Two lines m annd l are perpendicular to lines pand n respectively. If n amd p intersect , proove l and m also intersect .
Answer:
See below
Step-by-step explanation:
Since lines n and p intersect, they must have different slopes. Lets say they have slopes 2 and 4, as an example. They will intersect. Lines m and l are perpendicular to n and p, so their slopes will be the negative inverse of 2 and 4. That gives them slopes of -(1/2) and -(1/4). These slopes are different, so they will intersect.
The attached graph illustrates this intersection with lines having the above slopes. Lines m and l intersect at (-1,1) in this example. Lines m and l also intersect, off the graph at the top left.
2. Ciara needs a $12,000 loan to purchase a car.
For which loan option will she pay the least
interest? Assume all rates are annual simple
interest.
A. 48-month loan; 5% rate
B. 60-month loan; 4.5% rate
C. 66-month loan; 3.75% rate
D. 72-month loan; 4% rate
Answer: To find out which loan option will have the least interest, you need to calculate the interest amount for each option. You can do this by using the formula:
Interest = Principal x Interest Rate x Time (in years)
For option A, the interest amount would be:
Interest = $12,000 x 0.05 x (48/12) = $2,400
For option B, the interest amount would be:
Interest = $12,000 x 0.045 x (60/12) = $3,000
For option C, the interest amount would be:
Interest = $12,000 x 0.0375 x (66/12) = $2,970
For option D, the interest amount would be:
Interest = $12,000 x 0.04 x (72/12) = $3,840
As we can see the lowest interest amount is option C which is $2,970. Thus Ciara will pay the least interest if she chooses option C.

Is it possible to draw a triangle with sides of lengths 2cm 3cm and 7 cm?
It is not possible to construct a triangle whose sides are 2 cm 3 cm and 7 cm because the sum of two sides(2 cm and 3 cm) are smaller than third sides(7 cm).
In the given question, we have to check that it is possible to construct a triangle whose sides are 2 cm 3 cm and 7 cm.
To check whether the given sides can make a triangle or not, we have to check that the sum of two sides always grater than the third side.
To check this we firstly add the 2 and 3
2 + 3 < 7
5 > 7
Now we add 2 and 7
2 + 7 > 3
9 > 3
Now we add 3 and 7
7 + 3 > 2

South of the starting point is the plane after 60 minutes?
What is the plane's distance from its starting point at that time?
The distance flown by the plane East of the starting point is (60 minutes * 500 km/h * cos(120°))/60 minutes/hour = 250 * cos(120°) km.
What is the Pythagorean theorem in plain English?
Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides. The Perpendicular, Base, and Hypotenuse are the names of the three sides of this triangle.
The distance flown by the plane South of the starting point is (60 minutes * 500 km/h * sin(120°))/60 minutes/hour = 250 * sin(120°) km.
To find the distance of the plane from the starting point, we need to use the Pythagorean theorem.
The distance would be √((250 * cos(120°))^2 + (250 * sin(120°))^2) = √(62,500 + 62,500) = √125,000 = approximately 111.8 km

Using trigonometric ratios, tree is leaning 106.1°-90° = 16.1° away from the vertical.
Pythagorean identities, reciprocal identities, sum and difference identities, double angle and half-angle identities are the main trigonometric identities. We must apply the sine rule and the cosine rule to the non-right-angled triangles.

3.5%. He plans to deposit an additional $200 each year, just after the
interest is compounded. What will his balance be after 16 years? (round to
the penny)
Dante deposited $5,000 into an account with an annual interest rate of
3.5%. He plans to deposit an additional $200 each year, just after the
interest is compounded. His balance will be $9,838.44 after 16 years.
What do you mean by annual interest rate?It displays the actual percentage rate of interest owed on any outstanding debts, including credit card debt and loans.
Because it takes compounding effects into account, the effective annual interest rate is the real interest rate on an investment or loan. The rate increases as the compounding periods get more frequent. Advertisements for loans or savings accounts may include both the nominal interest rate and the effective yearly interest rate. The rate that should be used to compare loan and investment rates of return is the effective annual interest rate.
We can substitute the known values into the formula and calculate the final balance:
A = $5,000 (1 + 0.035)¹⁶
We can calculate the final balance by using a calculator, or we can use the formula of compound interest:
A = P(1 + r/n)ˣ
where, A= Amount
P= Principle($5,000 )
x= Time(16 years)
n= Rate(3.5%)
A = $5,000 (1 + 0.035/1)¹⁶
Now we can add the $200 deposit each year for 16 years:
A = $5,000 (1 + 0.035)¹⁶ + $200 × 16
A = $9,838.44
Dante's balance will be $9,838

The formula of substitution propertyThis is usually expressed as:
If a = b, then a[x/y] = b[x/y]The substitution property states that if two expressions are equal, then they remain equal when the same values are substituted into them. This means that if one expression is equal to another, then the same value can be swapped in for any of the variables within them and the equality will still hold.
For example, if we have the equation 4x + 7 = 11, then we can swap in any value for x and the equation will still be true. This is because the substitution property allows us to make a substitution for any of the variables and the equation will remain true.

For example, 5, -3, and 0 are all integers.A mixed number is a combination of an integer and a fraction, such as 3 ½.A proper fraction is a fraction where the numerator (the number on top) is less than the denominator (the number on the bottom). For example, 3/4 is a proper fraction because 3 is less than 4. Improper fractions, on the other hand, have a numerator that is greater than the denominator, such as 7/4.In mathematics, integers are used to represent whole numbers and countable objects, while fractions are used to represent parts of a whole. Mixed numbers are a combination of both, used to represent a value that is between two integers. For example, if you were cooking a recipe that called for two and a half cups of flour, you would use a mixed number to represent this value.Proper fractions are useful for representing ratios or for dividing a whole into equal parts. For example, when dividing a cake into four equal parts, each part would be represented by a proper fraction, such as 1/4 or 2/4.Integers, mixed numbers, and proper fractions are all useful for representing different kinds of values and for performing calculations in mathematics.To learn more about mixed number refer to:

Answer:

Step-by-step explanation:
For the passenger to be correct, the two ratios should equal each other.
[tex]\frac{156}{34}[/tex] = [tex]\frac{39}{9}[/tex] Multiply both sides by 34 and 9
[tex]\frac{(34)(9)}{1}[/tex] x [tex]\frac{156}{34}[/tex] = [tex]\frac{(34)(9)}{1}[/tex] x [tex]\frac{39}{9}[/tex] On the left side of the equation, the 34's cancel each other out. On the right side of the equation, the 9's cancel out. That leaves us with:
(9)(156) = (340)(39)
1404 = 13260
These numbers do not equal each other so the ratios are not equal.
