Answer: The student should check if the author's article provides more facts or evidence than opinions.
What is the difference between facts and opinions? Facts provide real statements that have been proved with solid evidence by experts. Meanwhile, on the other hand, opinions are what people think. It is more like thinking than something with evidence. It hasn't or can't be proved. If it includes more facts then the author's claims are strong with solid evidence. If it includes more opinions then the author's claims are not strong, they are weak. Since it's only the author's point of view.

Which explains whether or not the function represents a
direct variation?
O This function represents a direct variation because it
passes through the origin and has a constant rate of
change of $5 per hour.
O This function represents a direct variation because it
has a positive, constant rate of change of $10 per
hour.
O This function does not represent a direct variation
because it does not represent the cost for 1 hour.
This function does not represent a direct variation
because the function rule for the cost is to add $10,
not multiply by a constant.
Answer:
(a) This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Step-by-step explanation:
The equation of direct variation is ...
y = kx
for some constant k. Here, we have x in hours and y in dollars. We can see if k is constant for the values given in the table.
__
constant of variationSolving the direct variation formula for k, we have ...
k = y/x
Using the table values, we can see if this is constant:
k = dollars/hour = 10/2 = 20/4 = 30/6 = 40/8 = 5
The "rate of change" is constant at $5 per hour.
The function represents direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Aleena cuts 3/8 part of ribbon for her project.then again she cuts 4/5 part of the remaining ribbon the next day.find the total length of the Ribbon ,if 6.5 m of ribbon still remain
The total length of the ribbon is 52 m.
Let x = the original length of the ribbonAleena initially cuts 3/8 of the ribbon, i.e. a length of (3/8)x.
How much is left?1 - (3/8)x = (5/8)x.
On the next day, she cuts 4/5 of the remaining ribbon.i.e. (4/5) * (5/8)x = (20/40)x = (1/2)x
How much of the ribbon has she now cut away?(3/8)x + (1/2)x = (3/8)x + (4/8)x = (7/8)x
That means 1 - (7/8)x = (1/8)x remains, and that is a length of 6.5 m.
We now need to determine the following:1/8 of what number is 6.5?
Let y = the unknown number.
(1/8)y = 6.5
Multiply both sides of the equation by 8 to clear the fraction.
y = 52 m

What is the triangle inequality theorem?The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,
[tex](a+b) > c\\(b+c) > a\\(c+a) > b[/tex]
Given the length of the two sides of the triangle, therefore, we can write the inequalities,
8 + 5 > x ⇒ 13 > x
8 + x > 5 ⇒ x > - 3
5 + x > 8 ⇒ x > 3
Now, as per the inequality the value of x can lie between 3 to 13, but as the side needs to be greatest, therefore, the value of x will be 12.

10 11
Answer:
The airplane reaches its maximum height of 74 feet in 14 seconds.
Step-by-step explanation:
The easiest thing to do here is to plug in the two numbers given in the answer choices. Finding the height at 14 seconds and the height after 74 seconds is straightforward from here.
h (14) = -(14-14)²+ 74
h (14) = 0 + 74
h (14) = 74
h (74) = -(74-14)² + 74
h (74) = -(60)² + 74
h (74) = -3600 + 74
h (74) = -3,526
Now, we know that a height of an airplane won't be negative, as the height below the ground cannot be reached.
because our equation includes -(t-14)², any number greater than 14 will be a larger negative than 0--setting the height to an impossible number.
{However, we add +74 feet, so our t-14 could be any number that is less than 74 when squared (after first subtracting 14 from the number). Numbers like 15, (resulting in subtracting 1 from 74), 16 (resulting in -4 from 74), 17 (74-9), 18 (74-16), 19 (74-25), 20 (74-36), 21 (74-49), 22 (74-64) are still above the minimum input}
{So, our t could be up to 22, and any number above this maximum limit, such as 23, result in a height of 0}
for example: -(23-14)² + 74
-(9)² = -81
-81 + 74 = -7
All numbers below 14, which would end in an eventual negative outcome [ -(x)² = negative if x < 0 ]
are greater than a t of 14.
-(13-14)² = -1
; showing that t = 14 is our maximum height
(remember that if you have -(x)² you get the negative version of x² [pemdas. the negative outside of the parenthesis is equivalent to multiplying the parenthesis by -1. (E)xponents comes before (M)ultiplication].)

monthly. After 2 years, she
withdrew all her money, and as an
early withdrawal penalty, she paid
back all the interest she made
during the first year. How much
money was Diana left with?
Th amount of money that Diana is left with is $8,430.23.
How much is Diana left with?The first step is to determine the interest earned in the first year and the total amount that was made in the 2 years.
The formula used to determine the future value with monthly compounding is:
P(1 + r)^( n x m)
Where:
P = present value r = periodic interest rate n = number of years m = frequency of compoundingTotal amount made in 2 years = $8000 x ( 1 + 5% / 12)^(12 x 2) = 8839.53
Interest earned in the first year = [ $8000 x ( 1 + 5% / 12)^(12) ] - 8000 = $409.29
Amount she is left with = 8839.53 - $409.29 = $8430.23

Kyles's monthly repayment on the television based on hire purchase agreement is R229
What is the monthly repayment?The monthly repayment is the amount paid monthly with interest on a particular loan or to recover from debt.
From the given information:
The price of the television = R5600Initial deposit = 15% of cash price = 0.15 × 5600 = 840Thus
principal amount left to be repaid = 5600 - 840 = 4760

Write your answer in this form: (X₁,Y₁), (X2,₂).
If necessary, round to the nearest hundredth.

Answer: (-12, 0) and (6, 0)
Step-by-step explanation:
The equation of the parabola is of the form
[tex]y=a(x+3)^2 + 405[/tex]. To find a, we can substitute in the coordinates (0,360).
[tex]360=a(0+3)^2 + 405\\\\360=9a+405\\\\-45=9a\\\\a=-5[/tex]
So, the equation is [tex]y=-5(x+3)^2 + 405[/tex]. Setting this equal to 0,
[tex]-5(x+3)^2 + 405=0\\\\5(x+3)^2 = 405\\\\(x+3)^2 = 81\\x+3=\pm 9\\\\x=-12, 6[/tex]

At a certain college, 49% of the students are female, and 21% of the students major in civil engineering. Furthermore, 8% of the students both are female and major in civil engineering.
The probability that a student is a female or major in civil engineering is 62%
How to determine the probability?Let A represent Female and B represents civil engineering.
So, we have:
P(A) = 49%
P(B) = 21%
P(A and B) = 8%
The required probability is calculated as:
P(A or B) = P(A) + P(B) - P(A and B)
This gives
P(A or B) = 49% + 21% - 8%
Evaluate
P(A or B) = 62%
Hence, the probability that a student is a female or major in civil engineering is 62%

Marco's living room is 4 meters wide and 6 meters long. He wants to install white carpet that costs $8.91 per square meter. How much will it cost to buy enough carpet for the living room?
Answer:
$213.84
Step-by-step explanation:
Think of a rectangle. In the case the length is 6 meters and the width is for meters. To be able to find the area of this rectangle, you need to multiply the length by the width. 6 multiplied by 4 is 24. In the equation it tells you that 1 square meter is $8.91, so now you are trying to figure how much 24 square meters would cost. To figure this out, you will need to multiple 24 by $8.91 giving you $213.84.
