ELEN [110]2 years ago
6 0

Answer: (4)

Step-by-step explanation:

The first part has a closed hole at x=0 and an open hole at x=4, so it should be 0 \leq x < 4.

This eliminates all the options except for (4).

Explain why the triangles are similar then find out the distance represented by x​
elena55 [62]

Because the only difference between them is size so the basic form of the shape remains, having corresponding sides in proportion.

<h2>Explanation:</h2>

Two triangles are similar if the only difference between them is size. Put another way, the basic form of the shape remains. If this is true, then:

  • Corresponding angles are congruent
  • Corresponding sides are in proportion

Since you didn't provide any graph, I have attached two similar triangles below. As you can see they are right triangles. As we said, corresponding sides of similar triangles are in proportion, so it is true that:

\frac{9}{3}=\frac{12}{4}=\frac{x}{5}=3 \\ \\ \therefore \frac{x}{5}=3 \\ \\ \therefore x=5(3) \\ \\ \therefore \boxed{x=15}

A circle has a circumference of 28.2628.2628, point, 26 units. What is the diameter of the circle?
saul85 [17]

Answer:

8.28 units

Step-by-step explanation:

The formula for the circumference of a circle is C=\pi d

where

C is the circumference of the circle

d is the diameter of the circle

We know form our problem that the circumference of our circle is 26.28 units, so C=28.26. Let's replace that value in our formula and find d:

C=\pi d

26=\pi d

Divide both sides of the equation by \pi

\frac{26}{\pi } =\frac{\pi d }{\pi }

\frac{26}{\pi } =d

d=\frac{26}{\pi }

d=8.28

The diameter of the circle that has a circumference of 28.26 units is 8.28 units.
