True because tan(20)=2.1 and cot(20)=is o.44
Because when we divide that by itslef you get the exact same number
2x^2 + x -3 can be factorised
<span>[2x + 3][x - 1] </span>
<span>As length times width = area </span>
<span>one possible set of measurements are </span>
<span>length = [2x + 3] </span>
<span>width = [x-1] </span>
Answer:
$300
Step-by-step explanation:
Money that she earns per hour:

Step-by-step explanation:
0 = sqrt(x - 4) + 3 Set equation equal to 0
-3 = sqrt(x - 4). Subtract 3 from both sides
the principle square root will only output positive values, since if it every outputted a negative value it would not be a function since a function cannot have 2 outputs for the same input.
no x-intercept
