<1 =46<2=164<3= 46<5= 46<6= 164<7= 46<8= 134What are Parallel lines?The fundamental characteristics listed below make it simple to recognise parallel lines.
Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.Given:
<4 = 134
So, <4 = <2 = 134 (Vertical opposite angle)
<4= <8= 134 (Corresponding Angle)
<1 + <4 = 180 (Linear Pair)
<1 = 180-134
<1 = 46
<1 = <3= 46 (Vertical opposite angle)
<2= <6= 164 (Corresponding Angle)
<3= <7 (Corresponding Angle)
<1= <5 (Corresponding Angle)

in triangle ABC,m<A=31 degrees, m<B=59 degrees, and m<c=90 degrees. which side is the hypotenuse: AB,BC, or CA?
help!!!
Answers
In a right triangle, the side opposite the right angle (90 degrees) is always the hypotenuse. In triangle ABC, angle C is 90 degrees. Therefore, side CA is the hypotenuse of the triangle.
In a right triangle, one of the angles measures 90 degrees, which is known as the right angle. The side opposite this right angle is called the hypotenuse. It is the longest side in a right triangle and is directly across from the right angle.
In triangle ABC, it is given that angle C measures 90 degrees (m<C = 90 degrees). This means that side CA is opposite the right angle and, therefore, is the hypotenuse of the triangle.
To summarize, in triangle ABC, side CA is the hypotenuse since it is opposite the right angle.

The reference angle is ?
The opposite side is 21

The regular price of a scooter is $65.50. It is on sale for $52.40. What is the percent
decrease from the regular price to the sale price of the scooter?
Answers
Answer:
20%
Step-by-step explanation:
First we find the actual dollar amount of the discount.
$65.50 - $52.40 = $13.10
Now we need to find what percent of $65.50 is $13.10.
To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.
percent = part/whole * 100%
percent = $13.10/$65.50 * 100% = 20%

find the point on the line y = 5x 2 that is closest to the origin. (x, y) =
Answers
The point on the line y = 5x + 2 that is closest to the origin is approximately (0.3448, 1.7931), which is (x, y) when x = 10/29 and y = 52/29.
The equation of the line is y = 5x + 2, and the point on the line closest to the origin is (x, y).
To find the distance from the origin to the point (x, y), use the distance formula:
d = √(x² + y²)
To minimize the distance, we can minimize the square of the distance:
d² = x² + y²
Now, we need to use calculus to find the minimum value of d² subject to the constraint that the point (x, y) lies on the line y = 5x + 2.
This is a constrained optimization problem. Using Lagrange multipliers, we can set up the following system of equations:
2x = λ
5x + 2 = λ5
Solving this system, we get:
x = 10/29, y = 52/29
So, the point on the line y = 5x + 2 that is closest to the origin is approximately (0.3448, 1.7931), which is (x, y) when x = 10/29 and y = 52/29.

if ∑an and ∑bn are both convergent series with positive terms, then ∑anbn is convergent.T/F
Answers
If the series ∑an and ∑bn are both convergent series with positive terms, then the series ∑anbn is also convergent.
This can be proven using the Comparison Test for series convergence. Since an and bn are both positive terms, we can compare the series ∑anbn with the series ∑an∑bn.
If ∑an and ∑bn are both convergent, then their respective partial sums are bounded. Let's denote the partial sums of ∑an as Sn and the partial sums of ∑bn as Tn.
Then, we have:
0 ≤ Sn ≤ M1 for all n (Sn is bounded)
0 ≤ Tn ≤ M2 for all n (Tn is bounded)
Now, let's consider the partial sums of the series ∑an∑bn:
Pn = a1(T1) + a2(T2) + ... + an(Tn)
Since each term of the series ∑anbn is positive, we can see that each term of Pn is the product of a positive term from ∑an and a positive term from ∑bn.
Using the properties of the partial sums, we have:
0 ≤ Pn ≤ (M1)(Tn) ≤ (M1)(M2)
Hence, if ∑an and ∑bn are both convergent series with positive terms, then ∑anbn is also convergent.
Therefore, the given statement is True.

What value of C will make the following system a dependent system (one in which the lines coincides)15x +20y= -106x + 8y= c
Answers
ANSWER
C = -4
EXPLANATION
Given:
15x +20y= -10
6x + 8y= c
Thus we have:
a1 = 15x, b1 = 20y, c1 = -10
and
a2 = 6x, b2 = 8y, c2 = c
The condition now is:
\(\frac{a_1}{a_2}\text{ = }\frac{b_1}{b_2}\text{ = }\frac{c_1}{c_2}\)i.e:
\(\frac{15x}{6x}=\frac{20y}{8y}\text{ = }\frac{-10}{c}\)Determine c using the x
\(\begin{gathered} \frac{15x}{6x}=\frac{-10}{c} \\ \frac{5}{2}\text{ = }\frac{-10}{c} \\ 5c\text{ = -20} \\ c\text{ = -}\frac{20}{5} \\ c\text{ = -4} \end{gathered}\)Determine c using the y
\(\begin{gathered} \frac{20y}{8y}\text{ = }\frac{-10}{c} \\ \frac{10}{4}\text{ = }\frac{-10}{c} \\ 10c\text{ = -40} \\ c\text{ = }\frac{-40}{10} \\ c\text{ = -4} \end{gathered}\)Hence, the value of C that will make the systems a dependent system is -4.

I need this ASAP! When David was asked how old he was, he said: "I'm three times younger than my dad, but twice as old as Rebecca." Then little Rebecca ran up to him and declared "I am 30 years younger than my dad." How old is David?
Answers
Answer:
David is 12 years old.
Step-by-step explanation:
Let r = Rebecca's age
Let d = David's age
let p = Dad's age
David is 3 times as younger than his dad:
d = \(\frac{p}{3}\)
David is 2 times older than Rebecca:
d = 2r
Rebecca is 30 years younger than the dad:
r = p-30
All three equations can be solved by a system
2r = \(\frac{p}{3}\)
r = p-30
multiplying r = p-30 by negative 2 and adding it to 2r = \(\frac{p}{3}\)
0 = (-2p + p/3) + 60
multiplying new equation by 3
0 = (-6p + p) + 180
5p = 180
p = 36
d = 36/3 = 12

Let f be the function defined by f(x)= 1/3 x^3 - 4x^2 - 9x + 5. On which of the following intervals is the graph of f both decreasing and concave down?
Answers
The graph of f is both decreasing and concave down on the interval (9, infinity). Therefore, the correct answer is (D).
To determine where the graph of f is both decreasing and concave down, we need to analyze the first and second derivatives of f.
First derivative:
f'(x) = x² - 8x - 9
Second derivative:
f''(x) = 2x - 8
The graph of f is decreasing when f'(x) < 0, and concave down when f''(x) < 0.
To find where the graph of f is both decreasing and concave down, we need to look for where f'(x) < 0 and f''(x) < 0 simultaneously.
f'(x) < 0 when x < -1 or x > 9.
f''(x) < 0 when x < 4.
Therefore, the graph of f is both decreasing and concave down on the interval (9, infinity).

A bee flies at 10 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 10 minutes, and then flies directly back to the hive at 6 feet per second. It is away from the hive for a total of 12 minutes. A. What equation can you use to find the distance of the flowerbed from the hive? B. How far is the flowerbed from the hive?
Answers
Answer:
d/10 + 600 + d/6 = 720
450 fts
Step-by-step explanation:
Given that:
Speed from hive to flowerbed = 10 ft/s
Time used in flowerbed = 10 minutes
Speed from flowerbed to hive = 6ft/s
Total time at which bee is away from hive = 12 minutes
Equation to find distance of flowerbed from hive :
Let distance from hive to flowerbed = d
Time taken = distance / speed
Time taken from hive to flowerbed = d/ 10
Time used in flowerbed = 10 minutes = (10 * 60) = 600 seconds
Time taken from flowerbed to hive = d/6
Total time away from hive = 12 mins = (12 * 60) = 720 seconds
A. What equation can you use to find the distance of the flowerbed from the hive?
Distance can be obtained from the formula :
d/10 + 600 + d/6 = 720
B. How far is the flowerbed from the hive?
d/10 + 600 + d/6 = 720
Take L. C. M of 10 and 6 = 30
(3d + 18000 + 5d) = 21600
8d + 18000 = 21600
8d = 21600 - 18000
8d = 3600
d = 3600/8
d = 450
Distance of flowerbed from hive = 450 fts
