They need to put 14.4 grams of onion powder in each bottle.
Given,
The quantity of onion powder in a seasoning blend = 4%
We have to find the quantity of pure onion powder should they include in a 72g bottle to make the final blend have 20% onion powder;
How much is a percentage?
A percentage is a certain number or part in every hundred. It is a fraction with the denominator 100, and the symbol for it is "%."
Here,
Let x be the seasoning blend.
Now, 4% of 72=20% of x
⇒ 0.04×72=0.2×x
⇒ 0.2x=2.88
⇒ x=2.88/0.2
⇒ x=14.4 g
Therefore, a container should contain 14.4 grams of onion powder.

Step-by-step explanation:
sec⁴B - sec²B = sec²B(sec²B - 1)
= (1 + tan²B)(tan²B)
= tan⁴B + tan²B
= Right-hand side (Proven)
The best way to figure this out is to rewrite the equation in to standard slope form:
y = mx + b
this would look like...
5y = -7x + 35
divide 5 from each side of the equation...
-7
y = —— x + 7
5
find the values you can graph...
b = y intercept = the point in which the line "hits" the y axis on the graph. so count 7 points up and plot a point on the y axis at 7.
once you plot that, this is the starting point of your slope...
-7 (rise) count 7 down
m = slope = —— (over)
5 (run) count 5 to the right

Tan (x + pi/2) = -cot x
<span>tan (pi/6 + pi/2) = -cot (pi/6) </span>
<span>tan (2pi/3) = -cot (pi/6) </span>
<span>-sqrt (3) = -[sqrt 3] <<< so it is true for x = pi/6</span>
