Step-by-step explanation:
If the zeros are 5 and 9, then the equation will have the form:
y = a (x–5) (x–9)
We know the point (0, 90) is on the curve, so we can use this to find the coefficient a:
90 = a (0–5) (0–9)
90 = 45a
a = 2
y = 2 (x – 5) (x – 9)
Answer:
B
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2
(F is faces, V is vertices and E is edges )
Here F = 6 and E = 12, thus
6 + V - 12 = 2, that is
V - 6 = 2 ( add 6 to both sides )
V = 8 → B
Answer:

Step-by-step explanation:
3|−5| − 2|−2|
Absolute value means take the non-negative value
3 * 5 -2 * 2
