What are polynomials?Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
The power function is a polynomial. Given the energy, e, produced in a nuclear reaction is proportional to the mass, m. Therefore, we can write,

Marks obtained for 1 right answer = +3
Marks obtained for 1 wrong answer = −2
(i) Marks scored by Radhika = 20
Marks obtained for 12 correct answers = 12 × 3 = 36
Marks obtained for incorrect answers = Total score − Marks obtained for 12 correct answers = 20 − 36 = −16

Thus, number of incorrect answers = (−16) ÷(−2) = 8
Therefore, the number of incorrect answers made by Radhika = 8

1 soda + 1 cupcake+1popsicle=$22.00
1 soda +3cupcakes+3popsicle=$40.00
if a cupcake cost,$2:00 more than a popsicle,find the cost of the following
a)1 cupcake
b)1 popsicle
Answers
Answer:
a) 1 cupcake = $5.50
b) 1 Popsicle = $3.50
Step-by-step explanation:
Let s = cost of one soda
Let c = cost of one cupcake
Let p = cost of one Popsicle
From the given information we can create 3 equations:
Equation 1: s + c + p = 22Equation 2: s + 3c + 3p = 40Equation 3: c = p + 2Subtract Equation 1 from Equation 2 to eliminate the variable s:
s + 3c + 3p = 40
- s + c + p = 22
2c + 2p = 18
Substitute Equation 3 into this new equation and solve for p:
⇒ 2c + 2p = 18
⇒ 2(p + 2) + 2p = 18
⇒ 2p + 4 + 2p = 18
⇒ 4p = 14
⇒ p = 3.5
Substitute the found value of p into Equation 3 and solve for c:
⇒ c = p + 2
⇒ c = 3.5 + 2
⇒ c = 5.5
To find the cost of a soda (s), substitute the found values of p and c into Equation 1:
⇒ s + c + p = 22
⇒ s + 5.5 + 3.5 = 22
⇒ s = 13
Therefore,
1 soda costs $131 cupcake costs $5.501 Popsicle costs $3.50The measure of an angle is 153°. What is the measure of its supplementary angle?
Answers
Answer:
27
Step-by-step explanation:
Supplementary angles add up to 180 degrees
So to find the measure of an angle supplementary to a given angle, we simply subtract the given angle from 180
The given angle here has a measure of 153 degrees
So the angle's supplement has a measure of 180 - 153 = 27 degrees.

V= / Tr³

V≈ [?]cm³
Enter
10 cm.
Answers
Answer:
408 cm^3
Step-by-step explanation:
You have to find the volume of each object individually. You first find the volume of the sphere, so you input the radius, which is 3, into the equation which comes out to be 108 cm^3. You then have to find the volume of the cylinder, and since you have the diameter of the cylinder, and you need the radius, and the radius is half of the diameter, you would input 5 into the equation as the radius, since half of 10 is 5. That comes out to be 300 cm^3, so then you add the two volumes together, which is 408 cm^3
Harry Potter decides it’s too cold for him to stay in Hogwarts and wants to fly straight south. He is not sure where to point his broomstick, considering that the wind is pretty strong at 21 km/h [S 55° E]. His broomstick has an airspeed of 18 m/s. Determine the heading he should have and the velocity of the broom with respect to the ground.
Answers
Harry Potter decides it’s too cold for him to stay in Hogwarts and wants to fly straight south, the heading he should have and the velocity of the broom with respect to the ground are mathematically given as
VR = 20, 699 m/s South
What is the heading he should have and the velocity of the broom with respect to the ground?Divide horizontal and vertical components of Vs and Vw vectors
For Vs
Vs = Vs cos∅ [s] + Vs Sin∅ [w]
Vs = 18 Co58 [s] + 18 sin∅ [w]
For Vw
Vw = Vw Cos 55' [s] + Vw Sin 55 [E]
5.8333 x Cos 55 (s) + 5-8333 Sin 55 [E]
Vw = 3.3458 [s] + 4.7783 [E]
Resultant velocity VR = Vs + Vw
VR= 18 Coso (s) + 18 sine [w] +3.3458 (5) +42783 (E)
VR = (186030 +3.3458) [5] + (18sing - 4.7183)6]
(Harry Potter) flies south
18sin∅ - 4.7783 18=0
Hence
Sin∅ = 4.7783 18/18
∅ =sin{-1}(4.7783 18/18)
∅ = 15.3943
Harry Potter flies in the direction south to ∅ = $15.3943w]
Hence velocity
VR = (18 cos∅ + 35452) s + 0
VR = (17.3541 +3-3458) s
VR = 20, 69999 m/s South

Farmer Bob has pigs and chickens. He has 37 animals, and there are 124 legs among them altogether. How
many chickens does Bob have?
Answers
x + y = 37; 4x + 2y = 124
To save time, the answer to this system of equations is x = 25, and y = 12. Because pigs have four legs, this means there are 25 pigs (as represented in the system of equations) and there are 12 chickens because they each have two legs.
Your final answer: There are 25 pigs and 12 chickens.
Step-by-Step Explanation:
Let ‘x’ be the No. Of Chickens
Let ‘y’ be the No. Of Pigs
Total = 37 Animals
Total No. of Legs = 124
We know, a Chicken has 2 legs and a Pig has 4 legs.
Framing the Equations :-
=> x + y = 37 (Eq. 1)
=> 2x + 4y = 124 (Eq. 2)
Therefore, from Eq. 1 :-
x + y = 37
=> x = 37 - y (Eq. 3)
Substitute value of ‘x’ from Eq. 3 in 2 :-
2x + 4y = 124
2(37 - y) + 4y = 124
74 - 2y + 4y = 124
74 + 2y = 124
2y = 124 - 74
2y = 50
y = 50/2
=> y = 25
Substitute value of ‘y’ in Eq. 3 :-
x = 37 - y
x = 37 - (25)
=> x = 12
Therefore,
No. Of Chickens = 12
No. Of Pigs = 25
