Answer:
The last expression.
Step-by-step explanation:
The last expression is not a polynomial because x is in the denominator of the second term.
Answer:
[tex]4x^2+\frac{5}{x} -6[/tex]
Step-by-step explanation:
A rule for polynomials, is that if they have variables, the powers should be positive whole numbers. Basically, this means you cannot divide by a variable, but in option 4, second term, you are dividing 5 by x, which is the same as[tex]5*x^{-1}[/tex]. This means you are not raising the variable to a positive power, which means the whole 4th option is not a polynomial.

Answers
Answer:
3, 20, 2, and 2.5
Step-by-step explanation:
For each question, they gave you an x and y value. If you substitute them into the equation and then solve for k, you get your answer.
On the first one, x is 12 and y is 1/4. If you put those into the equation they gave you y = k/x, you get 1/4 = k/12
3/12 is 1/4 so the first k is 3.
Second one y = k/x. x is 4 and is 5. So 5 = k/4
20/4 is 5, so the second k is 20.

Answers
Answer:
51°
Step-by-step explanation:
An inscribed angle is half of the arc it intercepts. This means that arc QR is twice m<QTR or 78°.
Since <QSR is a central angle, it equals the arc it intercepts. This means m<QSR equals arc QR which is 78°.
We can say that QS equals to RS because they are both radii, and radii of the same circle are equal. This means triangle QSR is isosceles.
Let <QRS equal x. Because of base angle theorem, <SQR would also be equal to x. Since the angles in a triangle add up to 180, we can write an equation to model the situation:
m<QRS + m<SQR + m<QSR = 180
We can substitute the values we have:
x + x + 78 = 180
2x = 102
x = 51
Since <QRS is equal to x, it is 51°

Answers
Answer:
Yes, because its an rational number
Step-by-step explanation:
Solution: by division.
3/7 = 0.42857142857142857142…..
As you can see, the first six decimal places make a loop and become repetitive.
Then I proceeded to divide 100/6. That equals 16 remaning 4. Then counted four digits from0.428571. The 100th digit equals 5.

Step-by-step explanation:
distance formula is the square root of x sub 1 - x sub 2 quantity squared +y sub 1 + y sub 2 quantity squared. In this case it would look like the square root of (8-2)^2 +(9-1)^2. this would simplify to the square root of 100, which is 10.

It costs $45 for 3 xylophones and 3 yo-yo's. If you purchased 5 xylophones and
6 yo-yo's, it would cost $80. Set up a system of equations and solve for the
cost of a single xylophone and a single yo-yo.
Answers
Step-by-step explanation:
xylophone : x
yo-yo : y
3x + 3y = 45 —(1)
5x + 6y = 80 —(2)
(1)*2 : 6x + 6y = 90 —(3)
(3)-(2):
6x + 6y = 90
-(5x + 6y) = 80
x =10 — (4)
Sub (4) into (1)
3(10) + 3y = 45
30 + 3y = 45
3y = 45-30
y = 15/3
y = 5

Perimeter of ΔABC = 16.46 units
Step-by-step explanation:
By applying cosine rule (CAH) in the given triangle ADB,
cos(∠BAC) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(55°) = [tex]\frac{3}{AB}[/tex]
AB = 5.23 units
Since, ΔABC is an isosceles triangle
AB = BC = 5.23 units
AD = DC = 3 units [Perpendicular drawn from a vertex of an isosceles triangle is a perpendicular bisector of the opposite side]
Therefore, AC = AD + DC = 6 units
Now perimeter of ΔABC = AB + BC + AC
= 5.23 + 5.23 + 6
= 16.46 units

Answer:
56.73 ft
Step-by-step explanation:
Given:
51° (angle)
73ft (hypotenuse)
With the given information use sin to determine the height of the kite.
sin51° = x/73
solve for x (height)
x= 73*sin51°
x= 56.73ft
