Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
Answer:
x+8
Step-by-step explanation:
144-24 =120
120/15=8
x=8
a) Local maximum values of g are: 0 and 3
b) The values at which g has local maximum are : -2 and 2
<h3>What is a maximum point?</h3>
A maximum point is the point at which the gradient of the curve changes from positive to negative.
Analysis:
The inverted v-curves all have maximum values and they are two.
The one at x = -2 and the one at x = 2 for in both cases their maximum values are y = 0 and y = 3 respectively.
