Functions:
f(x) = x2 – 5x – 6
f(x) = 23 – 22 – 12
f(x) = 5.24
Points:
f(0)
f(2)
f(-1)
f(6)
1) f(0)= -6 , f(2)= -12, f(-1)= 0, f(6)= 0
2) f(0)= -12 , f(2)= -8 , f(-1)= -14 , f(6)= 168
3) f(0)= 5 , f(2)= 20, f(-1)= 2.5 , f(6)= 320
Step-by-step explanation:
1) The given function is f(x) = x² – 5x – 6.
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = x² – 5x – 6
f(0) = -6
Therefore, f(0) = -6
Substitute x=2 in f(x) = x² – 5x – 6
f(2) = (2)² -5(2)-6
⇒ 4-10-6
⇒ 4-16
⇒ -12
Therefore, f(2) = -12
Substitute x= -1 in f(x) = x² – 5x – 6
f(-1) = (-1)² - 5(-1) -6
⇒ 1+5-6
⇒ 6-6
⇒ 0
Therefore, f(-1) = 0
Substitute x= 6 in f(x) = x² – 5x – 6
f(6) = (6)² - 5(6) -6
⇒ 36 -30 -6
⇒ 36-36
⇒ 0
Therefore, f(6) = 0
2) The given function is f(x) = x³– x²–12.
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = x³– x²–12
f(0) = -`12
Therefore, f(0) = -12
Substitute x= 2 in f(x) = x³– x²–12
f(2) = (2)³ - (2)² -12
⇒ 8-4-12
⇒ 8-16
⇒ -8
Therefore, f(2) = -8
Substitute x= -1 in f(x) = x³– x²–12
f(-1) = (-1)³ - (-1)² -12
⇒ -1-1-12
⇒ -14
Therefore, f(-1) = -14
Substitute x= 6 in f(x) = x³– x²–12
f(6) = (6)³ - (6)² -12
⇒ 216 -36 -12
⇒ 216-48
⇒ 168
Therefore, f(6) = 168
3) The given function is f(x) = [tex]5.24^{x}[/tex]
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = [tex]5.2^{x}[/tex]
f(0) = 5 × [tex]2^{0}[/tex]
Any number with power zero is 1.
f(0) = 5
Therefore, f(0) = 5
Substitute x=2 in f(x) = [tex]5.2^{x}[/tex]
f(2) = 5 × 2²
⇒ 5×4
⇒ 20
Therefore, f(2) = 20
Substitute x= -1 in f(x) = [tex]5.2{x}[/tex]
f(-1) = [tex]5\times2^{-1}[/tex]
⇒ 5 × 1/2
⇒ 5 × 0.5
⇒ 2.5
Therefore, f(-1) = 2.5
Substitute x= 6 in f(x) = [tex]5.2^{x}[/tex]
f(6) = [tex]5\times 2^{6}[/tex]
⇒ 5 × 64
⇒ 320
Therefore, f(6) = 320

Two linear functions are combined with addition, and then the same two linear functions are combined by multiplication.
Which functions could be the result of the combinations? Select two options.
16x - 12
17x - 12
72x? - 96x
72x2 - 108
72x2 - 204x + 144
Adding two linear functions results in a linear function, which could be represented as '16 x - 12' or '17 x - 12'. Multiplying two linear functions results in a quadratic function, which could be represented as '72 x² - 204 x + 144'.
Explanation:In this scenario, when the two linear functions are being combined by addition and multiplication, it results in an expression that could be either linear or quadratic. When you add two linear functions together: f(x) = ax + b and g(x) = cx + d, the result is also a linear function: h(x) = (a+c)x + (b+d). Therefore, both 16 x - 12 and 17 x - 12 could be the result of an addition of two linear functions.
However, when you multiply two linear functions, you get a quadratic function: i(x) = (ax + b)(cx + d) = acx^2 + (ad+bc)x + bd. So 72 x² - 204 x + 144 could be the result of a multiplication of two linear functions.

What is the sale price of 3 pepper plants after a 20% discount?
Answer: 12
Step-by-step explanation: cuz i said so
The sale price of 3 pepper plants after a 20% discount is $12.
Explanation:To figure out the sale price of 3 pepper plants after a 20% discount, we first calculate 20% of the regular price. The regular price of one pepper plant is $5, so 20% of $5 is $1. Therefore, the sale price of one pepper plant is $5 - $1 = $4. As Wes wants to buy 3 plants, we multiply this sale price by 3, so the total price after discount for 3 plants is $4 * 3 = $12.
So, the sale price of 3 pepper plants after a 20% discount is $12.

A circle has a circumference of 6. It has an arc of length 17/3. What is the central angle of the arc, in degrees?
Answer:
340 degrees
Step-by-step explanation:
So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).
So the circumference of a circle = 2pi(r)
This means:
6 = 2pi(r)
Which means that
r = 6/2pi or r = 3/pi
Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:
Arc length is defined by: length = θr
Where θ is our angle value.
So lets plug in:
[tex]\frac{17}{3} = (angle)\frac{3}{\pi }[/tex]
Multiply by pi to get:
[tex]\frac{17\pi }{3} = 3(angle)[/tex]
Divide by 3 to get that:
θ = 17pi/9
So if we convert that from radians to degrees we get 340 degrees.
2/sqrt(10) simplified
Answer:
20qrt/s / as in over
Step-by-step explanation:
To simplify 2/√(10), multiply the numerator and denominator by √(10) to get √(10)/5. This process removes the square root from the denominator.
To simplify the expression 2/√(10), we rationalize the denominator. This involves removing the square root from the denominator by multiplying the numerator and the denominator by the square root of 10.
Multiply the numerator and denominator by √(10):So, the simplified form of 2/√(10) is √(10)/5.

brainliest please ;)
Answer:
Only Hiroki
Step-by-step explanation:
His formula makes the most sense to the sequence.
The recursive formula to describe a sequence is shown below
a1=4
an=an-1+2n
State the first four terms of this sequence.
Given that the recursive formula for a sequence is [tex]a_n=a_{n-1}+2n[/tex]
The first term of the sequence is [tex]a_1=4[/tex]
We need to determine the first four terms of the sequence.
Second term:
The second term of the sequence can be determined by substituting n = 2 in the recursive formula.
Thus, we have;
[tex]a_2=a_{2-1}+2(2)[/tex]
[tex]a_2=a_{1}+2(2)[/tex]
[tex]a_2=4+4[/tex]
[tex]a_2=8[/tex]
Thus, the second term of the sequence is 8.
Third term:
The third term of the sequence can be determined by substituting n = 3 in the recursive formula.
Thus, we have;
[tex]a_3=a_{3-1}+2(3)[/tex]
[tex]a_3=a_{2}+2(3)[/tex]
[tex]a_3=8+6[/tex]
[tex]a_3=14[/tex]
Thus, the third term of the sequence is 14.
Fourth term:
The fourth term of the sequence can be determined by substituting n = 4 in the recursive formula.
Thus, we have;
[tex]a_4=a_{4-1}+2(4)[/tex]
[tex]a_4=a_{3}+2(4)[/tex]
[tex]a_4=14+8[/tex]
[tex]a_4=22[/tex]
Thus, the fourth term of the sequence is 22.
Hence, the first four terms of the sequence is 4, 8, 14, 22.

A painter estimates she can paint a house in 40 hours. She knows her assistant can do the same job is 60 hours. How long would it take them to paint the house working together?
24 hours
Step-by-step explanation:
1 hour
Painter1 1/40
Painter2 1/60
together 1/40+1/60=5/120=1/24
The time it would take them to paint a house working together is 24 hours.
How are number of people to time needed to complete a task related?(WORK DONE)More people to do a task means less time it will take.
Less people to do a task means more time it will take.
Thus, they are inversely related.
If x men take y time for a work,
We can define a constant as "Manpower" needed for doing that specific work.
Let we define:
Manpower needed for a work = y + y + y + .. + y = Time per man × count of men
Manpower needed for a work = xy
We are given that;
Time = 40hours
Time for her assistant= 60hours
Now,
First, let’s find their individual rates. The painter can paint 1/40 of a house per hour and the assistant can paint 1/60 of a house per hour. To find their combined rate, we add these fractions:
1/40 + 1/60 = 3/120 + 2/120 = 5/120
This means that together they can paint 5/120 of a house per hour. To find how long it would take them to paint one whole house (or 1/1), we use the formula:
Work done = Rate × Time 1/1 = (5/120) × Time Time
= (120/5) × (1/1) Time
= 24 hours
Therefore, by work and time the answer will be 24 hours.

will Taylor earn?
Answer: $661.50
Step-by-step explanation:
Taylor makes $771.25 per week and makes twice that much in two weeks.
2×771.25=2(700+70+1+0.25)=1400+140+2+0.50
So Taylor makes $1542.50 in two weeks.
Miley makes $440.50 per week and so will make $881 in two weeks. Since
1542.50−881=742.50−81=741.50−80=701.50−40=661.50
