M would have a new coordinate of (4,5)
Grace [21]3 years ago
6 0
The current x coordinate is -3. We translate it 7 units to the right, hence the new x coordinate will be 4.

The current y coordinate is 3. We translate it 2 units upwards, hence the new x coordinate will be 5.

So M'(4,5)

If 1 factor of 6x3 + 23x2 − 6x − 8 is (x + 4), what are the other 2 factors?
spin [16.1K]
Use synthetic division to find the quadratic:

-4 | 6 23 -6 -8
6 -24 4 | 8
—————-
6 -1 -2 | 0 = 6x²-x-2 = (3x+1)(2x-1)

So the other two factors are 3x+1 and 2x-1.

2cos5xcos3x+sinx=cos8x
harkovskaia [24]

It looks like your equation (it's not an identity) is

2 cos(5<em>x</em>) cos(3<em>x</em>) + sin(<em>x</em>) = cos(8<em>x</em>)

Recall that

cos(<em>x</em> + <em>y</em>) = cos(<em>x</em>) cos(<em>y</em>) - sin(<em>x</em>) sin(<em>y</em>)

cos(<em>x</em> - <em>y</em>) = cos(<em>x</em>) cos(<em>y</em>) + sin(<em>x</em>) sin(<em>y</em>)

==>   2 cos(<em>x</em>) cos(<em>y</em>) = cos(<em>x</em> + <em>y</em>) + cos(<em>x</em> - <em>y</em>)

so that

2 cos(5<em>x</em>) cos(3<em>x</em>) = cos(8<em>x</em>) + cos(2<em>x</em>)

Then the equation simplifies to

cos(8<em>x</em>) + cos(2<em>x</em>) + sin(<em>x</em>) = cos(8<em>x</em>)

cos(2<em>x</em>) + sin(<em>x</em>) = 0

Also recall that

cos(2<em>x</em>) = 1 - 2 sin²(<em>x</em>)

so the equation is quadratic in sin(<em>x</em>) and can be factorized:

1 - 2 sin²(<em>x</em>) + sin(<em>x</em>) = 0

2 sin²(<em>x</em>) - sin(<em>x</em>) - 1 = 0

(2 sin(<em>x</em>) + 1) (sin(<em>x</em>) - 1) = 0

Solve for <em>x</em> :

2 sin(<em>x</em>) + 1 = 0   <u>or</u>   sin(<em>x</em>) - 1 = 0

sin(<em>x</em>) = -1/2   <u>or</u>   sin(<em>x</em>) = 1

[<em>x</em> = arcsin(-1/2) + 2<em>nπ</em>   <u>or</u>   <em>x</em> = <em>π</em> - arcsin(-1/2) + 2<em>nπ</em>]   <u>or</u>   <em>x</em> = arcsin(1) + 2<em>nπ</em>

(where <em>n</em> is any integer)

<em>x</em> = -<em>π</em>/6 + 2<em>nπ</em>   <u>or</u>   <em>x</em> = -5<em>π</em>/6 + 2<em>nπ</em>   <u>or</u>   <em>x</em> = <em>π</em>/2 + 2<em>nπ</em>

24% of 289 estimated using<br> a rate per 100
zaharov [31]

Answer:

The answer would be 40!

Step-by-step explanation:

Estimating ~ rounding

I would round 24% (20%), and 289 (300).

using the formula:

is/of \\ = %/100,

I'm looking for "IS"

I multiply 20 (just 20, no percent) by 200 = 4000.

Then I divide by 100 to get the "IS".

That's how I got my answer!

Hope this helps!
