What are the domain and range of the relation given in the table? Will Mark Brainliest. Need Help ASAP.
Answer:
we conclude that the domain of the table will be:
domain: {0, 5, 9, 32} range: {2, 3, 4, 7}
Therefore, option (C) is correct.
Step-by-step explanation:
Given the table
x y
0 3
5 4
9 2
32 7
We know that a relation consists of a set of ordered pairs.
The set of x-values of the ordered pairs is called the domain of a function.The set of y-values of the ordered pairs is called the range of a function.
Thus, we conclude that the domain of the table will be:
domain: {0, 5, 9, 32} range: {2, 3, 4, 7}
Therefore, option (C) is correct.

Answer:
Correct choice is 4, f(6) = 15
Step-by-step explanation:
f(6) means x = 6. If you look at the piecewise function, x = 6 meets the criteria for the second equation which is just 15. You need the first equation ONLY if x is less than 4.

Rose bought 5 large box lunches for $50. Which equation can be used to find the total cost, L, of a large box lunch?
Answer:
L= 50 divided by 5
Answer:
L=10*x
X being the total number of box lunches
In this case L=10*5 = 50
Step-by-step explanation:
Total cost =L
1 large box lunch = 50/5=10
Therefore the total cost would be
L=10*X
x being the total number of box lunches
You've been saving $8.50 each week to buy a bicycle from your local bike store. The bike originally cost $210, but is on sale for 25% off. So far, you have saved $120 for your purchase. How many more weeks must you save up to have enough money to buy the bike?
Answer:
5 weeks
Step-by-step explanation:
First, you must calculate what 25% off from $210 is. Since 100 - 25% = 75%, the price of the bike is 75% of $210.
[tex]\frac{x}{210}=\frac{75}{100}[/tex]
[tex]100 * x = 75 * 210[/tex]
[tex]100x = 15750[/tex]
x = $157.50
Then, make an equation that represents the money needed to save up for the bike.
y = mx + b
bike's price = (money earned each week)(number of weeks) + money saved
157.5 = 8.50x + 120
157.5 - 120 = 8.50x + 120 - 120
37.5/8.5 = 8.5x/8.5
x = 4.4117
You need to round 4.4 to 5 because number of weeks must be whole numbers

Step-by-step explanation:
Solve for z. Assume the equation has a solution for 2. -p: (8 + x) = -22 +59 Anybody?
Answer:
z= pd + 59 / (2-p)
Step-by-step explanation:
-p (d+z) = -2z +59
-pd - pz = -2z +59
-pz +2z = pd +59
z ( 2-p) = pd + 59
z= pd +59 / (2-p)

Keyless door entries require you to input your 6 digit passcode in the correct order. How many different 6 digit passcodes can be created from 10 digits, if all of the digits must be distinct?
Give your answer in simplest form.
Provide your answer below:
Answer:
151200
Step-by-step explanation:
We want to know how many permutations of 6 digits can be chosen from 10 different digits, so we use the formula:
nPr=n!(n−r)!
Here, r=6 and n=10, so we have:
10P6=10!(10−6)!=10!4!=10⋅9⋅8⋅7⋅6⋅5⋅4!4!=151,200

Answer:
The minimum value of f(x) is 2
Step-by-step explanation:
To find the minimum value of the function f(x), you should find the value of x which has the minimum value of y, so we will use the differentiation to find itDifferentiate f(x) with respect to x and equate it by 0 to find x, then substitute the value of x in f(x) to find the minimum value of f(x)∵ f(x) = 2x² - 4x + 4
→ Find f'(x)
∵ f'(x) = 2(2)[tex]x^{2-1}[/tex] - 4(1)[tex]x^{1-1}[/tex] + 0
∴ f'(x) = 4x - 4
→ Equate f'(x) by 0
∵ f'(x) = 0
∴ 4x - 4 = 0
→ Add 4 to both sides
∵ 4x - 4 + 4 = 0 + 4
∴ 4x = 4
→ Divide both sides by 4
∴ x = 1
→ The minimum value is f(1)
∵ f(1) = 2(1)² - 4(1) + 4
∴ f(1) = 2 - 4 + 4
∴ f(1) = 2
∴ The minimum value of f(x) is 2

(1 point) 1. The height (in feet) and volume of usable lumber (in cubic feet) of 32 cherry trees are measured by a researcher. The goal is to determine if volume of usable lumber can be estimated from the height of a tree. The results are plotted below.(a) In this study, the response variable isA. neither height nor volume. The measuring instrument used to measure height is the response variable.B. height or volume. It doesn't matter which is considered the response.C. volume.D. height.
Answer:
C. volume
Step-by-step explanation:
The response variable in this scenario would be the volume of the usable lumber. That is because this variable depends completely on the height of the cherry trees that are being measured. The higher that the cherry trees are the more volume can be expected to get from cutting these trees down. The opposite goes for trees that are smaller, they would decrease the total expected volume that will be received from the usable lumber since there would be less amount of tree to cut down.

Andres playsa soccer video game. He earns 3 stars for every goal hs scores and loses 3/4 stars every time he misses the goal. He scores 5 goals and misses the goal 4 times. How many stares does he have
Answer:
Andres has 12 stars.
Step-by-step explanation:
3 stars - 1 goal-3/4 stars - Missed goalScored 5 Missed 43 * 5 = 15
He has 15 stars but then misses 4 goals.
3/4 * 4 = 3
He loses 3 stars becuase he missed 4 goals.
15 - 3 = 12
He ends with 12 stars.
Find the mean, median, and mode for 0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7.
Round to the nearest tenth if needed.
answer
for the median its 7
for the mean its 6.
the mode is 9
Step-by-step explanation:
The mode is the value that appears most frequently in a data set.
Median:The number in the MIDDLE when they are IN ORDER!
Mean- The AVERAGE OF ALL NUMBERS: You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!
A road rises vertically 6 feet for every 100 feet traveled horizontally. What is the rate of change in vertical feet compared to horizontal feet as a car travels this road? ...... !Please answer quickly!
The basis of this problem is that slope = (vertical distance)/(horizontal distance), also called rise/run
We can set this up as a proportion. I'll use V and H for the distances in the formula
V/H = 8/100 I'm ignoring the negative sign, because it is just telling us that the road is descending.
We know that V = 1000, so we have 1000/H = 8/100
Now we cross multiply, to get 1000x100 = 8H
100,000 = 8H Divide both sides by 8 to get H = 100,000/8 = 25,000 ft.
We aren't finished, though, because we were asked to give the distance in miles.
1 ft = 5,280 mi, so each foot is 1/5280 miles, and 25,000 ft = 25,000x1/5280 = 4.73 miles

Step-by-step explanation:
distance (meters)
time (seconds)
A
114
Answer:
Time = 91.2 seconds
Step-by-step explanation:
Since, Tyler swims at a constant speed 5 meters every 4 seconds.
Relation between distance and time is always proportional.
Therefore, d ∝ t
d = kt
Here, k = proportionality constant
For d = 5 m and t = 4 seconds
5 = 4k
k = [tex]\frac{5}{4}[/tex] = 1.25
So the relation is, d = 1.25t
Now we have to find the time taken to cover 114 m.
From the given relation,
114 = 1.25t
t = [tex]\frac{114}{1.25}[/tex]
t = 91.2 seconds
Find all zeros of the function
Answer:
x=-1,-3,2i and -2i
Step-by-step explanation:
By plugging in x=-1, f(x)=0 and x=-3,f(x)=0
That means x+1 and x+3 are roots of the fourth degree polynomial.
(x+1)(x+3)=x²+4x+3
Divide the polynomial by x²+4x+3 and that gives x²+4.
We now find the zeros of the factors
(x²+4x+3)(x²+4)=0
x=-1,-3,2i and -2i

How many can 1/4 fit into 3/8
Answer: 1
Step-by-step explanation:
1/4 is equivalent to 2/8
3/8 - 2/8 = 1/8
Since you can only subtract 2/8 (or 1/4) from 3/8 once, one 1/4 can fit into 3/8.

Answer:
4. -35. -1/26. 1/27. 48. 09. undefinedStep-by-step explanation:
Use of slope formula:
m = (y2 - y1)/(x2 - x1)4.
m = (7 - 4)/(1 - 2) = 3/-1 = -35.
m = (-2 - 0)/(3 - (-1)) = -2/4 = -1/26.
m = (5 - 3)/(5 - 1) = 2/4 = 1/27.
m = (3 - 0)/(3.5 - 4.25) = 3/0.75 = 48.
m = (3/4 - 3/4)/(5 - 2) = 09.
m = (2 - 3)/(7.5 - 7.5) = -1/0 = undefined
