What is the rang y=-x2 - 2x + 3?​
Damm [24]

This is a downward facing parabola, so its range comes in the form

(-\infty, m) where m is the y coordinate of the vertex of the parabola.

We can find the x coordinate of the vertex using

x=-\dfrac{b}{2a}=-\dfrac{-2}{-2}=-1

And if we plug -1 in the equation we get the y coordinate of the vertex:

y=-(-1)^2-2(-1)+3 = -1+2+3=4

So, the range is the interval

(-\infty, 4)

What is the meaning of a composite number?
zaharov [31]
Composite number is a positive integer that can be formed by multiplying together two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2] Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.

For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself

seraphim [82]

Answer:

915 in²

Step-by-step explanation:

The area of the rectangle :

Length = 32 inches

Width = 25 - (10+10) = 25 - 20 = 5 inches

Area of rectangle = Length * width

Area = 32 * 5 = 160 in²

Area of triangle :

Base = 25 inches

Height = (46 - 32) inches = 14 inches

Area of triangle = 1/2 * base * height

Area of triangle = 1/2 * 25 * 14 = 175 in²

Total area = (160 + 175)in² = 335 in²

Total area of cardboard :

50 inches * 25 inches = 1250 in²

Amount of cardboard not used :

(1250 - 335) in² = 915 in²
