55% discount rate of $9.

The original price is $9. The discounted price $4. The discount is $5

9-4 = 5
5/9 = 0.55 * 100 % = 55% discount rate of $9.

4/9 = 0.45 * 100% = 45% of the original price is the discount price.

Let
a---------> length of one of the two congruent sides of the triangle

we know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)
so
(a+a) > 8
2a > 8
a> 4
Rounded to the nearest tenth, <span>the smallest possible length of a is 4.1

Dovator [93]

Answer:

The equation is;

y = -1/4x + 607.5

Step-by-step explanation:

Let us have the number of drops as y axis while the number of minutes is x axis

The points to use are;

(30,600) and (130,575)

The slope can be calculated using;

m = (y2-y1)/(x2-x1)

= (575-600)/(130-30) = -25/100 = -1/4

So the equation as we model using the normal equation of a straight line (y = mx + c, m is slope and c is the intercept)

y = -1/4x + c

To get c, we simply substitute one point

Let us use (30,600)

We have

600 = -1/4(30) + c

600 + 7.5 = c

c = 607.5

So the equation is ;

y = -1/4x + 607.5

Sec^2 theta/tan theta = sec theta x csc theta

Andreas93 [3]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tan x = $\frac{sinx}{cosx}$

• sec x = $\frac{1}{cosx}$ , csc x = $\frac{1}{sinx}$

Consider the left side with x = Θ

$\frac{sec^2x}{tanx}$

= $\frac{1/cos^2x}{\frac{sinx}{cosx} }$

= $\frac{1}{cos^2x}$ × $\frac{cosx}{sinx}$

= $\frac{1}{cosxsinx}$

= $\frac{1}{cosx}$ × $\frac{1}{sinx}$

= secxcscx = right side ⇒ verified
