1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation.
2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π).
3. answer: y=5sin2x.
Answer:
Option A- One
Step-by-step explanation:
Given that : The sides of the triangle measuring 6cm, 2cm and 7cm.
We are using : Triangle inequality
The sum of the length of the two sides should be greater than the length of the third side.
So, when we apply this theorem in 6cm,2cm and 7cm
6+2=8>7 , 7+2=9>6 , 7+6=13>2
It satisfy all three possible sets.
Therefore, the given values follows the triangle inequality.
Hence one triangle can be formed.
Therefore, option A is correct.
Correct Answer:
Option C. Camera 2The greatest angle is always opposite to the side measure greater in length. So first we find the greatest side.
The distance between cameras is:
Camera 1 and Camera 2 : 106 feet
Camera 2 and Camera 3 : 133 feet
Camera 1 and Camera 3 : 151 feet
So the largest side of the triangle is the side between camera 1 and camera 3. So the camera opposite to this side will have to cover to greatest angle. The camera opposite to this side is Camera 2. This scenario is also shown in figure below.
Therefore, Camera 2 had to cover the greatest angle.
Answer: There are 7 crayons in each box.
Step-by-step explanation: First, the most difficult part is coming up with the equation. You know that she has a total of 59 since it mentioned “a collection of 59 crayons”. Then you also know there are 17 crayons on the side, so you can subtract 17 from 59, the total (which is now 42). Then you have 6x. 6 is for the number of boxes and x is for the unknown number of crayons found in each box. Then you can just simply solve after identifying each factor of the equation.
