<u>Answer:</u>

The problem "You bring $40 to the carnival. You need to keep at least $5 for the bus ride home. How many $3 rides can you go on?" can be solved using the given inequality.

<u>Solution: </u>

The given inequality is 40-3 x \geq 5

For the best solution of the inequality, we need to subtract 40 from both the side of the equation for getting the value of x.  

Now subtracting 40 from both side we get,

40-3 x-40 \geq 5-40

\Rightarrow-3 x \geq 5-40

\Rightarrow-3 x \geq-35

\Rightarrow x=\frac{35}{3}

Now if we put the value of x in the equation, we get,  

\Rightarrow 40-3 \times\left(\frac{35}{3}\right) \geq 5

\Rightarrow 40-35 \geq 5

\Rightarrow 5>=5

The value of x=\frac{35}{3}=11\left(\frac{2}{3}\right)

The answer for the problem will be maximum of 11 rides can be taken.

Distance formula is like pythagoren ahtoerem
D=\sqrt{(7-2)^{2}+(5-8)^{2}}
the distance between oints (x1,y1) and (x2,y2) is
D=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}
(2,8) and (7,5)
D=\sqrt{(7-2)^{2}+(5-8)^{2}}

Answer:

See Explanation Below

Step-by-step explanation:

Given

(sin x - cos x)^2 = sec^2x - tan^2x - 2sinx.cos x.

Required

Prove

To start with; we open the bracket on the left hand side

(sin x - cos x)^2 = (sin x - cos x)(sin x - cos x)

(sin x - cos x)^2 = (sin x )(sin x - cos x)- (cos x)(sin x - cos x)

(sin x - cos x)^2 = sin^2 x -sinx cos x - sin xcos x + cos^2 x

(sin x - cos x)^2 = sin^2 x -2sinx cos x + cos^2 x

Reorder

(sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x

From trigonometry;

sin^2x + cos^2x = 1

So;

(sin x - cos x)^2 = sin^2 x + cos^2 x - 2sinx cos x

becomes

(sin x - cos x)^2 = 1 - 2sinx cos x

Also from trigonometry;

sec^2x - tan^2x = 1

So,  

(sin x - cos x)^2 = 1 - 2sinx cos x

becomes

(sin x - cos x)^2 = sec^2x - tan^2x  - 2sinx cos x

Colin found 22 more mushrooms than Sophie did while they were out picking them in the forest. On the way home, Sophie asked Coli
Vinvika [58]

Answer:

11 mushrooms

Step-by-step explanation:

If Colin has 22 more mushrooms than Sophie, then Sofie has 22 less. Half of 22 is 11, so Colin should have 11 less, and Sophie should have 11 more. If you plug a random value into Sophie's mushrooms, this should still work. For example, if Sophie has 2 mushrooms and Colin has 24, they'll both have 13.

That's not true. 56 is 10 more than 46. 46 +10 is 56.
