It is best to use graph paper to visualise. A(-7, 9) is in 2nd quadrant, rotating 90 CCW brings the point in the 3rd quadrant to (-9, -7)

in general P (a, b) CCW P’(-b,a)

Simplify the expression ?
melomori [17]

Answer:

The answer is cscx(cscx - 1) ⇒ the second answer

Step-by-step explanation:

∵ csc²x = cot²x + 1

∴ \frac{cot^{2}x+1-1 }{1+sinx}=\frac{cot^{2}x }{1+sinx}

Multiply the fraction by its conjugate 1 - sinx (up and down)

∴ \frac{cot^{2}x }{1+sinx}*\frac{1-sinx}{1-sinx}=\frac{cot^{2}x(1-sinx) }{1-sin^{2}x}

∵ 1 - sin²x = cox²x

∴ \frac{cot^{2}x(1-sinx) }{cos^{2}x }

∵ cot²x = cos²x/sin²x

∴ \frac{1-sinx}{sin^{x}}=\frac{1}{sin^{2}x}-\frac{sinx}{sin^{2}x}=csc^{2}x-cscx

Take cscx as a common factor

∴ cscx(cscx - 1)

Normal probability Density Function Use a graphing utility to graph the model probability density function with µ = 0 and ð = 2,
Nuetrik [128]

Answer:

Step-by-step explanation:

Hello!

The standard deviation (δ) is a measure of variability, this means, it shows how dispersed the data set is with respect to the mean. The population mean (μ) is a measurement of position. The three graphics have the same position μ=0 but their standard deviations change, this means, the form of their bells is different. The greater the value of the standard deviation, the more dispersed the data is you can see this graphically because the width of the bell will be greater.

Graph attached.

I hope it helps!

Help pls I'm so confused with this

Answer:

6400 AED

9.14%

yes. The interest rate is 9.14%. This is less than 10%

Step-by-step explanation:

Interest amount she would pay = total of loan to be repaid - amount borrowed

16,400 - 10,000 = 6,400 AED

Interest = loan x interest rate x time

we have all the parameters of the above equation apart from the interest rate. We can thus determine the interest rate from the above equation

6,400 AED = 10,000 x interest rate x 7

6,400 AED = 70,000 x interest rate

Divide both sides by 70,000 to find a value for interest rate

interest rate = 0.091429 = 9.14%
