Answer:

  f(x) = x³ -4x² -5x +20

Step-by-step explanation:

If the function is to have rational coefficients, each complex or irrational square root must have a matching conjugate. That is, both -√5 and +√5 must be roots. If there is a root p, then there is a factor (x -p). The factored form of the minimal polynomial is ...

  f(x) = (x -4)(x +√5)(x -√5)

  = (x -4)(x² -5)

  f(x) = x³ -4x² -5x +20

If I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

The term PEMDAS describes the sequence in which arithmetic operations must be carried out in an equation.

It is given that the length of the toy model car is 15 inches and the actual car is 20 feet

As we know 1 foot consists of 12 inches as a result  20 feet has 240 inches.

The scale distance between the toy model and the actual car is the difference between the actual length and the model length.

Scale distance = 240 inches - 15 inches

Scale distance =225 inches

Thus, if I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.

Answer:

f =18

Step-by-step explanation:

The sum of the angles of a triangles is 180

3f+6f+f = 180

10f = 180

Divide by 10

10f/10=180/10

f = 18

Answer:

48 in²

Step-by-step explanation:

Hello!

Area of a Triangle: [tex]A = \frac12 b*h[/tex]

Given that the base and height are 8 and 12, we can plug it into the formula to solve for the area.

The area of the triangle is 48 in².

Answer:

is this even a real question?

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

6x - 7y = 4

We are given that y = 2

6x - 7(2) = 4

6x - 14 = 4

Add 14 on both sides to leave the 6x alone

6x = 18

Divide by 6 to isolate x and find the value of x

x = 3

We can further prove this by putting in the value of x

6(3) - 7(2) = 4

18 - 14 = 4

Which is correct

Answer:

50$$$

Step-by-step explanation:

(she has the same name as me lol)

Chloe has to pay 40$

5% of 40 is 2

20% of 40 is 8

Add the extra money together

2+8=10

Add original price

40+10=50

You get 50$ for the final price

Answer:

32 seconds

Step-by-step explanation:

The median is the exact middle of the data after putting the data in order. In this example, it would be 32 seconds.

23, 23, 28, 31, 32, 34, 47, 49, 56

Answer:

X=3

Step-by-step explanation:

2 times 7x = 14x

2 times -6 = -12

14x-12=30

(+12)

14x=42

(÷14)

X=3

Since 20% down payment, we will find the 20% of that $250,000.

10% is $25,000, now times by 2 would be 20% which is $50,000.

Now $250,000 - $50,000 = $200,000 which would be rest of the non-payed payment.

We will divide $200,000 with the 25 year loan. $200,000/25 = $8,000

There is also the 5% interest.

1% of $8,000 is $80 and times that by 5 would be 5% which is $400.

$8,000 + $400 = $8,400.

Since it is monthly, we will divide $8,400 by 12 months. $8,400/12 = $700.

The monthly payment would be $700.

(I hope this is correct.)

Step-by-step explanation:

To calculate each slope, just take any two points from each table, and plug them into this formula:⤵⤵⤵

(It'll be a bit small btw)

[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]

Table 1: I chose points (13,1) and (5,21)

21 - 1 = 20

5 - 13 = -8

Simplified = -5/2 ⬅ Slope

Table 2: I chose points (4,16) and (9,19)

19 - 16 = 3

9 - 4 = 5

3/5 ⬅ Slope

Table 3: I chose points (0,6) and (9,0)

0 - 6 = -6

9 - 0 = 9

Simplified = -2/3 ⬅ Slope

Table 4: I chose points (-8,1) and (-8,17)

17 - 1 = 16

-8 - (-8) = -8 + 8 = 0

Undefined slope (meaning the line will just be verticle)

Table 5: I chose points (2,3) and (3,5)

5 - 3 = 2

3 - 2 = 1

Simplified = 2 ⬅ Slope

Hope this helps :)

Answer:

D.

Step-by-step explanation:

Pretend the y-axis is a wall, on the left side it is decreasing and on the right it is increasing, so A. and B. aren't correct. C. and D. are left, x<0 means on the left side of the y-axis because x (any number) is less than 0 and on the left side it is decreasing so C. isn't correct so D. is your answer because x>0 means x is greater than 0 so it's on the left side of the y-axis.

I hope this helps!
