what two numbers multiply to -8 and add to -4
Answer:
-2-2√3, -2+2√3
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:
x(-4-x) = -8
-4x -x^2 = -8 . . . . . eliminate parentheses
x^2 +4x = 8 . . . . . . multiply by -1
x^2 +4x +4 = 12 . . . add 4 to complete the square
(x +2)^2 = 12
x +2 = ±√12 = ±2√3
x = -2±2√3
The two numbers are -2-2√3 ≈ -5.4641, and -2+2√3 ≈ 1.4641.
To find two numbers that multiply to -8 and add to -4, we can guess and check until we find a pair that satisfies both conditions. The two numbers in this case are -4 and 2.
Explanation:
The question is asking for two numbers that, when multiplied together, equal -8 and, when added together, equal -4. This falls under the category of quadratic equations. To solve this problem, we would typically use the formula "x = [ -b ± sqrt(b² - 4ac) ] / 2a", but in this case, it's easier to guess and check numbers. The two numbers that satisfy the conditions are -4 and 2. Their multiplication gives us -8 (-4*2) and their addition gives us -4 (-4+2).

B.If a is between 0 and 1, the image of the polygon is congruent to the polygon.
C.If a is greater than 1, the image of the polygon is smaller than the polygon.
D.If a is between 0 and 1, the image of the polygon is smaller than the polygon.
9514 1404 393
Answer:
D. If a is between 0 and 1, the image of the polygon is smaller than the polygon.
Step-by-step explanation:
The given transformation represents a dilation by a scale factor of 'a'. Every linear dimension of the image polygon will be a factor of 'a' times the corresponding dimension of the original.
When a > 1, the image is larger.
When a = 1, the image is congruent to the original (no sizes have changed).
When 0 < a < 1, the image is smaller. This description matches choice D.
The correct answer is D. If a is between 0 and 1, the image of the polygon is smaller than the original polygon.
Given that a polygon is graphed on a coordinate grid with (x, y) representing the location of a certain point of the polygon.
The polygon is transformed using the rule (x, y) → (ax, ay).
We need to determine the possible result of the transformation.
When a transformation rule (x, y) → (ax, ay) is applied to a polygon on a coordinate grid, the value of a determines the scaling factor of the image.
If a is greater than 1, the image of the polygon will be larger than the original polygon because the coordinates are multiplied by a value greater than 1, resulting in an expansion or enlargement of the shape.
If a is between 0 and 1, the image of the polygon will be smaller than the original polygon because the coordinates are multiplied by a value between 0 and 1, resulting in a contraction or reduction of the shape.
Therefore, statement D is correct.

Choose one type of power plant. Describe how electricity
is generated at this type of plant.
Answer:
Let's us talk about the Hydro Power Plant that generates electricity by energy possessed in a mass of flowing water by virtue of it height.
Step-by-step explanation:
The hydo power plant utilizes
an hydraulic turbine which converts the energy of flowing water into mechanical energy of it rotating shaft . A hydroelectric generator (alternator) converts this mechanical energy into electricity. The operation of this alternator is based on the principles of Electro magnetic induction, that when a coil of conductor is moved past a magnetic field, it causes electricity generation. So when high energy water impinges on the blade of a turbine the energy is transformed to rotational motion of the shaft which is connected to the the alternator
When the alternator turns, coils attached to it move past the magnetic field hence this causes electricity to flow and a voltage to develop at the generator output terminals."
Answer:
Sample Response: Power plants generate electricity by turning a turbine. The turbine spins a generator, which produces electricity. Fossil fuels are burned to heat water, producing steam that turns the turbine. Nuclear power plants use fission to produce the thermal energy needed to produce steam. Wind and falling water are also used to turn turbines, which spin generators that produce electricity.

A spinner is divided into four colored sections that are not of equal size: red blue purple and orange Orange : 9 red 15 blue 24 purple 12 based on these results what is the probability that the arrow will land on the purple section
Final answer:
The probability that the arrow will land on the purple section of the spinner is calculated by dividing the number of purple results (12) by the total number of results (60), resulting in a probability of 1/5 or 20%.
Explanation:
The question is asking about the probability of the arrow landing on the purple section of a spinner with four different colored sections (orange, red, blue, and purple), each with a different number of results (orange: 9, red: 15, blue: 24, purple: 12). To calculate this probability, you need to use the basic probability formula which is:
Probability of an event = (Number of ways the event can occur) / (Total number of possible outcomes)
So the probability that the arrow will land on the purple section is:
Probability of purple = Number of purple results / Total results = 12 / (9 + 15 + 24 + 12) = 12 / 60 = 1 / 5
Therefore, the probability is 0.2, or 20%.

12. The surface area of the soup can below is 51.84 in. If the
diameter of the can is 3 inches, find the height of the can.
Given: r=1.5
Given: 51.84=2pi(1.5)(h)+2pi(1.5squared)
Answer:
The height of the can is 4 inches.
Step-by-step explanation:
Cylinder:
It is a three dimension shape.The lateral surface area is = 2πrh, r= radius, h= height.The total surface area is= (2πrh+2πr²)=2πr(r+h)The volume is = πr²h.Given that, the surface area of the soup can is 51.84 in².
The diameter of the can is 3 inches.
Then, radius of the can [tex]=\frac{Radius}{2}[/tex]
[tex]=\frac32[/tex] inches
=1.5 inches
Total surface area of the cone is = 2πrh+2πr²
[tex]=2\pi (1.5)h+2\pi (1.5)^2[/tex] in².
[tex]=2\pi (1.5)(h+1.5)[/tex] in².
=3π(h+1.5) in².
So,
3π(h+1.5)=51.84
[tex]\Rightarrow (h+1.5)=\frac{51.84}{3\pi}[/tex]
[tex]\Rightarrow h=\frac{51.84}{3\pi}-1.5[/tex]
⇒h=5.5-1.5
⇒h=4 inches
The height of the can is 4 inches.

The most likely indication of an association between gender and favorite meal to cook is if C) the value of B is not similar to the value of C, suggesting a significant difference in meal preferences among males for lunch and dinner.
To determine if there is an association between gender and a person's favorite meal to cook, we need to compare the conditional relative frequencies.
The value of A is similar to the value of B means that the percentage of males who prefer cooking breakfast is similar to the percentage of males who prefer cooking lunch. If these values are similar, it suggests that the meal preference might not be strongly associated with gender.The value of A is similar to the value of E implies that the percentage of males and females who prefer cooking breakfast are similar. This would suggest a possible lack of association as well.The value of B is not similar to the value of C means that a significant difference exists between males preferring lunch and males preferring dinner. This variation could indicate a potential association between gender and meal preference.The value of B is not similar to the value of F implies a difference between males preferring lunch and females preferring lunch. A difference here would suggest an association between gender and the preference for lunch.Since we are looking for an indication of association, the most likely scenario would be that c) the value of B is not similar to the value of C.

How many unique triangles can be drawn with side lengths 12 cm and 16 cm and a 50 ° included angle
Final answer:
Using the Law of Cosines with the given sides and angle, we find that only one unique triangle can be drawn since a specific third side length can be determined, allowing only one possible triangle to exist.
Explanation:
To determine how many unique triangles can be drawn with side lengths of 12 cm and 16 cm and an included angle of 50°, we use the concept of triangle construction. The Law of Cosines allows us to find the range of possible third sides that could form a triangle:
c² = a² + b² - 2ab*cos(C),
where:
c is the unknown side length,a and b are the known side lengths (12 cm and 16 cm), andC is the included angle (50°).The solution to this equation will determine if we have a single unique triangle, more than one triangle, or no triangle at all. In this case:
c² = 12² + 16² - 2*12*16*cos(50°)
Calculating the value, we can then check if 0 < c < 28 (because for a triangle to exist, the sum of any two sides must be greater than the third side). If the third side falls within this range, a unique triangle can be drawn. As a triangle with two sides and an included angle will only yield one possible third side length, there can be only one unique triangle formed.
So, the answer is that with the given two sides and included angle, only one unique triangle can be drawn.
