A(14)=240(1+0.09)^14-1

A(14)=240(1.09)^13

A(14)=240(3.065)

A(14)=735.79

Ben has 57 toys.15 of them are new,9 are his favorite ones, 2 are new and favorite. Ben is going to give away all of his other t
Stells [14]

Answer:

31 toys

Step-by-step explanation:

What we know:

- There are 57 toys in total

- 15 are new

- 9 are Ben's favourite

- 2 are both Ben's favourite and new

Ben is not going to give away toys that are new or favourite. This means that the number of toys he <em>will not</em> give away is equal to 15+9+2.

15+9+2

= 26 toys

He has 57 toys in total, so we can find the number of toys he <em>is</em> going to give away by subtracting 26 from 57.

57-26

= 31 toys

Therefore, he will give away 31 toys.

I hope this helps!

Write the given expression in terms of x and y only. tan(sin^-1(x)+cos^-1(y))
Softa [21]

Answer:

[xy + √(1−x²) √(1−y²)] / [y √(1−x²) − x √(1−y²)]

Step-by-step explanation:

tan(sin⁻¹x + cos⁻¹y)

Use angle sum formula:

[tan(sin⁻¹x) + tan(cos⁻¹y)] / [1 − tan(sin⁻¹x) tan(cos⁻¹y)]

To evaluate these expressions, I suggest drawing right triangles.

For example, let's draw a triangle where x is the side opposite of angle θ, and the hypotenuse is 1.  Therefore:

sin θ = x/1

θ = sin⁻¹x

Using Pythagorean theorem, the adjacent side is √(1−x²).  Therefore:

tan θ = x / √(1−x²)

tan(sin⁻¹x) = x / √(1−x²)

Draw a new triangle.  This time we'll make y the adjacent side to angle θ.

cos θ = y/1

θ = cos⁻¹y

Using Pythagorean theorem, the opposite side is √(1−y²).  Therefore:

tan θ = √(1−y²) / y

tan(cos⁻¹y) = √(1−y²) / y

Substituting:

[x / √(1−x²) + √(1−y²) / y] / [1 − x / √(1−x²) × √(1−y²) / y]

Multiply top and bottom by √(1−x²).

[x + √(1−x²) √(1−y²) / y] / [√(1−x²) − x × √(1−y²) / y]

Multiply top and bottom by y.

[xy + √(1−x²) √(1−y²)] / [y √(1−x²) − x √(1−y²)]
