How do you solve this pls
solong [7]

Step-by-step explanation:

The equation of a exponential function is

a \times (b) {}^{x}

where a is the y value of the y intercept, b is the constant rate of change.

Here the y intercept is (0,4), the y value of the y intercept is 4.

So a=4

The graph passes through point (1,2) so

h(x) = 4 \times b {}^{x}

Plug in 1 for x, 2 for h(x)

2 = 4 \times  {b}^{1}

Anything to the first power is itself so

2 = 4 \times b

Isolate b.

\frac{1}{2}  = b

So our function is

4 \times ( \frac{1}{2} ) {}^{x}

A right rectangular prism's edge lengths are 12 inches, 2 1/6 inches, and 4 inches. How many unit cubes with edge lengths of 2/3
zhenek [66]

Answer:

<h2>324 cubes</h2>

Step-by-step explanation:

We calculate how many cubes will fit along each edge:

12 in : 2/3 in = 12 · 3/2 = 18 cubes

2 1/6 in : 2/3 in = 13/6 · 3/2 = 39/12 = 13/4 = 3 1/4 → 3 cubes

4 in : 2/3 in = 4 · 3/2 = 6 cubes

(18)(3)(6) = 324

Given:

The figure of triangle LNM.

To find:

The Law of Sines for the given triangle.

Solution:

Law of sines: In triangle ABC,

\dfrac{\sin A^\circ}{a}=\dfrac{\sin B^\circ}{b}=\dfrac{\sin C^\circ}{c}

Similarly, the Law of Sines for the given triangle LNM is:

\dfrac{\sin L^\circ}{l}=\dfrac{\sin N^\circ}{n}=\dfrac{\sin M^\circ}{m}

Therefore, the correct option is b.
