Answer:
-1, 3, -3
Step-by-step explanation:
I don't see the graph, but you can solve by factoring:
[tex]x^3+x^2-9x-9=0\\x^2(x+1)-9(x+1)=0\\(x+1)(x^2-9)=0\\(x+1)(x+3)(x-3)=0[/tex]
By the factor theorem, the solutions of f(x) are -1, 3, and -3.
The requried solutions of x³ + x² - 9x - 9 = 0 is x = -3, -1, 3. Option C is correct.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.
Here,
To find the solutions of equation x³ + x² - 9x - 9 = 0, we need to find the x-intercepts of the graph of the function f(x) = x³ + x² - 9x - 9.
From the graph, we can see that the function intersects the x-axis at three points, which are approximately -3, -1, and 3. Therefore, the solutions of the equation are x = -3, x = -1, and x = 3.
Thus, the correct answer is x = -3, -1, 3.
Options A, B, and D are incorrect because they either do not include all three solutions or include additional solutions that are not present in the graph of the function.

If x and y are two rational numbers such that x < y , then ______ is a rational number in between x and y.
Answer:
[tex]\dfrac{x+y}{2}[/tex]
Step-by-step explanation:
Let first number be x and another number is y.
A rational number is a fraction that can be expressed in the form of x/y.
A rational number between x and y is given by :
[tex]R=\dfrac{x+y}{2}[/tex]
So,
If x and y are two rational numbers such that x < y , then [tex]\dfrac{x+y}{2}[/tex] is a rational number in between x and y.

Answer:
a=7
Step-by-step explanation:
These two angles are complementary and the sum of their measures is 90°.
Therefore, we can create the equation: (5a+3)+52=90.
1. combine like terms. the equation becomes 5a+55=90.
2. -55 to both sides of the equation. the equation becomes 5a=35.
3. /5 to both sides of the equation. we can reach the conclusion that a=7
You might need: Find the area of a circle with a circumference of 12.56 units.
Answer:
The area is 12.56 units^2 (same as circumference?)
Step-by-step explanation:
Assuming pi is 3.14, the equation for the circumference is C = 2 pi r
Fill it out for the radius (r)
12.56 = 2 3.14 r
12.56 = 6.28 r
r = 2
With the radius, the equation for the area is A = pi r^2
Fill it out for the area
A = 3.14 2^2
A = 3.14 4
A = 12.56
Rewrite the equation by completing the square. x^{2}+4x-21 = 0

Ops gets $140 per day and laborers get $100 per day. If 35 people were hired and payroll was $4820, how many ops were employed and how many laborers?
Answer:
2 laborers and 33 ops
Step-by-step explanation:
Given
Let:
L = Laborers
P = Ops
From the statements, we have:
[tex]L + P = 35[/tex] -- total people hired; and
[tex]140P + 100L = 4820[/tex] ---number of hirees
Required
Solve for L and P
Make L the subject in: [tex]L + P = 35[/tex]
[tex]L = 35 - P[/tex]
Substitute [tex]L = 35 - P[/tex] in [tex]140P + 100L = 4820[/tex]
[tex]140P + 100(35 - P) = 4820[/tex]
[tex]140P + 3500 - 100P = 4820[/tex]
Collect like terms
[tex]140P - 100P = 4820 - 3500[/tex]
[tex]40P = 1320[/tex]
Solve for P
[tex]P = 1320/40[/tex]
[tex]P = 33[/tex]
Substitute [tex]P = 33[/tex] in [tex]L = 35 - P[/tex]
[tex]L = 35 - 33[/tex]
[tex]L = 2[/tex]

Thermometer A shows the temperature in the morning. Thermometer B shows the temperature in the evening. What is the difference in the temperatures?
Answer:
(Thermometer B reading - Thermometer A reading)
Step-by-step explanation:
The thermometer reading aren't given in the question.
However, hypothetically.
The difference between two temperature values (morning and evening values) would be :
Temperature in the evening - morning temperature
Therefore,
If ;
Thermometer A reading = morning temperature
Thermometer B reading = evening temperature
Difference in the temperature :
(Thermometer B reading - Thermometer A reading)
Three cylinders have a height of 8cm. Cylinder 1 has a radius of 1cm. Cylinder 2 has a radius of 2cm. Cylinder 3 has a radius of 3cm. Find the volume of each cylinder.
Answer:
Volume of Cylinder 1 = π×r×r×h
= 22÷7×1×1×8
= 25.13cm
Volume of Cylinder 1 = π×r×r×h
= 22÷7×2×2×8
= 100.53cm
Volume of Cylinder 1 = π×r×r×h
= 22÷7×3×3×8
= 226.19cm
help please, what does A equal??
============================================================
Explanation:
Refer to the diagram below. I've added the variables b, c and d to the drawing you posted.
The variable b is an inscribed angle, while variables c and d are arc measures.
For any inscribed quadrilateral, the opposite angles always add to 180. They are supplementary angles. This means the 110 degree angle and the angle b add to 180, so,
110+b = 180
b = 180-110
b = 70
Inscribed angle b is 70 degrees.
Next, we apply the inscribed angle theorem. This theorem says that the inscribed angle doubles in value to get its corresponding central angle measure (and therefore it's arc measure as well).
In other words, inscribed angle b = 70 doubles to 2*70 = 140 degrees. This represents the combination of arcs c and d. Therefore, c+d = 140. Note how inscribed angle b cuts off this longer arc.
We don't need to find the measure of arc c or arc d individually. We just need to find the measure of arc 'a'.
The four arc measures (161, a, c and d) all combine to a full 360 degree circle. Let's add those four parts, and set that equal to 360. We'll keep in mind that c+d = 140 as well.
So...
a+c+d+161 = 360
a = 360-161 - (c+d)
a = 360-161 - (140) ..... replaced "c+d" with "140"
a = 59
Arc 'a' is 59 degrees
Si restamos 10 unidades al cuadrado de un número, el resultado coincide con el triple de dicho numero. ¿Cual es el numero busado?
Answer:
The value of x is 5 that represents the searched number
Step-by-step explanation:
Let us assume x be the number [^ 2] i.e. squared.
Now
x^2 -10 = 3x
This is a quadratic equation
x^ 2 - 3x - 10 = 0
x^2 - 5x + 2x - 10
x (x - 5) + 2(x - 5)
(x-5) (x + 2) = 0
x - 5 = 0 where x = 5 positive.
x + 2 = 0 where x = -2 negative.
Here we considered the positive
The value of x is 5 that represents the searched number

What is an arithmetic sequence?This is a type of sequence which have common difference between each term. It is represent mathematically as:
Tₙ = a + (n – 1)d
Where
Tₙ is the nth term
a is the first term
n is the number of terms
d is the common difference
How to determine the relationship between the sequences Sequence 1: 1, 2, 3, 4, 5 Sequence 2: 10, 20, 30, 40, 50Relationship =?Relationship = sequence 2 / sequence 1
For the 1st term Sequence 1 = 1Sequence 2 = 10Relationship =?Relationship = sequence 2 / sequence 1
Sequence 2 / sequence 1 = 10 / 1
Cross multiply
Sequence 2 = 10 × sequence 1
For the 2nd term Sequence 1 = 2Sequence 2 = 20Relationship =?Relationship = sequence 2 / sequence 1
Sequence 2 / sequence 1 = 20 / 2
Sequence 2 / sequence 1 = 10 / 1
Cross multiply
Sequence 2 = 10 × sequence 1
If we continue with the pattern above, we'll discovered that
Sequence 2 = 10 × sequence 1
Thus, we can conclude that:
Each term in the second sequence is 10 times the corresponding term in the first sequence.
