<u>Answer:</u>

Mitch has taken 17 complete lesson and 60% of one last lesson.  

<u>Solution: </u>

Dan and Laura needs to pay certain amount for swimming lessons.

Dan took four lessons and paid $ 100

Laura took 8 lessons and paid $ 200.

Need to calculate number of lessons taken by Mitch when amount paid by Mitch = $440.

Let’s first calculate price of one lesson.

For 4 lessons of Dan, payment = $100

So for 1 lesson of Dan, payment \frac{100}{4} = 25

For 8 lessons of Laura, payment made = $200

So for 1 lesson of laura, payment made = \frac{200}{8} = 25

So clearly cost of 1 lesson = $ 25.

So <em>number of lessons taken by Mitch</em> = Amount spent / cost of 1 lesson

= \frac{440}{25} = 17.6

So Mitch has taken 17 complete lesson and 60% of one last lesson.

Prove these identities <br>(i) secx cosecx - cotx = tanx<br>​
brilliants [131]

Answer:

(A)\frac 1 {cosx} \frac 1 {sin x}  - \frac {cosx} {sin x} = \frac {sin x} {cosx} \\\\(B)\frac{1-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(C) \frac{(sin^2x + cos^2x)-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(D) \frac{sin^2x }{cos x sin x} = \frac {sin x} {cosx}\\\\(E)\frac {sin x}{cos x} = \frac {sin x}{cos x}

In step A, you replace all trigonometric functions with their definitions in terms of sine and cosine.

In step B, you add the two together as you add fractions.

In step C, you replace 1 with the sum of the squares of sine and cosine.
In step D, you add the cosine terms together so they disappear.

In step E, finally, you divide numerator and denominator by sin x.

Help me please with this geometry

All Triangles are equilateral ( each side = 4)


Area of a Triangle is (B x H)/2. B being the base ( 4) & H the altitude.

WE know that altitude in an equilateral triangle, H = ( side x√3)/2

So H= (4√3)/2 = 2√3

The area of one triangle = (4 x 2√3)/2 = 4√3

And for the 3 triangles the lateral area = (4√3) x 3 = 12√3
