Answer:
<em>quadratic trinomial</em>
Step-by-step explanation:
The degree is based on the highest exponent in the expression. Since the exponent is 2, this expression is quadratic.
The number of terms in this expression is 3. A term is separated by an operation like "+" or "-" :
Based on the number of terms, this expression is a trinomial.
When you are putting the bolded words together, the degree comes first, then the terms:

Answer:
f⁻¹(1/5) = 2
Explanation:
If f(x) = (2x -3)/5
To find inverse of f(x), make x the subject.
Then,
To find f⁻¹(1/5), simplify insert [x = 1/5 or 0.2]
which yields
The midpoint should be (3,-2)
Answer:
2
Step-by-step explanation:
When in doubt, have your calculator evaluate this.
___
The reference angle for 5π/3 is π/3. The angle is in the 4th quadrant, where the secant is positive.
sec(5π/3) = sec(π/3) = 1/cos(π/3) = 1/(1/2)
sec(5π/3) = 2
If you are needing to find the distance between the two points, you must use a simple formula, cleverly named, the distance formula. Since I can't input special characters into the answer box, I'll explain it the best I can.
( The square root of ( (x - x)^2 + (y - y)^2 ) )
First, we need to find the first x subtracted from the second x, as so:
(4,5) and (7,-9)
4 - 7 = -3
Now, we square the -3.
-3^2 =
-3 * -3 = 9
Next, we have to find the first y subtracted from the second y.
(4,5) and (7,-9)
5 - (-9) = 14
Now, we square the 14.
14^2 =
14 * 14 = 196
Let's see how the numbers fit in the formula:
sqrt((x - x)^2 + (y - y)^2)
sqrt((4 - 7)^2 + (7 - (-9))^2)
sqrt((-3)^2 + (14)^2)
sqrt( 9 + 196 )
This is where we currently are in the formula, all we have to do now is square root the total of 9 + 196.
sqrt( 9 + 196 )
sqrt( 205 )
The square root of 205 = 14.31782106...
There are a few answers you can consider:
1) sqrt(205)
2) 14.32 units
or
3) 14.31782106
Depending on the answer you desire, use the one that sounds the most correct to you. Although all three are correct, it may not be the answer you require.
