j’ai besoin d’aide pour cet exercice
Answer:
Step-by-step explanation:
A(x) = 4x³ - 4x²- 23x + 20
B(x) = 2x² + 3x - 4
C(x) = 2x - 5
a). A(x) + B(x) + C(x) = (4x³ - 4x²- 23x + 20) + (2x² + 3x - 4) + (2x - 5)
= 4x³ + (-4x² + 2x²) + (-23x + 3x + 2x) + (20 - 4 - 5)
= 4x³- 2x²- 18x + 11
b). A(x) - 2B(x) + 2C(x) = (4x³ - 4x²- 23x + 20) - 3(2x² + 3x - 4) + 2(2x - 5)
= 4x³ - 4x² - 23x + 20 - 6x² - 9x + 12 + 4x - 10
= 4x³ - 10x²- 28x + 22
c). A(x) . B(x) = (4x³ - 4x² - 23x + 20)(2x² + 3x - 4)
= 2x²(4x³ - 4x² - 23x + 20) + 3x(4x³ - 4x² - 23x + 20) - 4(4x³ - 4x² - 23x + 20)
= 8x⁵ - 8x⁴- 46x³ + 40x² + 12x⁴- 12x³ - 69x² + 60x - 16x³+ 16x²+ 92x - 80
= 8x⁵+ 4x⁴- 74x³- 13x²+ 152x - 80
d). [B(x)]² = (2x² + 3x - 4)²
= 2x²(2x² + 3x - 4) + 3x(2x² + 3x - 4) - 4(2x² + 3x - 4)
= 4x⁴ + 6x³ - 8x² + 6x³ + 9x² - 12x - 8x² - 12x + 16
= 4x⁴ + 12x³- 7x²- 24x + 16

1. Honda cars make up 18% of registered vehicles in Florida. You take a SRS of 500 car owners in Florida. What is the chance
your sample contains 20% or more of Honda owners? Use the 4-step plan.
Answer:
0.1349
Step-by-step explanation:
Given that:
Sample size, n = 500
20% of 500 ; 0.2 * 500 = 100
p = 0.18 ; n = 500 ; 1 - p = 0.82
P(x ≥ 100) ;
Using the binomial probability relation :
P(x =x) = nCx * p(x)^x * (1 - p)^(n - x
P(x ≥ 100) = 500C100 * 0.18^100 * 0.82^400
P(x ≥ 100) = 0.1349

What is the area of the figure? O 1240 units? 0 1250 units? o 2490 units? 0 3730 units
Answer:
2490
Step-by-step explanation:
The 2 shapes are triangle and trapezoid
Area of a triangle formula: A= h×b/2
A=40×62/2
A=1240
Area of a trapezoid formula: base¹+base²/2×height
A= 38+62/2×25
A=1250
Add both areas together
1250+1240=2490

On a coordinate grid, the coordinates of vertices P and Q for polygon RQRS are P(1, 2) and Q(-1, 2)
Park Jimin paid $125 to have his hair colored and cut. If he tips his hairdresser 15% of his bill, how much was the tip?
Money paid by Park Jimin = $125
We need to find the tip , so,
→ 15% of the amount paid
→ $ 125 (15/100)
→ $ 18.75
Hence, the tip is of $ 18.75

P(3,-5) T(x, y) = (x +4, y-3)
P' = ([?], []).
Enter the number that belongs in
the green box.
Enter
Answer:
The number that belongs in the green P' = ([?], [ ]) with P' = (7, -8) box is;
7
Step-by-step explanation:
The coordinate of the given point 'P' is P = (3, -5)
The preimage of (x, y) after the translation, [tex]T_{(x, \ y)}[/tex] = (x-coordinate + 4, y-coordinate - 3)
Therefore, the translation, [tex]T_{(x, \ y)}[/tex] = T₍₄, ₋₃₎
Therefore, we have;
Preimage P(3, -5) under the translation T₍₄, ₋₃₎ gives the image P' as follows
P(3, -5) [tex]\overset{T_{\left ( 4, \, -3 \right )}}{\rightarrow}[/tex]P'(3 + 4, -5 - 3) = P'(7, -8)
Therefore, the number that belongs in the green box is the x-coordinate value of the point P'(7, -8) which is seven.

Answer:
MP = 11
Step-by-step explanation:
By the Secants and Segments Theorem:
QR x QS = QM x QP
then:
(x + 4) x 4 = (x -5 + 5) x 5
4x + 16 = 5x
x = 16
MP = (x-5) = 16-5 = 11

Which problem can be solved using the equation 9x + 14 = 100
Answer:
rounded form: x = 9.56
Step-by-step explanation:
9x + 14 =100
you would 1st subtract 14 from 100 so you're left with
9x = 86
now to get x alone, you divide both sides by 9 so now you have
x = 9.56
can someone help me ? Finding angle measures using triangles (veiw image)
Answer:
x=52°
Step-by-step explanation:
Corresponding angles, 62° is parallel to I
so the letter I would be 62°.
In a triangle there's 180 degrees
so 180-62=118°-66=52°
that way all the angles in the triangle will add up to 180

Look at the figure below:
If sin y° = 9/c and tan y° = 9/d, what is the value of cos y°?
Answer:
d/cStep-by-step explanation:
Given:
sin y° = 9/c and tan y° = 9/dWe know that
tan α = sin α /cos α ⇒ cos α = sin α / tan αSolving for cos y°, by substituting values:
cos y° = sin y° / tan y° cos y° = 9/c ÷ 9/d = 9/c × d/9 = d/cAnswer:
the answer to your question is d/c

Amaia walks from her home to the bank, then to the park, and then to get groceries before heading home. The path she travels is in the shape of a parallelogram and is shown in the diagram below. How many total meters did Amaia walk?
Answer:
Amaia walked 28 meters
Step-by-step explanation:
So first we know that the side x+3 is equal to the side 3x+1
subtract 1 and x from both sides to get x=1
then we plug in the 1 to the equation x+9 and we know that side equals 10, meaning the parallel side is also 10.
plug in 1 to one of the original equations to get 4
4+4+10+10=28
