The total surface area of this prism is 480.
Answer:
The measure of m∠KNY is;
(D) 105°
Step-by-step explanation:
From the diagram, we have;
The given angle at the circumference = The The angle the arcs makes at the center of the circle
From circle, theorem, angle subtended at the center = Twice the angle subtended at the circumference
Therefore;
Angle ∠D and angle ∠Y = 90°/2 = 45°
Angle ∠O and angle ∠K = 60°/2 = 30°
From angle summation theorem, we have;
m∠KNY + ∠K + ∠Y = 180° (The sum of the interion angles in ΔYNK
∴ m∠KNY = 180° - (∠K + ∠Y)
Plugging in the known values of ∠K and ∠Y gives;
m∠KNY = 180° - (30° + 45°) = 105°
m∠KNY = 105°.
The answer is quadratic.
A quadratic equation takes this form:
<em>ax^2+ bx + c</em>
The "a,""b,"and "c" represent numerical coefficients.
This is how your equation looks:
3x + x^2 + 4
Now it is standard that we organize the polynomial in descending order so it will look like this:
x^ 2 + 3x + 4
(commutative property of addition says that the arrangement will not affect the result)
It matches the quadratic polynomial form.
<em>* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed. </em>
