The gap is selling shirts for 30% off the original price. The shirts are on sale for $22.40. What was the original price of the shirt?

Answers

If you would like to know what was the original price of the shirt, you can calculate this using the following steps:

30% + 100% = 130%

130% of $22.40 = 130% * 22.40 = 130/100 * 22.40 = $29.12

The original price of the shirt was $29.12.

The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the graph?

Answers

The coordinates of the vertex of the graph are (-2, -9).

Further explanation

The quadratic function is described by the standard equation \boxed{ \ f(x) = ax^2 + bx + c \ }.  The graph of a quadratic function is called a parabola.

We have the quadratic function \boxed{ \ f(x) = x^2 + 4x - 5 \ }.

  • We identify the coefficients a, b, and c. For this equation, \boxed{ \ a = 1, b = 4, and \ c = -5 \ }
  • The axis of symmetry is \boxed{ \ x = h = -(b)/(2a) \ }, i.e., \boxed{ \ x = h = -(4)/(2(1)) \rightarrow h = -2 \ }. Thus, the statement in the question for the symmetry axis x = -2 is correct.
  • The vertex (or turning point) is \boxed{ \ (h, k) \ }, where \boxed{ \ k = f(h) \ }  or \boxed{ \ k = (b^2 - 4ac)/(-4a) \ }
  • The parabola opens upward because a > 0, resulting in a vertex that is a minimum.

Finding the minimum value is as follows:

  • \boxed{ \ k = f (-2) = (-2)^2 + 4(-2) - 5 \rightarrow k = -9 \ }, or
  • \boxed{ \ k = (4^2 - 4(1)(-5))/(-4(1)) = -(36)/(4) \rightarrow k = -9 \ }

Therefore, the coordinates of the vertex of the graph are (h, k), i.e., \boxed{\boxed{ \ (-2, -9) \ }}

Other components:

  • The y-intercept of the quadratic function f(x) = x² + 4x - 5 is (0, c), i.e., the point \boxed{ \ (0, -5) \ }.
  • The factorization of f (x) = x² + 4x - 5 becomes f(x) = (x + 5)(x - 1). Then we get the x-intercepts at \boxed{ \ (-5, 0) \ and \ (1, 0) \ }

Keywords: the axis of symmetry, for a function, f(x) = x² + 4x − 5, x = −2, which is the graph of f(x) = (x - 1)(x + 4), what, the coordinates of the vertex of the graph, the x-intercept, quadratic function, a standard equation, the y-intercept, parabola, upward, the minimum value

Based on the calculations, the coordinates of the vertex(h, k) of this graph are equal to (-2, -9).

The standard form of a quadratic equation.

In Mathematics, the standard form of a quadratic equation is given by;

ax² + bx + c = 0

Note: The graph of any quadratic function is known as a parabola.

From the given quadratic function, we have:

f(x) = x² + 4x - 5

For its coefficients, we have:

  • a = 1.
  • b = 4.
  • c = -5.

Next, we would determine the coordinates of the vertex of this graph:

x = h = -b/2a

h = -4/2(1)

h = -4/2

h = -2.

Also, we can deduce that the parabola of this graph opens upward because "a" is greater than zero (0), which produces a vertex that is a minimum:

f(h) = k

f(-2) = k = (-2)² + 4(-2) - 5

f(-2) = k = 4 - 8 - 5

k = -9.

Vertex (h, k) = (-2, -9).

In his study of pea plants, Gregor Mendel used which method to produce offspring?a.cross-pollination, by using parents that had identical traits
b.cross-pollination, by using parents that had different traits
c.self-pollination, by using one parent
d.random pollination, by using both identical- and different-trait matings

Answers

In his study of pea plants, Gregor Mendel used Cross-pollination method to produce offspring.Therefore the answer is b.cross-pollination, by using parents that had different traits. The traits of two different organism can be seen in the microscope.

we know that

Gregor Mendal used a process of cross-pollination,by using parents that had different traits in his experiment with pea plants. He was studying the difference between tall and short pea plants, and how genes were expressed differently between the two, so this method of cross-pollination was vital in order to accurately recreate how this process would happen within nature.

therefore

the answer is the option

b.cross-pollination, by using parents that had different traits

The equation for the circle below is x2 + y2 = 100. What is the length of the
circle's radius?

Answers

Answer:

Step-by-step explanation:

x²+y² =(Radius)²

x²+y² =10². So the radius is 10

Answer:

radius = 10

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

x² + y² = 100 ← is in this form

with r² = 100 ( take the square root of both sides )

r = √(100) = 10
