Answer:
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.
Step-by-step explanation:
Step-by-step explanation:
Right angle = 90°
(x + 3) + (x - 1) + (x + 1) = 90
3x + 3 = 90, x = 29.
Supplementary angles = Angles that add up to 180°.
x + (x + 104) = 180
2x = 76, x = 38.
<span>Pythagorean triple
a^2 + b^2 = c^2
so
5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169
answer is D. last one 5, 12 , 13</span>
Answer:
10)$38.50
11)D
Step-by-step explanation:
10) n = no. of rides
f(n) + g(n) = 1 + 2.5n
when n=15, 1 + 2.5(15)
= $38.50
11)f(x) = 4x³+3x²-5x+20
g(x) = 9x³-4x²+10x-55
(g-f)(x)=9x³-4x²+10x-55-(4x³
+3x²-5x+20)
= 9x³-4x²+10x-55-4x³
-3x²+5x-20
= 5x³-7x²+15x-75
