Chapter:- Triangle and it's properties
Using the Pythagorean Theorem, the values of x are given as follows:
First triangle: x = 12.Second triangle: x = 21.What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
Hence, in the first triangle:
x² + 35² = 37²
x² = 37² - 35²
x² = 144
x = sqrt(144)
x = 12.
On the second triangle, we have two right triangles, hence:
x = a + b.
a² + 8² = 10²
a² = 36
a = sqrt(36)
a = 6.
b² + 8² = 17²
b² = 225
b = sqrt(225)
b = 15.
Hence the value of x is given as follows:
x = a + b = 6 + 15 = 21.

A cannery processed 1,445 pounds of strawberries in 4.5 hours. The cannery processed 2,320 pounds in 7 hours. Write a linear equation to model the relationship between the weight of the strawberries S and time T. How many pounds of strawberries can be processed in 11 hours?
Answer:
S = 350T - 130, where T is the number of hours and S is the number of pounds.
If T = 11, then S = 3,720 pounds.
Step-by-step explanation:
[tex]m = \frac{2320 - 1445}{7 - 4.5} = 350[/tex]
[tex]2320 = 350(7) + b[/tex]
[tex]2320 = 2450 - b[/tex]
[tex]b = - 130[/tex]
So we have S = 350T - 130. Substituting 11 for T, we have S = 3,720 pounds.
The formula for the Ideal Gas Law is P V=n R T , where P is the pressure in kilopascals ( kPA), V is the volume in liters (L), T is the temperature in Kelvin (K), n is the number of moles of gas, and R=8.314 is the universal gas constant.
a. Write an equation to find the volume in terms of P, n, R , and T .
The equation to find the volume in terms of P, n, R , and T is:
[tex]V=\frac{n R T}{P}[/tex]
What is Ideal Gas Law?The ideal gas law is the general gas equation. It is a good approximation to find behavior of gases under different conditions. This law says that the product of pressure in the atmosphere and volume is equal to product of moles and temperature. We generally use an equation to define these relations.
Equation of ideal gas law
P V=n R T
where,
P = pressure measured in atmosphere
V = volume measured in liters
n = number of moles present in gas
T = temperature
R = gas constant
Ideal gas equation shows several direct and indirect variations between the different elements , such as in the equation pressure (P) shows direct variation with n and T , and inverse variation with volume (V).

Suppose the cost of an item is c. First, the cost is discounted by 30%. Then sales tax of 6.5% is added to the sales price. Write an algebraic expression for the final cost of the item using the variable c.
The Algebraic expression for the final cost of the item using the variable c is 0.7455c
The cost of the item is c
Algebraic expression after discounting the cost by 30%
c - 30%of c
c- 0.3c
0.7c
Now, Algebraic expression after the application of 6.5% of sales tax
0.7c + 6.5%of 0.7c
0.7c +0.065(.7c)
0.7c +0.0455c
0.74.55c
Hence, 0.7455c is the algebraic expression for the final cost of the item using the variable c.

The cross-section of a lean-to shelter is in the shape of a triangle. The base of the triangle is 66 feet more than twice its height. If the area of the triangle is 108108 square feet, determine the length of the base and the height of the triangle in feet
A triangle with an area of 108 square feet has a base length and height equal to 24 feet and 9 feet, respectively.
Given that the cross-section of the lean-to shelter is in the shape of a triangle, its area is the area of a triangle.
A = 1/2bh
where b is the length of the base
h is the height
If the base of the triangle is 6 feet more than twice its height, then we have b = 6 + 2h.
A = 1/2bh
A = 1/2(6 + 2h)(h)
A = h^2 + 3h
If the area of the triangle is 108 square feet, then
A = h^2 + 3h
108 = h^2 + 3h
h^2 + 3h - 108 = 0
Getting the roots of the polynomial.
h^2 + 3h - 108 = 0
(h - 9)(h + 12) = 0
h = 9 ; h = -12
Since h must be a positive number, h = 9 feet.
Substitute the value of h in the equation for b.
b = 6 + 2h
b = 6 + 2(9)
b = 6 + 18

Find an equation in the form y = ax²+bx+c for the parabola passing through the points.
(-4,-40), (-3,-13), (-2,4)
the formula for the parabola that passes through the points, y = ax2 + bx + c. The values of a, b, and c are -9, -19,32 respectively.
What exactly does parabola mean?The intersection of a right circular cone with a plane parallel to an element of the cone creates a plane curve, which is equivalent to a point moving so that its distance from a given point equals its distance from a fixed line.
based on the available facts;
Parabola fundamental: y = ax2 + bx + c
We can plug in three locations for (x, y) to get three equations at once.
(-4, -40): 40 = 4a - 2b + c {equation 1}
(-3, -13): -13 = 9a + 3b + c {equation 2}
(-2,4): 4 = a - b + c {equation 3}
Solve this system to find the values of a, b, c
Let's first eliminate variable c:
4a - 2b + c = -40 {equation 1}
a - b + c = 4 {equation 3}
--------------------- subtract
3a - b = -44
9a + 3b + c = -13 {equation 2}
a - b + c = 4 {equation 3}
-------------------- subtract
8a + 4b = -17
We now have two equations with 2 unknowns we can use to find a, b
3a - b = -44 {equation 4}
8a + 4b = -4 {equation 5}
Multiply equation 4 through by 4 and add equations
12a - 4b = -176
8a + 4b = -4
----------------- add
20a = -180
a = 180/20
a = -9
8a + 4b = -4
4b = -76
b = -19
Plug these 2 values into one of the original equations and solve for c
4 = a - b + c {equation 3}
4 = -9-19 + c
4 = -28 + c
4+28= c
c = 32

The factor is the solution of zeros of the equation and x + 2 making it zero therefore x + 2 will be the solution of the given polynomial so option (B) will be correct.
What are the roots of an equation?Roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.
Given the polynomial,
x³ + 2x² - 9x - 18
A factor is consist of a solution of zeros of any polynomial.
For example;
x² + 5x + 6 = 0
x(x + 2) + 3(x + 2) = 0
(x + 3)(x + 2) = 0
Here x + 3 and x + 2 are factor and solution is x = -3 and -2
Similarly,
x³ + 2x² - 9x - 18 = 0
The factor must be the solution to this.
By cross-checking option
Option (A) x + 1 = 0 → x = -1
Keeping x = -1
(-1)³ + 2(-1)² - 9(-1) - 18 = -8 ≠ 0 so it is not the factor.
Option (B) (x + 2) = 0 → x = -2
(-2)³ + 2(-2)² - 9(-2) - 18
-8 + 8 + 18 - 18 = 0 = 0 so it will be factor of the polynomial.
Hence " x + 2 will be the solution of the given polynomial".
