Answer:
<em>y = - 4x + 38 </em>
Step-by-step explanation:
A(3, 9)
B(5, 1)
= 
= - 4
CD║AB
C(9, 2)
y - 2 = - 4(x - 9)
<em>y = - 4x + 38</em>
Answer:
$105
Step-by-step explanation:
assuming that it costs $35 dollars for renting 1 kayak per day:
3 * 35 = k 3 is for the # of kayaks and 35 is the cost
105 = k multiply 35 w/ 3 to get the answer
Answer:
14.4km
Step-by-step explanation:
<h2>Speed = distance / time </h2>
- speed = 4.8 km/h
- time = 3 hrs
- distance = ?
Distance = speed * time
Distance = 4.8 * 3 = 14.4km
Answer:
(i) (f - g)(x) = x² + 2·x + 1
(ii) (f + g)(x) = x² + 4·x + 3
(iii) (f·g)(x) = x³ + 4·x² + 5·x + 2
Step-by-step explanation:
The given functions are;
f(x) = x² + 3·x + 2
g(x) = x + 1
(i) (f - g)(x) = f(x) - g(x)
∴ (f - g)(x) = x² + 3·x + 2 - (x + 1) = x² + 3·x + 2 - x - 1 = x² + 2·x + 1
(f - g)(x) = x² + 2·x + 1
(ii) (f + g)(x) = f(x) + g(x)
∴ (f + g)(x) = x² + 3·x + 2 + (x + 1) = x² + 3·x + 2 + x + 1 = x² + 4·x + 3
(f + g)(x) = x² + 4·x + 3
(iii) (f·g)(x) = f(x) × g(x)
∴ (f·g)(x) = (x² + 3·x + 2) × (x + 1) = x³ + 3·x² + 2·x + x² + 3·x + 2 = x³ + 4·x² + 5·x + 2
(f·g)(x) = x³ + 4·x² + 5·x + 2
Answer:
9.1
Step-by-step explanation:
