Answer:
2 solutions
Step-by-step explanation: As we have seen, there can be 0, 1, or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b2 - 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.

For questions 5-9 list all the polygons shown that fit each description.If there could be no such polygon, explain why
Answer:
5. B, C and E
6. C
7. None
8. A and D
9. F and G
Step-by-step explanation:
See attachment for complete question
5. B, C and E
B, C and E are not parallelogram because they do not have 2 pairs of parallel sides
B and E are trapeziums while C is just a quadrilateral.
6. C
In (5) above, we established that B and E are trapeziums while C is not. This implies that only C is a quadrilateral.
7. None
A square is a parallelogram. So, it is not possible for a shape to be a square and not be a parallelogram.
8. A and D
A is a rhombus. D is a square and will be treated as a rhombus because all sides are equal.
9. F and G
These shapes have 2 pairs of parallel lines but all 4 sides are not equal; only the opposite sides are equal.

Two lines, a and b, are parallel. If both of the lines are rotated 90° in the same direction and then translated to the right by the same number of units, which statement about the lines resulting from these transformations is true? They will be parallel. They will be the same line. They will be perpendicular. They will intersect, but they won't be perpendicular.
Answer:
They will be parallel.
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Translation is the movement of a point up, down, left or right. Rotation is the turning of a point about a fixed point.
If two parallel lines a and b are rotated 90° in the same direction, they would still be parallel. If they are then translated to the right by the same number of units, they would still remain parallel to each other.
A cable that is 42 feet long is divided into lengths in the ratio 3:4. What are the two lengths into which the cable is divided?
Answer:
18 ft and 24 ft
Step-by-step explanation:
3:4
6:8
9:12
12:16
15:20
18:24, 18+24=42
The two lengths into which the cable is divided is 18 and 24.
Given that,
A cable that is 42 feet long is divided into lengths in the ratio 3:4.Based on the above information, the calculation is as follows:
The first length be
[tex]= 42 \times 3 \div (3 + 4)[/tex]
= 18
And, the second length be
[tex]= 42 \times 4 \div (3 + 4)[/tex]
= 24

1 Factor the polynomial over the set of real numbers. (a) f(x) = 25x^2 - 10x - 24
Answer:
(5x+4)(5x-6)
Step-by-step explanation:
[tex]25x^{2} -10x-24[/tex]
Separate into two parts, first realizing that the only two factor pairs for 25 are 5 and 5 or 1 and 25. Using 5 and 5 makes the most sense, so
(5x )(5x )
The other two numbers need to multiply to -24 and add up to -10.
Pairs that muliply to 24 could be 1 and 24, 2 and 12, 3 and 8, and 4 and 6. The more you factor the easier it will be to quickly discern which numbers to use. In this case, the right pair is 4 and 6. Because it needs to add up to -10, it should be 4 and -6 (because multiplying out, -30 + 20 = -10).
Thus, the final factored equation is (5x+4)(5x-6). You can check this by FOILing and making sure you get the original equation.
At midnight, the outside temperature is 10 degrees Fahrenheit. By 4:00 A.M., the temperature is -2 degrees Fahrenheit. Show the equation to determine the
average change in temperature per hour.
Answer:
its a change of -3 per hour.
Step-by-step explanation:
I do not know the formula for the equation you speak of, but the change per hour is that it is going down by 3 every hour. 10-3=7-3=4
4-3=1
1-3= -2.

Answer:
Area of a circle = πr²
Step-by-step explanation:
The formula used for obtaining the area of a circle denoted as A is : πr²
Where, π is taken as a 22/7 (constant)
r = Radius of the circle, which is half the diameter of the circle
Hence,
Area of a circle = πr²

A carton of ice cream has a radius of 11 cm and a height of 30 cm. A scoop of ice cream has a radius of 3 cm. How many cartons of ice cream should Ester order to make 100 scoops?
Answer:
1 carton
Step-by-step explanation:
The volume of the carton: ~11404 cm^3
The volume of 1 scoop: ~113.1 cm^3
100 scoops --> 113.1 x 100 = ~11310 cm^3
11310<11404 --> ester will need 1 carton because 100 scoops won't fill more than one.
