Answer:

Bottom left graph.

Step-by-step explanation:

Please consider the attached graph for complete question.

We are asked to choose the graph that represents function f(x)=4\cdot 5^x.

We can see that our given function is an increasing exponential function as base of the exponent is greater than 1 and leading coefficient is positive.

Now, we will find the y-intercept to check where the graph intersects y-axis.

To find y-intercept, we will substitute x=0 in our given function.

f(0)=4\cdot 5^0=4\cdot 1 = 4

Since the y-intercept is 4, so graph intersects y-axis at y=4.

Therefore, bottom left graph is the correct choice.

WITH PICTURE!!3. What is the value of x in the regular polygon below? (3 points)
monitta

Answer: FIRST OPTION.

Step-by-step explanation:

Regular polygons are those polygons whose sides are equal in length and whose angles are all equal.

By definition each interior angle of a Regular polygon,is:

\frac{180 ( n -2 )}{n}  (In degrees)

Where "n" is the number of sides of the polygon.

Observe the Regular polygon given in the exercise.

Since it has 6 sides, you can conclude that it is an Hexagon. Then:

n=6

Substituting into  \frac{180 ( n -2 )}{n}  and evaluating, you get:

\frac{180 ( 6 -2 )}{6}=120\°

Knowing this, you can write the following equation:

3x=120

Finally, you must solve for "x" in order to find its value. This is:

x=\frac{120}{3}\\\\x=40

Determine the number of possible triangles, ABC, that can be formed given A = 30°, a = 4, and b = 10.
sweet [91]

Answer:

None

Step-by-step explanation:

We are given a triangle ABC with ∠A = 30°, sides a = 4 and b = 10.

According to the 'Law of Sines- Ambiguous Case', we have,

If a < b×sinA, then no triangle is possible.

If a = b×sinA, only one triangle is possible

If a > b×sinA, two triangles are possible.

So, we have,

b×sinA = 10 × sin30 = 10 × 0.5 = 5.

Now, as

4 = a < bsinA = 5.

We get, according to the rule, no triangle is possible.
