Displacement simply depends on the body's beginning and ending positions; it is independent of the route.
Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.
The size or extent of the displacement between two points is referred to as distance. Keep in mind that the distance between two points and the distance traveled between them are not the same. The entire length of the journey taken between two points is known as the distance traveled. Travel distance is not a vector.
Distance traveled before toll payment =3/5 miles on highway 40
Distance traveled after toll payment =2*3/5 = 6/5 =
1.2 miles on highway 40.

(cos11+sin11)/(cos 11 - sin 11)=tan 56
Notice that 56° = 45° + 11°. Then
tan(56°) = sin(56°) / cos(56°)
… = sin(45° + 11°) / cos(45° + 11°)
… = (sin(45°) cos(11°) + cos(45°) sin(11°)) / (cos(45°) cos(11°) - sin(45°) sin(11°))
Recall that sin(45°) = cos(45°) = 1/√2, so we can cancel each term involving 45° :
tan(56°) = (cos(11°) + sin(11°)) / (cos(11°) - sin(11°))
Solve the initial value problem where y′′+4y′−21 y=0, y(1)=1, y′(1)=0 . Use t as the independent variable.
Answer:
\(y = \frac{7}{10} e^{3(t - 1)} + \frac{3}{10}e^{-7(t - 1)}\)
Step-by-step explanation:
y′′ + 4y′ − 21y = 0
The auxiliary equation is given by
m² + 4m - 21 = 0
We solve this using the quadratic formula. So
\(m = \frac{-4 +/- \sqrt{4^{2} - 4 X 1 X (-21))} }{2 X 1}\\ = \frac{-4 +/- \sqrt{16 + 84} }{2}\\= \frac{-4 +/- \sqrt{100} }{2}\\= \frac{-4 +/- 10 }{2}\\= -2 +/- 5\\= -2 + 5 or -2 -5\\= 3 or -7\)
So, the solution of the equation is
\(y = Ae^{m_{1} t} + Be^{m_{2} t}\)
where m₁ = 3 and m₂ = -7.
So,
\(y = Ae^{3t} + Be^{-7t}\)
Also,
\(y' = 3Ae^{3t} - 7e^{-7t}\)
Since y(1) = 1 and y'(1) = 0, we substitute them into the equations above. So,
\(y(1) = Ae^{3X1} + Be^{-7X1}\\1 = Ae^{3} + Be^{-7}\\Ae^{3} + Be^{-7} = 1 (1)\)
\(y'(1) = 3Ae^{3X1} - 7Be^{-7X1}\\0 = 3Ae^{3} - 7Be^{-7}\\3Ae^{3} - 7Be^{-7} = 0 \\3Ae^{3} = 7Be^{-7}\\A = \frac{7}{3} Be^{-10}\)
Substituting A into (1) above, we have
\(\frac{7}{3}B e^{-10}e^{3} + Be^{-7} = 1 \\\frac{7}{3}B e^{-7} + Be^{-7} = 1\\\frac{10}{3}B e^{-7} = 1\\B = \frac{3}{10} e^{7}\)
Substituting B into A, we have
\(A = \frac{7}{3} \frac{3}{10} e^{7}e^{-10}\\A = \frac{7}{10} e^{-3}\)
Substituting A and B into y, we have
\(y = Ae^{3t} + Be^{-7t}\\y = \frac{7}{10} e^{-3}e^{3t} + \frac{3}{10} e^{7}e^{-7t}\\y = \frac{7}{10} e^{3(t - 1)} + \frac{3}{10}e^{-7(t - 1)}\)
So the solution to the differential equation is
\(y = \frac{7}{10} e^{3(t - 1)} + \frac{3}{10}e^{-7(t - 1)}\)

Loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.
What is a sound wave?When energy moves through a medium (such as air, water, or any other liquid or solid matter), it creates a pattern of disturbance known as a sound wave that propagates away from the sound source.
When an object vibrates, sound waves are produced that are similar to pressure waves, like when a phone rings.
Pitch, intensity, and timbre are three key components of the field of sound psychology or psychoacoustics. People can distinguish the harmonics of a complex periodic sound wave under certain conditions thanks to the way that humans perceive sound and music.
Thus, loudness, pitch, and timbre are the three psychological aspects of sound that are influenced by the physical properties of sound waves.

Please answer the question in the photo.
The equation is sometimes true. When x = 0, 1 or -1, then the equation is true. Otherwise, the equation is false.
====================================================
Explanation:
When it comes to something like "always true" all we need is one counter example to break that statement. Pick something like x = 64 and you'll find that the left hand side becomes
\(x^{1/3} = 64^{1/3} = \sqrt[3]{64} = \sqrt[3]{4^3} = 4\)
while the right hand side turns into
\(x^3 = 4^3 = 4*4*4 = 64\)
This means the original equation \(x^{1/3} = x^3\) updates to \(4 = 64\) after plugging in x = 4. We get a false statement making the original statement false when x = 4. So saying "\(x^{1/3} = x^3\) is always true" is not correct.
----------------------
The equation is only sometimes true for the x values 0, 1 and -1
Let's try x = 0
\(x^{1/3} = x^3\\\\0^{1/3} = 0^3\\\\0 = 0\)
we get a true statement confirming x = 0 as a solution
Trying x = 1 leads to
\(x^{1/3} = x^3\\\\(1)^{1/3} = 1^3\\\\1 = 1\)
also true. A similar situation happens with x = -1 as well, just that we have negatives this time.

A loan program that has a single ratio of 45% would allow a borrower with $65,000 in annual income and $490 in monthly consumer debt payments to qualify for what principal and interest payment on a home with escrow requirements of $360 monthly?
As a result, the borrower can qualify for a loan amount of $476,757.76, expression resulting in a monthly principal and interest payment of $1,587.50, assuming a monthly escrow requirement of $360.
what is expression ?In mathematics, an expression is a grouping of representations, digits, and huge corporations that resemble a clear relationship or regimen. An expression can be a real number, a transitory, or a combination of the two. Addition, subtraction, pervasiveness, division, and exponentiation are examples of mathematical operators. Expressions are common in arithmetic, mathematics, and geometry. They are used in mathematical formula representation, equation solution, and mathematical relationship simplification.
To solve this problem, we must use the loan program's single ratio, which is 45%. This is the maximum debt-to-income (DTI) ratio a borrower can have in order to qualify for the loan.
$65,000 divided by 12 months equals $5,416.67 per month
$5,416.67 divided by 45% equals $2,437.50 per month
$2,437.50 minus $360 equals $2,077.50 per month
$2,077.50 minus $490 equals $1,587.50 per month
This means that the borrower can afford a $1,587.50 monthly principal and interest payment.
Loan amount = (Monthly payment) / (Monthly interest rate)
The loan amount is ($1,587.50) divided by the loan term (0.00333)
The loan amount is $476,757.76.
As a result, the borrower can qualify for a loan amount of $476,757.76, resulting in a monthly principal and interest payment of $1,587.50, assuming a monthly escrow requirement of $360.

Answer:
5
Step-by-step explanation:
The mean represents an average of all the numbers, so we have \(\frac{sum-of-all-numbers}{total-amount-of-numbers}\). Although that may seem confusing, it's actually pretty easy.
We have a total of five numbers, which are 1, 6, 2, 7, and 9.
We add these numbers up to find the sum, so 1 + 6 + 2 + 7 + 9 = 25
So our final answer will be \(\frac{25}{5}\) which can be simplified to 5.
Find the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0)
The value of x that makes the line containing (1,2) and (5,3) perpendicular to the line containing (x,4) and (3,0) is x = 2.
To determine the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0), we need to find the slope of both lines and apply the concept of perpendicular lines.
The slope of a line can be found using the formula:
slope = (change in y) / (change in x)
For the line containing (1,2) and (5,3), the slope is:
slope1 = (3 - 2) / (5 - 1) = 1 / 4
To find the slope of the line containing (x,4) and (3,0), we use the same formula:
slope2 = (0 - 4) / (3 - x) = -4 / (3 - x)
Perpendicular lines have slopes that are negative reciprocals of each other. In other words, if the slope of one line is m, then the slope of a line perpendicular to it is -1/m.
So, we can set up the equation:
-1 / (1/4) = -4 / (3 - x)
Simplifying this equation:
-4 = -4 / (3 - x)
To remove the fraction, we can multiply both sides by (3 - x):
-4(3 - x) = -4
Expanding and simplifying:
-12 + 4x = -4
Adding 12 to both sides:
4x = 8
Dividing both sides by 4:
x = 2

\(5x - 2 + x = -20\\\\\text{Combine like terms:}\\\\5x + x - 2 = -20\\\\6x - 2 = -20\\\\\text{Add 2 to both sides:}\\\\6x - 2 + 2 = -20 + 2\\\\6x = -18\\\\\text{Divide both sides by 6:}\\\\6x / 6 = -18/6\\\\x = -3\)
Simplify (ab2 + 10 + a) – (6ab2 – 2ab + 8)
−5ab2+2ab+a+2
