What is SIN A?

Mathematics
1 answer:
Bond [772]3 years ago
6 0

Answer:

\sin A =\frac{4}{5}

Step-by-step explanation:

Recall the mnemonics SOH CAH TOA.

SOH means the Sine ratio is Opposite over Hypotenuse.

This implies that;

\sin A =\frac{Opposite}{Hypotenuse}

The side opposite to angle A is 4cm and the hypotenuse is 5cm.

\therefore \sin A =\frac{4}{5}

120 - 36 as a product with the GCF as a factor. True, we can factor out the GCF and we'll have a product:

GCF(120,36) = GCF(5(24),36)=GCF(5(12)(2),12(3)) = 12

We can factor that out and get:

120 - 36 = 12(10 - 3) = 12(7)

Answer: TRUE

How to find the GCF of three numbers.

There are a couple different ways; the obvious way is to find the GCF of the first two and then then GCF of the result and the third.

The other way is to prime factorize all three numbers; for each prime factor count how many times it occurs in each input. In the GCF it will occur the minimum of those three. Multiply the resulting powers of prime factors to get the GCF.

GCF(60,90) = GCF(30(2), 30(3)) = 30

60 + 90 = 30(2 + 3)

Xiao missed a factor of ten in the GCF.

Answer:

f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd

Step-by-step explanation:

We need to determine if the function f(x)= x^3-2x is Even, Odd, or Neither.

Determining if a function f(x) is even or not we put x=-x and check

If f(-x)=f(x) the function is even

if f(-x)= -f(x) the function is odd

So, Putting x =-x and determining if the given function f(x)= x^3-2x is Even, Odd, or Neither.

f(x)= x^3-2x\\Put \ x=-x\\f(-x)=(-x)^3-2(-x)\\f(-x)=-x^3+2x\\f(-x)=-(x^3-2x)\\f(-x)=-f(x)

As f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd

A volleyball of radius 13 inches fits exactly in a cylinder with the same radius. inside the container there is empty space not
asambeis [7]

Volume of Sphere is V=(4/3)*PI*r^3

The radius of the volleyball is 13 inches

<span>So V=(4/3) * 3.14 * 13^3 =  9198 cubic inches</span>

 

Volume of a cylinder is V=pi * r^2 *h

Since they say the ball fits perfectly

The radius is 13 and the height is 26 ( the diameter of the ball)

So V=3.14 * 13^2 * 26 = 13,797 cubic inches

 

13797 – 9198 = 4,599 cubic inches of empty space
