in the form ax²+bx+c, in which a, b, and c are constants, the value of given quadratic equation a+b+c is 0.

Simplification is the process of making an expression or equation simpler, while still maintaining its meaning or function. This can be done by combining like terms, combining or removing unnecessary elements, or applying mathematical rules or identities.

For example, in algebra, simplifying an expression might involve combining the coefficients of similar terms (such as 2x + 3x = 5x), or factoring out a common factor from multiple terms (such as [tex]2x^2 + 4x = 2x(x+2).[/tex]

The goal of simplification is to make the expression or equation easier to understand, manipulate, or solve.

The expression given is already in the form ax^(2) + bx + c, so we can simply add the coefficients of the x^(2), x and constant terms to find the value of a+b+c:

[tex](2x^{(2)} -3x+1)-(-2x^{(2)}-3x+2) = 2x^{(2)} - (-2x^{(2)}) + (-3x) - (-3x) + 1 - 2[/tex]

a+b+c = 2 - (-2) + (-3) - (-3) + 1 - 2 = 2 + 2 - 3 - 3 + 1 - 2 = 0

Therefore, the value of a+b+c is 0.

2 3 as an exponent is written as 2^3 and it represents 2 multiplied by itself 3 times. 2^3 = 2 * 2 * 2 = 8

In the notation 2^3, the number 2 is the base and the number 3 is the exponent. The exponent tells you how many times the base is being multiplied by itself. In this case, 2 is multiplied by itself 3 times.

It's important to note that the exponent is also known as the power, so 2^3 is also read as 2 to the power of 3.

In summary, 2 3 as an exponent is written as 2^3 and it represents 2 multiplied by itself 3 times, or 2 to the power of 3 which is equal to 8. Understanding this concept is important for solving mathematical problems, especially in algebra and calculus.

Answer:

y = 2x + 5

Figure 505

Step-by-step explanation:

Find the slope

Change in y over the change in x

[tex]\frac{13-11}{4-3}[/tex] = [tex]\frac{2}{1}[/tex] = 2

slope (m) is 2.

Part A

Find the y -intercept

m = 2

x = 3     from the point (3,11)

y = 11    from the point (3,11)

y = mx + b  Substitute what I know and solve for b

11 = (2)(3) + b

11 = 6 + b  Subtract 6 from both sides

11 - 6 = 6 -6 + b

5 = b

The y intercept (b) is 5

y = mx + b

y = 2x + 5

Part B

y =  2x + 5

1015 = 2x + 5  Subtract 5 from both sides

1015 - 5 = 2x + 5 - 5                                                    

1010 = 2x  Divide both sides by 2

The balance on the credit card after three years would be $20,111.25.

What is continuous compound interest?

Continuous compounding means that there is no limit to how often interest can compound. Compounding continuously can occur an infinite number of times, meaning a balance is earning interest at all times.

The balance on the credit card after three years can be calculated using the formula for continuous compound interest:

A = P * e^(rt)

where A is the final balance, P is the initial principle (the amount of the loan), r is the annual interest rate as a decimal, and t is the number of years.

In this case, P = $12,500, r = 0.1599 (15.99% as a decimal), and t = 3.

Plugging these values into the formula:

A = $12,500 * e^(0.1599 * 3)

A = $12,500 * e^0.4797

A = $12,500 * 1.6089

A = $20,111.25

Rounded to the nearest penny: $20,111.25

Hence, the balance on the credit card after three years would be $20,111.25.

Step-by-step explanation:

Area of white triangle:

             base = 9 cm

           height = 14 cm

       [tex]\sf \boxed{Area \ of \ triangle = \dfrac{1}{2}*base *height}[/tex]

                                    [tex]\sf =\dfrac{1}{2}*9*14\\\\ = 9*7\\\\= 63 \ cm^2\\[/tex]

Area of trapezium:

          [tex]\sf \boxed{Area \ of \ trapezium =\dfrac{(a+b)*h}{2}}[/tex]

Here, a and b are the parallel sides of trapezium & h is the height.

           a = 9 cm ; b = 17 cm and h =14 cm

[tex]\sf Area \ of \ trapezium = \dfrac{(9+17)*14}{2}[/tex]

                           [tex]= \dfrac{26*14}{2}\\\\\\=13*14\\\\= 182 \ cm^2[/tex]

Area of shaded region = area of trapezium - area of white triangle

                                      = 182 - 63

                                      = 119 cm²

Answer:

area of shaded region = 119 cm²

Step-by-step explanation:

the outer figure has one pair of parallel sides and is a trapezium.

the shaded area (A) is calculated as

A = area of trapezium - area of white triangle

the area of a trapezium is calculated as

area = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between the bases b₁ and b₂

here h = 14 , b₁ = 9 , b₂ = 17 , then

area = [tex]\frac{1}{2}[/tex] × 14 × (9 + 17) = 7 × 26 = 182 cm²

the area of the triangle is calculated as

area = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

here b = 9 and h = 14 , then

area = [tex]\frac{1}{2}[/tex] × 9 × 14 = 4.5 × 14 = 63 cm²

then area of shaded region (A) is

A = 182 - 63 = 119 cm²

It is "3 pairs" not "3 pair", because a pair is a set of two things, so if you have 3 of them it would be 3 sets of two things or 3 pairs.

In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:

P = 2*(6in + 14in)

P = 2*20in = 40in

The equation in slope intercept form is

y = 5/2x + 5

One of the most popular ways to describe a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula may be used to get the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.

The slope intercept form is a technique for figuring out a straight line's equation in the coordinate plane. Any point's coordinates on a straight line must fulfill a certain relation, which is known as the equation of a straight line.

Any location that is not on the line will not fulfill the coordinates.

This equation's solution is simple to find. A straight line's slope, or angle of inclination from the x-axis, and the intercept it makes with the y-axis are both necessary to determine the slope intercept form of the line.

Two points on the line are (-2,0) and (0,5)

The slope intercept form is

y = mx + c

so when y = 0 and x = -2

0 = -2(m) + c

or,  2m -c = 0 ..(i)

again when x= 0 y = 5

5 = 0*m + c

c = 5

so putting c= 5 in equation (i) we get

m = 5/2

so the equation in slope intercept form is

y = 5/2x + 5

The rate of change for a linear function, also known as the slope, can be found by calculating the change in the y-coordinate (rise) divided by the change in the x-coordinate (run) between two points on the line. The slope of a line describes how steep the line is and whether it is increasing or decreasing.

In this case, the slope of the linear function can be found by using the coordinates of points E and F:

Slope = (y2 - y1) / (x2 - x1)

Slope = (-8 - 27) / (5 - 0)

Slope = -35/5

The slope of the linear function is -35/5 or -7.

The initial value of a linear function is the y-intercept, which is the point where the line crosses the y-axis. To find the y-intercept, we can use the slope and one point on the line (in this case point E (0,27)):

y = mx + b

27 = -7(0) + b

b = 27

The y-intercept of the linear function is 27.

So, the linear function starts at point E (0,27) with an initial value of 27, and has a rate of change or slope of -7.
