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

A faucet is leaking at a rate of 4.2 milliliter per minute. How many gallons of water does the faucet leak per day? Use 1 L = 0.

pentagon [3]

Answer:

1.57 gallons of water to the nearest hundredth.

Step-by-step explanation:

The number of minutes in a day = 24*60 minutes.

1 L = 0.26 gal

So 4.2 milliliters = 0.26 * 4.2 / 1000 gals.

So the number of gallons leaked in a day

= 24* 60 * (0.26*4.2) / 1000

= 1.572 gals.

If we changed the –0.14 to a 2 in the equation, what would happen to the graph?

MatroZZZ [7]

If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope

The equation of the graph is given as:

$y = -0.14x + 3$

The above equation is a linear equation, which is represented as:

$y =mx + c$

Where m represents the slope of the linear equation.

By comparison, we have:

$m = -0.14$

i.e. the slope of the equation $y = -0.14x + 3$ is -0.14

When -0.14 is replaced with 2, the equation becomes

$y = 2x + 3$

And the slope of the new equation $y = 2x + 3$ is

$m =2$

2 is greater than -0.14, and 2 is positive.

This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope
