Answer:
the photo is blocked on my computer
Step-by-step explanation:
Negative rate of change just means the graph is falling. This one is falling everywhere after x=0.5. The only choice in that section of the graph is the last one.
What it's telling you to do is take the nth root of something raised to the mth power. Without the m, it would look like this.
Without the n it would look like this.
When they are put together, it looks like this.
Answer:
x=0.469396
Step-by-step explanation:
x−(−3x3−x2+1)=−3x3−x2+1−(−3x3−x2+1)
3x3+x2+x−1=0
Step 2: Use cubic formula.
x=0.469396
Answer:
255
Step-by-step explanation:
total cost paid = fixed cost + total variable cost
total variable cost = distance travelled x variable cost per unit
two equations can be derived from the question
a + 10b = 105 equation 1
a + 15b = 155 equation 2
a = fixed cost
b = variable cost per unit
Subtract equation 1 from 2
5b = 50
b = 10
Substitute for b in equation 1
a + 10(10) = 105
a = 105 - 100 = 5
a = 5
cost of travelling a distance of 25km
5 + 10(25) = 255
