To the nearest degree, what is m_A? Explain

noname [10]

Answer:

$A= 53$

Step-by-step explanation:

Given

$BC = 9,6$

$AC = 7.2$

Required: Angle A

This is calculated using:

$tan\ A = \frac{Opposite}{Hypotenuse}$

From the attachment;

$Opposite = 9.6$

$Adjacent = 7.2$

So:

$tan A =\frac{9.6}{7.2}$

$tan A =1.333$

Take arctan of both sides

$A= tan^{-1}(1.333$

$A= 53$ ----- approximated

The graphs below have the same shape. what is the equation o the red graph?

maw [93]

So the equation of the red graph is already given to us: $f(x) = x^2$ . I assume you meant the blue graph?

We can use the vertex form: $y = a(x - h)^2+ k$ , where $(h,k)$ is the vertex. (We can ignore $a$ because $a$ is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).
