The density of an isosceles right triangle (side lengths 1,1,√2) is the square ofthe distance to one of the 45◦vertices.(a) find its center of mass (choose an appropriate coordinate system and make a ) find its moment of inertia if the point of rotation is the vertex with the right angle.
Explanation: A formal tone is required in a presentation, and you are telling them you want new computers, so you would want to persuade them into getting new computers!
An ECG is appropriate to determine if her heart is working properly. Problems with her heart or her arterial pressure could have caused the loss of her visual field and that red spot in her eye. As she stated that she feels nervous and has lost weight, she may have hyperthyroidism, which is making her feel that way and has damaged her eye. The first step to check if hyperthyroidism has caused atrial fibrillation is an ECG.
The answer is A. He is trying to persuade the school board to purchase some new computers for the media center. He needs to speak in a formal tone to successfully persuade his audience.
Each center is the point ofof the appropriate lines in a triangle
point of contact
The correct answer is A. A formal tone, because his purpose is to persuade his audience
The tone used in a speech or presentation depends on many factors that include the type of audience, the purpose of the presentation, the topic addressed, among others. In the case of Mason because he is going to deliver a presentation for the school board the needs to use a formal tone, considering this is an academic or formal context. Also, the tone should be formal because he is not only sharing ideas with the school board but he aims at persuading them about the need of new computers, which means his presentation needs to include arguments and evidence organize logically and using formal language. Therefore, the more appropriate tone is "a formal tone, because his purpose is to persuade his audience".
The Lewis structure is shown below.
In the molecule given, the central atom is the carbon (C), which must do 4 bonds. The other carbons at the molecule must do 4 bonds too, and the hydrogens must do only one bond. So, the central atom does a double bond with each carbon, and each carbon does a single bond with the two hydrogens they're bonded.
After the bonds, the central carbon has no lone pairs of electrons, so the geometry of the molecule must be linear, as shown below.
Mason is attempting to persuade the school board to get new computers for the media center.
Hope this helps!
