Alexus [3.1K]2 years ago
8 0

Step-by-step explanation:

there is no diagram so I'm just going to guess this however

sin x = 6/9

sin x = 2/3

sin x = 0.67

x = sin inverse of 0.67

x = 42.1

Factorise (x-y)^2-(x-y)^3=?
bogdanovich [222]

Answer:

\left(x-y\right)^2\left(1-x+y\right)

Step-by-step explanation:

You factor out the common term first.

You should get the equation below.

\left(x-y\right)^2\left(1-\left(x-y\right)\right)

then you get rid of the negative inside\left(1-\left(x-y\right)\right)

and will be simplified to this.

\left(x-y\right)^2\left(1-x+y\right)

What is 1/2 + 1/6, please explain, I'm very bad at math
Masja [62]

Answer:

Before adding, we need to make sure the denominators are the same. We can do so by multiplying the fraction by a common multiple. In this case, 3 is a multiple of 6, so we can change 1/2 to 3/6. 3/6 is still equal to 1/2, so nothing changes.

Now we have 3/6+1/6, which is 4/6 (add the numerator).

4/6 can be simplified to 2/3 and 2 is a multiple of 4 and 6.

So, therefore, the answer is 2/3.

Which is the initial value that shrinks an exponential growth function by 50%?
ValentinkaMS [17]
Suppose that the exponential growth function is  y = 4^x.

If x = 1, then y = 4^1 = 4.
If x = 3, then y = 4^3 = 64.

Let the initial value be 1/2.

The growth function is now y = 1/2 * 4^x.

If x =1, then y = 2 which is half of the y value before adding the 1/2.

If x = 3, then y = 1/2 * 64 = 32.

Answer: 1/2
