Answer:

the answer of this question is " 1 "

Step-by-step explanation:

tanx = sinx/cosx

cotx = cosx/sinx

cscx = 1/sinx

after putting them all in the given equation

sinx.(sinx/cosx).(cosx/sinx).(1/sinx)

they all are canceled as all are being multiplied with their reciprocals so answer is " 1 "

Anton [14]

Answer:

The correct answer is US$ 444.06

Step-by-step explanation:

1. Let's check all the information that was provided in the question:

Salary per hour earned by Don Moline = US$ 12.25

Number of hours worked last week = 36 1/4

2. For calculating the payment Don will receive, we do the following:

Straight-time payment = Salary per hour earned by Don * Number of hours worked last week

Straight-time payment = 12.25 * 36 1/4

Straight-time payment = 12.25 * 36.25 (1/4 = 0.25)

Straight-time payment = US$ 444.06

Don Moline will receive US$ 444.06 of payment

L1 and L2 are two straight lines. The origin of the coordinate axes is O. L1 has equation 5x + 10y = 8 L2 is perpendicular to L1

Ivenika [448]

Answer:

40 sq units

Step-by-step explanation:

$5x + 10y = 8\\\Rightarrow y=\dfrac{8-5x}{10}\\\Rightarrow y=-\dfrac{1}{2}x+\dfrac{2}{5}$

Slope of $L_2$ is $m_2$

$m_1m_2=-1\\\Rightarrow m_2=-\dfrac{1}{m_1}\\\Rightarrow m_2=-\dfrac{1}{-\dfrac{1}{2}}\\\Rightarrow m_2=2$

$L_2$ passes through point $(8,6)$

$y-6=2(x-8)\\\Rightarrow y=2x-16+6\\\Rightarrow y=2x-10$

Point at x axis where $L_2$ intersects is

$0=2x-10\\\Rightarrow x=\dfrac{10}{2}\\\Rightarrow x=5$

Point $A$ of the triangle will be $(5,0)$

$L_2$ intersects line $x=-3$ . The point is

$y=2\times(-3)-10\\\Rightarrow y=-6-10\\\Rightarrow y=-16$

The points of the triangle are $A(5,0), O(0,0), B(-3,-16)$

Area of triangle is given by

$A=\dfrac{|A_x(B_y-O_y)+B_x(A_y-O_y)+O_x(A_y-B_y)|}{2}\\\Rightarrow A=\dfrac{|5(-16-0)+-3(0-0)+0(0-(-16))|}{2}\\\Rightarrow A=40\ \text{sq units}$

The area of the triangle is 40 sq units.
