Find all the zeroes of g(x)=4x^4+4x^3-11x^2-12x-3
Answer:
The zeroes of [tex]g(x)=4x^4+4x^3-11x^2-12x-3[/tex] are [tex]-\sqrt{3}, -\frac{1}{2}, \sqrt{3}[/tex], or approximately [tex]-1.732, -0.500, 1.732[/tex].
Step-by-step explanation:
Graphical calculator way (probably intended)By inputting the function in a graphical calculator we can see that the roots of the graph of [tex]g[/tex] are about [tex]x=-1.732, x = 0.500, x = 1.732[/tex] (make sure you click on the points of interests).
Algebraic way (probably not intended because of obscure factoring)Notice that [tex]g(x) = 4x^4+4x^3-11x^2-12x-3 = (2x-1)^2(x^2-3).[/tex] So the roots can be calculated with [tex](2x-1)^2 = 0 \vee x^2 - 3 = 0[/tex], yielding [tex]x = -\frac{1}{2} \vee x = \pm\sqrt{3}[/tex].

Step-by-step explanation:
When dealing with graphs, involving points in between numbers, we have to carefully look at the x and y axis.
On the graph, the y-axis is going by 2s: 0, 2, 4, 6, 8, 10
On the x-axis, it's going by 1s: 0, 1, 2, 3, 4, 5, 6
Between 2 and 4 is 3
Between 4 and 6 is 5
Between 6 and 8 is 7
Between 8 and 10 is 9
Between 2 and 3 is 2.5
Between 3 and 4 is 3.5
Between 4 and 5 is 4.5
Between 5 and 6 is 5.5
Between 6 and 7 is 6.5
Between 7 and 8 is 8.5
Between 8 and 9 is 8.5
Between 9 and 10 is 9.5
Between 10 and 11 is 10.5
You get to see the pattern going on here...
On point E, we can see that the x-axis is 2.
Now on the y-axis, it is between 6 and 7. But if you look closely, you'll see that it's not on the line, that indicates 6.5.
So we find the median...
6, 6.1, 6.2, 6.3, 6.4, 6.5 6.2 and 6.3 are on the medium
[tex]\frac{6.2 + 6.3}{2}[/tex] = 6.25 Answer on E: (2, 6.25)
On point F, we can see that the x-axis is 3.
On the y-axis, it is between 8 and 10, which would be 9, BUT, look closely that it's also between 9 and 9.5.
The answer would be 9.5, but it is SLIGHTLY below 9.5, so I think it's 9.4
Answer on F: (3, 9.4)
On point G, the x-axis is between 3 and 4, so it's 3.5.
On the y-axis, we know it's going by 2s. We can see that G is between 10 and 12, so it would be 11. Because it is on that thin line, as you can see.
Answer on G: (3.5, 11)

Given that ΔABC ∼ΔDEF, m∠A = 108 degrees and m∠E = 40 degrees. Find m∠F. Type ONLY the number of degrees.
Answer:
∠F = 32°
Step-by-step explanation:
ΔABC & ΔDEF are similar triangles. So, corresponding angles of both triangles are congruent
∠D = ∠A = 108
∠B = ∠E = 40
∠C = ∠F
In ΔDEF,
∠D +∠E + ∠F = 180 {Angle sum property of triangle}
108 + 40 + ∠F = 180
148 +∠F = 180
∠F = 180 - 148
∠F = 32°

Phyllis invested $13,000, a portion earning a simple interest rate of 5¼% per year and the rest earning a rate of 5% per year. After one year the total interest earned on these investments was $672.50. How much money did she invest at each rate?
Answer:
Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.
Step-by-step explanation:
Formula for the simple interest is,
Interest = [tex]\frac{P\times r\times t}{100}[/tex]
Here, P = Principal amount
r = rate of interest
t = Duration of investment
Let Phyllis invested amount (at 5.25% rate of interest) = $x
Therefore, Interest on this amount,
Interest = [tex]\frac{5.25\times x}{100}[/tex]
= $0.0525x
If he invested the rest amount $(13000 - x) at the rate of 5%,
Interest earned on this amount = [tex]\frac{(13000-x)\times 5\times 1}{100}[/tex]
= $(650 - 0.05x)
Interest earned on total amount = $672
Therefore, $0.0525x + $(650 - 0.05x) = $672.5
0.0025x + 650 = 672.5
0.0025x = 22.5
x = $9000
Rest amount = 13000 - 9000
= $4000
Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.
80% of all households have a rice cooker. 35% of all households have a rice cookers and an instant pot. What is the probability that a household has an instant pot given that it has a rice cooker?
Answer:
A rice cooker, also known as a rice steamer, is a popular small appliance that works like a slow cooker by using moist heat to cook food while trapping the flavors in the pot until it’s ready to enjoy. Modern rice pressure cookers significantly reduce rice-making time and often feature a warming setting so you can be flexible with meal times.

Which of the following represents the range of the function table?
A. {-3, 1, 7}
B. {-6, -3, -2, 1, 5, 7}
C. {0, 1, 2, 3, 4, 5, 6}
D. {-6, -2, 5}
The range of the given table would be set of all possible y-values as {-6, -2, 5} which is the correct answer would be an option (D).
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
We have been given that table as:
x y
-3 -6
1 -2
7 5
As per the given table, the required solution would be as:
The range of a function is the set of all possible output values of the function. In this case, the output values of the function are the y-values in the table. The range of the function table is the set of all possible y-values, which in this case is {-6, -2, 5}.
Therefore, the range of the function table is therefore -6 to 5.

Answer:
a.
Step-by-step explanation:
this is a y = mx + b equation
the “B” is the y-intercept. So look where the line crosses the 6 axis. The equation says -1. Right away, there are only two answers that could possibly be it. A and B. The Lines both cross at -1 on the y-axis.
the ”mx“ part of the equation is the slope. Slope is the change in y over the Change in x.
in other words:
y1-y2
———
x1-x2
another thing is that slope in this equation is negative. This means the line is decreasing or going/pointing down. The only possible answer is a.
9 sec x + 9 tan x = 9
Answer:
Lowest root is 0 degrees.
Step-by-step explanation:
divide through by 9:
sec x + tan x = 1
sec^2x = 1 + tan^2 x so
√(1 + tan^2x) + tanx = 1
√(1 + tan^2x) = 1 - tanx
Squaring both sides:
1 + tan^2 x = 1 - 2 tanx + tan^2 x
1 = 1 - 2 tan x
2tanx = 0
x = 0 degree.

Step-by-step explanation:
In the figure below, m_1=(x-9° and m2 =6xº.
Find the angle measures.
Help!!!!
Answer:
(x-9)°+6x=180°[by linear pair]
7x-9=180°
7x=180°+9
7x=189°
x=189/7
x=27
(x-9)°=27-9=18°
(6x)°=6×27=162°
The angle measures are 18 degrees and 162 degrees.
What is Angle?An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
In the given figure ∠1=x-9 and ∠2=6x
The sum of ∠1 and ∠2 is 180 degrees by linear pair.
∠1 +∠2 =180
x-9+6x=180
Add the x variable terms
5x-9=180
Add 9 on both sides
5x=189
Divide both sides by 5
x=27
Now substitute value of x in angle 1 and angle 2.
∠1=x-9=27-9=18 degrees
∠2=6x=6(27)=162 degrees.
Hence, the angle measures are 18 degrees and 162 degrees.

What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given is that the red line cable car is 32 km long and advances at a speed of 6 m/s. You go up to the top and -
Advance for 50 seconds and the cable car stops.Begins to go backwards for 3 seconds.Then it advances again for 5 minutes.Then again it goes backwards for 2 minutes.Then it advance again to its final stop in the next 10 minutes.Time elapsed in first advancement = 50 seconds.
Total time after second backward motion = 50 + 3 = 53 seconds.
Total time after third forward motion = 53 + 300 = 353 seconds
Total time after fourth backward motion = 353 + 120 = 473 seconds
Total time after fifth forward motion = 473 seconds + 600 = 1073 seconds.
Therefore, the total time elapsed will be 1073 seconds.
