The graph of is given by,
Here given the function is
when , then it passes through the origin (0,0).
When
Since we know that, , then the function has maximum height at .
Again when , again the function is 0.
So clearly the function is the Oscillating function.
Using graphing calculator we get the graph of function ,

That's too much. you should just put it separate. most won't want to answer.
Answer:
(x,y)=(2,12).
Step-by-step explanation:
Let's find the answer using the given equations:
y1=5x+2
y2=-3x+18
Using the intersection method:
y1=y2 so:
5x+2=-3x+18
5x+3x=18-2
x=16/8=2
Using x=2 in the first equation we have:
y1=5*(2)+2=12
So, the answer is (x,y)=(2,12).
Let's check our answer:
y1=5x+2
12=5*(2)+2
12=12
y2=-3x+18
12=-3*(2)+18
12=12
Answer:
Step-by-step explanation:
To find the expected no of broken cabinets for each strategy.
If A transport all the furniture
Suppose X₁ = number of furniture A broken
X₁ follows a binomial with n = 3, p = 0.10
E(X₁) = np
E(X₁) = 3 × 0.1
E(X₁) = 0.3
If A transport two (2) cabinets & B transport one (1) cabinet
expected no. of the broken cabinet by A out of 2 is
= 2 × 0.1
= 0.2
Suppose X₂ denotes the no of broken furniture by B
E(X₂) = np
where n= 1 and p = 0.15
E(X₂) = np
E(X₂) = 1 × 0.15
E(X₂) = 0.15
Thus. the expected number of broken cabinets = 0.2 + 0.15 = 0.35
Answer: 1) B is correct, constant of variation is -2.
Step-by-step explanation:
1)
Direct variation states that a relationship between the two variables. we say y varies directly as x
i.e, or y =kx.................[1] ; where k is the constant of variation.
Given the equation:
Divide both sides by -4 we get;
Simplify:
.......[2]
On comparing equation [2] with [1] we get;
k = -2
