Answer:
Increasing: -10<x<-8. 8<x<10. -2<x<0.
Deacresing: 3<x<7.
Neither Increasing nor decreasing: -8<x<-5
The answer is 16 inches.
Let r be a radius and h be a height of a cylinder
Since the cylinders are similar, then the ratio between their radiuses is equal to the ratio of their heights:
r1 : r2 = h1 : h2
Cylinder A:
r1 = 5.6 in
h1 = ?
Cylinder B:
r2 = 1.4 in
h2 = 4 in
5.6 : 1.4 = h1 : 4
h1 = 4 * 5.6 : 1.4
h1 = 16 inches
Answer:
8
Step-by-step explanation:
It's clear that the ratio of the weight and cost is 1:2.
So when you increase the factor by 4 , the cost increases by 8.
That's all I can say, and I'm sure my answer is correct.
Each number in the code can be 1 of 10 numbers.
The total number of possible combinations is 10 * 10 * 10 * 10 = 10,000
The probability of getting 1234 would be 1/10,000
