Given that cos(theta) = 8/17 and that theta lies in Quadrant IV, what is the exact value of sin 2(theta)?
Answers
Answer: [tex]-\frac{240}{289}[/tex]
=========================================================
Explanation:
Use the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] and plug in the fact that [tex]\cos(\theta) = \frac{8}{17}\\\\[/tex]
Isolating sine leads to [tex]\sin(\theta) = -\frac{15}{17}\\\\[/tex]. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
[tex]\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\[/tex]

Determining the area of a trapezium?The trapezium is a 2 -dimensional plane shape with the area calculated as shown below:
The formula for calculating the area of a trapezoid is expressed as:
Area = 0.5(a + b)h
Given the following parameters
a = 500 ftb = 900ft
height h = 800ft
Substitute the given parameters
Area = 1/2 (500 + 900) * 800
Area = 1/2 (1400) * 800
Area = 560000 square feet
Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:
Total acre = 560000/43560
Total acre = 12.856 acres
Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

The function that describes the area of the rectangle in terms of one of the sides is A = 12L - L².
How to compute the area?The perimeter of the rectangle is given as 24. Therefore, the area in terms of one of its side will be:
A = L(24 - 2L)/2
A = L(12 - L)
A = 12L - L²

how do i solve this?
Answers
There’s a few ways to approach this. You just need to figure out which equations are on that graph. I’d start by identifying the equations for the lines. Remember y=mx+b where mx is the slope and b is the y-intercept. Let’s start with the y-intercepts. They’re labeled for you. One is (0,4) and the other is (0,-4). So we have y=mx+4 and y=mx-4. Next, we need to find the slope. You can count the boxes to do that. Find a neat spot where the line crosses a corner (the y-intercept is often a good place to start) and make a sort of triangle using the line as one side. Count the boxes it takes to get up and over to the next intersection at a corner. The line that crosses at (0,4) goes up (rise) one and over (run) one equally. Rise over run, 1/1x. That can be simplified to just x. So one line is y=x+4. The other line goes down two for every one box it goes over. Remember that when it goes down, it’s negative. So that’s -2/1x, or just -2x. The equation is y=-2x-4. Both of those answers are only present in option J.
PQR is a right angled triangle. The area of the triangle is 6cm² and |QR|= 3cm.
find |PR|
Answers
Answer:
PQ = 4cm
QR = 3cm
PR = 5cm
Area = 6cm²
Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
6 = 0.5 × 3 × PQ
Let PQ be = x6 = 0.5 × 3 × x
[tex] \frac{6}{0.5 \times 3} = x[/tex]
x = 4cm
PQ = 4cm
Since, it is a right angled triangle applying Pythagoras Theorem,
PR =
[tex] \sqrt{ {3}^{2} + {4}^{2} } \\ = \sqrt{9 + 6} \\ = 5cm[/tex]
PR = 5cm
