Step-by-step explanation:
I'll tell you how to do it, but I can't do it for you, sorry. I can't mark the graph.
You make an x and y chart and under x, you write 2,1,0,-1,-2.
You plug it into the equation to get what y equals. Then, you use them as coordinates and plug it into the graph. When you graph all of them, you should see some sort of a 'U' shape. And then you connect the dots on the graph using lines.
Counting numbers from 101 to 200, those with 6 as a digit are 19
<h3>The numbers</h3>
Let's start by listing all the number between 101 and 200
101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200
Now, let's count the numbers with 6 as a digit
= 19 numbers has 6 as a digit
Thus, counting numbers from 101 to 200, those with 6 as a digit are 19

To find it you have to line them up for an example
2;2,4,6,8
4;4,8
And there you see a common number and its 4 and 8 if you wanted least then you would take the 4

Hello,
Step-by-step explanation:
we must first remember that:
![\boxed{sin(5x)=5sin(x)-20*sin^3(x)+16*sin^5(x)}\\\\](https://tex.z-dn.net/?f=%5Cboxed%7Bsin%285x%29%3D5sin%28x%29-20%2Asin%5E3%28x%29%2B16%2Asin%5E5%28x%29%7D%5C%5C%5C%5C)
