Step-by-step explanation:
[tex]\begin{cases} -3x -3\:\: for\:\: x<-2\\\\6x -28\: \: for\:\: x\geq 5 \end{cases}[/tex]
f(5) will fall in the interval x≥5 and its corresponding function is:
f(x) = 6x - 28
∴ f(5)= 6*5 - 28 = 30 - 28 = 2

Which equation below will give a graph of a line parallel to the graph of -2x - 4y = 3?
Answer:
Any choice that has a slope of -1/2
Step-by-step explanation:
-2x - 4y = 3
-4y = 2x + 3
4y = -2x - 3
y = -1/2x -3/4
y = mx + b
m = slope
Solve (x + 3 < 5) U (x - 7 > 1).
{ x | 2 < x < 8}
O/
{ x | x < 2 or x > 8}
Answer:
{ x | x < 2 or x > 8}
Step-by-step explanation:
Given the expression
(x + 3 < 5) U (x - 7 > 1).
Solve x+3 < 5
Subtract 3 from both sides
x+3 - 3 < 5-3
x < 2
For x - 7 > 1
Add 7 to both sides
x-7+7 > 1 + 7
x > 8
Hence the union of both is { x | x < 2 or x > 8}

Erica can thoroughly analyze the company’s monthly credit card statements
in 80 minutes. It takes Alexa 2 hours to do the same job. One afternoon, Erica and Alexa start analyzing the company’s credit card statements together. Half an hour later, Mack, the new employee, joins them. If the three of them finish 15 minutes later, how long would it have taken
Mack to analyze the company’s monthly credit card statements on his own?
Answer:
240 minutes or 4 hours
Step-by-step explanation:
So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.
If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.
Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.
So you have 45/80 and 45/120.
Now add both fractions by finding the lowest common denominator which is 240.
135/240 + 90/240 = 225/240
So Mack did the remaining 15/240.
Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.
Then multiply
15 x 16 = 240
so it would take him 240 minutes or 2 hours.
A coin is tossed 7 times. What is the probability of getting all tails? Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Answer:
0.0078125
Step-by-step explanation:
Probability of tail, p = 0. 5
Probability of getting all tails from 7 tosses :
P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail)
0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.0078125
We could also use the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - r)
n = 7 ; x = 7, p = 0.5,
P(x = 7) = 7C7 * 0.5^7 * 0.5^0 = 0.0078125

Round your answer to the nearest hundredth
Answer:
∠ B ≈ 66.42°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosB = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{2}{5}[/tex] , then
∠ B = [tex]cos^{-1}[/tex] ( [tex]\frac{2}{5}[/tex] ) ≈ 66.42° ( to the nearest hundredth )

Triangle QRS is a right triangle.
What is the lenghts of RS.
0 10
0 7.1
05.3
0 14
Answer:
5.3
Step-by-step explanation:
a² + b² =² c² the Pythagorean theorem
RQ² + RS² = QS² Solve RS
6² + RS² = 8²
RS² = 64 -36
RS² = 28
RS = √28 28 is slightly > 25 and since √25 =5
RS = 5.3 actually 5.2915 to a few more significant digits
A 3 pound package of ground beef sells for $6. At this rate, if John buys 10 pounds of
ground beef, how much would he pay?
Answer:
$20
Step-by-step explanation:
3 pounds of beef is 6 dollars.
6 divided by 3 is 2. Therefore, each pound cost $2.
He wants to buy 10 pounds of beef.
9 pounds would be $18.
Add 1 pound, which is $2 and you will get $20.
Therefore, he would pay $20!~

Which weighs more: a puppy that weighs 8.5 kilograms or a baby that weighs 11 pounds? Explain your reasoning.
Answer:
a baby weight more because the baby will grow and will weight more then a puppy
Step-by-step explanation:
Answer:
A puppy that weights 8.5 kilograms weighs more.
Step-by-step explanation:
A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.
Puppy's Weight Kilograms: 8.5
Puppy's Weight Pounds 18.7
Baby's Weight Kilograms: 5
Baby's Weight Pounds: 11
Weight in Kilograms: Puppy: 8.5 > Baby: 5
Weight in Pounds: Puppy: 18.7 > Baby: 11
Therefore, the puppy is heavier.

PLEASE HELP ME ITS DUE In 10 mins please
Answer:
Step-by-step explanation:
Part A
Since, BDFHJ is a regular pentagon,
Measure of interior angles of this pentagon = [tex]\frac{(n-2)\times 180}{n}[/tex]
= [tex]\frac{(5-2)\times 180}{5}[/tex]
= 108°
Since, ∠ABC ≅ ∠JBD [Vertical angles]
Therefore, m∠ABC = m∠JBD = 108°
Part B
m∠JBD + mCBD = 180° [Linear pair of angles]
108° + m∠CBD = 180°
m∠CBD = 180 - 108
m∠CBD = 72°
Similarly, m∠BDF + m∠CDB = 180°
m∠CDB + 108° = 180°
m∠CDB = 180 - 108
= 72°
In ΔCBD,
m∠BCD + m∠CDB + m∠DBC = 180°
m∠BCD + 72° + 72° = 180°
m∠BCD = 180° - 144°
= 36°
An employee does not pay tax on the first $4000 of earnings and then 25% tax on the rest of earnings. If he wants to have $20000 net of tax earnings does he need
Answer:
$68000
Step-by-step explanation:
Tax free earning = first 4000
Tax on remaining amount = 25%
Total earning in other to have $20000 net of tax earning :
Net of tax = tax free earning + (25% * remaining amount)
Let remaining amount = x
20000 = 4000 + (0.25 * x)
20000 = 4000 + 0.25x
20000 - 4000 = 0.25x
16000 = 0.25x
x = 16000 / 0.25
x = 64000
Hence,
Total earning should be :
Tax free earning + roaming amount
4000 + 64000
= $68000

Answer:
the mean is 3.95
median is 2.75
Step-by-step explanation:
I'd say that the mean is the better center, because you need to even it all out. you have one big number compared the rest.
The median is a better center for this data since since that number is the common size of acres not the highest or lowest acre per 1000 residents
