Because the two triangles are similar, one is a scaled down version of the other.

You can figure out that scale by comparing two matching sides, in this case AD and AB.

AD = 2 and AB = 2+4 = 6

So 2/6 = 1/3, telling us each side of the smaller triangle is 1/3 the size of the original.

Now we need to find ED and know CB = 12. Knowing ED = 1/3 of CB:
ED = 1/3 • 12 = 4

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. You notice the rainbow is the shape of a parab
Gekata [30.6K]

We can answer the first part of the question not taking intersecting function into account. The domain of y=-x^{2}+36 is all the numbers, x∈(-∞, +∞) and the range is y∈(-∞, 36]. We can observe these results with the help of a graph, as well. Since we are talking about the rainbow, the values above the ground level will make sense. In this case, we will take into account the range as it changes between 0 and 36, included and the domain between -6 and 6. Here (0;36) is the y-intercept and (-6;0) and (6;0) are the x-intercepts of the parabola.


Since in our problem, the linear function that intersects parabola is not given, we have to provide it by ourselves according to the conditions of the problem. It could be any line intersecting parabola in two points. One important point is that the y-intercept has to be no more than 36. Considering these conditions, we can set our linear function to be y=0.5x+5. We can observe the points that we included in the table (they have been given with orange dots in the graph and the table is attached below). We can see that the values of the function (values of y) are positive. Indeed, we are discussing the part of the rainbow above the ground level.


The system of equations with linear and quadratic functions has got two solutions and we can observe that result from the graph. The solutions are (-5.823; 2.088) and (5.323; 7.662). The solutions are the intersection points.

Answer:

3240°

Step-by-step explanation:

For a regular icosagon,

sum of interior angles measure=180(n-2)°

180(20-2)

Which of the following is equivalent to the inequality shown below?
VARVARA [1.3K]

Answer:

4x + 0.9 \geq 0.1 is equivalent to the inequality 40x+9 \geq 1

Step-by-step explanation:

Given inequality : 4x + 0.9 \geq 0.1

We are supposed to find Which of the following is equivalent to the inequality

4x + 0.9 \geq 0.1

\Rightarrow 4x+\frac{9}{10} \geq \frac{1}{10}

Multiply both sides by 10

\Rightarrow 4(10)x+\frac{9}{10}(10) \geq \frac{1}{10}(10)

\Rightarrow 40x+9 \geq 1

4x + 0.9 \geq 0.1 is equivalent to the inequality 40x+9 \geq 1

So, Option B is true

B) 40x+9 \geq 1
