2. Abby found the axis of symmetry, x-coordinate, the vertex, and y-intercept

krek1111 [17]

Using quadratic function concepts, it is found that Abby made a mistake on the coordinates of the vertex, which are (-4,1).

----------------------

A quadratic function is defined by:

$y(x) = ax^2 + bx + c$

The y-intercept is given by point: $(0, y(0))$
The vertex is given by: $(-\frac{b}{2a}, y(-\frac{b}{2a}))$ .
The axis of symmetry is: $x = -\frac{b}{2a}$

----------------------

The function given is:

$f(x) = -x^2 - 8x - 15$

Which is a quadratic equation with: $a = -1, b = -8, c = -15$ .
$f(0) = -0^2 - 8(0) - 15 = -15$ , thus, the y-intercept is (0, -15).

$x_v = -\frac{b}{2a} = -\frac{(-8)}{2(-1)} = \frac{8}{-2} = -4$

Thus, the <u>x-coordinate of the vertex</u> is x = -4, which is the same as the <u>axis of symmetry</u>.

$f(-4) = -(-4)^2 - 8(-4) - 15 = 1$

The vertex is given by: (-4,1).

How do you rewrite 6/9 in two different ways

Naya [18.7K]

We have to represent the fraction $\frac{6}{9}$ in two different ways.

Let us multiply the numerator and denominator of the given fraction by '2'.

Therefore, $\frac{6}{9} = \frac{6 \times 2}{9 \times 2} = \frac{12}{18}$

Therefore, $\frac{12}{18}$ is the first way to represent the given fraction.

Now, Let us multiply the numerator and denominator of the given fraction by '3'.

Therefore, $\frac{6}{9} = \frac{6 \times 3}{9 \times 3} = \frac{18}{27}$

Therefore, $\frac{18}{27}$ is the second way to represent the given fraction.

Therefore, $\frac{12}{18}$ and $\frac{18}{27}$ are the different ways to represent the fraction $\frac{6}{9}$ .

1+sin(a)/1+csc(a)=tan(a)/sec(a)

strojnjashka [21]

Answer:

Below.

Step-by-step explanation:

( 1 + sin a) / (1 + csc a)

= (1 + sin a ) /( 1 + 1/ sin a)

= ( 1 + sin a) / (sin a + 1)/ (sin a)

= (sin a(1 + sin a)) / (1 + sin a)

= sin a.

tan a / sec a

= (sin a / cos a) / (1 /cos a)

= (sin a cos a) / cos a

= sin a

The two expressions are both equal to sin a:

Therefore

(1 + sin a) /( 1 + csc a) = tan a / sec a.
