Answer:

See Explanation

Step-by-step explanation:

Given

\triangle ABC = \triangle DE F

Required

Which would not prove the similarity

\triangle ABC = \triangle DE F  implies that:

The following angles are congruent

\angle A = \angle D

\angle B =\angle E

\angle C =\angle F

And the following lengths are congruent

AB = DE

BC =EF

CA = FD

The options are not clear; so, it's a bit difficult to select the correct option.

<em>Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.</em>

Jesse made a model of a mountain range for class. to do this, he bought a cylinder of cardboard and cut it into three cones. eac
aniked [119]
By definition, the volume of the cone is given by:
 V = (1/3) (π) (r ^ 2) (h)
 Substituting values we have:
 V = (1/3) (π) ((4/2) ^ 2) (5)
 V = (20/3) (π)
 Then, the volume of the cylinder is:
 Vc = 3 * V
 Vc = 3 * (20/3) (π)
 Vc = 20π
 Answer:
 
the volume of the original cylinder jesse bought is:
 
Vc = 20π

Please answer for BRAINLIEST!
oee [108]

Answer:

1.5 units squared

Step-by-step explanation:

Area of a Triangle formula: A = 1/2bh

Pythagorean Theorem: a² + b² = c²

Since you are missing the <em>h </em>to find the area of the triangle, you must use Pythagorean to find the 3rd missing side (it is a right triangle so you can use Pythagorean).

Step 1: Use Pythagorean

2.5² = 1.5² + b²

4 = b²

b = 2

Step 2: Switch variables

b (from Pythagorean) = h (height for Area)

Step 3: Solve for Area

A = 1/2(1.5)(2)

A = 1.5

And you have your final answer.

The function below models the voltage, in volts, of a certain alternating current after x seconds, where A and b are positive co
Katarina [22]

First of all, we can just ignore A, it has no effect but to vertically stretch our cosine.

If it was only f(x)=cosx, the function would be invertible as long as it's confined between 0 and \pi. Now, the argument of our cosine is not x but bx. It means that it won't stop at \pi, but at \frac{\pi}{b}.

Another way to think about it, "what should i replace x with so I get \pi inside the cosine?"
