Answer:
$21,389.79
Step-by-step explanation:
Let x be the attendance in the fourth show to reach the
average they want.
So to solve:
100 + 105 + 91 + x
----------------------- > 100
4
296 + x
--------------- >
100
4
Then, multiply both sides by 4 and the result is:
296 + x > 400
X > 400 – 296
X > 104 is the number to achieve the desired attendance
average
Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
Instructions? Pls don't make your helpers guess.
First problem: f(x) = -(x+4)^2 + 1
a) First, graph g(x) = x^2 (a parabola). Then reflect your graph in the x-axis, because of the "-" sign. This will give you the graph of h(x) = -x^2.
b) Now move the entire graph 4 units to the LEFT. This will give you the graph of j(x) = -(x+4)^2.
c) Now move the entire graph of j(x) UP by one unit.
This will give you the desired graph, of f(x).
