Answer:

= 40

Step-by-step explanation:

so if you mean x = -8

(x - 2)(x + 4) \times (x + 9) \\

( - 8 - 2)( - 8 + 4) \times ( - 8 + 9)

( - 10)( - 4) \times 1

How many true solutions does the equation sinx=cosx-1 have over the interval 0 is less than or equal to x which is less than or
FrozenT [24]
sinx=cosx-1 \\  \\ 
sinx-cosx=-1

Using the identity: sinx-cosx=- \sqrt{2}cos( \frac{ \pi }{4}+x), we get:

- \sqrt{2}cos( \frac{ \pi }{4}+x)=-1 \\  \\ 
cos( \frac{ \pi }{4}+x)= \frac{1}{ \sqrt{2} } \\  \\ 


There are two solutions to this equation:

1)
\frac{ \pi }{4}+x= \frac{ \pi }{4} \\  \\ 
x=0

Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation

2) 
\frac{ \pi }{4}+x= \frac{7 \pi }{4}   \\  \\ 
x= \frac{3 \pi }{2}

Therefore, there are 3 solutions to the given trigonometric equation.

<span>Given number: Two hundred billion in half, how to write this one in standard form
let us first simplify each statement:
=> two hundred billion = 200 000 000 000
=> in half meaning = half of the given number or divide the given number by 2 to get the answer
=> 200 000 000 000 / 2
Show, the ½ of two hundred billion in standard form
=>  Thus, two hundred billion in half is equals to 100 000 000 000
