Answer:
Difference between algebraic expression and polynomial
Step-by-step explanation:
Algebraic expression:
- An algebraic expression is made up of variable, constants and arithmetic operators like addition, subtraction, etc.
Polynomial
- A polynomial is an expression consisting of variables and coefficients, that involves operations like addition, subtraction, multiplication.
- A polynomial cannot have negative exponential powers.
Difference between algebraic expression and polynomial
- All polynomials are algebraic expression.
- All algebraic expression cannot be polynomials.
- Polynomial must have no negative exponents.
- Polynomial does not have variable inside radical system.
ANSWER
B. 1
EXPLANATION
The given function is
This is a piece-wise defined function.
We want to find f(1)
We substitute x=1 into f(x)=x because, 1 belongs to the interval,
1≤x≤5
f(1)=1
The correct answer is B.
Answer:
<em>x = 10; y = 20</em>
Step-by-step explanation:
8x + y = 100 (alternate exterior angles are congruent)
4x + y = 60 (corresponding angles are congruent)
Subtract the second equation from the first equation.
4x = 40
x = 10
Substitute x = 10 in first equation and solve for y.
8(10) + y = 100
y = 20
Answer:
The three statements on the right hand side of the screen are the correct ones
Step-by-step explanation:
To take the average of the weight of the cat in the month of April is the following:
9.8 + 9.6 + 9.7 + 9.5 + 9.4 = 48
But then divide that by the number of samples:
48/5=9.6
The mean for April is 9.6
To take the average of the weight of the cat in the month of November is the following:
9.4 + 9.3 + 9.1 + 9.2 + 9 = 46
But then divide that by the number of samples:
46/5=9.2
Then, lastly, subtract the mean from November by the mean of April:
9.6-9.2=0.4
