Answer:
B. XZ
Step-by-step explanation:
Let's go by order of elimination!
D. Cannot be determined is incorrect because in order to determine a side you need one angle. We have three therefore, this answer would make absolutely no sense!
As for the rest we must solve!
A. XY = 62° + 55°
B. XZ = 62° + 63°
C. YZ = 55° + 63°
Add them up and see which one is the greatest!
A. XY = 117°
B. XZ = 125°
C. YZ = 118°
After adding we can determine and prove that our answer is B!
Answer:
Part a) The drawn in the attached figure
Part b)The slant height of the outside edge is 
Step-by-step explanation:
Part a) The drawn in the attached figure
Part b) What is the slant height of the outside edge?
we have that
The diameter of the base of the cone is 12 in
so
----> the radius is half the diameter
Applying the Pythagoras Theorem find the slant height x
substitute the values
Number 7:
answer: a) odd
b) negative
explanation: let’s look at end behaviour. we know that all odd degree polynomials have opposite end behaviours, meaning that as x approaches negative infinity it will be in an opposite quadrant compared to when x is approaching positive infinity. Since x starts in Quad 2 and ends in Quad 4, we know it’s odd degree!! To figure out whether the leading coefficient is positive or negative, let’s look at what we already know about functions. Any odd function that has a positive leading coefficient will go from Quad 1 to Quad 3. Think about y = x^3 for example. Since this function goes from 2 to 4, the L.C. is negative.
number 8:
answer: a) even
b) negative
explanation: same logic as above but with even degree functions. Think about y = x^2 or x^4
