4. y = -x^2 + 4x + 12
5. y = 2x^2 + 12x + 18
6. y = 5x^2 - 3x - 8
Answer: 4) (-2, 6)
5) (-∞, -3) U (-3, ∞)
6) (-∞, -1) U (8/5, ∞)
Step-by-step explanation:
Find the zeros.
When the a-value is positive, the curve will be positive to the left of the leftmost zero and to the right of the rightmost zero. + - +

4) y = -x² + 4x + 12
y = -(x² - 4x - 12)
y = -(x + 2)(x - 6)
0 = -(x + 2)(x - 6)
0 = x + 2 0 = x - 6 -- + --
x = -2 x = 6 ←------|-----------|--------→
-2 6
Positive Interval: (-2, 6)
5) y = 2x² + 12x + 18
y = 2(x² + 6x + 9)
y = 2(x + 3)(x + 3)
0 = 2(x + 3)(x + 3)
0 = x + 3 0 = x + 3 + +
x = -3 x = -3 ←---------|----------→

y = 5x² + 5x - 8x - 8
y = 5x(x + 1) - 8(x + 1)
y = (5x - 8)(x + 1)
0 = (5x - 8)(x + 1)

Step-by-step explanation:
A survey of 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise at night. Tara claims that 35:55, 45:80, and 20:65 are possible ratios from this data. Jim claims that 35:100, 45:100, and 20:100 are possible ratios from this data. Who is correct? Explain.
100 total people ... 35 exercise in the morning ... 45 in the afternoon ... and 20 at night
Jim is correct ...
35/100 is the ratio of people who exercise in the morning to total people.
45/100 is the ratio of afternoon exercisers to total people
20/100 is the ratio of night exercisers to total people
Answer: Jim is correct because 35:100, 45:100, and 20:100 are part-to-whole comparisons. There are other possible part-to-part ratios from the data.

Split it into two shapes a square and a triangle.
Square = 3 x 3 = 9
Triangle = 1/2 x base x height
The height would be the side of the square = 3
The base would be the length of the top line minus the length of the side of the square = 7-3 = 4
1/2 x 4 x 3 = 6
Total area = 6 + 9 = 15 square units.
Answer:
15 sq. unitsStep-by-step explanation:
area of a trapezoid = (a + b) * h/2
where a = 3, b = 7, h = 3
plugin values into the formula:
A = (3 + 7) * (3/2)
A = 15 sq. units.

In an article about disinflation, various investments were examined. The investments included stocks, bonds, and real estate. Suppose that a random sample of 200 rates of return on real estate investments was computed and recorded. Assuming that the standard deviation of all rates of return on real estate investments is 2.25%, estimate an interval for the mean rate of return on all real estate investments with 95% confidence
Interpret the estimate.
Answer:
Step-by-step explanation:
Using the formula for calculating the confidence interval to estimate an interval for the mean rate of return on all real estate investments with 95% confidence;
Confidence Interval = xbar±(Z*S/√n)
xbar is the mean = 20%(assumed since we are not given)
n is the sample size = 200
S is the standard deviation = 2.25%
Z is the Z score at 95% confidence interval = 1.960
Confidence Interval = 20±(1.96*2.25/√200)
Confidence Interval = 20±(1.96*2.25/14.14)
Confidence Interval = 20±(1.96*0.159)
Confidence Interval = 20±0.312
Confidence Interval = (20-0.312, 20+0.312)
Confidence Interval = (19.688, 20.312)
Hence the interval for the mean rate of return on all real estate investments with 95% confidence is 19.688<x<20.312.
This means that the minimum rate of return on investment is 19.688% and the maximum rate of return on investment is 20.312%.(assuming 20% as the mean)

A recipe for salad dressing requires oil abd vinegar oil in a ratii of 3:2 which set of ingredients creates dressing with the same ratio?
Answer:
Step-by-step explanation:
Oil 3 parts in the basic relationship. So try 12
Vinegar 2 parts so call it x.
3/12 = 2/x Cross multiply
3x = 2*12 Combine the right
3x = 24 Divide by 3
3x/3= 24/3
x = 8
So 12:8 is the same as 3:2

If [tex]y=f(x)[/tex] is a one-to-one function, then it has an inverse such that [tex]f^{-1}(y)=x[/tex]. This means that [tex]f^{-1}(f(x))=x[/tex].
According to the table, [tex]f(1)=-2[/tex]. So by definition of the inverse, we have
[tex]f(1)=-2\implies f^{-1}(f(1))=f^{-1}(-2)\implies\boxed{1=f^{-1}(-2)}[/tex]
so the answer is either B or D (they're both the same...)

What are the coordinates of the image of vertex R after a
reflection across the y-axis?
O (4,3)
O (4, -3)
0 (-3,-4)
O (3, 4)
Answer:
D
Step-by-step explanation:
The coordinates of the image of vertex R after a reflection across the y-axis is (4,-3), the correct option is B.
What is a reflection?A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure. Consider a plane. Consider a design or shape on that plane. Now consider an axis.
If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.
We are given that;
The vertex R=(-4,-3)
Now,
When reflecting a point across the y-axis, the x-coordinate changes its sign, while the y-coordinate remains the same. Therefore, the image of vertex R(-4,-3) after reflection across the y-axis would be the point (4,-3), since its x-coordinate changes its sign and its y-coordinate stays the same.
Therefore, by reflection the answer will be (4,-3).

1. There are 60 players on a football team.
2/3
of the players are offensive players.
1/12
of the players are special teams players.
The remaining players are defensive players.
Each team member is either offensive, defensive, or special teams player. How many players are defensive player?
Answer:
3/12 players are defensive
Step-by-step explanation:
have to change demonitar to 12 so 3x4=12 so 2x4= 8
then 8+1=9 so 9/12
then 9-12=3 so 3/12 is the amount of defensive players
Which graph shows rotational symmetry?
10.9 + (-15.6) + 2.1 write as a decimal
Answer:
-2.6
Step-by-step explanation:
10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6
Therefore the answer is -2.6
The value of the expression 10.9 + (-15.6) + 2.1 will be negative 2.6.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The decimal number is the sum of a whole number and part of the fraction number. The fraction number is greater than zero but less than one.
The expression is given below.
⇒ 10.9 + (-15.6) + 2.1
⇒ 10.9 - 15.6 + 2.1
⇒ 13 - 15.6
⇒ - 2.6
The value of the expression 10.9 + (-15.6) + 2.1 will be negative 2.6.
