What is a Polynomial?A polynomial is an expression consisting of variables, exponents, and coefficients of the variables joined by a plus or minus sign.
The expression is
7-√5
If this expression is a root of a polynomial, and 7+√5 is the root of the same polynomial then the radical is called radical conjugate.
A radical conjugate is an expression in which is there is at least one radical term, which is the same to the other expression with the same two terms and different signs.

An airplane flies 56 miles due north and then 33 miles due east. How many miles is the
plane from its starting point?
Answer:
65 miles
Step-by-step explanation:
using the Pythagorean theorem:
56²+ 33² = d²
d² = 4225
d = 65 miles
The distance of the plane from the starting point will be 65 miles. Distance or the displacement in the given case is found by the phythogorous theorem.
What is the distance?Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
An airplane flies 56 miles due north and then 33 miles due east.
The distance can be found with the help of the phythogorous theorem. The following calculation is done.
[tex]\rm AB^2+BC^2=AC^2 \\\\\rm (56)^2+(33)^2=AC^2 \\\\AC=65 \ miles[/tex]
Hence the distance of the plane from the starting point will be 65 miles.

1. The cross section of an A-frame cottage is an isosceles triangle. If the
slope of one of the sides is 1.8 and it is 19 feet high at the peak, what angle
does the side make with the horizontal? What is the width of the cottage?
Answer:
21.12
Step-by-step explanation:
To solve this, it's best to use Cartesian planes. So we draw it in the Cartesian planes. From the question, we have {0, 19} and also {1.8, 0}.
If x = -1.8 and x = +1.8, then
1.8 = (19 - 0) / (0 - x)
1.8 = 19 / -x
x = -19 / 1.8
x = -10.56
Since we're having it in 2 quadrants then, we have 10.56 + 10.56 = 21.12 to be our width of the cottage

Jerissa has 5 pink bows, 2 blue bow, and 4 purple bows in a box. She will randomly choose 1 bow from the box. What is the probability Jerissa will choose a purple bow?
Answer:
[tex]\frac{4}{11}[/tex] or 36%
Step-by-step explanation:
Probability = number of favourable outcomes / total number of outcomes
The number of favourable outcomes is 4 because we know that there are 4 purple bows
The total number of outcomes is 11 because 5 + 2 + 4 = 11
Our equation becomes Probability = [tex]\frac{4}{11}[/tex] which is 36%
Answer:
4/11
Step-by-step explanation:
you add all the bows together to get the whole witch is 11 and she has 4 purple bows. so there is a 4 out of 11 chance she will draw a purple bow
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches. 2 triangular sides have a base of 10 inches and height of 5.6 inches. 2 triangular sides have a base of 5 inches and height of 7.1 inches.
Answer:
Answer:
a) The base of the rectangular pyramid shown has an area of
60 square inches
b) A triangular face with a base of 10 inches has an area of 28 square inches.
c) A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) The total surface area of the pyramid is 151.5 square inches.
Step-by-step explanation:
a) Solving for question a, we were given the following parameters
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches
The formula used to calculate the rectangular base of a rectangular pyramid =
Length × Width
Where :
Length = 10 inches
Width = 6 inches
Rectangular base = 10 inches × 6 inches
= 60 inches²
Hence, the base of the rectangular pyramid shown has an area of 60 square inches
b) Solving for question b, we have the following values given:
2 triangular sides have a base of 10 inches and height of 5.6 inches.
First step would be to solve for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (10 inches × 5.6 inches) ÷ 2
= 56inches² ÷ 2
= 28 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 28 inches².
A triangular face with a base of 10 inches has an area of 28 square inches.
c) Solving for question c, the following parameters are given:
2 triangular sides have a base of 5 inches and height of 7.1 inches.
We would be to solving for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (5 inches × 7.1 inches) ÷ 2
= 35.5 inches² ÷ 2
= 17.75 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 17.75 inches².
A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) Solving for d, it is important to note that, a rectangular pyramid has 5 faces and they are: The rectangular base and 4 triangular faces
The formula for the total surface area of the rectangular pyramid is given as
Total Surface Area of the rectangular pyramid = Rectangular Base + Area of Triangular Side A + Area of Triangular Side B + Area of Triangular Side C + Area of Triangular Side D + Area of Triangular Side E
Total Surface Area of the Rectangular Pyramid = 60 inches² + 28 inches² + 28 inches² + 17.75 inches² + 17.75 inches²
Total surface Area of the Rectangular pyramid = 151.5 inches²
The total surface area of the pyramid is 151.5 square inches.

Pizza by the Pan sold 4 dozen pizzas in the afternoon. That night, they sold 2.5 times as many pizzas as they did during the afternoon. How many pizzas did they sell in all that day?
Answer:
they sold 14 pizzas all day.
Step-by-step explanation:
4 x 2 = 8
0.5 means half of what they sold in the afternoon
4 ÷ 2 = 2
now add them both together to get the number of pizzas they sold at night.
8 + 2 = 10
now add the afternoon and night together
10 + 4 = 14
answer: 14 pizzas

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Price of boots= $80
Store A is offering a 25% discount off
= 80 x 25/ 100
= 80/4
= $20
So, price after discount = 80- 20 = $60
Store b is offering a $10 discount off
= 80- 10
= $70
Hence, Samuel will pay 10$ less if he buys the boots from Store A
