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

If sin y° = 9/c and tan y° = 9/d, what is the value of cos y°?
Answers
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

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.
Answers
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

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
Please triple check

the key to solving these is cross-multiplying and finding a common denominator, you can use photomath if you want to see the solving steps, hope this helps!
Which statement describes the relationship between x and y in these two equations? y = 2x and y = x + 2
A. In y = 2x he value of y is 2 more than the value of x, and in y = x + 2 the value of y is twice the value of x.
B. In y = 2x and in y = x + 2, the value of y is 2 more than the value of x.
C. In y = 2x and in y = x + 2, the value of y is twice the value of x.
D. In y = 2x the value of y is twice the value of x, and in y = x + 2 the value of y is 2 more than the value of x.

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?
Answers
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
What is the area of the figure? O 1240 units? 0 1250 units? o 2490 units? 0 3730 units
Answers
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

can someone help me ? Finding angle measures using triangles (veiw image)
Answers
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
King, a golden retriever, can find a tennis ball hidden in his yard 89% of the time, while Tessa, a Labrador mix, can find a tennis ball hidden in her yard 94% of the time. Suppose King’s owner hides a tennis ball in his yard 100 times and Tessa’s owner hides a tennis ball in her yard 150 times. Let K = the proportion of times King finds the tennis ball and T = the proportion of times Tessa finds the tennis ball. What is the probability that the proportion of tennis balls King finds is greater than the proportion Tessa finds?
