Given the graph which <span>shows the population of a bacteria in an experiment, measured every hour.

The graph is a graph of an exponential function.

An exponential function is given by
f(t) = a(r)^t
where: a is the initial value of the function when t = 0,
r is the growth/decay rate, and
t is the time elapsed.

From the graph, the initial size of the population when t = 0 is 10, thus, the value of a in the function is 10.

Also, from the graph, after 2 hours, the popolation of bacteria was 20,
i.e.
20=10(r)^2 \\  \\ r^2=2 \\  \\ r= \sqrt{2} =1.4

Therefore, the </span><span>function representing the population of the bacteria after t hours is
f(t)=10(1.4)^t
</span>

If ADEF is reflected over the x-axis, what would be the coordinates of point F?
Brut [27]

Answer:

Please check the explanation.

Step-by-step explanation:

Let the coordinates of the point F be (x, y).

When a point F(x, y) is reflected over the x-axis, the x-coordinate of the point F remains the same, and the y-coordinate of the point reverses the sign.

Thus, the rule of reflection over the x-axis:

F(x, y)   →    F'(x, -y)

Here,

F'(x, -y) would be coordinates of point F after the reflection over the x-axis.

Let say, the point F(1, 2).

The coordinate of the point F after the reflection over the x-axis would be:

F(1, 2)   →    F'(1, -2)

Thus, F'(1, -2) would be the coordinates of point F after the reflection over the x-axis.

How do I find the missing sides of this triangle by using trigonometry
Lemur [1.5K]

Step-by-step explanation:

Use SOH-CAH-TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

You're given an angle, the adjacent side to that angle, and the hypotenuse.  So use cosine.

Cosine = Adjacent / Hypotenuse

cos 37° = 48 / x

Multiply both sides by x.

x cos 37° = 48

Divide both sides by cos 37°.

x = 48 / cos 37°

If desired, use a calculator to evaluate.

x ≈ 60.1
