Which of these tables represent a nonlinear function?
Answer:
(3)
Step-by-step explanation:
Analise the slope m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(1). (19-20)/(18-17) = - 1 ; (18-19)/(19-18) = - 1 ; (17-18)/(20-19) = - 1 ⇒ table represents a linear function.
(2). (-17+16)/(18-17) = - 1 ; (-18+17)/(19-18) = - 1 ⇒ table represents a linear function.
(3). (17-16)/(18-17) = 1 ; (19-17)/(19-18) = 2 ⇒ table represents a nonlinear function.

what is the LCM of 80 and 60
Answer:
240
Step-by-step explanation:
Answer:
240
Step-by-step explanation:
What I do is I first multiply the two numbers...
(60 * 80 = 240)
From there I try and find if there is any number lower than the product of these two numbers... if there isn't... then the product is the LCM
Since the only factor between 80 and 240 is 160... that is the only other possible answer... since 160 is not a multiple of 60... the answer can only be 240.
I hope this helps and wasn't too confusing:)
The manager of a garden store decides to hold a Buy 3, Get 1 Free sale on vegetable plants. The sale is held for one week and a total of 636
vegetable plants were sold (not including the ones given away for free). If each plant cost the store $2.90, how much money did the store lose
by giving away the free plants?
Answer:
the shop lost $922.20 by giving away free vegetable plants.
Step-by-step explanation:
you would start by dividing 636 by two to see how many free vegetable plants were given away.
636 / 2 = 318
this shows us how many free vegetable plants were given for free, so then to find how much money the store lost giving them away for free, you would multiply 318 by 2.9
318 x 2.9 = 922.2
Therefore the shop lost $922.20 by giving away free vegetable plants.

Yvette uses 6grams of tea leaves to make 24 fluid ounces of tea last week she made 288. Fluid ounces of tea how many grams of tea leaves did Yvette use to make tea last week
Answer: 72 grams of tea
Step-by-step explanation:
From the question, we are informed that Yvette uses 6grams of tea leaves to make 24 fluid ounces of tea. This means that for 1 gram of tea leaves, she'll use:
= 24/6
= 4 fluid ounces of tea
Since, 1 gram of tea leaves will be used to make 4 fluid ounces of tea, therefore, the number of grams of tea leaves that will be used to make 288 fluid ounces of tea will be:
= 288/4
= 72 grams of tea

1) a verify : x² + 4x+3 = (x+2) ²)
Answer:
NO
Step-by-step explanation:
X^2+4X+3=(X+2)(X+2)
X^2+4X+3=X^2+2X+2X+4
X^2+4X+3=X^2+4X+4
Answer:
undefined
Step-by-step explanation:
x²+4x+3 = (x+2)²
first of all you open the bracket on the Right hand side..
(x+2)² = (x+2)(x+2)
= x(x+2)+ 2(x+2)
=x²+2x+ 2x+4
= x²+4x+4
therefore,
x²+4x+3 = x²+4x+4
next, we collect all like terms together,
x²-x²+4x-4x = 4-3
0+0 = 1
the answer is undefined
because 0 cannot be equal to 1

Answer:
1.2 × [tex]10^{-1}[/tex] of a second
Step-by-step explanation:
d = vt , t = d / v
t = ( 3.6 × [tex]10^{7}[/tex] )( 3 × [tex]10^{8}[/tex] ) = (3.6 ÷ 3) × ( [tex]10^{7}[/tex] ÷ [tex]10^{8}[/tex] ) = 1.2 × [tex]10^{7 - 8}[/tex] = 0.12 of second
t = 1.2 × [tex]10^{-1}[/tex] of a second
the diagram shows a right-angle triangle.
Answer:
Step-by-step explanation
The shortest length of the right-angled triangle is 4 cm.
What is a right-angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or anyone angles is a right angle.
Given is, the diagram shows a right-angle triangle.
We have area of the right-angle triangle = 18 cm²
We know that area of a right-angle triangle = 1/2(base)(height)
18 = 1/2(x - 1)(x + 4)
36 = (x - 1)(x + 4)
x² + 4x - x - 4 = 36
x² + 3x - 4 = 36
x² + 3x - 4 - 36 = 0
x² + 3x - 40 = 0
x² - 5x + 8x - 40 = 0
x(x - 5) + 8(x - 5) = 0
x + 8)(x - 5) = 0
x = -8 or 5
we can only use positive numbers because length can't be negative,
Thus, x = 5
The shortest side is definitely one of the 2 legs. The hypotenuse of a triangle is the longest side.
Therefore,
height = x - 1 = 5 - 1 = 4 cm
base = x + 4 = 5 + 4 = 9 cm
Hence, the shortest length of the right-angled triangle is 4 cm.

What is the volume of a cylinder with a diameter of 30 cm and a height of 40 cm? Use 3.14 for pie. Round to the nearest 10th.
Answer:
28,260.0 cm^3
Step-by-step explanation:
The volume of a cylinder uses the equation π[tex]r^{2}[/tex]h.To find the radius, divide the diameter by two, getting r=1/2(30)=15. Plug in all numbers getting:
3.14(15^2)(40)
=3.14(225)(40)
=28260
Answer:
V ≈ 28,260 cm³
Step-by-step explanation:
V = πr²h where,
V = volume
r = radius
h = height
π = 3.14
To find the value of the radius, we take half of the diameter.
1/2(30) = 15
Now that we have all the values, we plug them into the equation and round.
V = (3.14)(15)²(40) = 28,260
V = 28,260
Lara measured a swimming pool MAD scale drawing scale used what is 9 mm: 4 m in the drawing the pools 99 mm long what is the length of the actual pool
Answer: The actual pool is 44 m long.
Step-by-step explanation:
Given : The scale used for drawing :
9 mm: 4 m
i.e. for each 1 mm of drawing we have [tex]\dfrac{4}{9}\ \text{m}[/tex] of actual pool.
If the pool is 909 m long , then the actual pool will be [tex]\dfrac49\times99= 4\times11=44\text{ m long.}[/tex]
hence, the actual pool is 44 m long.

The league raised $1,560 through fundraisers. Trenton estimates the cost of buying jackets for each player in the league. He concludes that the league has raised enough money. Do you agree with Trenton? Explain.
Answer:
Step-by-step explanation:
Estimates are rough guesses based on current or previous prices. Therefore, it is impossible to conclude whether or not Trenton has actually raised enough money, especially if no actual price for the jackets has been provided. That being said an estimation is usually a close enough representation of the actual value, which would mean that the chances of having raised enough money (if that is what the estimates say) are pretty high.

the amount of sleep that elementary school children get per night follows a normal distribution with a mean of 9.5 hours and a standard deviation of 0.55 hours. is it unusual for an elementary student to get at least 12 hours of sleep?
Answer:
Yes, that is unusual as the problem is given.
Step-by-step explanation:
If the mean is 9.5 and the standard deviation is 0.55, then anything within the normal curve of 10.05 on the high end and 8.45 on the low end is normal. 12 is more than several standard deviations or an outlier if this makes sense.
So, it is unusual as the problem is stated, but if it's a weekend, 12 hours is normal. LOL
Good luck!
Based on the normal distribution parameters given, the probability of a student getting atleast 12 hours of sleep ls 0. Hence, it is abnormal.
Given the Parameters :
Mean = 9.5 Standard deviation = 0.55Using the Zscore formula, the probability of getting a atleast 12 hours of sleep can be expressed thus :
Zscore = (Score - Mean) / standard deviation
For X ≥ 12 :
Z = (12 - 9.5) / 0.55 = 4.545The probability using a normal distribution table :
P(Z ≥ 4.54) = 1 - P(Z ≤ 4.54)
P(Z ≤ 4.54) = 1 ( normal distribution table)
P(Z ≥ 4.54) = 1 - 1 = 0
Since, the probability is 0 ; hence, it is unlikely and therefore, abnormal.
