Which function has a range of {yly < 5}?
Alexeev081 [22]

Answer:

f(x) = -(x-4)^2 + 5

Step-by-step explanation:

The function f(x) = -(x-4)^2 + 5 is a quadratic function. Its graph looks like a parabola. The graph has a vertex of (4,5) and opens up downward.

Proving that f(x) = -(x-4)^2 + 5 \le 5 for all x:

x^2 \ge 0 \Rightarrow (x-4)^2 \ge 0 \Rightarrow -(x-4)^2 \le 0 \Rightarrow -(x-4)^2 + 5 \le 5.

In a class, the ratio of girls to boys is 2:3. If there are 30 students in the class, what is the number of boys?
loris [4]
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys

Triangle inequality theorem-are the lengths 7, 4, and 2 of a triangle possible?
kakasveta [241]

You can't make a triangle with those lengths for sides.

The way I look at it is like this:

-- Take  2  sticks ... lengths  4  and  2  ... and connect them together at one end.

-- The farthest they can reach, if they're opened up completely and pointing
in opposite directions, is a distance of  6 .

-- They can't reach the ends of a stick that is  7  long.  So you can't make
a triangle with those  3  sticks.

spayn [35]

Answer:

1. Yes

2. No

2. Yes

4. Yes

5. Yes

Step-by-step explanation:

The angles in the first pair are congruent and 40° each (XYZ and XYW are complementary)

Segment FG is 4 cm while segment DE is 6 cm so they are not congruent

As shown on the figure both segment OR and segment OS is 2 in. long

Angle 2 and angle 4 are congruent

Angle ROQ and angle ROP are congruent because all angles shown on the figure has a measure of 90°
