Recall "All Silver Tea Cups"
or All Sin Tan Cos

Quadrant 1 : All trigonometric ratios are positive.
Q2: only sin (and cosec)
Q3 : only Tan (and cot)
Q4 : only Cos (and cosec)

So, cot theta will be negative in Quadrant 2,4
and cos theta will be negative in Quadrant 2,3

In Quadrant 2, both will be negative!

Tammy brought 3 apps for $2.40. At the same price, how much would 10 apps cost​
vitfil [10]

Answer:

The answer is $8.00.

Step-by-step explanation:

First, you have to find how much for each app so you have to divide by 3 :

3 apps = $2.40

1 app = $2.40 ÷ 3

1 app = $0.80

Next, you have to multiply it by 10 :

1 app = $0.80

10 apps = $0.80 × 10

10 apps = $8.00

Solve the equation 58 - 10x ≤ 20 + 9x
drek231 [11]

Answer:

x≥2

Step-by-step explanation:

First, write out the equation as you have it:

58-10x\leq20+9x

Then, add 10x to both sides:

58-10x+10x\leq20+9x+10x\\58\leq20+19x

Next, subtract 20 from both sides:

58-20\leq20-20+19x\\38\leq19x

Finally, divide both sides by 19:

\frac{38}{19}\leq\frac{19x}{19}\\2\leq x

or

x\geq 2

Therefore: the answer to this inequality/equation is: x≥2
