Answer:
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
let : y = Opponent side, x= Adjecent side
and r= hypotenuse
tan = 4/5
y/x = 4/5 => y =4, x=5
so, r = √4²+5²=√16+25=√41
sin = y/r = 4/ √41
cos = x/r = 5/√41
tan = y/x = 4/5
csc = r/y = √41 /4
sec = r/x = √41 /5
cot = x/y = 5/4
12. You divide 30 by 5 to get 4. Then multiply 4 by 3 to get 12. You need 12 oz of red. Hope this helps!
Answer:
<h3>
x-intercepts: (-7, 0) and (7, 0)</h3><h3>
y-intercept: (0, -49)</h3>
Step-by-step explanation:
x-intercepts: f(x) = 0
x² - 49 = 0
x² = 49
x = -7 ∨ x = 7
Points: (-7, 0) and (7, 0)
y-intecept: y = f(0)
f(0) = 0² - 49 = -49
Point: (0, -49)
