Which polynomial expression in factored form has2 as a leading coefficient with 0, -1, 6, and -4 as zeros?
Answer:
p(x) = 2*x^4 - 2*x^3 - 52*x^2 - 48*x
Step-by-step explanation:
For a polynomial p(x) with leading coefficient A, and zeros: {x₁, x₂, ...,xₙ}
The polynomial can be written in the factored form as:
P(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)
In this case, we know:
Leading coefficient equal to 2, and the zeros are: 0, -1, 6, and -4
Then the polynomial can be written as:
p(x) = 2*(x - 0)*(x - (-1))*(x - 6)*(x - (-4))
p(x) = 2*x*(x + 1)*(x - 6)*(x + 4)
The wanted polynomial is this one, and we can expand it to get:
p(x) = (2*x^2 + 2*x)*(x - 6)*(x + 4)
p(x) = (2*x^3 - 12*x^2 + 2*x^2 - 12*x)*(x + 4)
p(x) = (2*x^3 - 10*x^2 - 12*x)*(x + 4)
p(x) = 2*x^4 + 8*x^3 - 10*x^3 - 40*x^2 - 12*x^2 - 48*x
p(x) = 2*x^4 - 2*x^3 - 52*x^2 - 48*x
What's the area of the composite figure below ?
Answer:
31.13
Step-by-step explanation:
If you look carefully, you will find a semicircle and a triangle.
The total area is =
[tex]\frac{\pi r^{2}}{2} + \frac{1}{2} \times base \times height\\[/tex]
r = 4 - 0 = 4base = |-4-0 | = 4height = 14 - 9 = 5So if we put the values:
[tex]\frac{\pi \times 4^{2}}{2} + \frac{1}{2} \times 4 \times 3\\= 31.13[/tex]

Neil has 3 partially full cans of white paint. They contian 1/3 gallon, 1/5 gallon and 1/2 gallon of paint. About how much paint does neil have
Answer:
1 1/30 gallon
Step-by-step explanation:
Can A = 1/3 gallon
Can B = 1/5 gallon
Can C = 1/2 gallon
Total paint Neil has = Can A + Can B + Can C
= 1/3 + 1/5 + 1/2
The lowest common multiple of 3, 5 and 2 is 30
= (10+6+15) / 30
= 31/30
= 1 1/30 gallon of paint
Neil has a total of 1 1/30 gallon of paint
A straw has a diameter of 0.6cm and a length of 19.5 cm. What is the surface area of the straw round to the nearest tenth. Use 3.14 for pie
Answer:
37.3032cm^2
Step-by-step explanation:
Given data
Diameter= 0.6cm
Radius= 0.3cm
Lenght = 19.5cm
Surface area (A) =2πrh+2πr^2
Substitute
A=2*3.14*0.3*19.5+2*3.14*0.3^2
A=36.738+0.5652
A=37.3032
Hence the surface area is
37.3032cm^2

Answer:
x=33
Step-by-step explanation:
1) write the equation: 180=90+(x+15)+(x+9)
2) subtract 90 on both sides and add x+15 and x+9 together: 90=2x+24
3) subtract 24 from both sides: 66=2x
4) divide both sides by 2: x=33
88=(−x+3)8 , please? step by step? thanks <33
Answer:
-8
Step-by-step explanation:
88=(-x+3)8
88= -8x+24
88-24= -8x
64= - 8x
- x= 64/8
-x=8
x= -8
88 = ( -x + 3) x 8
88 = (3-x) x 8
8= 8 (3-x)
88/8 = 3 - x
11 - 3 = -x
8 = -x
-8 = x
x = -8

Answer:
a = 4, x = 1
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
WX = YZ , that is
a² + 5a = 5a + 16 ( subtract 5a from both sides )
a² = 16 ( take the square root of both sides )
a = ± [tex]\sqrt{16}[/tex] = ± 4
Since a > 0 , then a = 4
Also
XY = WZ , that is
x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Since x > 0 , then x = 1
A cone has radius 3.8 cm and height 7.6 cm. The radius and the height are doubled. Which of the following describes the effect on the volume?
Answer:
The volume is multiplied by 8.
Step-by-step explanation:
The volume of a cone with a radius of 3.8 and a height of 7.6 is 114.92. Now let’s double them, the results come out to be 919.39, we divide these by each other and we get roughly 8 when you round. Therefore, your answer is 8.
How much sand do you need to add to 3.2m^3 of soil with 40% sand in order to make a soil with 60% sand
Answer:
[tex]1.6m^3[/tex] sand is to be added to make sand percentage [tex]60\%[/tex]
Step-by-step explanation:
From the question we are told that:
Total soil [tex]N=3.2m^3[/tex]
Initial sand percentage [tex]S_1=40\%[/tex]
Final sand percentage[tex]s_2=60\%[/tex]
Generally the sand and other particles division is mathematically given by
[tex]40\% of 3,2=1.28[/tex]
and
[tex]60\% of 3.2=1.92[/tex]
Generally what will make 60\% of 3.2 40\% is mathematically given by
[tex]x=1.92*0.4\\x=4.8[/tex]
Generally the sand to be added is mathematically given by
[tex]4.8sand-3.2sand =1.6m^3[/tex]
Therefore
[tex]1.6m^3[/tex] sand is to be added to make sand percentage [tex]60\%[/tex]
Imagine that you need to create a scale drawing of this sign. The scale drawing will
be used to create a mold that will be used to manufacture the sign. Use the grid to
make a scale drawing of this sign. Include a key to show the relationship between
the dimensions in the scale drawing and the dimensions of the actual sign. Label all
sides in the scale drawing. Show your work. (3 points)
A scale drawing with a 1: 0,8 scale will have sides that measure 2.24, 1.6, and 3.2.
What is a scale drawing?A scale drawing refers to a drawing that has been made bigger or smaller but preserves the proportions of a drawing.
How to make the scale drawing of the sign?The first step is to decide the scale. In this case, the best scale is 1:0.8, which means the new drawing is 0.2 smaller. This scale is ideal because this sign is slightly bigger than regular signs.
Draw the sign by multiplying each side by the scale (0,8).

If you flip a coin 15 times and it lands on heads every time, what is the probability of the coin landing on heads on
the next flip?
Answer:
Its depends on theoretical and experimental
Step-by-step explanation:
The experimental you have flipped it 15 times and got heads every time, so you have an experimental of 15/15 of heads, but theoretical is a 1/2, or 50/50, a 50% chance of getting heads or tails.
How to solve X²-X-42uing
using Fertoning Polynomials
Answer:
x = - 6, x = 7
Step-by-step explanation:
Begin by equating to zero
x² - x - 42 = 0
Consider the factors of the constant term (- 42) which sum to give the coefficient of the x- term (- 1)
The factors are - 7 and + 6 , since
- 7 × + 6 = - 42 and - 7 + 6 = - 1 , then
(x - 7)(x + 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 7 = 0 ⇒ x = 7
