8. A spinner is divided into 6 equal sections o

Lyrx [107]

Answer:

1/3

Step-by-step explanation:

The numbers are 1, 2, 3, 4, 5, and 6.

Both 3 and 6 are multiples of 3.

So, 2/6 is the probability since there is an equal change that the arrow will land on each section.

This simplifies to 1/3.

Prove the formula for (d/dx)(cos−1(x)) by the same method as for (d/dx)(sin−1(x)). Let y = cos−1(x). Then cos(y) = and 0 ≤ y ≤ π

gtnhenbr [62]

Answer:

$\frac{d(cos^{-1}x )}{dx} = \frac{-1}{\sqrt{1-x^2} }$

Step-by-step explanation:

Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;

let;

$y = cos^{-1} x \\\\taking \ cos\ of\ both\ sides\\\\cosy = cos(cos^{-1} x)\\\\cosy = x\\\\x = cosy\\\\\frac{dx}{dy} = -siny\\$

$\frac{dy}{dx} = \frac{-1}{sin y} \\\\from\ trigonometry\ identity,\ sin^{2} x+cos^{2}x = 1\\sinx = \sqrt{1-cos^{2} x}$

Therefore;

$\frac{dy}{dx} = \frac{-1}{\sqrt{1-cos^{2}y } }$

Since x = cos y from the above substitute;

$\frac{dy}{dx} = \frac{-1}{\sqrt{1-x^{2}} }$

Hence, $\frac{d(cos^{-1}x )}{dx} = \frac{-1}{\sqrt{1-x^2} }$ gives the required proof

17-5(2×-9)=-(-6×+10)+4 Please help me with this problem

uranmaximum [27]

Answer:

x = 17/4 = 4.25

Step-by-step explanation:

We assume your multiplication symbol (×) is intended to be a variable (x).

Simplifying, we have ...

17 -10x +45 = 6x -10 +4

68 = 16x

68/16 = x = 17/4 = 4.25

Check

17 -5(2(4.25) -9) = -(-6(4.25) +10) +4

17 -5(8.50 -9) = -(-25.5 +10) +4

17 -5(-0.5) = 15.5 +4

17 +2.5 = 19.5 . . . . . . true
